Embodiment 1

[0019] Feeding steps:

[0020] Step (1), preparing materials: cutting the stems from mature Chinese cabbage for subsequent use, and the length of the Chinese cabbage stems is 10 centimeters;

[0021] Step (2), collecting ovum: collecting the first egg and blackhead stage egg mass on the rape branch, placing the first egg mass branch in a container filled with water, changing the water at least once a day until the egg develops into the blackhead stage, Then cut the egg mass branches at the blackhead stage into small sections, with no more than 7 eggs on each section;

[0022] Step (3), ovum inoculation: connect the ovum branch at the blackhead stage to the stem described in step (1), and the number of ovum inoculation is no more than 20;

[0023] Step (4), cultivating: place the stem described in step (3) in a transparent airtight container capable of moisturizing, and then place it in a light incubator for cultivation, the cultivation temperature is 18°C, the relative humidi...

Abstract

The invention relates to the technical field of agricultural insect breeding, in particular to a method for breeding Evergestis extimalis Scopoli larvae indoors. The method includes the steps of 1, material preparation, wherein a 10 cm stem core is sheared for use; 2, egg collecting, wherein primary eggs and egg clusters in the black head period are collected on an oilseed rape branch for use; 3, egg grafting, wherein the branch with the egg clusters in the black head period is grafted to the stem obtained in the step 1, wherein the number of grafted eggs is not larger than 20; 4, culture, wherein the stem obtained in the step 3 is put into a transparent closed container capable of preserving moisture and then put into a light culture box to be cultured with the culture temperature being 18-25 DEG C, the relative humidity being 50-70% and the photoperiod L:D being 14:10 till 2-3-age larvae are obtained. The method has the advantages that influences on growth and development of Evergestis extimalis Scopoli larvae are avoided, the process is simple, operation is convenient, and the survival rate of larvae is high; the method has practical significance in scientific research application.

Description

technical field [0001] The invention relates to the technical field of raising agricultural insects, in particular to a method for raising fennel larvae indoors. Background technique [0002] Fennel thin-winged wild borer (Evergestisextimalis Scopli), belongs to Lepidoptera (Lepidoptera, Pyralidida). Also known as rape horn borer, fennel borer, and rape borer, it is mainly distributed in northern regions such as Qinghai, Gansu, Ningxia, Inner Mongolia, and Heilongjiang in China, and distributed in North Korea, Japan, the United States, and Northwest Asia abroad. It mainly harms fennel, beet, cabbage, rape, shepherd's purse, radish, cabbage, mustard and other plants. At present, this insect is an important and destructive pest in spring rapeseed fields in Qinghai Province. It mainly damages spring rapeseed by larvae drilling pods and eating seeds, and its damage range continues to expand, seriously threatening the production of spring rapeseed in Qinghai. . [0003] For th...
