A kind of Helicoverpa armigera nuclear polyhedrosis virus self-propagation device and method

Abstract

Disclosed are a self-spreading device and method for helicoverpa armigera nuclear polyhedrosis viruses. The device comprises a reflective cover, a powder storage mechanism and an inhabiting platform arranged at the bottom of the powder storage mechanism; the powder storage mechanism comprises an inner cylinder body and an outer cylinder body in threaded connection with the inner cylinder, the inner cylinder body is internally provided with a first cavity body, the lower end of the inner cylinder body is provided with a first opening communicated with the first cavity body, the outer cylinder body is internally provided with a second cavity body, the top of the outer cylinder body is provided with a second opening for the inner cylinder body to extend into the second cavity body, the bottomof the outer cylinder body is provided with a bottom plate, and the outer side face of the lower end of the outer cylinder body is provided with at least one powder outlet; the inner cylinder body isinternally provided with a sex attractant. An insect virus powdery agent is stored in the powder storage mechanism and flows out of the external inhabiting platform through the powder outlets in theouter cylinder body. Insects are attracted by light or pheromones to move around the spreading device and can utilize the inhabiting platform to inhabit and carry the insect viruses on the inhabitingplatform to enter the environment when they leave, and the insect viruses are spread.

Description

technical field [0001] The invention relates to the field of microbial control of pests, in particular to a self-propagating device and method for nuclear polyhedrosis virus of cotton bollworm. Background technique [0002] In the microbial control of pests, the behavior of insects is often used to spread microorganisms, so as to control pests. For example, Chinese Patent Publication No. 106942177 is a pest trapping device, preparation method and application, wherein the device includes a hard colored insect trapping board, a fungus tape that can infect pests, a suspension with an attractant and a slow-release agent , the hard colored insect-attracting board is folded into a box with openings at the left and right ends, and the fungus band with the infested pests is placed on the bottom of the inner wall of the box; the box with the attractant and slow-release The suspension of the agent is hung on the top of the inner wall of the box, which has the advantage of using the i...
