Problems solved by technology

[0003] However, there are few in-depth research documents on the feeding tendency of crops by using pests, and there is no specific insecticidal technology scheme. It is necessary for those of ordinary skill in the art to carry out some research to reduce crops' exposure to pesticides. Rely on, improve product quality and added value

Embodiment 1

[0015] Example 1: Field surveys found that vegetable pests such as Prodenia litura (Fabricius) and diamondback moth (Plutellaxylostella Curtis) have relatively different feeding tropisms to different crops, especially when there are different crops in the same area. Sometimes, the adults of pests often choose to lay eggs on crops with strong feeding tendency, which leads to large differences in the occurrence of pests on different crops, as shown in the following table:

[0016] Table 1 Comparison of occurrence of Spodoptera litura larvae in different crops

[0017]

[0018] (The survey points are selected in the area where the two crops are adjacent to each other and planted in an area of ​​more than 2,000 square meters. Five points are used for sampling, evenly distributed, and 10 plants are investigated at each point.)

Embodiment 2

[0023] Example 2: The implementation method for the control of Spodoptera litura is: every 15-20 borders of leafy vegetables are interplanted with 1 border taro (Colocasia esculenta Schott.), and the intercropping ratio is 15-20:1. The method of field application is: from the middle and late October of each year to the middle and late June of the following year, it is only necessary to investigate the occurrence of Spodoptera litura on the taro, and to kill the pests intensively after the pests are found, without using them on leafy vegetables. Use of pesticides for prevention and control: From early July to early October every year, use pesticides on taro every 5 to 7 days, and use pesticides on leafy vegetables every 10 to 14 days or according to the occurrence of insect pests; the amount of pesticides in the field can be reduced by 40% throughout the year. %, reduce the risk of pesticide residues in leafy vegetables exceeding the standard, and realize efficient and safe cont...

Embodiment 3

[0024] Embodiment 3: The implementation method for the prevention and treatment of diamondback moth is: for every 4-6 furrow cabbage class (Brassica chinensis L.) vegetables interplant 1 furrow cabbage class (Brassica oleracea L.var.capitata Linn.) vegetables, the intercropping ratio is 4~6:1. The method of field application is: every 5 to 7 days during the period of high pest incidence from early May to late June every year on cabbage vegetables, and every 10 to 14 days or according to the occurrence of pests on cabbage vegetables; By the end of April of the following year, according to the occurrence of pests, pesticides are mainly used for control on cabbage vegetables, which can reduce the amount of pesticides in the field by more than 30% throughout the year, reduce the risk of pesticide residues in vegetables exceeding the standard, and achieve efficient and safe control of diamondback moth.

[0025] As a supplement: For the prevention and control of Spodoptera litura (F...

Abstract

The invention discloses an insect disinsection method by using taxis of pests to crops. The method is characterized in that a mode that a raise crop and a bait crop are intercropped or the bait crop is planted around the raise crop is employed to allure control objects to aggregate on the bait crop, then pests are centrally killed on the bait crop, and the pest amount of the raise crop is smaller than that on the bait crop. Compared with the prior art, the method has the advantages that the pests are allured to the bait crop and centrally killed by the feeding taxis of the pests so as to protect the raise crop, decrease the pesticide dependency of the raise crop, reduce the over-standard risk of pesticide residue, improve the quality and the added value of the product, and provide development and guarantee for food from greenization to organification.

Description

technical field [0001] The invention relates to a method for killing insects in the field, in particular to a method for killing insects by utilizing the feeding tendency of pests to crops. Background technique [0002] The method of using insect tropism to kill insects can significantly reduce the dependence on pesticides and contribute to the greening and organicization of food. At present, there are many methods used, such as using phototaxis to kill insects, using chromotropism to kill insects, and using hormones to kill insects. Sexual insecticide, as well as the oviposition and feeding tropism of pests. Patent documents such as ZL200620097780.7 Chinese utility model patent "Solar Photocatalyst Biological Sticky Insect Board" (authorized announcement number: CN200983802Y), this patent can attract and stick phototaxis, color, taste and chemotaxis pests. [0003] However, there are few in-depth research documents on the feeding tendency of crops by using pests, and there...
