Device for inducing, preventing and controlling adult dichocrocis punctiferalis and application

Abstract

The invention relates to a device for inducing, preventing and controlling adult dichocrocis punctiferalis and application. The device comprises an inducing flower disc and a support fixing column connected with the inducing flower disc; the inducing flower disc comprises a phyllary and a connecting part, the phyllary is arranged on the periphery of the bottom of the connecting part and connectedwith the edge of the connecting part, tongue-shaped petals are arranged on the upper portion of the junction of the phyllary and the connecting part, end head sealed pipes and end portion open pipes are evenly arranged in the circumference defined by the base parts of the tongue-shaped petals and located on the upper portion of the connecting part, and the end head sealed pipes are centralized andarrayed into an area; according to the device, a physical method is adopted for inducing female adult dichocrocis punctiferalis to lay eggs on the surface of the inducing device, and natural transpiration, illumination, temperature and other factors are utilized to cause a large number of deaths of eggs and newly hatched larvae, so that the hatching rate of the eggs is reduced, the mortality of the newly hatched larvae is increased, and therefore the prevention and control purpose is achieved; field prevention and control of dichocrocis punctiferalis are conducted, the rate can reach 89.3% orabove, and the hazard rate is significantly reduced.

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 pest damage to a certain extent, but there are still many problems: 1) The problem of the period of 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) The problem of pest resistance

But there are following problems: 1) the trapping and killing effect of sweet and sour liquid has broad-spectrum property, causes the natural enemy insect (as: hoverfly, ladybug, parasitic wasp etc.) of a large amount of peach moths to die when trapping and killing the peach borer adult; In addition, it has been criticized for its low booby-killing effect and frequent replacement of the liquid medicine.

2) Trapping and killing with swatches can also easily 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
