The technology of trapping and killing of pests by slime swatches is a physical control technology that utilizes the tendency of pests to trap and kill pests. Different vegetable pests have different sensitivities to different colors. For example, the yellow-and-white skeletal hawksmanship of the yellow-trickle-jelly beetles is the most sensitive to yellow, and the adults of the diamondback moth are most sensitive to green, and most of the pupa are particularly sensitive to blue. Using insect pests' color-rendering properties, insecticide boards of various colors are made to trap vegetable pests.
1, trapping vegetable pest species
After many years of experimentation, the common locusts, whiteflies, leafhoppers, and other insect pests of the order Diptera, Drosophila, and Drosophila, and Pterygium pygmaea, etc., have a strong tropism towards yellow and blue and can pass. Hang yellow and blue traps to trap. The stickworm swatches can not only kill and kill small insects such as aphids, whiteflies, migratory locusts, leafhoppers, leafminers and thrips, but also have control effects on crop virus diseases caused by these insects.
2, field application method
(1) The application time and suspension method are used starting from the vegetable seedling and planting period. Use a wire or rope to pass through the two hanging holes of the trap board, fix it, and hang both ends of the trap board vertically above the greenhouse. In the open environment, sticks or bamboo sticks should be used to fix the traps on both sides of the trap, and then be inserted into the ground to fix them. For low-lying vegetables, stick insect swatches should be suspended 15-20 cm from the top of the vegetables. And adjust the height of the slime swatches in time with the crop growth. For whiteflies with strong tenderness, the height of hung yellow plates was the highest along the height of 15 cm above the top of the vegetable plant; the suitable height of the yellow plate to attract mites was 32-40 cm; the yellow flea beak was captured. The appropriate height for L. sativae is 4-20 cm. The vegetable should be straight forward. The trap board is hung vertically on the middle or upper part of the two rows of vegetable plants.
(2) According to the occurrence of local pests, determine the type and amount of slime swatches to be installed to control pests such as aphids, whiteflies, leafhoppers, and leafminers, and start hanging 3-5 yellow insect traps to monitor the population density. When the number of insect traps on the trapping board is increased, 30 pieces of yellow insect traps with a size of 2530 cm or 40 pieces of yellow trap plates with 2520 cm are suspended per acre, or the number of insect traps is increased depending on the actual situation. To prevent pests such as species fly and thrips, 20 pieces of 2540 cm blue insect traps or 40 cm of blue insect traps are to be hung per acre, or depending on pests, increase the number of traps. When there are a large number of pests sticking on the trapping board, the worm body can be scraped off in time with a hacksaw blade or wood or bamboo, and the insect trap board can be reused.
3, matters needing attention
(1) The start time of the stickworm swatches should be suitable after the vegetables are seedlings, which can effectively control the breeding quantity and spread speed of pests. And with the height of the vegetables to increase the height of the sticky board. When the growth of vegetables reaches a certain height, the stick board can be hung between vegetable plants where the pests are most dense.
(2) The trapping effect of sunny days is obviously better than cloudy days. The tendency of pests to color is much greater than when they are stationary. If you tap the plant with the whitefly on your hands, the adults of Bemisia tabaci will swarm toward the yellow plate in groups and the speed, distance, and quantity of the whiteflies on the plant will not flutter toward the yellow plate. Less than. Pasteworm swatches should be used in conjunction with other comprehensive control measures to more effectively control pests.
(3) Worm-eaten swatches should be made of products that are resistant to rain and UV rays. The main components of viscose are non-toxic pressure-sensitive adhesives. If they stick to your hands, they can be cleaned with detergents or solvents.
