Parasitic wasp natural enemy release device and parasitic wasp natural enemy sustained release method

Abstract

The invention discloses a parasitic wasp natural enemy release device which comprises a cup body and an outer cover; particularly, natural enemy release holes are formed in the outer cover; an inner cover with air holes is arranged in the cup body; the bottom end of an operating pipe is fixedly connected with the inner cover; the upper end of the operating pipe penetrates through the outer cover, and the operating pipe is closed by an operating cover; a rubber ring sleeves the upper end of the operating pipe for positioning. The device is simple in structure and convenient to use. The invention further provides a parasitic wasp natural enemy sustained release method which comprises the following steps: (1) allowing parasitic wasps to parasitize stored-grain moth larvae, and serving the parasitized stored-grain moth larvae as hosts; (2) connecting the outer cover with the cup body to ensure that the inner cover is clamped on the inner wall of the cup body, putting the hosts in the cup body through the operating pipe, and closing the operating cover to enable the device to be a natural enemy storage device; (3) within 15 days since wasp receiving, pulling up the operating pipe to ensure that a wasp outlet passage is formed in the cup body, carrying out positioning through the rubber ring, putting fodder into the cup body through the operating pipe, and closing the operating pipe, so that the device can be placed in a control area for biological control. Through adoption of the device and the method, parasitic wasp natural enemies can be sustainably released to the control area to achieve long-term and effective biological control.

Description

technical field [0001] The invention belongs to the technical field of pest control, and in particular relates to a device and method for biological control of natural enemies of parasitoid bees. Background technique [0002] The Chinese patent with application number 201210074834.8 proposes a parasitic natural enemy insect release device and a sustainable release method. There is a net partition in the middle of the net, and the diameter of the hole on the net partition and the net cover is between the diameter of the natural enemy and the main body of the intermediate host. The natural enemy can pass through after eclosion, and the unparasitized intermediate host is isolated after eclosion. The steps of using the release device to realize the continuous release of natural enemies are: 1. Arrange some release points in the prevention and control area and install a release device; Before eclosion, place an appropriate amount of unparasitized fresh hosts on one side of the n...

AI Technical Summary

Problems solved by technology

The disadvantages of this natural enemy continuous release method are: 1. New hosts need to be added manually, and the cultivation and selection of new hosts also need to invest in manpower, which has the disadvantages of large manpower input and high cost; The host organisms in the tube are isolated from the outside world, but it is absolutely impossible to completely isolate the host organisms. Adding fresh hosts to the release tube will inevitably cause unparasitized hosts to escape to the outside world after eclosion, increasing The number of pests in the control area will increase the burden of control, so it is necessary to improve
