Abstract
The present disclosure relates to compositions and methods relating to reducing the potency of
arthropods using double-stranded RNA and agents to control pests of bees and beehives.
Description
FIELD The present disclosure also relates to compositions and methods relating to reducing the potency of arthropod pests and vectors.
BACKGROUND Bee colony losses are influenced by several factors, among which are Varroa destructor mites (Varroa mites) and bee viruses, which can be transmitted by Varroa mites. Varroa mites are considered to be the biggest threat to managed bee health and they frequently cause .0 unsustainably high bee colony losses if left unchecked. Several treatment options to prevent or treat Varroa mite infestations are available to beekeepers, including synthetic miticides, non selective organic acids, essential oils, and other products. Synthetic products, including pyrethroid, organophosphate, and amitraz-based solutions provide the first line of treatment. However, many of these products have lost, or are losing, efficacy due to rapidly developing .5 resistance. In addition, many synthetic pesticides used to control Varroa mites appear to negatively impact the health of bees.
RNA interference is a promising technology that can be used to control bee viruses and Varroa mites. In order to control Varroa mites in beehives, dsRNA specifically targeting mite genes is applied to a beehive and eventually delivered to Varroa. The active RNA .0 molecules are processed by the Varroa destructor intracellular RNAi machinery, resulting
in Varroa mite mortality and/or disruption of Varroa mite physiological processes, which eventually leads to suppression of Varroa mite population in hives and improves bee colony survival. However, dsRNAs can be rapidly degraded by the microbiota found in beehives, and methods and compositions useful for stabilizing dsRNAs in beehives are needed.

In still another aspect, a bee is Apis mellifera. In a further aspect, a bee is Apis cerana.
The term "bee" refers to all stages of the bee life cycle (e.g., adult bees, larval bees, pupal bees, bee eggs). In one aspect, a bee is an adult bee. In another aspect, a bee is a larval bee. In an aspect a bee is a pupal bee. In another aspect, a bee is a worker bee. As used herein, a "worker bee" refers to a bee that is not a queen bee or a drone bee. For instance, a worker bee can refer to a forager bee or a hive bee. A "drone bee" refers to a male bee that is the product of an unfertilized egg. Without being limiting, the primary role of a drone bee is to mate with a queen bee.
In an aspect, a bee is a forager bee. As used herein, a "forager bee" refers to a bee that leaves a hive or colony to collect and/or scout for water, nectar, pollen, or resin. Typically, forager bees are at least 21 days old. In another aspect a bee is a hive bee. As used herein, a "hive bee" refers to a bee that does not leave the hive to scout for or collect resources. Typically, hive bees are less than 21 days old. Without being limiting, hive bees care for young bees/larvae, feed young bees/larvae, care for the queen bee and/or drones, produce honey, produce royal jelly, produce wax, regulate hive temperature, defend the hive from intruders, and build/repair/clean hive structure (e.g., honeycomb).
In still a further aspect, a bee is a bee of a bee colony. As used herein, a "bee colony" refers to a collection of a queen bee and worker bees. A bee colony can further comprise drone bees. Typically, hive and forager bees of a colony are descendent from the colony's queen, but this is .0 not required of a bee colony. A bee colony can comprise anywhere from I to over 100,000 individual bees, although 20,000 to 60,000 bees is most common.
In an aspect a bee is a bee of a beehive. As used herein, a "beehive" refers to an enclosed, often manmade, structure that houses a bee colony. Without being limiting, a beehive typically comprises a queen bee, hive bees, forager bees, and drone bees. In an aspect, a beehive provided .5 herein comprises a composition provided herein. In one aspect, a beehive provided here comprises an Apis ceranabee or an Apis mellifera bee. In another aspect, a beehive provided herein is infested by at least one mite. In yet another aspect, a beehive provided herein is infested by at least one Varroa destructormite. In still a further aspect, a beehive further comprises a feeder.
.0 The terms "Varroa destructor mite" and "Varroa mite" are used interchangeably to refer to any life stage of the mite species Varroa destructor. Varroa mites are external parasites of Apis cerana and Apis mellifera, although they may parasitize other bee species as well. Adult Varroa mites feed on bee hemolymph and/or brood food in brood cells. Female Varroa mites deposit eggs on larval bees after the brood cell is capped, and the Varroa mite eggs hatch and feed on the developing larval bee.
Bee/Mite Feeding Compositions Bee feeding is common practice amongst bee-keepers, for providing both nutritional and other, for example, supplemental needs. Bees typically feed on honey and pollen, but are known to ingest non-natural feeds as well. Bees can be fed various compositions including, but not limited to Wheast (a dairy yeast grown on cottage cheese), soybean flour, yeast (e.g. brewer's yeast, torula yeast) and yeast products products-fed singly or in combination and soybean flour fed as a dry mix or moist cake inside the hive or as a dry mix in open feeders outside the hive. Also useful is sugar, or sugar syrup. The addition of 10 to 12 percent pollen to a composition to bees improves palatability. The addition of 25 to 30 percent pollen improves the quality and quantity of essential nutrients that are required by bees for vital activity.
Cane or beet sugar, isomerized corn syrup, and type-50 sugar syrup are satisfactory substitutes for honey in the natural diet of honey bees. Isomerized corn syrup, and type-50 sugar syrup can be supplied only as a liquid to bees.

