NOVEL SOLID ΒΑΓΓ COMPOSITIONS USED FOR PROTECTING FRUITS FROM FRUIT FLYPESTS
FIELD OF THE INVENTION
The présent invention relates generally to the field of agricultural technology and more specifically to novel green solid bait compositions and their use thereof for protecting fruits from fruit fly pests.
BACKGROUND OF THE INVENTION
Tephritidae is the true fruit flies family, which includes about 4000 species arranged in 500 généra. This family is considered as the most economically important dipteran family. The pests within this family are those that attack soft fruits.
Females of these species lay eggs under the fruit skin and the larvae develop in the fruit. Mature larvae leave the rotten fruit or fall with it to the ground where the larvae look for a hiding place to pupate.
Most control strategies are being applied against the adult phase of the Aies. The most important tephritid species belong to the généra Anastrepha, Bactrocera, Ceratitis, Dacus and Rhagoletis. About 70 species are considered important agricultural pests and many others are minor or potential pests. The hosts of these flies belong to a wide variety of families of plants and include many major commercial crops.
Fruit flies cause enormous économie damage because they attack valuable commercial fruits and hâve the ability to disperse and exist in régions far from their original and natural habitat. For example, the Mediterranean fruit fly initiated in Africa and today is found in Australia, Europe, America (north and south) and Asia. Strict quarantine régulations are imposed on export countries in order to stop any further distribution. These quarantine régulations force the farmers that wish to export crops to apply intensive and expensive control Systems to withstand these quarantine standards.
There are two important fruit fly pests in Israël: the Mediterranean fruit fly and the olive fruit fly. Recently two severe quarantine species hâve reached Israël: the lesser pumpkin fly and the peach fruit fly. Actions must be presently taken to stop further
distribution of these species in Israël and toward Europe.
The most common and efficient system to control the fruit fly populations for more than 50 years is poison-bait sprays. The hait is a protein-based product fulfilling the need for protein of newly emerged females. The poison is mainly the organo-phosphorous Malathion.
Malathion is a cheap and efficient poison having relatively high LD5o to warm blooded animais and it is thus safer to humans. Malathion has been used for more than 60 years and it is regarded as one of the most efficient poisons in the market.
The rôle of the bait is to reduce insecticides cost as well as the environmental contamination. However, due to the présent strict régulations with respect to the content of residues of insecticides in food, crops contaminated with Malathion cannot be marketed.
Possible alternatives to using Malathion sprays are products such as Success, which is much more expensive (typically four times more expensive). Success is a ready-made marketed blend of Spinosad (biological insecticide safe to warm-blooded animais including humans) and a bait.
The use of traps can also keep fruits clean from insecticides. There are several options of baited traps in the market. Some known examples of traps are: Biofeed, onpal and Biolure. However, the common disadvantage of these devices is the high costs of the traps.
Another technique, which is still experimental, is the SIT (Stérile Insect Technique). This technique can work today only with the support of the other control Systems.
Thus, in spite of the variety of control Systems that are sold in the market, the fruit fly problem still exists and there is a need in the art for more efficient and not expensive methods to control fruit fries whilst keeping the fruits and the environment poisonousfree.

DETAILED DESCRIPTION OF THE INVENTION
The inventors of the présent invention hâve developed a novel technology using fruit fly solid bait composition, which is applied as a paste or hanged on a tree branch, thus it has no contact with the fruit. The said solid bait composition is characterized in that it is stronger than other commercial baits and it is long lasting (at least 3 weeks).
Thus, the présent invention provides a novel technology using low cost constituents, so the simple and cheap production contributes to the low price of the said solid bait composition.
The présent invention provides a technology, which is environmentally friendly, or green in addition to being a cheaper technology then other available technologies.
According to an embodiment of the présent invention, the said solid bait composition comprises an attractant or mixture of attractants, phagostimulants and an insecticide imprisoned in a core polymer or combination of polymers, a clay which can be a hydrated silicate, a sait, a humectants or combination of humectants and water.
