Preparation method of blocky feed for mealworm larvae and method for culturing and putting wheat moth cocoons

Abstract

The invention provides a preparation method of blocky feed for mealworm larvae. The preparation method comprises the following steps 1, weighing raw materials; 2, preparing a mixture; and 3, preparinga spherical blocky material with the diameter of 40-80mm to obtain the blocky feed for the aleurodes punctiferalis larvae. The blocky feed prepared by the method can be used for realizing centralizedcollection of a large amount of the aleurodes punctiferalis larvae; The invention also provides a method for culturing and putting wheat moth cocoons. The method comprises the following steps A, preparing the culture device, the mesh bag, the aleurodes punctiferalis larva blocky feed and the aleurodes punctiferalis eggs; B, placing a mesh bag in the culture device, placing blocky feed and mealworm eggs in the mesh bag, and then conducting culturing; C, after 14-16 days, obtaining a mesh bag filled with the aleurodes punctiferalis larvae; D, placing the mesh bag in a wheat moth cocoon bee hive, and after 60-72 h, obtaining a mesh bag containing wheat moth cocoon bee eggs; and E, the mesh bag continues to remain in the beehive for expanding propagation; or within 14 days after parasitism iscompleted, the mesh bag is taken out to be used for releasing the Cotesia vesuviana. The method can quickly and efficiently realize the culturing and putting application of the wheat moth cocoons.

Description

technical field [0001] The invention relates to the technical field of biological control of agricultural pests, in particular to a method for cultivating and releasing Braconidus larvae with larvae of Trichomonas moth as a host, and a feed for cultivating larvae of Trichomonas moth. Background technique [0002] The Chinese patent with the application number 201910489252.8 discloses a method for mass-feeding the larvae of Braconus cerevisiae to kill the stored tobacco mealworm. , and introduce the paired 1st-generation Braconidus adult bees into the first breeding box; after the 1st-generation Braconis parasitizes the host larvae to lay eggs, obtain the eggs of the 2nd generation Braconus; S2, wait for S1 After the eggs of the 2nd-generation Braconis cerevisiae grow into larvae and pupate, the pupae are transferred from the first rearing box to the transport box for loading, and the temperature in the transport environment where the transport box is located is 12- 18°C; S3...

AI Technical Summary

Problems solved by technology

[0003] There is a very big difficulty in the existing method of raising and applying the Braconidia spp.: because the culture feed of the host larvae of the existing Brassia spp., that is, the mealybug larvae, is powdery feed, the larvae of the mealybug are very easy to Drilling into the powdered feed and forming a net, the netting will cause the powdered feed to agglomerate. Therefore, when collecting the mealybug larvae, it is necessary to pour out the powdered feed from the cultivation device. The agglomerated powdered feed needs to be Only by breaking up can the larvae be taken out, so that the collection of the mealybug larvae needs a lot of time, manpower and material resources, and the dust in the collection process is relatively large, which is not conducive to the health of the staff, and has also seriously affected the expansion of the larvae. Breeding and cultivating hinders the mass production of Braconis cerevisiae

[0004] In addition, in the existing method of raising and applying the Braconis cerevisiae, the larvae larvae pupae on the body of the host larvae are forcibly removed, and then the pupae are stored at low temperature and transported. , After low-temperature transportation, the survival rate will inevitably decrease, and the adaptability to the prevention and control environment will deviate, and the cost of this transportation method is too high