In one aspect, this disclosure provides a method of protecting a nucleic acid molecule from degradation comprising adding at least one food-grade preservative to a composition comprising a carbohydrate and the nucleic acid molecule. As used herein, "protecting" refers to eliminating or slowing the rate of degradation of a starting concentration of a nucleic acid molecule present at a given time point as compared to a non-protected control. For example, without being bound by any scientific theory, the presence of a food-grade preservative in a composition protects a nucleic acid molecule from degradation by bacteria and/or fungi. Without being limiting, a suitable "non-protected" control would be an identical starting amount of the nucleic acid molecule in a composition that lacks a food-grade preservative component.
In an aspect, a method of protecting a nucleic acid molecule from degradation comprises the detectable presence of a nucleic acid molecule in a composition for at least 1, at least 2, at least 3, at least 4, at least 5, at least 6, at least 7, at least 8, at least 9, at least 10, at least 11, at least 12, at least 13, at least 14, at least 15, at least 16, at least 17, at least 18, at least 19, at least 20, at least 21, at least 22, at least 23, at least 24, at least 25, at least 30, at least 35, at least 40, at least 45, at least 50, at least 55, or at least 60 days longer as compared to a composition lacking the at least one preservative.
pH ("potential of hydrogen") is measured on a logarithmic scale, generally from 1 to 14, although higher and lower pH values are possible. pH is the negative base 10 logarithm of the .0 molar concentration of hydrogen ions in a solution. A solution with an equal number of hydrogen and hydroxide ions has a pH value of 7.0 and is considered to be "neutral." Without being limiting, an example of a neutral solution is pure water. pH values below 7.0 contain more hydrogen ions than hydroxide ions and are considered to be "acidic." pH values above 7.0 contain more hydroxide ions than hydrogen ions and are considered to be "basic" or "alkaline." .5 Methods of determining the pH value of a solution are known in the art. Without being limiting, methods suitable for determining a pH value include indicator strips (e.g., litmus paper), indicator dyes, hydrogen-electrode methods, quinhydrone-electrode methods, antimony electrode methods, and glass-electrode methods.

