Novel method for collecting rice moth imago

Abstract

The invention relates to a novel method for collecting rice moth imagoes, which is characterized by comprising the following steps of: lengthways arranging rice moth feeding discs in an eclosion device, so as to enable rice moths to become moth imagoes through eclosion; before a imago is collected, charging CO2 gas for 3-5 minutes, so that the rice moth imago stifles to lose consciousness within a short time, and automatically falls into a rice moth collecting device at the bottom of a box body, intensively collecting to put in a spawning cage, wherein the imago can wake up after 1 minutes, withdrawing the rice moth feeding discs from the box type eclosion device till that the eclosion finishes, and stopping collecting the batch of imagoes. According to the method, adverse factors of the conventional collecting method, such as low rice moth collecting efficiency, complex operation, and imago injury can be overcome, the collection of a large batch of imagoes can be realized, and the requirement of factory production can be met.

Description

technical field [0001] The invention relates to a new method for collecting rice moth adults, in particular to a method for collecting rice moth adults in the industrial production process of intermediate hosts (rice moth eggs) for the reproduction of Trichogramma, which belongs to the field of agricultural technology biological pest control technology. Background technique [0002] The rice moth belongs to Lepidoptera and Mellophilidae. It is a kind of storage pest, which mainly harms rice, paddy and various storage materials. As a high-quality feed for raising lacewings and an excellent host for breeding Trichogramma, rice moth eggs have played an important role in the field of biological control in my country. [0003] At present, the industrial production of Trichogramma in my country is mainly based on tussah silkworm eggs as the host, and the breeding species are limited to Trichogramma pine caterpillar and Trichogramma borer. Trichogramma, rice borer Trichogramma, et...

AI Technical Summary

Problems solved by technology

However, a large-scale production line for propagating Trichogramma using rice moth eggs as host eggs has not yet been established. The main reason is that the adult collection technology has not yet been resolved.

In the industrial production of rice moth, the crucial link is the collection technology of rice moth adults. At present, most of the moths in the laboratory are collected in test tubes, which is not only laborious and laborious, but also has a low yield.

Though also have the invention of rice moth collecting machine, as " a kind of environment-friendly type rice moth adult moth collecting machine ", the patent application number is 201010265859.7, compared with artificial shock or capture, efficiency has improved to a certain extent, but it can only Suitable for small area production or for laboratory research
