Device and method for self-propagation of beet armyworm nuclear polyhedrosis virus

Abstract

The invention provides a self-propagation device and method of nuclear polyhedrosis viruses of beet armyworm. The self-propagation device comprises a reflection lampshade, a powder storage mechanism and an inhabitation platform which is arranged on the bottom of the powder storage mechanism. The powder storage mechanism comprises an inner cylinder and an outer cylinder which is in threaded connection with the inner cylinder, a first cavity is formed in the inner cylinder, a first opening communicated with the first cavity is formed in the lower end of the inner cylinder, a second cavity is formed in the outer cylinder, and a second opening allowing the inner cylinder to stretch into the second cavity is formed in the top of the outer cylinder. A bottom plate is arranged on the bottom of the outer cylinder, and one or more powder outlets are formed in the outer side face at the lower end of the outer cylinder; a sex attractant is arranged in the inner cylinder. Insect virus powder is stored into the powder storage mechanism, and flows out of the powder outlet in the outer cylinder to the inhabitation platform. When lured by light or pheromones to carry out activities on the propagation device, insects can inhabit on the inhabitation platform, and after leaving off, the insects can carry insect viruses on the inhabitation platform and enter an environment, so that propagation ofthe insect viruses is achieved.

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 beet armyworm nuclear polyhedrosis virus. 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 insect...

Problems solved by technology

However, the structure of the device is simple, and it can only be used for spreading and killing insects with fungal belts, and cannot be applied to the spread of other insect microorganisms.