.0 dsRNAs to Target Mites
It has been shown that nucleic acid molecules can be provided in a diet to Varroa mites to down regulate the expression of a Varroa mite gene product. See, for example, U.S. Pat. Nos. 8,962,584; 9,540,642; and 9,662,348, each of which is incorporated by reference herein in its entirety. Non-limiting examples of gene products include messenger RNAs (mRNAs), proteins, .5 and small RNAs. Nucleic acid molecules that are complementary to Varroa mite gene products can be used to cause mortality of a Varroa mite, to reduce the fecundity of a Varroa mite, to prevent Varroa mite infestation of a beehive, to treat a Varroa mite infestation of a beehive, or make a Varroa mite more susceptible to additional treatments that cause mortality of a Varroa mite (e.g., commercial miticides).
As used herein, the term "fecundity" refers to the ability to produce offspring; higher fecundity refers to the ability to produce more offspring, while reduced fecundity refers to the ability to produce fewer offspring. For example, without being limiting, an untreated Varroa mite may lay up to six eggs, while a Varroa mite treated with a composition provided herein with reduced fecundity may only lay up to five eggs. In an aspect, a method provided herein comprises reducing the fecundity of an arthropod. In another aspect, a method provided herein comprises reducing the fecundity of a mite. In a further aspect, a method provided herein comprises reducing the fecundity of a Varroa destructormite.
In an aspect, reduced fecundity comprises a reduction in mite egg production in a beehive or bee colony of at least 1%, at least 5%, at least 10%, at least 20%, at least 30%, at least 40%, at least
50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 100% as compared to mite egg production an untreated control beehive or bee colony. In an aspect, reduced fecundity comprises a reduction in Varroa destructor mite egg production in a beehive or bee colony of at least 1%, at least 5%, at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or at least 100% as compared to Varroa destructor mite egg production an untreated control beehive or bee colony.
In an aspect, reduced fecundity comprises a below replacement rate level of reproduction. In an aspect, reduced fecundity comprises a replacement rate level of reproduction. As used herein, "replacement rate" refers to the fertility rate at which female mites produce enough offspring to .0 sustain or maintain the population level in a beehive or bee colony. In the absence of female mortality between birth and the end of egg-laying, the replacement rate would be approximately 2. However, due to non-zero mortality rates, replacement rates are often higher than 2. For example, if the replacement rate is 2, a female Varroa destructormite would need to produce 2 offspring to maintain the population level. If the replacement rate is 2, a female Varroa .5 destructor mite that produces 3 offspring would be reproducing at a rate above the replacement rate.

As used herein, an "agent to control mites" refers to any composition that can be used to cause mortality or stunting of a mite, reduce the reproductive rate or success of a mite, reduce the feeding frequency or duration of a mite, reduce the mobility of a mite, disrupt the rest pattern of a mite, perturb the life cycle of a mite, prevent or slow molting of a mite, or any combination thereof. In an aspect, an agent to control mites comprises a miticide. In an aspect, an agent to control mites comprises an essential oil. In an aspect, an agent to control mites comprises a non selective organic acid. In an aspect, an agent to control mites comprises an aqueous solution. In another aspect, an agent to control mites comprises a liquid. In another aspect, an agent to control mites comprises a powder.
As used herein, a "miticide" refers to any chemical agent that is injurious or lethal to a mite. A miticide can cause mortality of a mite; reduce the lifespan of a mite; reduce or eliminate the reproductive capabilities of a mite; or any combination thereof. Non-limiting examples of miticides include Apivar@ (amitraz), Apistan@ (fluvalinate), CheckMite+@ (coumaphos), Hivastan@ (fenpyroximate), Sucrocide@, Apiguard@/Thymovar@ (thymol), ApiLife Var@, Mite-Away Quick Strips®(formic acid), formic acid, oxalic acid, and HopGuard@ II (hops beta acids).

