Problems solved by technology

[0006] Planting plants and cultivating seedlings is a time-consuming and laborious work, and the cost is high;
[0007] The depth of the octagonal bottle is too deep, it is inconvenient to change food, absorb thrips, etc., and it is easy to accumulate water vapor, resulting in moldy beans and death of nymphs

Abstract

The invention belongs to the technical field of insect breeding, and particularly discloses a frankliniella occidentalis population number expanding propagation method. The method comprises the following steps of laying a piece of kitchen paper at the bottom of an insect breeding box, putting fresh four-season pods on the kitchen paper, inoculating adult frankliniella occidentalis, sucking out theadult frankliniella occidentalis in the insect breeding box after 2-3 days, and putting the sucked adult frankliniella occidentalis into a new insect breeding box containing fresh four-season pods tocontinue to lay eggs; and covering the egg-laying insect breeding box with an insect breeding box cover, putting the egg-laying insect breeding box into an incubator for incubating, carrying out observing for 5 days, discarding the four-season pods when all larvae are incubated, and putting fresh four-season pods as food of the larvae into the incubator. According to the method, the age of the frankliniella occidentalis in each insect breeding box is basically consistent, the relatively high survival rate and eclosion rate of pupae are guaranteed, and a high-quality insect source is providedfor later insecticide screening research.

Description

technical field [0001] The invention belongs to the technical field of breeding insects, and in particular relates to a method for multiplying populations of western flower thrips. Background technique [0002] Western flower thrips Frankliniella occidentalis, also known as alfalfa thrips (English name: Western Flower Thrip), belongs to Thysanoptera (Thripidae) flower thrips (Frankliniella), is the most important in the world in the 1970s and 1980s. One of the most invasive horticultural and agricultural pests. Western flower thrips is native to North America, and is now distributed in about 57 countries on all continents of the world, including America, Europe, Asia, Africa, and Oceania. my country first discovered Thrips occidentalis in Beijing in July 2003, and has established stable populations in Beijing, Yunnan, Zhejiang, Shandong and other provinces and cities. Western flower thrips has the characteristics of small size, fast reproduction, strong infectivity, and wi...
