Embodiment 1

[0022] A kind of American white moth comprehensive control method, comprises the steps:

[0023] (1) Release 3 times of the white moth Chow's gnats at the larval stage of the American white moth and the initial stage of pupation, and release the bees continuously for 2 generations;

[0024] (2) Cut off the larvae screen and harmful branches in the young larva stage, and burn the cut branches and the net screen away from the garden; spray plant pesticides on young larvae; wherein the plant pesticides include the following weight percentages Raw materials: matrine 0.3%, nano silicon dioxide 0.6%, abietic acid polyoxyethylene ether 0.5%, sodium lignosulfonate 0.5%, ethylenediamine polyoxypropylene ether 0.3%, water balance;

[0025] (3) Before the mature larvae start to pupate down the tree, tie the trunk 1 meter above the ground with dry straw for a week, and lure the mature larvae to pupate therein. During the pupation period, every 7 The grass handles are changed once a day, ...

Abstract

The invention belongs to the technical field of agriculture, and discloses a comprehensive control method for hyphantria cunea. The control method comprises the following steps that (1) in the larvalphase and the pupating early stage of hyphantria cunea, hyphantria Chouioia cunea Yang are released continuously for prevention and control for two generations; (2) in the low-age larvae period, a larvae net curtain and harmful branches are pruned, the cut branches and net curtain are removed from an orchard to be burnt down in a concentrated mode; plant insecticides are sprayed to the low-age larva; and (3) before the old aged larva begin to leave a tree for pupating, a place of 1-1.5 meters from the ground of the trunk is bundled by grass for one circle for trapping aged larva to pupate in aconcentrated manner; and (4) hyphantria cunea adults are trapped by a trapper, wherein the trapper is provided with a trapping agent composition, and hyphantria cunea are cleared from the trapper intime. According to the method, different insecticidal means are adopted according to different growth periods of the hyphantria cunea, and artificial physical control, biological control and chemicalcontrol combined means are adopted, so that the insect mouth cardinality and propagation diffusion of the hyphantria cunea are thoroughly controlled.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and relates to a method for comprehensive prevention and control of white moth. Background technique [0002] The American white moth is a leaf-eating pest. Its host plants are of many types, its damage range is wide, and its spread speed is fast, causing serious ecological disasters. It is a worldwide quarantine pest. Since the American white moth invaded my country in the last century, it has gradually become the main pest harmful to my country's forestry in recent years, and it has a wide range, a large area of ​​occurrence, and high losses. The situation of shortening and increasing difficulty in prevention and control. The American white moth mainly harms common tree species such as poplar, willow, and paulownia in my country. In some areas, it also breaks out on plants such as mulberry and corn, and even cases of harm have been found on ginkgo trees. [0003] The existing American whit...