Bee colonies in temperate regions typically undergo changes in their population size as the year progresses. In winter, bee colonies reduce their metabolism, referred to as the "dormant phase," and few to no new offspring are being produced. As spring begins, the bee population increases exponentially (the "population increase phase") before peaking (the "population peak phase") .5 sometime during the summer. As autumn approaches, the population of the colony declines (the "population decline phase)" before returning once again to the dormant phase in winter. Those in the art will appreciate that these phases can be skewed, depending on geographic location and environmental factors, such that the population peak phase could occur in spring or autumn, and that the population decline phase could begin in winter, and the population phases are not tied to .0 particular seasons or months of the year.
These phases can also be skewed by honey flow. As used herein, "honey flow" refers to a time period when one or more major nectar sources in bloom and the weather is favorable for bees to fly and collect nectar in abundance. Depending on the geographic location and local climate, honey flow can peak in the spring, summer, or autumn. Honey flow can last anywhere from a few days to many weeks. In one aspect, honey flow occurs during spring. In another aspect, honey flow occurs during summer. In a further aspect, honey flow occurs during autumn.

Having now generally described the invention, the same will be more readily understood through reference to the following examples that are provided by way of illustration and are not intended to be limiting of the present invention, unless specified.
EXAMPLES .0 Example 1 A. Preparation of Citric Buffer A citric acid -Na2HPO4 buffer (citric buffer) was prepared from 0.1 M citric acid monohydrate (C 6 H 80 7 .H2 0) and 0.2 M sodium phosphate dibasic (Na2HPO4) stock solutions. A working citric buffer stock solution of pH 5.3 was created by combining 44.25 mL of 0.1 M citric acid monohydrate with 55.75 mL of 0.2 M sodium phosphate dibasic.
The citric buffer was used to adjust and stabilize the pH of several bee and/or Varroa destructormite ingestible compositions comprising sucrose and a trigger nucleic acid. Several dilutions of the citric buffer stock were tested (Table 1) to determine how much citric buffer is required to obtain at a pH as close to 5.4 as possible. pH values below 5.5 are desired because .0 sodium benzoate and potassium sorbate are known to be most effective at acidic pH values.

It was determined that potassium sorbate has low solubility in citric buffer, so a second working stock with a higher concentration was produced in ddH20 (Table 4). This minimized the volume of potassium sorbate that would need to be added to the final compositions and thus would not influence the final pH of the compositions.

C. Preparation of Beehive Microbiota Contaminating stock was generated by collecting natural contaminators from 10 beehive feeders. This was done by shaking 1 liter of 30% sucrose solution in empty beehive feeders for approximately two minutes, then collecting the sucrose solution. The collected solutions were incubated at 350 C. for four days. The sucrose solutions were visibly contaminated at this point.
Approximately 20 pL from each sucrose solution was spread on different LB TSA (Luria Bertani trypticase soy agar) agar plates to confirm the viability of bacteria in the sucrose solutions. Similarly, approximately 20 pL from each sucrose solution was spread on different SDA (Sabouraud dextrose agar) agar plates to confirm the viability of fungi in the sucrose solutions.
After confirming that all sucrose stock solutions were viable, all 10 contaminated sucrose stock solutions were combined and homogenized. The combined stock contamination solution was divided into approximately 800 mL aliquots and centrifuged at 6000xG for 10 minutes at 4 C. to recover a pellet of microorganisms. The supernatants were removed and the recovered pellets were then resuspended in 10 mL of1xPBS (phosphate buffered saline) and divided into 1 mL aliquots.
The 1 mL aliquots were again centrifuged at 6000xG for 10 minutes at 4 C. to recover pellets after the removal of the supernatant. The pellets were divided into three groups to determine the optimal storage conditions for the contamination stock: (1) dry pellet; (2) pellet resuspended in .0 500 pL of 50% glycerol prepared in 1xPBS; and (3) pellet resuspended in 500 pL of 50% glycerol prepared in ddH2 0. All of the pellets were then frozen overnight at -80° C.
An aliquot from each storage group was thawed on ice. The dry pellet was resuspended in 1 mL 1xPBS, while 500 pL of1xPBS was added to the pellets in in glycerol from groups (2) and (3) before resuspending the pellets in solution. Starter cultures were grown in 5 mL of sterile LB .5 broth at 370 C., shaking at 200 rpm, for 4 hours. Optical density at 600nm (OD 6 00) was measured for each sample. See Table 5.

