The method of preventing and controlling the tobacco pest small cutworm with sex attractant

Abstract

The invention discloses a method for preventing and controlling tobacco pests, namely black cutworms by sex attractants. The method comprises the steps that lure cores of the sex attractants and trappers are conventionally assembled, then the lure cores of the sex attractants and the trappers are fixed on bamboo poles, the bamboo poles are inserted into tobacco moisture soil and the stabilization is guaranteed, the method further comprises the following operations: the vertical distance from a pest entering inlet of each trapper to a moisture surface is set as 100 to 150cm; each bamboo pole is fixedly provided with one trapper; an initial period of trapping is a flowering period of preceding crops; the continued trapping time is not less than 60 days; the distribution density of the trappers is determined by virtue of the planting area; the number of the trappers installed at each part of the field is that the boundary of tobacco planting is greater than a central point greater than a subcenter. According to the method for preventing and controlling the tobacco pests, namely the black cutworms by the sex attractants, the control efficiency on the black cutworms is 81.09 percent to 94.43 percent. By using the sex attractants to prevent and control the black cutworms, the amount of labor is effectively reduced, the prevention and control cost is lowered, and good economic benefit and social benefit are achieved, meanwhile, the use number and usage amount of chemical pesticides are reduced, the environmental pollution is reduced, beneficial organisms are protected, and good environmental benefit and ecological effect are achieved.

Description

technical field [0001] The invention relates to a method for controlling tobacco pests cutworms with a sex attractant, and belongs to the technical field of agricultural and forestry pest control. Background technique [0002] Small cutworm and tobacco budworm are the main pests in the tobacco area, which not only cause direct loss of yield and economic benefits to tobacco leaf production, but also use a large amount of chemical pesticides to prevent and control pests, which will easily cause ecological pollution and pesticide residues in tobacco leaves, which seriously restricts the production of tobacco leaves. sustainable development of tobacco leaves. [0003] As people pay more attention to environmental safety and food safety, sex attractants, as a technical means to replace chemical pesticides to control pests, have received more and more attention in the fields of agriculture and forestry. Therefore, food crops (such as rice, corn), economic Crops (such as vegetable...

AI Technical Summary

Problems solved by technology

[0004] Sex attractants have the advantages of high efficiency, non-toxicity, no harm to beneficial insects, and no pollution to the environment. Insufficient investigations and researches on the occurrence and prevalence of such diseases, widespread non-standard use, poor grasp of the best use period and range of use, and improper use methods, etc.

On the other hand, due to the large variety of sex attractants, there is almost no evaluation of the trapping and killing effects of various sex attractants in various places, and there is a large blindness in the purchase of sex attractants for large-scale production and application.
