Bionic trapping device and trapping method for living frankliniella occidentalis

Abstract

The invention relates to a bionic trapping device for living frankliniella occidentalis. The device comprises a trapping cover (1), a trapping base (2) connected with the trapping cover (1) in a cooperative mode, a peripheral gauze screen (3) fixedly arranged on an opening of the trapping cover (1) and a central gauze screen (4) arranged in the center of the peripheral gauze screen (3); the exterior of the peripheral gauze screen (3) is provided with brackets (5) supporting the screens; the corresponding end of the opening of the trapping cover (1) is fixedly provided with a sleeve ring (6) connected with the trapping base (2) in a cooperative mode; the upper portion of the trapping base (2) is provided with a filament-imitated structure (7) with inverted hooks. The bionic trapping device is simple in structure, convenient to use, low in cost and high in flexibility, the labor efficiency can be significantly improved, the labor intensity is reduced, and the quantity of living frankliniella occidentalis trapped in the wild field is increased. A trapping method for living frankliniella occidentalis ensures the efficiency of agricultural production to the maximum degree with the purposes of achieving minimal resource consumption, most environment-friendly and fastest trapping and highest trapping number.

Description

technical field [0001] The invention belongs to the technical field of insect trapping device structure and trapping method, and specifically refers to the technical field of live trapping device and trapping method specially used for insects such as 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. [0003] When doing research on Thrips occidentalis in the laboratory, it is often necessary to collect in the wild first, and then multiply to ...

Problems solved by technology

[0004] In the prior art, most of the collection of western flower thrips can only collect dead thrips, and it is difficult to guarantee its survival. The number of traps increased, and a variety of compounds have been found to have this effect, but all of the trapped western flower thrips died, and part of the trapping also used the two single methods of western flower thrips on color and smell separately, and Devices and methods for trapping live Western flower thrips have been poorly studied

The live collection of Western flower thrips mainly adopts the disc method, or directly picks the flowers for collection. However, because the individual of western flower thrips is only between 1 and 2 mm and has a certain flying ability, the disc method is easy to cause thrips. A large number of horses escape, and it is easy to collect more impurities (such as: pollen, filaments, dry leaves) and other insects when collecting western flower thrips at the same time, which affects the efficiency of the experiment

And adopting the method of picking flowers has destroyed gathering plants in essence, if directly gathering flowers such as roses, pomegranates etc. in gathering shed will certainly cause loss, and can not guarantee the western flower thrips quantity in the flowers, the collected There are few male thrips western flowers, and the males are a population that often needs a lot of research in the research process; moreover, the two methods are cumbersome to operate, the number of collection is small, and other impurities and insects are greatly affected, and the operation process requires a lot labor intensity and time consumption
