Problems solved by technology

Because the outer surface of the container is coated with insecticide, even if the spotted winged fruit fly does not enter the container but only stays on the outer surface of the container, it can be killed, thereby overcoming the problem of the spotted wing in the prior art. The defect that the trapping and killing effect of fruit flies is not good

Embodiment Construction

[0046] The present invention will be further described below in combination with specific embodiments.

[0047] 1. Attractant

[0048] The attractants in the experiment include: rice wine, vinegar, molasses and water, and their proportions are 1:2:1:4. However, it should be noted that the ratio of these components is not limited to this. In the experiment, 100ml-400ml of attractant can be put in according to the volume of the container used.

[0049] 2. Pesticides

[0050] The main insecticide used in the experiment was deltamethrin. But because of various considerations, the concentration of 0.1% vegetable oil and ethanol was added simultaneously. Ethanol can be used as a solvent for pesticides, and will leave a thin layer of pesticides and vegetable oil after volatilization; since the surface of Drosophila spotted wing has oily substances, vegetable oil will help pesticides enter the insect body faster. It should be noted that, instead of adding vegetable oil and ethano...

Abstract

The invention relates to a trapping and killing device capable of effectively preventing damage of spotted-wing drosophilas. The device comprises an attractant containing volatile matter, a container containing the attractant and provided with holes, and water-insoluble pesticide coated on the outer surface of the container. According to the trapping and killing device, no pesticide needs to be sprayed on fruit crops of an orchard, and the effect of trapping and killing the spotted-wing drosophilas can be achieved by only coating the pesticide on the outer surface of the container, so that the environment can not be polluted, and the pesticide is not left on the crops in the orchard. The invention further relates to a method for trapping and killing the spotted-wing drosophilas through the trapping and killing device.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a trapping and killing device for effectively preventing and controlling the damage of spotted winged fruit flies. Background technique [0002] Spotted-winged Drosophila (Drosophilasuzukii) is a major pest of many orchard crops, including: cherries, blueberries, nectarines, strawberries, bayberry, grapes, etc. Spotted Drosophila first appeared in Japan and China, and has recently invaded other countries, such as the United States and Europe. Since the spotted wing fruit fly destroys fruit from the inside of fruits such as cherries, blueberries, nectarines, strawberries, bayberries, grapes, etc., even spraying insecticides on the outside of these fruits will not protect these fruits from the damage of spotted wing Drosophila . In addition, since the spotted-winged Drosophila begins to harm the fruits when the fruits of the orchard crops are about to mature, and this time ...
