Embodiment 1

[0038] Plant broad bean seedlings with planting pots and vermiculite in the laboratory, cut off the broad bean seedlings when they grow to 10-15cm, and let them dry in a ventilated environment for 15-20 minutes to dry the liquid at the cutting edge of the plant, then place the broad bean seedlings in clean water for a while. Cultivate a spare.

[0039] Put the egg-laying medium of the newly produced stinkbug eggs downward and the eggs face up, and collect the newly produced stinkbug eggs into a 12cm sterilized petri dish with wet filter paper built in the petri dish, and place the petri dish containing the stinkbug eggs on the Temperature 26 ± 1 ℃, 65 ± 5% RH, 16:8 (L: D) conditions of artificial climate box culture, add distilled water to the petri dish every day until the stink bug eggs hatch; transfer the newly hatched stink bug nymphs to 300ml Add an appropriate amount of distilled water to the cotton on the wet absorbent cotton block of the hard plastic aviation cup every...

Embodiment 2

[0041] Plant pea seedlings with planting pots and vermiculite in the laboratory. Cut off the pea seedlings when they grow to 10-15cm, and let them dry in a ventilated environment for 15-20 minutes. Cultivate a spare.

[0042] Collect the newly laid stinkbug eggs into a 12cm sterilized petri dish, with the egg-laying medium facing down and the egg surface facing up, with wet filter paper built into the petri dish, and placing the petri dish containing the stinkbug eggs at a temperature of 26±1°C. 65 ± 5% RH, 16:8 (L: D) conditions of artificial climate box culture, add distilled water to the petri dish every day until the stinkbug eggs hatch; transfer the newly hatched stinkbug nymphs to the 300ml hard plastic aviation cup Add appropriate amount of distilled water to the cotton every day on the wet absorbent cotton block, until the gnat stink molt reaches 2 instars. Wrap the base of pea shoots (PS) (groups of 2-3 roots) with wet absorbent cotton to prevent the host plant from ...

Abstract

The invention relates to a method for improving the raising effect of arma chinensis by adding substitute host plants. According to the method, pea seedlings or broad bean seedlings are adopted as thehost plants for raising arma chinensis. The method comprises the following steps that the host plants are added into a raising space, and the arma chinensis is inoculated. In the method, host plants(such as poplar or elm branches and leaves) used in a traditional arma chinensis raising process are replaced with the broad bean seedlings or the pea seedlings which are easier to obtain, a host plant cultivation method in the raising process is improved, and the service life of the host plants is effectively prolonged. The method is easy to operate, the difficulty of obtaining the host plants for predatory natural enemy insect arma chinensis adults is greatly reduced, the arma chinensis raising effect is improved, and the method has an important significance in large-scale propagation and field release of the natural enemy insect, namely arma chinensis.

Description

technical field [0001] The invention belongs to the technical field of insects, and in particular relates to a method for improving the breeding effect of gnat bugs by adding alternative host plants. Background technique [0002] The stink bug can prey on eggs, larvae and adults of more than 40 kinds of agricultural and forestry pests. It also has a good control effect on invasive pests such as potato beetle, American white moth, and fall armyworm. It is an important local natural enemy insect. With the enhancement of people's awareness of environmental protection, the method of using natural enemy insects to control agricultural and forestry pests has gradually been paid attention to by people. [0003] For a long time, people have added poplar, elm branches and soybean seedlings as host plants in the breeding process of stinkbugs to increase the range of activities of stinkbugs, reduce the self-mutilation of stinkbugs, and increase the acquisition rate of stinkbug adults. ...
