Land plugged type trapping device for niphades castanea chao

Abstract

The invention discloses a land plugged type trapping device for niphades castanea chao, and belongs to the technical field of castanea mollissima pest control. The device comprises a functional box and a calcium silicate board for heat insulation. The functional box is made from opaque materials and composed of a pest collection chamber, a heat insulation chamber, a toothed inlet and a fixing pile. The pest collection chamber and the heat insulation chamber are connected to form a box body in a cuboid shape. The pest collection chamber is located on the lower portion of the box body, a cavity is formed inside the pest collection chamber, and the bottom face of the pest collection chamber is provided with a plurality of circular through holes. A pest inlet is formed in the pest collection chamber. The heat insulation chamber is located on the upper portion of the box body. A cavity is arranged inside the heat insulation chamber. The top of the heat insulation chamber is provided with an opening and a cover, and the side face of the heat insulation chamber is provided with a handle. The side face of the box body is provided with the toothed inlet. The fixing pile is arranged below the bottom face of the pest collection chamber. The calcium silicate board for heat insulation is located in the heat insulation chamber and matched with the inner cavity of the heat insulation chamber in shape. The trapping device can prevent and treat niphades castanea chao, no chemical pesticide is used, operation is convenient, the cost is low, environmental pollution can be avoided, food safety can be ensured, and agricultural production benefits are improved.

Description

technical field [0001] The invention relates to the technical field of chestnut pest control, and belongs to a pest control device, in particular to a ground-inserted 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 contiguous in multiple administrative...

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
