Method and device for efficiently separating beneficial and harmful insects

Abstract

The invention discloses a device for efficiently separating beneficial and harmful insects. The device comprises an insect collecting box, a device base and an internal box, wherein the top of the insect collecting box is provided with a funnel-shaped insect inlet, the wall of the insect collecting box is encircled by a netlike object, and the wall of the internal box is also encircled by a netlike object; the internal box is fixed on the device base in the center of the insect collecting box; and the bottom of the insect collecting box is connected with the upper part of the device base, and a plurality of natural enemy escape holes are formed at the connected position. According to the device, the aims of killing pests and separating beneficial insects are fulfilled by the way that the pests are eaten by natural enemies of the pests, so that the survival rate of the beneficial insects is greatly improved; and eggs laid by lepidoptera insects provide hosts for the propagation of trichogramma, so that the cost of indoor bee propagation is reduced to a great degree. The natural enemy number of the pests in fields is remarkably increased, so that the number of the pests in the fields is effectively controlled, and the use of chemical agents is reduced and even eliminated; and the device is an indispensable professional insect attracting facility for the development of ecological agriculture.

Description

technical field [0001] The invention relates to the technical field of deworming crops, in particular to a method and device for efficiently separating beneficial and harmful insects. Background technique [0002] At present, with the acceleration of the process of a well-off society in rural areas and the improvement of the living standards of urban and rural residents, the quality and safety of agricultural products and the ecological problems of agriculture and rural areas have become more prominent. It is necessary to meet the diversified food consumption needs under the condition of continuous population growth, ensure the quality of agricultural products and food hygiene and safety, reduce and control agricultural and rural pollution, and effectively curb the depletion of natural resources and the deteriorating trend of the ecological environment. The development of ecological agriculture under the condition of market economy brings new challenges. For a long time, pe...

Problems solved by technology

As a result of the long-term accumulation of pesticide residues in the soil, trace amounts of pesticide residues appear in crops and livestock products, polluting food and endangering human health; while some chemical agents (organochlorine pesticides, etc.) not only have killing and poisoning effects on pests, At the same time, it also has a killing effect on the "natural enemies" of pests and beneficial insects and birds such as pollinators, thus destroying the ecological balance of nature.

In order to solve these problems and seek sustainable agricultural development, scientists have proposed the production model of ecological agriculture. In the last ten years, various field insecticidal equipment have appeared on the market, among which insecticidal lamps have been widely used. Applied in agricultural production, however, insecticidal lamps kill all beneficial insects (mainly natural enemies of pests) while trapping and killing insects, resulting in a serious reduction in the number of natural enemies of pests in the field. When pests occur on a large scale, due to the serious number of natural enemies in the field Insufficient and unable to control the pests in the field, we can only use other methods to eliminate pests, such as spraying chemical agents, etc., which will inevitably lead to a decline in the yield and quality of agricultural products, and it is also a great loss to ecological agricultural production
