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

Embodiment 1

[0036] refer to Figure 2 to Figure 4 , a release device for natural enemies of parasitic wasps, which includes a cup body 1 and an outer cover 2, the cup body 1 is a conical shell, the big end of the cup body 1 has a cup mouth 10, and the inner diameter of the big end of the cup body 1 is 12cm, the inner diameter of the small end of the cup body 1 is 8cm, the cup body 1 is high 18cm, and the edge of the outer cover 2 is suitable for the cup mouth 10 limits of the cup body 1. The cup body 1 of the present invention can also be manufactured with reference to the production process and dimensions of disposable plastic cups or disposable paper cups during production. The size of the cup body 1 can be held with one hand or both hands as well.

[0037] There are several natural enemy release holes 20 on the outer cover 2, the diameter of the natural enemy release holes 20 is 5mm, and the middle part of the outer cover 2 has an outer cover perforation.

[0038] Cup body 1 is also p...

Embodiment 2

[0043] Use the natural enemy release device of embodiment 1 to realize the parasitic wasp class natural enemy sustained release method, it comprises the following steps:

[0044] In step 1, a number of stored-grain moth larvae and adult parasitic wasps of the first 2nd instar and above are placed in a culture environment for parasitism, and after 1 day, the stored-grain moth larvae in the culture environment are taken out as hosts.

[0045] Step 2, select the parasitic wasp natural enemy release device of embodiment 1, the edge of the outer cover 2 is connected with the cup mouth 10 sides of the cup body 1, and the operating tube 4 is moved through the rubber ring 42 so that it is positioned and connected to the outer cover 2 and made The edge of the inner cover 3 is clamped on the inner wall of the lower position of the cup body 1 (the diameter of the inner cover 3 is larger than the diameter of the small end of the cup body 1 during design, so that the distance between the sn...

Embodiment 3

[0050] refer to Image 6 with Figure 7 , the difference between the present embodiment and embodiment 2 is that the structure of the parasitic wasp natural enemy release device used is different, specifically: in the parasitic wasp natural enemy release device selected by this embodiment, the ring flange 31 side of the inner cover 3 has a ring Groove, described annular groove is filled with pheromone attractant 7, and pheromone attractant 7 is generally paste or solid, when parasitic wasp natural enemy release device is in the state of natural enemy (such as Image 6 shown), the pheromone attractant 7 is blocked between the inner cover 3 and the inner wall of the cup body 1 to avoid failure, when the natural enemy is continuously released (such as Figure 7 shown), the pheromone attractant 7 takes effect, and has a strong luring effect on moth pests, causing a large number of moth adults to fly into the cup body 1, providing enough fresh hosts for parasitic wasps, and improv...

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...
