Vegetable insect pest swatch trapping prevention and control technology
The swatch (yellow, blue plate) trapping technology is the yellow, blue adhesive pest trap (referred to as "yellow"), which uses the characteristics of certain insect pests to be sensitive to yellow or blue and has strong tropism. Board, blue board) technology suspended in the field to physically trap pests. The technology follows the concept of green, environmental protection and pollution-free prevention and can be widely used in the pollution-free prevention and control of various vegetable-related pests. The technical points are as follows:
First, the object of prevention
Hemiptera locusts, whitefly, leafhopper, etc., Dynamidae, Drosophila, etc., Thrips.
Second, hanging board time
The use of vegetables from the seedling stage or planting stage, and maintaining uninterrupted use can effectively control the development of pests.
Third, the suspension method
Use a wire or rope to pass through the hanging hole of the trap board, fix it, and hang both ends of the trap board vertically in the upper part of the greenhouse. In the open environment, sticks or bamboo pieces should be used to fix the trap board. Side, then insert underground and fix it.
Fourth, the suspension position
For dwarf vegetables, the armyworm board should be hung from the upper 15 to 20 cm from the vegetable, and the height of the armyworm board can be adjusted continuously with the height of the vegetables. The vegetables should be straight along the scaffolding, so that the trap board is hung vertically in the middle of the middle of the two rows of plants.
V. Suspension density
Controls locusts, whiteflies, leafhoppers, and leafminers. 3 to 5 yellow insect traps can be hung in the shed or open space to monitor the density of insect populations. When the number of insect attracting insects on the insect trap increases, they are hung from each acre. The size of 25 cm 30 cm yellow trap board 30 or 25 cm 20 cm yellow trap board 40 can be, or increase the number of traps as the case may be.
To prevent and control species fly, 3 to 5 blue insect traps can be hung in the greenhouse or open field to monitor the density of insect population. When the amount of insect attraction on the insect trap increases, a 25 cm 40 cm blue trap is suspended per acre. 20 pieces of insect board or 40 cm of 25 cm 20 cm blue trap board can be added, or the number of insect traps can be increased as appropriate.
To control the thrips, 3 to 5 blue insect traps can be hung in the greenhouse or open field to monitor the population density. When the amount of trapped insects on the trap board increases, 20 pieces of blue traps with a size of 25 centimeters and 40 centimeters or 40 pieces of 25 centimeters with 20 centimeters and 20 centimeters of blue traps may be suspended per acre, or the trap board may be increased as appropriate. Quantity.
Sixth, late processing
When there are a large number of pests sticking on the trapping board, scraping off the body with a wooden stick or a hacksaw can be repeated.