According to an embodiment of the présent invention, the said solid bait composition comprises an attractant or mixture of attractants, phagostimulants and an insecticide imprisoned in a core polymer or combination of polymers, a clay which can be a hydrated silicate, a sait, a humectants or combination of humectants and water
According to an aspect of the présent invention, the use of the solid bait without a trap reduces fruit Aies control expenses.
According to another aspect of the présent invention, the said solid bait may be used to control many species of fruit Aies that are considered important agricultural pests. In Israël, the said bait can be used to control, e.g., two cardinal pests: the Mediterranean fruit Ay (hereinafter or hereinbefore medAy) and the olive fruit Ay and two quarantine pests: the lesser pumpkin Ay and the peach fruit Ay.
According to another aspect of the présent invention, the said solid bait composition is characterized also in that in includes an ammonia releasing compound or mixture of compounds, which is the key attractant for the fruit Aies.
Thus, the attractant component is an ammonia releasing substance selected from ammonium acetate, ammonium bicarbonate, ammonium carbonate, ammonium citrate, ammonium sulfate, ammonium nitrate, ammonium hydroxide, ammonium carbamate, acetamide and combinations thereof.
According to another aspect of the présent invention, the attractant component (ammonia) is being released from the solid bait surface by diftusion in a controlled rate along a period of time.
According to another aspect of the présent invention, the said solid bait composition consists of water soluble components in an aquatic solution, wherein the characteristics ofthe said solution were examined by the inventors of the présent invention and found superior in comparison to several comparable commercial baits.
According to another aspect of the présent invention, the addition of phagostimulants such as carbohydrates, proteins, amino acids, nucleic acids and lipids contribute to the feeding stimulation of the said solid bait composition.
As used herein the term Stérile Insect Technique (SIT) is a method of biological control whereby a large number of stérile male insects are released and compete with the wild males for female insects. Since most of the males are stérile, when a female mates with the male then it will hâve no offspring, thus the next generation's population will be reduced. However, the stérile males are inferior to the wild males in getting mates, thus
the SIT method is only partly efficient and cannot be used alone to replace the conventional methods.
As used herein, the term phagostimulant (based on the Greek word phagein meaning to eat) refers to compounds that stimulate feeding of, e.g., pests, such as carbohydrates, proteins, amino acids, nucleic acids and various lipids that are potential nutrients.
The term humectant, as used herein, referrs to a hygroscopic substance having a molécule with several hydrophilic groups, most often hydroxyl groups, which has the affinity to form hydrogen bonds with molécules of water.
According to another aspect of the présent invention, the insecticide, which ultimately tums the bait gel composition to be poisonous, is selected from biological pest control agents such as Spinosad, organophosphates such as Acephate, Azinphos-methyl, Bensulide, Chlorethoxyfos, Chlorpyrifos, Chlorpyriphos-methyl, Diazinon, Dichlorvos (DDVP), Dicrotophos, Dimethoate, Disulfoton, Ethoprop, Fenamiphos, Fenitrothion, Fenthion, Fosthiazate, Malathion, Methamidophos, Methidathion, Mevinphos,
Monocrotophos, Naled, Omethoate, Oxydemeton-methyl, Parathion, Parathion-methyl, Phorate, Phosalone, Phosmet, Phostebupirim, Phoxim, Pirimiphos-methyl, Profenofos, Terbufos, Tetrachlorvinphos, Tribufos and Trichlorfon, carbamates such as Aldicarb, Bendiocarb, Carbofuran, Carbaiyl, Fenoxycarb and Methomyl, pyrethroids such as Allethrin, Bifenthrin, Cyhalothrin, Cypermethrin, Cyfluthrin, Deltamethrin, Etofenprox, Fenvalerate, Permethrin, Phenothrin, Prallethrin, Resmethrin, Tetramethrin, Tralomethrin and Transfluthrin or IGRs (Insect Growth Regulators) selected from Nylar, Precor, Methoprene and Hydroprene and a combination thereof.
Preferably FREE, the insecticide is a pest control agent such as Spinosad or an organophosphates such as, Malathion and a combination thereof.
According to another aspect of the présent invention, the aquatic solid bait acquires its solidness by being imprisoned in a net composed of a clay and a polymer.
