Multifunctional tephritidae natural enemy sanctuary, and preparation method and use method thereof

Abstract

The invention discloses a multifunctional tephritidae natural enemy sanctuary, which comprises a main body structure and a frame, wherein the main body structure comprises a rain blocking surface, parasitic wasp entering and leaving surfaces, transition surfaces and pressing edges; the frame comprises three-way pipes, metal pipes and pipe covers; the rain blocking surface is arranged on the top ofthe main body structure; the side surfaces of the rain blocking surface are independently provided with the parasitic wasp entering and leaving surface; the lower part of each parasitic wasp enteringand leaving surface is provided with the transition surface; and the lower part of each transition surface is provided with the pressing edge. By use of the multifunctional tephritidae natural enemysanctuary, the field population establishment capability and the utilization efficiency of the tephritidae parasitic wasp can be improved, the multifunctional tephritidae natural enemy sanctuary can be used for the field trapping and protection of the parasitic wasp by aiming at varied requirement functions in different types of tephritidae prevention and treatment, the field population establishment capability of the parasitic wasp can be improved, and the multifunctional tephritidae natural enemy sanctuary can be auxiliarily used for trapping and killing tephritidae adults.

Description

technical field

[0001] The invention relates to the field of fruit fly control, in particular to a multifunctional natural enemy fruit fly shelter and its preparation and use methods. Background technique

[0002] Tephritid pests are economically important Diptera insects that are widely distributed in tropical, subtropical and temperate regions of the world. Due to its wide range of hosts, strong flying ability and reproductive ability of adults, borer damage inside the fruit, and easy long-distance spread with the damaged melons and fruits, it poses a huge threat to the healthy development of the fruit and vegetable industry. Taking Guangdong Province as an example, only three species of fruit flies, Bactroceradorsalis, Zeugodacus cucurbitae, and Z. tau, cause a total economic loss of about 3.367 billion to 12.997 billion yuan per year to the social economy of Guangdong Province. The efficient use of parasitoids is one of the important auxiliary means to control fruit fly...
