Field colonization method for searching natural enemy arma chinensis

Abstract

The invention provides a field colonization method for searching a natural enemy arma chinensis. The field colonization method for searching the natural enemy arma chinensis comprises the following steps of S1, uniformly coating fluorescent paint on a pronotary and tegmina of the natural enemy arma chinensis by using a banister brush, putting the arma chinensis into an insect breeding cage, and taking the natural enemy arma chinensis to the field for releasing after the fluorescent paint is dried; and S2, irradiating from the releasing position by using a fluorescent flashlight at night after releasing, searching the arma chinensis, and investigating the diffusion amount of the arma chinensis and the field distribution condition of the arma chinensis. The fluorescent paint is evenly coated on the pronotary and the tegmina of the natural enemy arma chinensis, the arma chinensis is released in the daytime, then the fluorescent flashlight is used for irradiating and searching the arma chinensis from the releasing position at night, and the released arma chinensis can be found conveniently; after the fluorescent paint is used for marking, the diffusion condition of 60% or above of target insects can be investigated, the tracking effect is improved by four times or above, the tracking effect is improved, the effect is good, operation is easy, and efficiency is high.

Description

Technical field [0001] The present invention belongs to the technical field entomological research, and more particularly, relates particularly to a method for colonization of wild predators searching of Arma chinensis. Background technique [0002] Arma chinensis is a very strong natural enemies of insect predation, prey in the field can be 40 kinds of pests on agriculture and forestry, has great potential applications in the field of biological prevention and control. But after the release of Arma chinensis currently on the spread of the field is still blank, Arma chinensis released into the field, occasionally set perched on a plant leaf surface, but a pair of prey in crops or weeds. In order to assess the situation predators Arma chinensis colonization in the field, we need to understand its diffusion and distribution in the field, but on the human eye search of Arma chinensis is difficult to find in the field, and currently has the notation (paint mark, colored marker, was b...

Problems solved by technology

However, there is still no information about the spread of the stinkbug after it is released into the field. After the stinkbug is released into the field, it occasionally lives on the surface of plant leaves, but preys on crops or weeds

In order to evaluate the colonization of the natural enemy, the stinkbug in the field, it is necessary to understand its diffusion and distribution in the field, and it is difficult to find the stinkbug in the field by searching with the naked eye, and the current marking methods (paint marking, marker pen coloring, attachment method, internal standard method) can not achieve the purpose of the experiment, existing in vitro marking methods such as marker pen coloring mark, paint mark, due to the concealment of insect diffusion, the amount of target insects can be observed after smearing Only around 15%, comparable to that observed without markers

Colored attachment mark: the insect body is too small, the attachments affect its normal diffusion, and the research purpose cannot be achieved; internal mark: it can only be found when the insect is caught, according to the purpose of the experiment, it is not feasible
