Description

A feeding device for fruit fly pupal parasitoids

technical field

The utility model relates to the technical field of parasitoid bee breeding, in particular to a breeding device for parasitoid wasps in fruit fly pupae.

Background technique

Pupal parasitoids are the key to the biological control of fruit fly pests. Large-scale propagation is the primary condition for their field application, and a simple and labor-saving insect rearing device is a necessary material to complete the large-scale propagation of parasitoids. Existing rearing devices designed for fruit fly pupal parasitoids mainly adopt the following types: the first type, containers such as petri dishes and finger tubes, which are simple and easy to obtain, but are extremely inconvenient when changing hosts, raising and collecting. And the workload is heavy, and it is only suitable for small-scale indoor experiments; the second type, mesh or glass insect cages, this type of device is more suitable for large-scale propagation, and it is relatively simple to exchange food for parasitic bees, but the cost is relatively high. It is not easy to change hosts for parasitic bees and collect parasitic bees; the third type is the insect culture box with complex design, including nutritional supplement area, parasitic area and activity area for parasitic bees. It is relatively simple to exchange food and receive bees, but it is not easy to replace hosts and collect parasitic bees. Therefore, need a kind of improved fruit fly pupa parasitoid rearing device badly to overcome above-mentioned defective.

Chinese Patent Publication No. CN201777577U discloses a transfer bottle loaded with Vespa. Its structure is a transparent bottle body made of polyethylene material, a bottle cap is provided at the bottle mouth, and several bottle cap holes are provided on the top surface of the bottle cap. Diameter is the round hole of 3mm, and the bottom of the bottle is also provided with several diameters of the bottle bottom holes of 3mm, and the bottle cap and the bottle mouth are screwed together. The bottle is loaded with wasps for long-distance transportation, which is safe and convenient. The inner wall of the bottle is smooth and can be transferred to another container very conveniently. It will not cause damage to the living wasps and affect its feeding and utilization effect. But this operation bottle bottle mouth setting is relatively small, it is very inconvenient when needing to collect parasitic wasps, need to put nutrient and parasitic bees together when using, has reduced the survival rate of parasitoids.

Therefore, need badly a kind of improved parasitoid rearing device to overcome above-mentioned defective.
