Device for preventing feed mildewing in frankliniella occidentalis feeding process and use method

Abstract

The invention relates to a device for preventing feed mildewing in the frankliniella occidentalis feeding process and a use method. The device comprises a groove-type box body (1) with an open top, and a handle (5) is arranged on the outer side wall of the box body (1); fine sand (3) is laid in the box body (1), filter paper (4) is laid on the fine sand (3), and a green beam frame (2) is arrangedon the filter paper (4). The device has the advantages of being easy to operate, reasonable in design and capable of saving manual labor force and improving the breeding efficiency, in the process ofstudying the frankliniella occidentalis control problem in our country, a large number of indoor populations can be propagated rapidly for a laboratory to use, and the device can be applied and popularized in all research institutes and colleges and universities.

Description

technical field [0001] The invention belongs to the technical field of insect rearing, and in particular relates to the technical field of a device structure and a use method for preventing feed: green beans from becoming moldy during the feeding process of western flower thrips. Background technique [0002] Western flower thrips [Frankliniella occidentalis (Pergande)] is an important worldwide vegetable, flower and other horticultural plant pests belonging to the genus Thysanoptera. It can cause rust-brown spots on leaves and fruits, making the fruits commercial. Loss, in addition to direct damage to host plants, may also spread tomato spotted wilt virus and impatiens necrotic spot virus. The research on the prevention and control of western flower thrips has always been the direction that experts at home and abroad are still working on. The occurrence of western flower thrips is large, and the damage time is long. It is aimed at the serious occurrence and safety preventio...

AI Technical Summary

Problems solved by technology

[0003] In the indoor experiment of Western flower thrips, it is necessary to raise a large number of Western flower thrips populations. Kidney beans, as a common feed for western flower thrips indoor breeding, have the characteristics of cheap price, simple planting, and easy acquisition. In the prior art, for Western flower thrips uses green beans to raise and place green beans to be moldy. There are still few methods, and green beans often become moldy during indoor breeding, which seriously affects the survival of western flower thrips, and the replacement of feed is too cumbersome, making thrips Escape, the green beans can’t be kept for a different time, and the nymphs of the thrips are lost, causing a large number of thrips to escape and die, making it difficult to breed a large population of thrips indoors

At present, green beans are used to breed western flower thrips, which not only increases the labor cost and labor load in the breeding process, but also requires greater labor intensity and time consumption in the operation process, and cannot effectively and rapidly multiply a large number of western flower thrips population, reducing thrips feeding efficiency
