Support, change a foodstuff within every 3 days.Observation larva grow and a situation arises for pest and disease damage.
(Two)As a result with analysis
The influence that 2.1 different humidities are developed to larval growth
It the results are shown in Table 2, it can be seen that foodstuff degree of metamorphism and larva infection muscardine degree are different under different humidity, accordingly
Survival rate it is also variant.90% RH(Relative humidity)Under, carrot degree of metamorphism is more serious, and under high humidity muscardine to children
The infection rate of worm is high so that its survival rate is less than 40%;During 75% RH, the larva often spinning not positive feeding in the room of building; 85% RH
When, carrot, which easily goes mouldy, influences the appetite of larva, therefore survival rate is relatively low under both humidity, and only 40%~70%.Consider food
Expect the factors such as degree of spoilage, larva infection rate and survival rate, it is most appropriate to choose 80% RH as the humidity of larva raising
's.
Note:Carrot is rotted and muscardine infection be respectively divided into "-,+,++ ,+++" 4 grades, wherein "-" represents
Without rotten or infection;"+" represents low-grade infection, infection rate≤15%;"++ " represents grade and moderate infection, infection rate 16%~30%;“+
++", represents severe infection, infection rate >=31%.Survival rate have "+,++ ,+++" 3 grades, wherein "+" represents survival rate
≤40%;"++ " represents survival rate 41%~70%;"+++" represents survival rate >=71%.
Influence of 2.2 different temperatures to growing
Eight thermogrades the results are shown in Table 3 to huge furuncle bat moth larvae Survival Effects.As can be seen that in 8 DEG C -22 DEG C of five temperature
The lower survival rate of larvae of degree is all higher, especially with 19 DEG C of survival rate highests(91.7%), difference is not notable between five temperature, but is raising
Found in supporting as temperature rise larval feeding is more positive:Larval feeding at 8 DEG C is micro, and not brill moth carrot;At 13 DEG C
Larva can gnaw along carrot periphery;Larval feeding enlivens at 16 DEG C, and the related carrot chip knitmesh that can often spin;19 DEG C and 22
DEG C except having and in addition to 16 DEG C of identical habits, feeding is more positive.Though larva feeding is still actively active at 25 DEG C, 28 DEG C and 31 DEG C,
Carrot is more easy to corruption, and is gradually reduced with the rise survival rate of temperature, and larva extremely difficult survival when temperature reaches 31 DEG C, and 16
It rises just has worm to start death successively, all dead to 31 DEG C at the 60th day of larvas.Survival rate otherness between each temperature shows
Write.
Note:Lowercase is different after data, represents to examine through Duncan ' s, the significant difference in 0.05 level;Alphabetical phase
It is same then represent difference it is not notable, similarly hereinafter.-- indicate no worm.Index represents composite index.Similarly hereinafter.
Influence from the different temperatures of table 3 to huge furuncle bat moth percentage of pupation can be seen that percentage of pupation highest at 19 DEG C, 22 DEG C, point
Not Wei 73.7% and 75.0%, and difference is not notable between two temperatures, and the significant difference between remaining each temperature;And when identical
Larva can not complete to pupate at interior 8 DEG C, 13 DEG C, 31 DEG C, hence it is evident that be different from other five temperature.Percentage of pupation at a temperature of remaining
Sequentially it is:It is 16 DEG C of 25 DEG C of >, 28 DEG C of >, respectively 47.4%, 42.6% and 30.4%.
Impact analysis result from different temperatures to huge furuncle bat moth eclosion rate(It is shown in Table 3), eclosion rate reaches at 19 DEG C
92.9%, it is significantly higher than other temperature, next to that 22 DEG C and 25 DEG C, respectively 72.2% and 62.5%;Eclosion rate at 16 DEG C is
33.3%, 28 DEG C only 16.7% of pupa can normally sprout wings, and belly sky is shown as after the pupa that can not sprout wings under this two temperatures about 40d
It is flat, dead.
The change of the female adult that can normally sprout wings egg laying amount at a temperature of 16 DEG C -28 DEG C, spawning is poor between the Different Individual of female adult
It is different larger, ovum amount by 2000/female to 8331/it is female, but between four temperature studied emerging adult egg laying amount
Without significant difference.
