Description

Yunnan longicorn attractant and application thereof

Technical Field

The invention belongs to the field of forestry insect prevention and control, and particularly relates to a anoplophora malasiaca attractant and application thereof.

Background

The long-horned beetles are important tree trunk-boring pests, can damage nearly hundreds of broad-leaf trees such as poplar trees, walnut trees, Chinese chestnuts, birchleaf pears, white wax and the like, and are widely distributed in large provinces of China at present, particularly China and eastern China. The fast-growing and high-yield forest of poplar in southwest and other places is seriously damaged, the poplar is damaged by the Yunnan longicorn, the tree vigor is weak if the poplar is damaged by the Yunnan longicorn, and the whole poplar is withered if the poplar is heavy; meanwhile, the damage of poplar materials is caused, the material grade is reduced, and the economic benefit and the ecological benefit are greatly lost.

The long-horned beetles belong to the metamorphosis insects, the larvae of the long-horned beetles are mainly damaged by trunk borer, the larval stage reaches 12-14 months, after the adult long-horned beetles emerge from pores, nutrition needs to be supplemented to a nutrition host, nutrition supplementation and mating are carried out for a period of time, and after sexual maturity is reached, the long-horned beetles lay eggs on poplar trees. The damage of the longicorn is mainly concentrated in the larval stage, the larva is damaged by boring, the individual is large, the borer is long and deep, wood dust and excrement are filled in the borer, the borer is often staggered in the trunk of a damaged tree, the damaged tree is withered or folded, and the codling moth and wood rot fungus are parasitized. During the period of supplementing nutrient substances, adults gnaw the cortex of the tender branches of nutritional hosts such as pear trees, shaddock trees and the like, so that fruit trees cannot bear fruits and the like.

Eggs, larvae and pupae of the long-horned beetles are hidden in the trunk, and the larvae have complicated holes and are dispersed and harmful, so that the prevention and the control of the larvae are difficult, and time and labor are wasted; the adult body wall and the coleoptera are thick and hard, the protection mechanism is perfect, the eclosion period is dispersed, and the effect of general chemical control is difficult to achieve.

At present, the following methods are mainly used:

1. artificially killing adults: the adult is usually checked in the growing period, and the adult is trapped and killed by holding a lamp in the evening or manually catching the adult in the morning by utilizing the characteristics of phototaxis, no tendency to fly, slow action and sound after being frightened.

2. Killing eggs and larvae hatched initially: and (3) checking the place where the adult eggs lay grooves or run black water in the egg laying period, searching for eggs, and digging with a knife or smashing the eggs with a hammer and the like. In the full-term incubation period, 5-10 times of liquid medicine of 50% phoxim missible oil is smeared at the carving groove of egg laying to kill the larvae which are hatched at first.

3. Killing harmful larvae in the full stage: in the trunk-boring damage period of the larvae, when the trunk is found to be discharged with excrement, peeling off the skin by using a knife to dig out the larvae; or 100 times of liquid of 50 percent dichlorvos missible oil is injected into the discovered wormholes, then the holes are sealed by mud, and the wormholes can be blocked and sealed by medicine mud or cotton balls soaked with medicine, so that the internal pests are killed by poison. The iron wire is inserted into the wormhead to stab up the larvae, or the iron wire is used to hook out the insect manure in the wormhead, and then the aluminum phosphide poison stick is plugged into the Yunnan beetle to be invaded into the holes and sealed by mud, thus the effect of fumigating and killing the adults and the larvae is remarkable.

4. Coating the trunk with the medicine: in winter or before spawning, 5 kg of lime, 0.5 kg of sulfur, 0.25 kg of salt and 20 kg of water are evenly stirred and then coated on the base of the trunk to prevent adults from spawning and kill larvae.

The attractant provided by the invention can efficiently and specifically attract female adults, so that the purpose of concentrated trapping is achieved, the egg laying amount of longicorn can be remarkably reduced, the insect population density in the next year is reduced, and the purpose of prevention and treatment is achieved.
