Device suitable for propagation of tephritidae-type insects and propagation method of device

Abstract

The invention relates to a device suitable for propagation of tephritidae-type insects and a propagation method of the device. The device comprises a cultivation chamber, a pupating chamber and a ventilation lid; the cultivation chamber and the pupating chamber are both utensils with upper ends opened; the cultivation chamber is formed in the pupating chamber, and the ventilation lid is arranged at the top of the pupating chamber; a dry sand layer is laid at the inner bottom of the pupating chamber, the cultivation chamber is formed in the portion above the dry sand layer, the ventilation lidis in fastened or threaded connection with the pupating chamber, and a ventilation gauze net is arranged in the middle of the ventilation lid; the cultivation chamber is internally provided with an artificial feed layer and a natural feed layer, the artificial feed layer is arranged at the inner bottom of the cultivation chamber, the natural feed layer is arranged on the artificial feed layer, andmoisture-retention gauze is laid on the upper portion of the natural feed layer. The device has the advantages that the device is easy to manufacture, practical and reusable; by means of the method,the survival rate and the pupating rate of tephritidae-type larvae are high and reach 90% or above; by means of the device, the contamination of other indoor and outdoor insects, particularly fruit flies can be avoided, and purification of obtained tephritidae pupae and imagoes is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of an insect breeding device and a breeding method using the device; in particular, it belongs to the technical field of a device specially used for the breeding of fruit fly insects and a breeding method using the device. Background technique [0002] The species of Tephritidae (Tephritidae), collectively referred to as fruit flies (Fruit fly), are important agricultural pests, among which the species that harm melons and fruits are the main ones, and their larvae are all latent feeding, parasitic in the fruit body and harming all parts of plants. , from roots, stems, leaves, flowers and even fruits, resulting in fruit rot, fruit drop, or even failure to harvest, posing a serious threat to the yield of fruit trees. At the same time, because the larvae hide in the fruit and feed on it, it is difficult to check it out from the appearance of the fruit in the quarantine at the import checkpoint. Therefore, in ...

Problems solved by technology

[0003] The previous laboratory breeding methods included directly placing melon pieces inoculated with fruit fly eggs on sandy soil, or using pots and the like as pupation vessels. Disadvantages such as contamination by indoor and outdoor fruit flies; more importantly, once the larvae feed is mixed with fruit fly larvae, the fruit fly larvae will basically all die
