Problems solved by technology

After the natural enemy insects are reared indoors for multiple generations, they often have shortened lifespan, decreased egg production, and decreased egg weight, which are not conducive to their growth and reproduction.
The shortened lifespan of adults will greatly affect the total number of predatory pests after they are released, and also affect their egg production. How to prolong the lifespan of adult gnats has become a problem worthy of attention in the breeding process of gnats

Embodiment 1

[0035] A method for prolonging the lifespan of adult stinkbugs, comprising the following steps: 1) putting 3 to 5 grams of newly produced stinkbug eggs into a 50ml centrifuge tube; 2) adding untreated stinkbug eggs to the centrifuge tube in step 1) After sterilizing the eggs with deionized water, put the centrifuge tube into the shaker for three times of shaking, each time shaking at a speed of 700-800rpm for 15s, and let the centrifuge tube stand for 3 minutes between two adjacent shaking treatments; then centrifuge Suck out the sterilized deionized water in the tube; then add a volume concentration of 75% ethanol solution submerged in the stinkbug eggs to the centrifuge tube, put the centrifuge tube into the oscillator for 15s, and shake at a speed of 700-800rpm. After standing still for 4min, the ethanol solution in the centrifuge tube was subsequently sucked out; 3) after the stinkbug ovum obtained in step 2) was rinsed with sterilized deionized water, the stinkbug ovum was...

Embodiment 2

[0037] A method for prolonging the lifespan of adult stinkbugs, comprising the following steps: 1) putting 3 to 5 grams of newly produced stinkbug eggs into a 50ml centrifuge tube; 2) adding untreated stinkbug eggs to the centrifuge tube in step 1) After sterilizing the eggs with deionized water, put the centrifuge tube into the oscillator for four shock treatments, each time at a speed of 700-800rpm for 15s, and let the centrifuge tube stand for 3 minutes between two adjacent shock treatments; Suck out the sterilized deionized water in the centrifuge tube; 3) Rinse the stinkbug ovum obtained in step 2) with sterilized deionized water, then place the stink bug ovum on sterilized filter paper to absorb the surface moisture ; 4) Place the stinkbug eggs obtained in step 3) evenly in a 12cm sterilized culture dish, set the temperature of the culture environment to be 25-27°C, the humidity to be 60-70%, and the photoperiod to be 16L:6D; The sterilized filter paper sprayed with ster...

Abstract

The invention relates to a method for prolonging life of adult arma chinensis. The method includes following steps: 1), putting newly-generated arma chinensis eggs into a centrifugal tube; 2), addingsterilized deionized water into the centrifugal tube in the step 1), and putting the centrifugal tube into an oscillator for at least three times of oscillation treatment; 3), adding sterilized deionized water into the centrifugal tube in the step 2), and putting the centrifugal tube into the oscillator for oscillation treatment; 4), adding sterilized deionized water into the centrifugal tube in the step 4), and putting the centrifugal tube into the oscillator for oscillation treatment; 5), using sterilized deionized water to flush and clean the arma chinensis eggs obtained in the step 4), andusing sterilized filter paper to blot up water on the surface. After arma chinensis eggs treated through the above experiment steps are hatched to form adults, life of the adults is obviously prolonged in lab conventional feeding conditions, so that improving of propagation of arma chinensis population is facilitated, and economic cost, time cost and labor cost of arma chinensis feeding are saved.

Description

technical field [0001] The invention relates to the field of artificial breeding of insects, in particular to a method for prolonging the lifespan of adult gnat bugs. Background technique [0002] The long-term use of chemical pesticides seriously threatens my country's food and ecological security, and also greatly affects the national health. Here, the prevention and control of crop pests is particularly important. At present, biological control centered on the use of natural enemy insects can effectively control the number of pests and reduce the use of pesticides. Doing a good job in the indoor propagation of natural enemy insects is the primary task when it is applied to pest control. The stinkbug belongs to the Hemiptera stinkbug family. It is a natural enemy insect with a wide range of predation. It can prey on the larvae or adults of more than 40 kinds of agricultural and forestry pests such as leaf beetles, cotton bollworms, silver-leafed moths, slug moths, scarabs...
