Technology for industrially culturing trichogramma with gelechiid ova

A technology of wheat moth eggs and trichogramma, which is applied in animal husbandry and other directions, can solve the problem that the uniformity of egg laying and the number of bees per unit space cannot be improved, and the collection rate of wheat moth eggs cannot be improved. Low cleanliness and other problems, to achieve the effect of making full use of personnel, broadening the application of Trichogramma species, and improving the efficiency of feeding work

Problems solved by technology

[0002] In the prior art, the production and reproduction of Trichogramma in my country mainly use large eggs as intermediate hosts, and its disadvantage is that the effect of preventing farmland pests is low and the application range is narrow
In recent years, there is also a process of using small eggs as intermediate hosts, such as the patent application with the patent publication number of CN1253723A, but the selected feed is too affected by the change of environmental temperature and humidity; adding water after the feed is disinfected will easily cause secondary pollution; it is impossible to achieve one-time inoculation The collection rate and cleanliness of wheat moth eggs are low due to multiple generations of harvesting moths; due to the structure of the multi-generation beehive, the uniformity of egg spreading and the number of multi-bees per unit space cannot be improved, and the quality of multi-bees is low

Embodiment Construction

[0013] Further illustrate below in conjunction with embodiment:

[0014] A kind of industrial production Trichogramma process with wheat moth eggs, comprising the following process: select 135g of barley with husks as feed, and put the feed (barley) into a feed frame (wooden with stainless steel mesh on both sides) after washing and removing impurities. Frame) heated to 100°C in a high-temperature disinfection cabinet, kept for 60 minutes, and then took out the barley to cool naturally and dry for one day, and the water content of the barley was 15%. The sterilized barley is divided into 3 batches (50kg per batch, with an interval of 1 week) and packed into feed boxes at a rate of 2.5kg per box. Into the larval rearing room for cultivation. After 3 weeks of inoculation, the feed with worms was transferred to the adult feeding box and transferred to the adult collection box to prepare for collecting adults. Each adult feeding box can hold 7.5kg feed, and a single adult collec...

Abstract

A technology for reproducing trichogramma with gelechiid ova in industrial mode incldues light-shielding vertical raising, automatical collection of mothes, removing dust and impurities and continuous reproduction.

Description

Technical field [0001] The present invention relates to a technology for cultivating Trichogramma, in particular to a technology for industrial production of Trichogramma using wheat moth eggs, and belongs to the technical field of biological control of agricultural pests. Background technique [0002] In the existing technology, the production and reproduction of Trichogramma in my country mainly uses large eggs as intermediate hosts. Its shortcomings are low effectiveness in preventing farmland pests and narrow application range. In recent years, there has also been a process of using small eggs as intermediate hosts, such as the patent application with patent publication number CN1253723A. However, the selected feed is greatly affected by changes in environmental temperature and humidity; adding water after disinfection of the feed can easily cause secondary pollution; and it is impossible to achieve one-time inoculation. When harvesting moths fo...