According to another aspect of the présent invention, the clay is selected from hydrated silicates, silicoaluminates, dickite, bentonite, halloysite, kaolin or kaolinite, montmorilionite and combinations thereof.
According to another aspect of the présent invention, the polymer, which can be a polysaccharide, is selected from alginate, sodium alginate, hydroxypropyl methylcellulose, hydroxypropyl cellulose, cellulose hydrogel, methyl cellulose, ethyl cellulose, or cellulose esters such as cellulose acetate, pectin, chitosan and the like and combinations thereof.
According to another aspect of the présent invention, the humectant can be selected from sorbitol, glycérine, ethylene glycol, propylene glycol, erythrithol and the like and combinations thereof.
According to another aspect of the présent invention, the sait is typically an inorganic sait selected from sodium chloride, potassium chloride, calcium chloride, barium chloride, lithium chloride, sodium sulfate, and the like and combinations thereof.
According to another embodiment of the présent invention, a preferred solid bait composition is created by combining a polymer such as alginate, pectin or chitosan with clays such as kaolinite and/or montmorilionite, including an insecticide such as Malathion or Spinosad and a combination thereof, an attractant or mixture of attractants such as ammonium carbonate or ammonium citrate, a sait such as calcium chloride, humectants such as glycerol and/or ethylene glycol and water.
According to another embodiment, the présent invention provides a method of controlling fruit fly pests comprising exposing the said fruit fly pests to an effective amount of insecticide, which is contained in the solid bait composition described herein.
The présent invention uses an olfactometer for the purpose of testing the solid bait compositions described herein, wherein the said olfactometer detects female captures by the response of the fries towards different odors that can be measured and be compared. The olfactometer was developed and described by Gothilf and Galun (1982), in Olfactometer and trap for evaluating attractants for the Mediterranean fruit fly, Ceratitis Capitata. Phytoparasitica 10, 79-84.
Thus, the présent invention provides herein a novel solid bait composition, which can be efficiently used to control fruit Aies, having an ammonia releasing attractant, wherein
Figure 1 depicts the female captures in olfactometer by 6 different solid bait compositions
(marked A-F) containing constant quantity of attractant along tnne. It may be understood from the results that these compositions préserves their activity along time.
Experiments carried out with solid bait compositions containing different use levels of various attractants, marked as I-IV, are depicted in Figure 2-5.
The example depicted in Figures 2-5 details two solid bait composition prototypes that include an ammonia releasing compound as the attractant, commercial bait as a phagostimulants source and an insecticide, Malation or tracer.
The amount of each component was determined after several sériés of tests for determining the optimal dosages. The laboratory control tests were carried out in round disposable 10 cm diameter plastic boxes. Each box contained 10 protein-deprived medfly females. Poisonous baits were smeared each on a transparency sheet eut to pièces of 1 x 2 cm. Sheet pièces with bait were left under field conditions between tests. A piece of sheet with the bait was hung under the interior surface of box cover. The Aies were exposed to the bait for 3 hours and mortality was recorded every 10 minutes.
Figure 6 depicts female captures observed in olfactometer by solid bail composition containing water and aquatic solution of a commercial bait plus 3 different amounts of attractant I.
Figure 7 depicts the percentage of mortality of protein-derived medfty females in the novel carrier having ammonia releasing substance as attractant, phagostimulants and different tracer concentrations.
Figure 8 depicts the percentage of mortality of protein-derived medfty females in the novel carrier having ammonia releasing substance as attractant, phagostimulants and different malathion concentrations.
EXAMPLE
This example details two bait composition prototypes that include an ammonia releasing compound as the attractant, commercial bait as a phagostimulants source and an insecticide, Malation or tracer.
The amount of each component was determined after several sériés of tests for determining the optimal dosages. The laboratory control tests were carried out in round disposable 10 cm diameter plastic boxes. Each box contained 10 protein-deprived medfty females. Poisonous baits were smeared each on a transparency sheet eut to pièces of 1 x 2 cm. Sheet pièces with bait were left under field conditions between tests. A piece of sheet with the bait was hung under the interior surface of box cover. The Aies were exposed to the bait for 3 hours and mortality was recorded every 10 minutes
