Description

A kind of Moringa Nao snout moth's larva method for breeding using man-made feeds
Technical field
The invention belongs to technical field of insect feeding, specifically a kind of Moringa Nao snout moth's larva raising side using man-made feeds Method.
Background technique
Moringa complete stool various pieces can develop and use and widely used, such as ornamental, eat, medicinal, for planting Purification and the ideal oilseed plant of object oil and beer, nectariferous plant, herding material and yule logs.Moringa Nao snout moth's larva (Noorda Blitealis it is) newfound a kind of Microlepidoptera pest on China's Moringa, is mainly caused harm with larval feeding blade, harm is tight It can be by Moringa blade eat everything up when weight.Existing Moringa Nao snout moth's larva distribution is saved in Yunnan Province of China at present, in some Moringa gardens Population outbreak, and have the tendency that gradually extending, seriously threaten Moringa production.For safe prevention Moringa Nao snout moth's larva, should reinforce pair The biology and Study of Prevention Technology of Moringa Nao snout moth's larva, this just needs artificial feeding Moringa Nao snout moth's larva, establishes stable indoor population, solution Certainly test the supply problem of worm sources.
Once there were the report with fresh Moringa blade raising Moringa Nao snout moth's larva in foreign countries, but there are distinct disadvantages for this method: peppery The wooden blade holding time is short, and humidity is then easy to rot greatly, and humidity is low to be then easy to dry up, and influences Moringa Nao snout moth's larva larval feeding; In addition, Moringa Nao snout moth's larva larva is very big in gluttony phase appetite, largely it must feed and clear up daily using the raising of fresh Moringa blade, consume Take a large amount of manpower and material resources.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of Moringa Nao snout moth's larva raising using man-made feeds Method, to use manpower and material resources sparingly, solve selected insect source supply problem, it is established that the Moringa Nao snout moth's larva method for breeding of indoor population.
The method of the present invention is as follows:
1,3 more than age healthy Moringa Nao snout moth's larva larvas are collected from field, 29~31 DEG C, relative humidity 70% ± 10%, Under conditions of illumination L:D=14 ︰ 10, raised with man-made feeds to pupating;
2, healthy person is put into dependent insect cage in step gained Moringa Nao snout moth's larva pupa in selection, in 29~31 DEG C, relative humidity 70% Under conditions of ± 10% shading save, be put into after adult eclosion, in cage weight concentration be 4.5~5.5% hydromel at Worm supplements the nutrients;
3, under conditions of 29~31 DEG C, relative humidity 70% ± 10% and shading, by adult obtained by upper step according to male and female Quantity is placed in the bottle of gauze sealing than the ratio for 1:2, be put into bottle hydromel that weight concentration is 4.5~5.5% at Worm supplements the nutrients, and bottle bottom places oviposition paper, lays eggs for female adult, checks oviposition situation, after 2~3 days, pieces of an egg blackening daily After can carry out next step raising;
4, under conditions of 29~31 DEG C, relative humidity 70% ± 10%, illumination L:D=14 ︰ 10, by the ovum of upper step blackening Block is placed in the bottle equipped with fresh Moringa blade and is sealed with gauze, culture 6~12 hours i.e. visible larvae hatch, ovum and new Fresh Moringa blade quantity ratio is that every ovum places 1~2 blade;
5, the larva access that 1~2 age in days of upper step hatches is placed in the breathable sealing glass container of man-made feeds, often The feed of replacement in 3~4 days, until larvae pupation, the feed relative being put into every time is 2~3 times of Weight of larvae;
6, continuously rearing: repeat according to above 2 to 5 step;
The formula of described man-made feeds are as follows: Moringa 99~101g of leaf dried powder, 9~11g of agar, 4.5~5.5g of yeast powder, first 0.095~1.05ml of aldehyde, 0.45~0.55g of sorbic acid, 0.38~0.42g of ascorbic acid, 19~21mg of glucosinolates, water The particle that diameter is 0.4~0.6cm is made in 500ml after mixing.
