Feeding device for fruit tree pest mites and using method

Abstract

The invention provides a feeding device for fruit tree pest mites and a using method. The feeding device comprises a fixing device, an inoculation device, a supporting device and a shed cover, whereinthe fixing device comprises two semicircular tiles and two one-loop helixes, the lower portions of the two semicircular tiles are integrally softly connected, and the upper portions on the outer sidefaces of the semicircular tiles are fixedly connected with the one-loop helixes; the inoculation device comprises an installation plate, folding arms, a mite receiving plate and a folding line rod; the bottom of the installation plate is provided with the folding line rod, a threaded hole is formed in the center of the installation plate, the folding arms are hinged to the left portion and the right portion of the installation plate, the middle on the bottom face of the mite receiving plate is fixedly connected with a screw rod, and the screw rod is matched with the threaded hole in the installation plate; the positioning supporting device comprises at least one folding line rod, and the upper ends of the folding line rods are provided with positioning balls. The device and the using method thereof can be used in different growth cycles of spider mites, the feeding survival rate is high, and the stability of experimental mite sources can be ensured to the greatest extent.

Description

technical field [0001] The invention belongs to the field of plant protection, and in particular relates to a breeding device and a using method for fruit tree pest mites. Background technique [0002] Hawthorn spider mite, also known as hawthorn spider mite, has a body length of about 0.5 mm, dark red in summer type and bright red in winter type, belonging to the order Acarina and Tetranychidae. It is an important harmful mite that commonly occurs on deciduous fruit trees in my country. The mite causes adult mites and nymphs to gather on the back of the leaf and suck it. The damaged leaves appear small chlorotic spots, which then expand into flakes. In severe cases, the back of the leaf turns brown, or even Burnt off. The mite reproduces quickly, has many generations, and is extremely harmful. [0003] Therefore, hawthorn spider mite is the key experimental object of plant protection workers. In order to ensure the stability of the experimental insect source, the staff oft...

Problems solved by technology

[0003] Therefore, hawthorn spider mite is the key experimental object of plant protection workers. In order to ensure the stability of the experimental insect source, the staff often need to artificially raise hawthorn spider mite. Now there is no special equipment for the cultivation of hawthorn spider mite, and the breeding survival rate is low. Great environmental impact