The development duration of huge furuncle bat chrysalis is influenced by temperature substantially(It is shown in Table 4), when temperature is increased to 25 DEG C by 16 DEG C,
Pupa goes through the phase and also shortened intimate half the time to 34.4 days by 60.3 days.Therefore, by controlling temperature pupa time can be made to shorten or prolong
It is long.
Note:"-", which represents to have no at this temperature, pupates.
Analysis learns that under the conditions of 19 DEG C and 22 DEG C, huge furuncle bat moth larvae survival rate, percentage of pupation and eclosion rate are all more than
Of a relatively high, pupa time is shorter, and the significant difference between other temperature, is larva and optimal temperature conditions that pupa grows.
Meanwhile 22 DEG C of than 19 DEG C pupa time of pupa time are short 10 days, therefore, according to being actually needed, can set the storage temperature of pupa and make pupa time
Shorten or extend, especially female adult can lay eggs on the day of sprouting wings, to improve the rate of fertilization of ovum, when depositing pupa for 19 DEG C~22 DEG C,
It is necessary the male pupa storage temperature pupated on the same day being higher than female 1~2 DEG C of pupa.
The influence that 2.3 DIFFERENT FEED formulas grow to huge furuncle bat moth
DIFFERENT FEED formula the results are shown in Table 5 to huge furuncle bat moth eclosion rate, it can be seen that several feeds of the invention can raise
Huge furuncle bat moth, the carrot group of survival rate of larvae relatively control is high, is by high order on earth:Feed I=Feed II>Feed II I>
Feed IV>Control group(Carrot).
Meanwhile from table 5 it can also be seen that several man-made feeds for developing of the present invention are raised after huge furuncle bat moth larvae pupates, pupa plumage
Rate is above or approached with control group carrot.
Based on the above effects(Weighed with composite index), several feed formulas raise huge furuncle bat moth, and effect is most preferably matched somebody with somebody
Square II, formula III take second place, and be formulated I and formula IV it is although relatively low, it is also substantially higher than control group carrot.
Influence of 2.4 DIFFERENT FEEDs to huge furuncle bat moth egg amount
6 are the results are shown in Table, compares the pupa of the pupa of larvaization, the pupa of field acquisition and carrot control group that each feed is raised,
After emergence, the egg laying amount interindividual variation of female adult is larger, is without significant difference, the descending order of egg laying amount between each group:Raise
Expect I>Feed IV>Feed II I>Control, field, Feed II.
Note:Lowercase is identical after data, represents to examine through Duncan ' s, difference is not notable in 0.05 level.
As can be seen that several man-made feeds formulas, disclosure satisfy that the normal growth and development needs of larva, man-made feeds quality
It is moderate, be advantageous to larva brill moth feeding, and corruption is not easy, reduce and often change injury of the feed to polypide, either larva is deposited
Motility rate, percentage of pupation and eclosion rate are significantly better than carrot control group, the egg laying amount of the huge furuncle bat moth of different formulations foodstuff raising
It is higher than or close with compareing.The labor workload for frequently changing feed is more importantly greatly reduced, time saving and energy saving saving of labor saves
Money.
2.5 artificial feeding pest species and its preventing and treating
Found in the feeding process of huge furuncle bat moth, muscardine and acarid are the main diseases and insect pests during artificial feeding, wherein in vain
Stiff bacterium is the main factor for causing larva and pupa death, and propagation and speed of catching an illness are fast, is that prevention is most needed in breeding process
Natural enemy.During the artificial feeding disposed within of larva that field is excavated, if take effective prophylactico-therapeutic measures to have infection muscardine rate
Significantly affect(It is shown in Table 7), it is sterile-processed after the parasitic rate of muscardine be reduced to 4% by 25%, after processing the parasitic rate of acarid by
50% is reduced to 19%.When acarid is more by feeding or cleaning, because vessel, tweezers or foodstuff carry and parasitize on polypide.
Note:Carrot is raised, and the feeding time under two processing is 45d.
For above-mentioned pest and disease damage and lethal factor, the main prophylactico-therapeutic measures taken has:
(1)Sterilized water will be used by providing the humidifier of humidity, avoid pollution of the miscellaneous bacteria to air in climate box in steam.Humidifier
Also often to clean, reduce mould in bottom tub and connection growth cabinet breather pipe growth.
