Problems solved by technology

However, because the time from the egg to the hatching of the larvae is only 7 days, and the multiplication period is short, the eggs cannot be stored for a long time and cannot be used in a timely manner, which has become a technical bottleneck restricting the large-scale production and application of the stinkbug.

Embodiment Construction

[0014] The present invention is a cold storage diapause method for stinkbug, the method comprising:

[0015] (1) Select the eggs of the stink bug as the object of diapause in cold storage.

[0016] (2) Place the eggs of the stink bug selected in the step (1) in a cold storage diapause environment, the temperature of the cold storage diapause is 2-6° C., and the time of the cold storage diapause is 8-12 days.

[0017] Preferably, the temperature of cold storage diapause is 4°C, and the time of cold storage diapause is 10 days.

[0018] Preferably, the armyworm eggs that have just been laid by the stinkbug are selected as the cold storage diapause object. Compared with the armyworm eggs that have been laid for a certain period of time, the cold storage diapause effect of the fresh armyworm eggs is better.

[0019] Preferably, the relative humidity of the refrigerated diapause is 60±10%, which is a suitable storage temperature for the stink bug eggs, and higher or lower temperat...

Abstract

The invention discloses an arma chinensis cold storage diapause method. The method comprises the following steps that (1) arma chinensis armyworm eggs are selected as cold storage diapause objects; and (2) the arma chinensis armyworm eggs selected in the step (1) are placed in a cold storage diapause environment, wherein the cold storage diapause temperature is 2-6 DEG C, and the cold storage diapause time is 8-12 days. Aiming at arma chinensis which is an excellent predatory natural enemy insect, the control research of regulating and controlling the arma chinensis armyworm egg incubation time by utilizing factors such as cold storage temperature and time is carried out, the research finds that the incubation rate of the arma chinensis armyworm eggs still reaches 50% or above after the arma chinensis armyworm eggs stand for 6-14 days in the cold storage diapause environment with the temperature of 0-8 DEG C, and large-scale cultivation requirements can be basically met.

Description

technical field [0001] The invention relates to a diapause method for stinkbugs in cold storage, and belongs to the technical field of stinkbug breeding. Background technique [0002] The stink bug is a natural enemy insect with a wide range of predation. It can prey on more than forty kinds of common agricultural and forestry pests such as pine caterpillars, inchworms, leaf beetles, sting moths, scale insects, aphids, cabbage caterpillars, etc. In terms of controlling the number of pest populations Have a significant effect. The use of gnat bugs in biological control can greatly reduce the use of pesticides in the field and in the greenhouse, protect the ecological environment, and ensure food and food safety. [0003] The biological characteristics of stink bugs are: adults like to crawl, but are not good at flying, and they live in the shade of forests in summer to prey on various insects. When the temperature is 25-30°C and the relative humidity is about 70%, the adult...
