Description

Containing and releasing device for predatory natural enemies

Technical Field

The utility model relates to a biological prevention and control technical field of pest, concretely relates to predatory natural enemy holding release.

Background

Biological control refers to a control method that utilizes beneficial organisms to control the development of pest populations. The essence of the method is that the population density development of harmful organisms is adjusted by utilizing the predation or competition relationship among species, namely, the biological groups control the biological groups. The use of predatory natural enemies for pest control is an important biological control measure and also an important component of the feedback mechanism of biological control systems. One natural enemy tends to prey on a variety of pests, one pest being preyed on by a variety of groups of natural enemies. Therefore, according to the food chain relationship between predatory natural enemies and prey, and some natural ecological principles and laws, the dynamic balance relationship between new biological populations can be reestablished in the agricultural ecosystem.

Agricultural and forestry workers and scientific researchers can complete field release and accurate counting of natural enemies of insects in a large scale by using the releaser of the natural enemies of the insects, thereby realizing development and application of corresponding products of standardized, modernized and accurate management of biological prevention and control. Currently, the releasers for biological control are mainly simple open containers or semi-open containers with gauze, and the design and use of such releasers have the following four defects: firstly, the releaser is mainly used for releasing social predatory natural enemy groups, such as lacewing flies, ladybugs, stinkbugs, predatory mites, parasitic bees and the like, and the releasing difficulty of spiders which are the important social predatory natural enemy of the independent type is high, and the phenomenon that the spiders attack each other and even predate among spiders in the same releaser is easily caused by the independence of the spiders; secondly, the releaser is generally hung in the field and is more prominent than the surrounding environment, so birds, ants, reptiles and the like are easy to attract and enter the releaser to prey on natural enemies of insects, and the prevention and control effect is not ideal; thirdly, the releaser is usually hung in the air and is dried by wind, so that the natural enemies of the insects cannot be moisturized, and the aim of releasing the natural enemies of the insects as much as possible is difficult to achieve; and fourthly, some predatory natural enemies with netting habits, such as spiders, are difficult to handle during release by storing and transporting in conventional containers, and the predatory natural enemies can be difficult to net in the containers and release one by one.

The field needs to develop a novel releaser which has simple structure, ensures the normal habit of predatory natural enemies, and simultaneously can realize safe and convenient storage and transportation and convenient release operation.
