A device for luring and preventing adults of peach borer moth and its application

Abstract

The invention relates to a device for luring and preventing female adults of the peach moth moth and its application, comprising a trapping disk and a supporting and fixed column connected with the trapping disk; At the periphery of the bottom of the connecting portion and connected to the edge of the connecting portion, a tongue-shaped flower is arranged at the connection between the involucral bract and the connecting portion and above the connecting portion, and is located in the circle surrounded by the base of the tongue-shaped flower. The top of the connecting part is evenly distributed with end-sealed pipes and end-opened pipes, and the end-sealed pipes are arranged in a concentrated area. The present invention adopts physical methods to lure female adults of the peach borer moth to lay eggs on the surface of the trapping device, and utilizes natural transpiration Effect, light, temperature and other factors cause a large number of deaths of eggs and newly hatched larvae, and then by reducing the hatching rate of eggs and the mortality rate of newly hatched larvae, the purpose of prevention and control is achieved. The effect of field control of peach moth moth can reach more than 89.3%. Significantly reduce the hazard rate.

Description

technical field [0001] The invention relates to a device for luring and preventing female adult peach borer moths and its application, and belongs to the technical field of pest monitoring and prevention. Background technique [0002] Peach borer belongs to Lepidoptera, Mothidae, damages sunflower, castor, sorghum, corn, soybean, lentil, cotton, ginger family plants and other crops; chestnut, pomegranate, jujube, hawthorn, pear, plum, apricot, plum, Apple, grape, persimmon, cherry, walnut, citrus, sweet orange, navel orange, pomelo, loquat, longan, fig, litchi, mango, pineapple, papaya, ginkgo and other fruit trees; A very heterogeneous pest. The peach borer is extremely harmful, even destructive on some hosts. [0003] The peach borer is a moth-eating pest, which causes damage by larvae drilling. After the host is killed, the quality declines or the economic value is lost. Because the larvae of the peach moth borer feed on the host fruit, and the mature larvae mostly pu...

AI Technical Summary

Problems solved by technology

[0004] The control of peach borer eggs, newly hatched larvae and adults with chemical agents can inhibit the damage of the insect to a certain extent, but there are still many problems: 1) The timing of the application

In recent years, domestic attention has been paid to the screening of control agents and the prediction of the occurrence period of pests has been neglected, which often leads to poor control effects and half the effort

2) Pest resistance problem

But there are the following problems: 1) The sweet and sour liquid has a broad-spectrum trapping effect, which causes the death of a large number of natural enemy insects (such as hoverflies, ladybugs, parasitic wasps, etc.) of the peach borer while trapping and killing the adults of the peach borer; In addition, it has been criticized for its low booby-killing effect and frequent replacement of the liquid medicine.

2) Swatch trapping is also likely to cause the death of the natural enemy insects of the peach borer

However, its control effect is greatly reduced due to the characteristic that it can only trap and kill male insects.

In addition, in recent years, field trapping tests of peach borer moth attractants in Japan, South Korea and North China have shown that its attracting effect is generally low

At present, it is often only used as a means of forecasting