Approximately 20 pL of contamination stock from each storage method starter culture, and approximately 20 pL of the resuspended pellets, were plated on both TSA and SDA plates and allowed to grow overnight at 37° C. to again confirm the viability of the contamination stocks.
D. Testing the Ability of Food Grade Preservatives to Enhance dsRNA Stability
The trigger nucleic acid molecule (SEQ ID NO: 1, see Table 6) tested herein comprises 376 nucleotides (CAM376). CAM376 is homologous to a Varroa destructorcalmodulin gene and is nearly identical to SEQ ID NO: 3 (SEQ ID NO: 3 comprises deletions at nucleotide positions 109, 200, 239, and 270 of instant SEQ ID NO: 1) from U.S. Pat. No. 9,540,642, (which is incorporated by reference herein in its entirety), which has been shown to down-regulate expression of a calmodulin gene in Varroa destructor. A working stock of 20 mg/mL was prepared in citric buffer (pH 5.3).

Contamination Stock pellets from Group (1) in Example IC were resuspended in 1 mL of 1x phosphate buffered saline (PBS) on ice, then the eluted Contamination Stock was added to each Formulation of Table 7 to a final concentration of 80x (12.5 p1L/mL).
In order to test the stability of CAM376 in each Formulation, each Formulation was divided into triplicate (3 mL/replicate; 9 mL total) and kept in a 35 C. water bath. At several time points (Day 0, Day 4, Day 7, Day 10, Day 14, Day 17, and Day 21) a 100pL was removed from each replicate from Formulation.
Each 100 pL aliquot was diluted with 300 pL of ddH 20. From the diluted aliquots, 100 pL was used for ultra-pure liquid chromatography (UPLC) for quantitative measurement, and 4 pL was loaded into a 2% TAE agarose gel for quantitative/qualitative measurement (see FIG. 1). UPLC measurements were taken for Day 0, Day 4, Day 7, and Day 10 (see FIG. 2 and Table 8). For Day 0, only one UPLC measurement was taken prior to splitting the original Formulation into triplicates.

CAM376 degenerated rapidly in Formulation #1 and was not detectable via UPLC or agarose gel by Day 7 (Table 8; FIGS. 1C and 2). Similarly, CAM376 degraded quickly in Formulation #3, and was not detectable via UPLC or agarose gel by Day 10 (Table 8; FIGS. 1D and 2). CAM376 degraded more slowly in Formulations #2, #4, and #5, and non-degraded DNA was still detectable via UPLC on Day 10 (Table 8; FIG. 2) and via agarose gel on Day 20 (FIG. 1G).
The results demonstrate that the addition of sodium benzoate and potassium sorbate prolong the life span of nucleic acid molecules when subjected to the natural microbiome present in beehive feeders.
Example 2. Testing the Ability of a Single Food-Grade Preservative to Protect a dsRNA Four additional formulations were created to test the ability of sodium benzoate alone to protect a dsRNA from degradation. See Table 9. Sodium benzoate was prepared in a solution with a pH of 4.5.

