Lepidoptera pest attractant and preparation method thereof

Abstract

The invention discloses a trapping agent for lepidopteran pests, which belongs to the technical field of agriculture. The trapping agent is composed of brown sugar, vinegar, water, gelatin, pectin and agar. The field is resistant to rain erosion, hot sun exposure, long-lasting effect, reduced replacement frequency, and reduced labor input; simple formula, good trapping effect, ecological environmental protection, inheriting the traditional concept of safety and greenness, low cost of raw materials, and the trap after use can be recycled Therefore, the input cost is reduced; when the trapping agent of the present invention is used, the worm body will not appear in the net-like trapping device, and the phenomenon of foul smell will not occur after soaking in water for a long time, and the trapping effect will be increased; the preparation method of the present invention is simple to operate, convenient to prepare, Low cost and suitable for industrialized mass production.

Description

Technical field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a lepidopteran pest attractant and a preparation method thereof. Background technique [0002] Lepidopteran moths and butterflies contain many important agricultural pests, including cotton bollworm, tobacco armyworm, cutworm, armyworm, Spodoptera litura, silver moth, beet armyworm, cabbage moth, diamondback moth, leaf roller, etc. , Almost all are herbivorous groups. Currently, its control mainly relies on the use of chemical pesticides in the larval stage. About 95% of the pesticides are used for the control of lepidopteran pests, which has caused a serious "3R" problem. Although transgenic Bt crops have good inhibitory effects, they still lead to obvious secondary pests resurgence (such as Lygus, Bemisia tabaci, etc.), and the potential health risks to the human body have not yet established scientific evaluation standards. The number and distribution of eggs of le...

Problems solved by technology

[0012] Pests are not easy to enter. Field practice has proved that this type of trap has poor effect, large volume and high cost;

[0013] (4) Traps with light, power supply, heat, air negative pressure or ultrasonic waves, etc., such as Chinese patents 200920190971, 200720183666, this type of trap is combined with high technology, and the trapping efficiency is high, but it occupies a large area. Poor performance, requires power supply and wires, and is not easy to popularize and apply in farmland

Adults of Lepidoptera have a keen sense of smell, and they move to the liquid when they smell the smell. The worms stick to the liquid and cannot fly, and finally drown in the liquid. This method has a better trapping effect in the field, but the smell of the liquid is easily affected by the rot of the worms. , the trapping and killing can no longer be carried out after the insect body floats in the liquid, and the liquid volatilizes quickly in the field and is easily diluted by heavy rain.
