Enclosure type foam niphades castanea chao trap

Abstract

The invention discloses an enclosure type foam niphades castanea chao trap, and belongs to the technical field of Chinese chestnut pest prevention and control. The enclosure type foam niphades castanea chao trap comprises a heat insulation box, an insect collecting box, a tooth-shaped plate, foam plastic blocks and a marble block, wherein the heat insulation box is a box with an opening and a cover, and is in an integral shape formed by hollowing a hexahedron from the inside of a quadrangular frustum pyramid from the upper bottom surface and one side surface. The insect collecting box is arranged in an insect collecting chamber defined by an upper chamber, a left chamber, a rear chamber and a right chamber; the bottom surface of the insect collecting box is provided with a plurality of round through holes; a pest inlet is formed in the insect collecting box. The tooth-shaped plate is inserted and connected onto a groove formed in the side surface of the heat insulation box. The four foam plastic blocks are respectively put in the upper chamber, the left chamber, the rear chamber and the right chamber. The marble block is put in a groove of the upper foam block. The trap can be used for preventing and controlling the insect, i.e., niphades castanea chao; in addition, chemical pesticides are not used; the operation is convenient; the cost is low; the environment pollution can be avoided; the food safety is ensured; the agricultural production benefits are improved.

Description

technical field [0001] The invention relates to the technical field of chestnut pest control, and belongs to a device for preventing and controlling pests, in particular to an enclosing foam-type chestnut snowflake trap. Background technique [0002] Chestnut snow flakes are the main pests in the production process of chestnuts. Damage to chestnut buds will cause chestnut fruit drop, resulting in reduced yield, and damage to fruits will cause chestnut commodity rate to decline. The prevention and control of the chestnut snowflake pest is a big problem in the chestnut industry. In recent years, the occurrence and spread of chestnut snowflakes has been very serious, with a large area of ​​occurrence, occurring in most chestnut producing areas; the degree of damage is serious, and the weather is slightly suitable for the year when chestnut snowflakes occur, and the fruit drop rate of many chestnut orchards is 80% Above, there are often large areas of chestnut orchards contiguo...

AI Technical Summary

Problems solved by technology

Due to the concealment and drug resistance of chestnut weevil adults, the commonly used chemical measures have little effect, and the insecticidal rate does not exceed 3%. Chestnut weevil larvae have occurred inside chestnut buds since the beginning, and chemical pesticides cannot kill them. it

Therefore, farmers use highly toxic and high residual pesticides and increase the amount of pesticides for control, but the effect is still poor, not to mention the greatly increased labor and cost, and it also causes environmental pollution and excessive pesticide residues in chestnut fruits.

However, there is currently no device for preventing and controlling chestnut snowflakes
