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 parasites 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

[0031] refer to Figure 2 to Figure 4 , a parasitic wasp natural enemy releasing cup, which includes a cup body 1, and the top of the cup body 1 has a cup mouth 10.

[0032] The cup body 1 is equipped with a breathable cup cover 2 and a natural enemy release cover 3, the edges of the breathable cup cover 2 and the natural enemy release cover 3 are adapted to the cup mouth 10 sides of the cup body 1, and the breathable cup cover 2 has several Air vent 20, the diameter of air vent 20 is 0.5mm, has several natural enemy release holes 30 on the natural enemy release cover 3, and the diameter of natural enemy release hole 30 is 5mm.

[0033] During production, the cup body 1 of the present invention can be manufactured with reference to the production process and dimensions of disposable plastic cups or disposable paper cups, and the size of the cup body 1 can be held with one or both hands.

[0034] The cup body 1 is covered with a ventilating cup cover 2 and becomes a natural en...

Embodiment 2

[0037] The method for sustained release of parasitic wasp natural enemies realized using the natural enemy release cup of embodiment 1 comprises the following steps:

[0038] Step 1, placing a number of stored grain moth larvae and parasitic wasp adults of the first 2 instars and above in a culture environment for parasitism, and the stored grain moths can be stored grain moth insects such as wheat moth, rice moth, and Indian grain moth , the parasitic wasp is a stored grain parasitic wasp such as Braconis spp., Adenia spp., etc. After 1 day, take out the stored grain moth larvae in the cultivation environment as the host;

[0039] Step 2, in the cup body 1 of the parasitic wasp natural enemy release cup of the present embodiment 1, put a number of hosts in step 1, and the number of hosts in each cup body 1 can be tiled on the cup body 1 with all the hosts Limit on the bottom surface, the mouth of a cup 10 of the cup body 1 is sealed with the breathable cup cover 2, so that it...

Embodiment 3

[0044] refer to Image 6 The difference between this embodiment and embodiment 2 is that: apply an appropriate amount of glue on the inner wall of the cup body 1 of the natural enemy sustained release cup 12 in step 3 and paste the pheromone attractant 6, which is generally a paste Or solid, the pheromone attractant 6 has a strong luring effect on moth pests, so that a large number of moth adults fly into the cup body 1, providing enough fresh hosts for parasitic wasps, and improving the effect of the present invention for continuously releasing parasitic wasps.

Abstract

The invention discloses a parasitic wasp type natural enemy releasing cup. Specifically, the cup body comprises a ventilated cup cover provided with ventilating holes and a natural enemy releasing cover provided with natural enemy releasing holes, and columns or straight columns provided with holes are arranged at the natural enemy releasing holes in the natural enemy releasing cover. The parasitic wasp type natural enemy releasing cup is simple in structure, is easy to produce and is convenient to use. The invention further discloses a parasitic wasp type natural enemy continuous releasing method. The method comprises following steps: 1) employing second and more instar stored-grain moth larvae which are parasitized by parasitic wasps as hosts; 2) placing multiple hosts in the cup body of the natural enemy releasing cup, and covering the cup mouth of the cup body by the use of the ventilated cup cover so as to form a natural enemy storage cup; and 3) within 15 days since the parasitic wasps parasitize the larvae, opening the natural enemy storage cup and adding feed into the natural enemy storage cup, covering the cup body by the use of the natural enemy releasing cover so as to form a natural enemy continuous releasing cup, placing the cup in a prevention and control region, and further adding pheromone attractant into the natural enemy continuous releasing cup. According to the invention, parasitic wasp type natural enemies can be continuously released to the prevention and control region, so that effective biological prevention and control can be achieved for a long period.

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...
