Problems solved by technology

However, due to the long development period of the rice moth, the reproduction multiple of the existing feeding method is up to about 100 times, and the Trichogramma bred by the rice moth eggs is not resistant to long-term storage, which requires that it needs to be stored in a short period of time. Produce a large number of rice moth eggs for the parasitism of Trichogramma, causing certain pressure on production space and production costs
At the same time, there are also bee breeding technologies based on

Example Embodiment

[0024] Example 1

[0025] Production of rice borer Trichogramma to control rice stem borer

[0026] 1. Eggs of snow moth

[0027] 1.1 Breeding of snow moth, temperature 26±1℃, relative humidity 65%;

[0028] 1.2 Feeding of pre-third instar larvae, put the eggs of the snow moth that are about to hatch into a petri dish covered with feed, and cover with toilet paper pads to prevent small larvae from escaping. On the 2nd day, after all the larvae hatch, turn the pesto upside down; put 100 larvae in each pestle;

[0029] Transfer the 3rd instar larvae to the rearing box for three-dimensional rearing; first fill the feed grid 5 with feed and insert it into the rearing box, transfer the 3rd instar larvae to the rearing box, and the larvae will crawl on the grid 5 to feed on their own Feed and excrete the feces; the feces leak through the fecal filter 3 into the feces container 4, clean the feces every day until the end of the larvae's end of feeding, remove the fecal filter 3, and make the ...

[0040] Example 2

[0041] Produce corn borer Trichogramma to control corn borer.

[0042] 1. The production of white snow moth eggs is the same as implementation case 1.

[0043] 2. Production of corn borer Trichogramma

[0044] 2.1 Receiving bees in a dark room, put the prepared Trichogramma corn borer seed and fresh eggs into a bee receiving box or canned bottle at a ratio of 1:20-25 in full darkness for parasitism, and remove the bee seed 48 hours later;

[0045] 2.2 Developmental culture, transfer the parasitic egg card or egg pellet to the developmental room for 3-4 days to the pre-pupa stage, and then move it to the cold storage for storage;

[0046] 2.3 Heating development, according to the time of placing the bees, take out the refrigerated parasitic eggs in advance, heat them in the development room until the bees emerge quickly, and then make cards or loose eggs into the bee placing device;

[0047] 2.4 For field release, about 600 eggs of snow moth parasitized with Trichogramma...

[0050] 1. The production of the eggs of the snow moth is the same as the implementation case 1;

[0051] 2. Production of Trichogramma yellow borer

[0052] 2.1 Receiving bees in a dark room, put the prepared Trichogramma sylvatica bee species and fresh eggs in a ratio of 1:25 to 30 in the bee receiving box or canned bottle for parasitic inoculation, and remove the bee species after 48 hours;

[0053] 2.2 Developmental culture, transfer the parasitic egg card or egg pellet to the developmental room for 3-4 days to the pre-pupa stage, and then move it to the cold storage for storage;

[0054] 2.3 Heating development, according to the time of placing the bees, take out the refrigerated parasitic eggs in advance, heat them in the development room until the bees emerge quickly, and then make cards or loose eggs into the bee placing device;

Abstract

The invention discloses a method of breeding trichogrammas with spilosoma menthastris, and discloses a new insect egg applicable to industrialized production of multiple trichogrammas. According to the method, feeding is simple, and artificial feed can be applied to feeding; the reproductive capacity is high, and the egg laying amount per spilosoma menthastri is 600-1000; eggs are big, the dimeterof the eggs is about 0.7 mm, and each egg can breed 3-4 trichogrammas; the generation cycle is short, and about 50 days are needed from eggs to imagoes; egg blocks are big and easy to separate, and the eggs are separated grains and are easy to collect; egg shells are thick, trichogramma receiving, packaging and transportation are convenient, and the activity of the trichogrammas after the trichogrammas are parasitic is extremely high. Compared with the prior trichogramma breeding art, the method of breeding the trichogrammas with the spilosoma menthastris has the large, extensive advantages of being multiple in breeding variety, high in breeding efficiency, low in cost and the like, and has a wide market demand.

Description

technical field [0001] The invention relates to a method for propagating Trichogramma by using the eggs of the snow moth moth as a host, discloses new insect eggs suitable for industrial production of various Trichogrammas, and belongs to the technical field of biological control of agricultural pests. Background technique [0002] Trichogramma is the most widely used egg-parasitic natural enemy insect in the world. Trichogramma spends the rest of the period except adult bees in the host eggs. Therefore, obtaining suitable host eggs is the key to the industrial breeding of Trichogramma. An intermediate host suitable for industrial production should have the following characteristics: 1) insect eggs can be parasitized by this species of Trichogramma, and they like to parasitize; 2) After laying eggs, the offspring of Trichogramma can be successfully completed in the host egg. Development and emergence of bees; 3) The nutrition of the host egg liquid can meet the developmenta...
