Embodiment 1

[0037] A method for increasing the amount of eggs laid by stinkbugs, comprising the following steps: 1) putting 3 to 5 grams of newly produced stinkbug eggs into a 50ml centrifuge tube; After the volume concentration of stinkbug eggs is 75% ethanol solution, put the centrifuge tube into the shaker for three shock treatments, each time at a speed of 700-800rpm for 15 seconds, and let the centrifuge tube stand for 3 minutes between two adjacent shock treatments Then the ethanol solution in the centrifuge tube is sucked out; 3) after adding the centrifuge tube in step 2) to the centrifuge tube that has not crossed the stink bug ovum, the volume concentration is 4% formaldehyde solution, the centrifuge tube is put into the oscillator and carried out 15s, and the rotating speed is Shock treatment at 700-800rpm, after standing for 4 minutes, then suck out the formaldehyde solution in the centrifuge tube; 4) add an ethanol solution with a volume concentration of 75% that has not passe...

Abstract

The invention relates to a method for increasing the egg laying amount of arma chinensis. The method comprises the following steps that 1) newly laid arma chinensis eggs are placed in a centrifuge tube; 2) after an ethanol solution is added into the centrifuge tube in step 1), and the centrifuge tube is placed in an oscillator for three-time oscillation treatment; 3) after a formaldehyde solutionis added into the centrifuge tube in step 2), the centrifuge tube is placed in the oscillator for oscillation treatment; 4) after the ethanol solution is added into the centrifuge tube in step 3), thecentrifuge tube is placed in the oscillator for oscillation treatment; 5) after the obtained arma chinensis eggs in step 4) are rinsed thoroughly with a sterilized deionized water, the surface moisture is sucked dry with sterilization filter paper. The method for increasing the egg laying amount of arma chinensis has the advantages that after the arma chinensis eggs treated through the experimental steps are hatched into adult arma chinensis, under the conventional breeding conditions of a laboratory, the egg laying amount is effectively increased, thereby being conductive to the expanding propagation of arma chinensis population, and saving the economics, time and labor cost of arma chinensis raising.

Description

technical field [0001] The invention relates to the field of artificial breeding of insects, in particular to a method for increasing the egg-laying capacity of stinkbugs. 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, sc...