Man-made feeds can be prepared as follows:
Load weighted Moringa leaf dried powder and yeast powder are first added to the cold water of formula total Water 3/5, stir evenly be made into it is outstanding Supernatant liquid, it is spare;
Load weighted agar powder is poured into pot again, the water of formula total Water 2/5 is added, be heated to boiling and constantly uses glass The stirring of glass stick;
Sorbic acid is added under fluidized state, mixes thoroughly, stops heating, formaldehyde is added, agar solution is made;
The suspension is poured into the agar solution cool to 60~65 DEG C, adds load weighted ascorbic acid powder, It stirs evenly cooled and solidified and obtains man-made feeds.
It is an advantage of the invention that man-made feeds are easy to save, low in cost, the palatability of Moringa Nao snout moth's larva is good, polypide development Normally, make it possible that high density concentrates raising Moringa Nao snout moth's larva, provide experiment worm sources to stablize.
Specific embodiment
See following embodiment:
Larva goes through the phase 8~11 days, and pupa time 5~9 days, the adult stage 5~7 days, specific steps are as follows:

From the healthy larva more than age of field acquisition Moringa Nao snout moth's larva 3, in 30 DEG C, relative humidity 70% ± 10%, illumination item Under conditions of part L:D=14 ︰ 10, raised with man-made feeds to pupating.
(2) preservation of pupa and adult eclosion
The Moringa Nao snout moth's larva pupa of health is collected and is put into dependent insect cage, in 30 DEG C, the item of relative humidity 70% ± 10% Shading saves under part, is put into the hydromel that weight concentration is 5% after adult eclosion, in cage for Adult supplement nutrient.
(3) preservation of Adult worms producting eggs and ovum
Under conditions of 30 DEG C, relative humidity 70% ± 10% under dark conditions, adult is the number of 1:2 according to sex ration Amount, is placed in oblate glass candy bottle, bottleneck is sealed with gauze, prevents adult from escaping.It is 5% that weight concentration is put into bottle Hydromel for Adult supplement nutrient appearance, bottle bottom place two by commercially available 80g printing paper fan-folded (radius 10.5cm, wide 2cm) oviposition paper, for female adult oviposition.Daily regular check oviposition situation, and the paper of replacement oviposition in time.
Daily with a batch of ovum, can be put together at one, after 2~3 days, pieces of an egg be slightly variable it is black after can be transferred to can In bottle.
(4) raising and transfer of larva
Under conditions of 30 DEG C, relative humidity 70% ± 10%, 10 ︰ illumination condition L:D=14, the pieces of an egg of blackening are placed It in the can equipped with fresh Moringa blade (bore 7cm, high 10cm), and is sealed with gauze, prevents larva from escaping.Every bottle puts 80 ovum are set, ovum and fresh Moringa blade quantity ratio are that every ovum places 2 blades;Cultivate 8 hours visible larvae hatch;
1~2 day old larva is gently accessed in the finger-type pipe for being placed with man-made feeds with writing brush (bore 2cm, high 7cm), and It is sealed with tampon.Every pipe places 5 larvas, 3 feeds.The feed of replacement in every 3 days, until larvae pupation.It is put into every time Feed relative is 2 times of Weight of larvae.
(5) continuously rearing
Repeat according to the step of (2) to (4).
The formula of man-made feeds used are as follows: Moringa leaf dried powder 100g, agar 10g, yeast powder 5g, formaldehyde 1ml, sorbic acid The particle of diameter 0.5cm is made in 5g, ascorbic acid 0.4g, glucosinolates 20mg, water 500ml after mixing.
Man-made feeds are prepared as follows:
Load weighted Moringa leaf dried powder and yeast powder are first added to the cold water of formula total Water 3/5, stir evenly be made into it is outstanding Supernatant liquid, it is spare;
Load weighted agar powder is poured into pot again, the water of formula total Water 2/5 is added, be heated to boiling and constantly uses glass The stirring of glass stick;
Sorbic acid is added under fluidized state, mixes thoroughly, stops heating, formaldehyde is added, agar solution is made;
The suspension is poured into the agar solution cool to 65 DEG C, adds load weighted ascorbic acid powder, is stirred Uniform cooled and solidified obtains man-made feeds.