Contamination Stock from Example 1C was eluted in 1 mL of1x phosphate buffered saline (PBS) on ice, then the eluted Contamination Stock was added to each Formulation of Table 8 to a final concentration of 80x (12.5 tL/mL).
In order to test the stability of CAM376 in each Formulation, each Formulation was divided into triplicate (3 mL/replicate; 9 mL total) and kept in a 35 C. water bath. At several time points (Day 0, Day 5, Day 7, Day 14, Day 21, Day 28, and Day 35) a 100pL was removed from each replicate from Formulation.
Each 100 pL aliquot was diluted with 300 pL of ddH20. From the diluted aliquots, 100 pL was .0 used for ultra-pure liquid chromatography (UPLC) for quantitative measurement, and 4 tL was loaded into a 2% TAE agarose gel for quantitative/qualitative measurement (see FIG. 1). UPLC measurements were taken for Day 0, Day 4, Day 7, and Day 10 (see FIG. 2 and Table 7). For Day 0, only one UPLC measurement was taken prior to splitting the original Formulation into triplicates.
The dsRNA in Formulation 6 (66% sucrose) degraded steadily and was almost undetectable by Day 28. See FIGS. 3A and 4A. The dsRNA in Formulation 7 (66% sucrose and 0.1% sodium benzoate) also degraded steadily, although some dsRNA was still detectable by both UPLC and agarose gel at Day 28 and Day 35. See FIGS. 3B and 4B. The dsRNA in Formulation 8 (80% sucrose) was detectable at all time points measured, although the dsRNA degraded over time. See FIGS. 3C and 4C. The dsRNA in Formulation 9 (80% sucrose and 0.1% sodium benzoate) also degraded over time, but Formulation 9 retained the highest amount of dsRNA of these four
Formulations at Day 35. See FIGS. 3D and 4D. Notably, the addition of a second food-grade preservative (e.g., potassium sorbate) in Example 1 above further improved the stability of dsRNAs over time.
Example 3. Combining and Comparing dsRNAs Complementary to Varroa Mite mRNA and Miticide Treatment Treating beehives with miticides and double-stranded RNAs complementary to Varroa destructor mRNA may be advantageous in treating or preventing a Varroa destructormite infestation of a beehive.
dsRNAs Targeting Varroa Calmodulin mRNA Augmented a Common Miticide Treatment
.0 Four treatment groups were set up to determine whether CAM373 (SEQ ID NO: 2) dsRNAs complementary to the Varroa destructor mite for the Calmodulin mRNA can augment Apivar@ treatment to prevent and/or reduce a Varroa destructor mite infestation of a beehive. Each beehive is naturally infected with Varroa mites prior to the start of the experiment.
A general scheme of delivery for this protocol can be seen in FIG. 5. Four distinct treatments .5 were provided. In the first group, the miticide Apivar@ (amitraz) is provided as a plastic strip imbibed in the active amitraz as a one strip for each five frames to 40 beehives in Spring and again in Fall for a total duration of six weeks for each treatment. In the second group, Apivar@ was first provided alone in the Spring and subsequently, Apivar@ and a composition comprising the dsRNA (consisting of a 500 mL solution of 80% sucrose mixed with 1 gram of SEQ ID NO: 'O 2 dsRNA) were provided to 40 beehives together in Fall. In the third group, Apivar@ and a composition comprising the dsRNA were provided to 40 beehives in both Spring and Fall. In the fourth group, Apivar@ and a composition comprising the dsRNA were provided to 40 beehives in Spring, while the Apivar@ only treatment was given in Fall. The Apivar+dsRNA treatments are delivered simultaneously to the hive and replaced every six weeks. The number of mites in the beehives and the strength of the beehives (e.g., the number of bees present) were assessed at weeks 1 (A1), 7 (A2), 13 (A3), 18 (A4), 24 (A5) and 29 (A6). The main goal for the combined treatment was to keep the mite population below threshold. The threshold is established by the number of mites which will damage the hive. Historically, this threshold is set at five mites per one hundred bees (5 m/100 b). At the conclusion of 24 weeks (time point A5) the percent hives with more than five mites per one hundred bees was measured (FIG. 6). This measurement revealed that the Apivar@ plus dsRNA treatment (treatment A.) resulted in significantly less hives with levels of mites above threshold.
Additionally, a breakdown of the data into Spring and Fall individual treatments revealed that the miticide+dsRNA treatments together provided better mite control than the miticide treatment alone (FIG. 7).
At the completion of the field trial, colonies were assessed for hive strength by counting the number of frames that were covered by at least 75% with living bees. This provides a reasonable estimate of the number of bees in the colony. On average, colonies treated with Apivar and dsRNA had approximately twenty percent (20%) more bees than those that had received the Apivar only treatment (FIG. 8).
