A kind of feeding method of Chilo borer

Abstract

The present invention relates to the technical field of insect feeding, in particular to a feeding method of Chilo suppressalis. The eggs are placed at the intersection of the leaf sheath and the main stem of the first rice stalk, and the hatched larvae drill into the first rice stem from the intersection. The stalks are fed; when the larvae develop to the 5th instar, the larvae are taken out from the first rice stalk and raised on the second rice stalk; The fresh rice stalks at the culm jointing stage or after the round culm jointing stage; the second rice stalks are knotted round culm jointing stages or fresh rice stalks after the round culm jointing stage. The raising method of the rice stem borer of the invention has the advantages of high survival rate of larvae and pupae, convenient finding of pupae, suitable for research, and large-scale breeding.

Description

technical field [0001] The invention relates to the technical field of insect feeding, in particular to a feeding method for Chilo suppressalis. Background technique [0002] Chiloborer belongs to Lepidoptera, Boreridae, and is one of the most serious frequent pests on rice in my country. It eats rice stems, damages rice at the tillering stage, and causes dead sheaths and seedlings; damages booting and heading. rice at the early stage, causing dry booting and white ears; damage to rice at the filling and milk maturity stages, causing half-dead ears and insect-damaged plants. The damaged plants are clustered and distributed in the field, with an obvious center. In addition to harming rice, Chilo borer can also harm weeds such as water bamboo, corn, sorghum, sugar cane, rape, broad bean, wheat, reed, barnyardgrass, and Lishihe. In order to facilitate the research on C. borer, it is usually necessary to raise C. borer artificially. [0003] The prior art, such as the Chinese ...

AI Technical Summary

Problems solved by technology

[0003] The prior art, such as the Chinese patent document CN204599047U, discloses a device for efficiently raising the stem borer. The host plant used to raise the stem borer is rice seedlings or rice stems that are easy to rot and deteriorate or become moldy. Careful observation is required during the raising process. The condition of the host plant, if it is found to be rotten or moldy, it needs to be replaced in time, and the rottenness or moldiness of the plant may be part of it, sometimes it is difficult to observe, if the larvae eat the host plant, it will lead to malnutrition of the larvae , Infected with germs and died, therefore, the mortality rate of larvae is high

Moreover, the larvae bite the pupae, which will lead to high pupae mortality and a significant decrease in the number of effective pupae, seriously affecting the eclosion of adults and bringing difficulties to the raising of the next generation.

Larvae become pupae and are distributed in glass bottles, which makes it time-consuming to find and peel pupae during feeding, and is not suitable for large-scale subculture

In the prior art, there is also a method of raising C. borer with artificial feed. The biological characteristics of C. conduct research that may lead to inaccurate research results
