Problems solved by technology

[0004] Sex lures 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.

Embodiment 1

[0017] The sex lure lure core and the moth trap are fixed on the bamboo pole after being assembled according to routine, and the bamboo pole is inserted in the smoke soil, and ensure stability, and also include the following operations: the vertical distance between the insect inlet of the trap and the moisture surface is 130cm, each bamboo pole is fixed with a trap, arranged in a checkerboard pattern (criss-cross) in the field, the initial period of trapping is from the time when the tobacco seedlings are transplanted to the period when the tobacco plants are placed on the plate, and the trapping time is not less than 60 days, until the leaves in the middle are harvested. After the roasting is over, the replacement period of the sex attractant lure core is 40 days. The distribution density of traps is determined according to the planting area. The number of traps placed in each part of the field is planting tobacco boundary>central point>secondary center.

Embodiment 2

[0019] The sex lure lure core and the moth trap are fixed on the bamboo pole after being assembled according to routine, and the bamboo pole is inserted in the smoke soil, and ensure stability, and also include the following operations: the vertical distance between the insect inlet of the trap and the moisture surface is 110cm, each bamboo pole is fixed with a trap, arranged in a checkerboard pattern (criss-cross) in the field, the initial period of trapping is from the time when the tobacco seedlings are transplanted to the period when the tobacco plants are placed on a plate, and the trapping time is not less than 60 days, until the leaves in the middle are harvested. After the roasting is over, the replacement period of the sex attractant lure core is 60 days, the distribution density of traps is determined according to the planting area, and the number of traps placed in each part of the field is tobacco planting boundary>central point>secondary center.

Embodiment 3

[0021] The sex lure lure core and the moth trap are fixed on the bamboo pole after being assembled according to routine, and the bamboo pole is inserted in the smoke soil, and ensure stability, and also include the following operations: the vertical distance between the insect inlet of the trap and the moisture surface is 150cm, each bamboo pole is fixed with a trap, arranged in a checkerboard pattern (criss-cross pattern) in the field. The initial period of trapping is from the transplanting of the tobacco seedlings to the period of placing the tobacco plants on the plate, and the continuous trapping time is not less than 60 days, until the middle leaves are harvested and roasted At the end, the replacement cycle of sex lure lure cores is 30 days, the distribution density of traps is determined according to the planting area, and the number of traps placed in each part of the field is tobacco planting boundary > center point > sub-center.

Abstract

The invention discloses a method for preventing and controlling tobacco pests, namely prodenia litura 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 to a moisture surface is set as 110 to 150cm; each bamboo pole is fixedly provided with one trapper; an initial period of trapping is a period from tobacco seedling transplanting to tobacco plant placing; 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 prodenia litura by the sex attractants, the control efficiency on the prodenia litura is 81.09 percent to 94.43 percent. By using the sex attractants to prevent and control the prodenia litura, 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 the usage amount of chemical pesticides are reduced, the environmental pollution is reduced, and beneficial organisms are protected.

Description

technical field [0001] The invention relates to a method for controlling tobacco pest Spodoptera litura with a sex attractant, and belongs to the technical field of agricultural and forestry pest control. Background technique [0002] Spodoptera litura, tobacco budworm, etc. 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 the harm of 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), economi...
