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 wheat moth eggs and other insects such as beet armyworm eggs and armyworm eggs, such as the industrial production of Trichogramma technology from wheat moth eggs, the patent number is ZL02129344.9, the Trichogramma rice borer The artificial breeding production method, application number CN201410354251.X and the artificial breeding production method using a kind of Trichogramma rice borer, application number CN201611118429.6, but it is difficult to popularize and apply in production due to various conditions

Embodiment 1

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

[0026] 1. Snowy Moth Egg

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

[0028] 1.2 For the rearing of pre-3rd instar larvae, put the soon-to-hatch eggs of the snow moth into an insect culture dish covered with feed, and cover it with a toilet paper pad to prevent the small larvae from escaping. On the second day, after all the larvae hatched, the worm-raising dish was inverted; 100 larvae were placed in each worm-raising dish;

[0029] Transfer the larvae at the end of the third instar to the rearing box for three-dimensional rearing; first fill the feed grid 5 with feed and insert it into the breeding box, transfer the 3rd instar larvae to the rearing box, and the larvae will crawl to the grid 5 to feed Feed and excrete feces; feces leak into the feces box 4 through the feces filter screen 3, and the feces are cleaned up every day until the end of...

Embodiment 2

[0041] Production of corn borer Trichogramma to control corn borer.

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

[0043] 2. Production of Trichogramma corn borer

[0044] 2.1 Pick up bees in the dark room, put the prepared Trichogramma bee species and fresh eggs in the ratio of 1:20~25 in the dark room for inoculation and parasitism, and remove the bee species after 48 hours;

[0045] 2.2 Development and culture, transfer the parasitized egg card or egg grain to the development room for 3-4 days to develop to the pre-pupation stage, and then move it into the cold storage for storage;

[0046] 2.3 Heating development, according to the bee release time, 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 and put them into the bee release device;

[0047] 2.4 Release in the field, put about 600 eggs (including about 2,000 Trichogramma...

Embodiment 3

[0049] Controlling Sugarcane Borer by Producing Trichogramma

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

[0051] 2. Production of Trichogramma

[0052] 2.1 Pick up bees in the dark room, put the prepared Trichogramma bee species and fresh eggs in a ratio of 1:25~30 in the dark room for inoculation and parasitism, and remove the bee species after 48 hours;

[0053] 2.2 Development and culture, transfer the parasitized egg card or egg grain to the development room for 3-4 days to develop to the pre-pupation stage, and then move it into the cold storage for storage;

[0054] 2.3 Heating development, according to the bee release time, 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 and put them into the bee release device;

[0055] 2.4 Release in the field, put about 600 eggs (including about 2,000 Trichogrammas) of the parasitic ...

Abstract

The invention discloses a method for breeding Trichogramma by using the egg of the snow moth as a host, and discloses a new insect egg suitable for industrial production of various Trichogrammas. Compared with the existing bee breeding technology, it has the advantages of breeding It has many advantages such as many species, high reproductive efficiency and low cost. The method of the invention is easy to raise, and artificial feed can be raised; the fecundity is high, and the amount of eggs laid by a single moth is about 600-1000; the eggs are large, and the diameter of the eggs is about 0.7mm, and a single egg can breed 3-4 heads of Trichogramma; The generation cycle is short, and it takes about 50 days from egg to adult; the egg mass is large and easy to separate, and the egg is laid in a single piece, easy to collect; the egg shell is thick, convenient for bee picking, packaging and transportation, and the activity of Trichogramma parasitism is extremely strong And many other advantages, with greater advantages and broad 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...