(2)Feed is changed in time and changes blake bottle.Substituting feed such as carrot will ensure to change once for every 3 days, artificial to raise
Expect to change once for every 20 days, while clear up the excrement of larva, reduce the growth of germ etc..Aseptically to enter during operation
OK, including fold up the tweezers of feed, the cutter of cutting carrot is intended to ensure that cleaning is clean.As find to have insect infection or it is dead will and
When connect bottle removal, and the processing that carried out disinfection to the climate box.
(3)Timing sterilization.Due to the often switch climate box such as observing or operating, easily pathogenic bacteria in air and will
Acarid is brought into vessel, therefore every 20 days, climate box is sterilized, the dilute solution of 84 thimerosals may be selected in thimerosal(Dilution 20
Times).
Embodiment two
(One)Method:
The observation discriminating conduct of 1.1 female, male moths
Huge furuncle bat chrysalis is taken, is put under stereoscope, observes the morphological feature of abdomen end, and numbering of taking pictures.It is different by form, will
Pupa is divided into different type.Sprout wings to pupa, according to the sex of emerging adult, retrodict the sex for confirming pupa.
Pupa is directly placed into sky tissue culture bottle, or prepares 2.5% agar(Containing 0.4% preservative)Mixture pours into tissue culture
Bottle, then pupa is put into bottle, it is capped ventilating cover;Before treating that pupa is sprouted wings, when body colour becomes dark brown, pupa is moved into empty tissue culture bottle, under pupa
Pad puts clean filter paper, and the upward side wrinkle of filter paper get up to supply the adult of emergence to seek connections with.Relative humidity 80 ± 2%, temperature 19~22
℃。
1.2 seek a spouse mating condition:Male and female each one or female two hero are pressed by the firm emergence of single head raising, with age in days adult
Breeding observing is mated, ensures all virgin moths.Worm cage is divided into three types:Type A, top is gauze, periphery has three faces to be
Gauze, it is simultaneously plastic sheeting, in the imago cage for inside there are bottled fresh host plant smalt branches and leaves, is stopped for adult suspension, be living
Move, seek a spouse and mate and oviposit;Type B, worm cage and type A are same, but do not have smalt branches and leaves;Type C, worm cage top portion are plastic sheeting
Or glass, surrounding are gauze.Temperature conditionss are 23~25 DEG C, and relative humidity is 80 ± 2%, photoperiod 12L:12D.Using
Night infrared video camera(Lay coloured silk HD-A210)Shooting records the mating behavior at its night, the female male worm mating whole story of record each pair
Time and the number of mating, altogether 30 cage.
(Two)As a result with analysis
The identification of 2.1 female, male pupas
The diagnostic characteristics of female, male pupa:Female pupa is shown in accompanying drawing 1, Fig. 3, and one article of middle cross band that the 7th uromere outside of belly is made up of furcella is wavy
Bending is obvious, followed by the smooth " V " shape striped in a centre, is connected to the central black longitudinal crevasse of the 8th uromere outside of belly;Lobe
Seam both sides send " eight " shape line, the black burr clump in the outside of connection two.Longitudinal crevasse both sides are flat, no projection, between being stitched with anal fissure
Distance be noticeably greater than male pupa.
Male pupa is shown in accompanying drawing 2, Fig. 4, and one article of wavy middle cross band bending of the 7th uromere outside of belly is obvious, thereafter have a black
The straight cross band of burr;8th uromere center free from flaw, two outside lefts similar to female respectively have one clump of black burr;9th uromere
There is a black longitudinal crevasse in center rearward, and respectively there is an ovate strumae on both sides;Longitudinal crevasse and anal fissure seam distance are near.
2.2 mating behavior results
As a result finding, type A worm cages, top is gauze, and adds fresh-keeping smalt branches and leaves, adult mating success rate highest,
Up to 60.12%;And type B worm cage, top are gauze, smalt branches and leaves, adult mating success rate only up to 35.29% are not added with;Class
Type C worm cages, top are plastic sheeting or glass, and adult fails mating.
