Embodiment

[0025] refer to figure 1 , the present embodiment provides a kind of batch-feeding method for the adult bees of Braconis cerevisiae to kill storage tobacco mealworm, comprising the following steps:

[0026] S1. Put the host larvae of Braconidus cerevisiae into the first breeding box, and introduce the paired 1st generation of Braconis cerevisiae adults into the first breeding box; add concentration of 10-70 to the first breeding box every day. % bee sugar water; and place the first breeding box in an environment with a temperature of 27-29°C, a relative humidity of 70-80% and a photoperiod of 16L; wait until the first generation of Braconis parasitizes and lays eggs on the host larvae. Get the 2nd generation Braconidus;

[0027] S2. After the eggs of the 2nd generation of Braconis cerevisiae in S1 finally emerge into adult bees through eggs, larvae, and pupae, transfer the second rearing box to an environment with a temperature of 4°C until the adult bees are anesthetized by ...

Embodiment 2

[0038] Simultaneously, the present invention also proposes a feed for artificially raising the larvae of the tobacco mealworm;

[0039] Before formulating the feed, dry corn sand and half-broken wheat in an oven (60°C) for 1-3 hours to obtain the total weight of the formulated feed, make three groups of experiments A, B, and C for comparison, and weigh the components of each component according to the corresponding proportion. Weight (see Table 1), and weigh the solid first, then the liquid, after weighing all the materials, stir them evenly;

[0041]

[0042]

[0043] According to the growth and reproduction result of raising the tobacco powder borer at last, the artificial feed evaluation analysis of the present invention is as follows:

[0044] (1) Development period:

[0045] There was no significant difference in the egg stage, larval stage and pupal stage of the tobacco powder borer fed with the three ...

Abstract

The invention discloses a method of killing warehouse Ephestia elutella by cultivating adults of Habrobracon hebetor in batch and belongs to the technical field of warehouse prevention and treatment of pyralid moth pests. The method comprises the steps of S1, introducing host larvae of Habrobracon hebetor and first-generation adults of Habrobracon hebetor into a first rearing box, with suitable ambient conditions ensured and nutrients added regularly; S2, after second-generation eggs of Habrobracon hebetor in S1 grow into adults via egg-larva-moth process, transferring a second rearing box tothe ambient temperature of 2-6 DEG C until the adults are anaesthetized and immobilized by cold; transferring the adults of Habrobracon hebetor from the first rearing box to a transport box for truckloading; and S3, transporting the transport box into a warehouse with tobacco, transferring the adults of Habrobracon hebetor from the transport box into a release device; after larvae of Habrobraconhebetor occur on tobacco bales, opening the release device to release the larvae, so that the adults of Habrobracon hebetor may parasitically kill Ephestia elutella on the warehouse tobacco.

Description

technical field [0001] The invention relates to the technical field of storage prevention and control of borer moth pests, in particular to a method for killing stored tobacco powder borers by raising adult bees in batches. Background technique [0002] Tobacco powder borer larvae mainly feed on tobacco leaf mesophyll, and leave a lot of tobacco leaf debris and brown insect droppings on the tobacco leaves after eating, which further causes the damaged tobacco leaves to be easily moldy and deteriorated. According to domestic investigations and studies, tobacco powder borer Together with other storage pests, my country loses about 31.15 million kg of tobacco leaves every year. At present, the control of tobacco powder borer is mainly through the use of pyrethroid insecticides as chemical means, and the setting of trap lights as a means to kill tobacco powder borer adults. However, it is difficult for both methods to kill and control the larvae of the tobacco mealworm; although t...
