Pest-killing lamp and using method thereof

Abstract

The invention discloses a pest-killing lamp and a using method thereof, belonging to the technical field of pest killing for crops. The pest-killing lamp comprises a lamp pole and also comprises a height adjustable device used for adjusting the height of the pest-killing lamp, wherein the bottom part of the pest-killing lamp is 25-100 cm higher than the height of a crop canopy. The using method for the pest-killing lamp comprises the following steps: a, fixing pest-killing lamps in a field at intervals, wherein one pest-killing lamp is fixed around per 2000-33350 square meters; b, carrying outpest-killing operation, wherein the time period from the beginning of early spring overwintering generation of pests to the ending of the early winter imago generation period of the pests is a pest-killing period in the north area, while the time period from the beginning of early spring overwintering generation of the pests to the ending of the pest activity period is the pest-killing period inthe south area; and c, adjusting the height of the pest-killing lamp, and allowing the height of the pest-killing lamp is always 25-100 cm higher than the height of the crops along with the growth ofthe crops. The pest-killing lamp provided by the invention has the characteristic of high pest-killing efficiency.

Description

technical field [0001] The invention relates to the technical field of crop insecticide. Background technique [0002] Insect pests have become the main problem affecting the growth and quality safety of farmland crops. The types of crop pests in farmland mainly include cotton bollworm of Lepidoptera, corn borer, armyworm, spodoptera, peach borer and other moths and scarabs of Coleoptera. Cotton bollworm has a mixed diet and can harm almost all farmland crops such as cotton, corn, millet, sorghum and vegetables; corn borer mainly harms corn, sorghum, millet and other crops; armyworm mainly harms millet, corn, sorghum and other crops; The moth mainly harms the seedlings of summer corn; the peach borer mainly harms sorghum, corn and fruit trees; the larvae of the scarab are important underground pests, and the adults feed on various crops such as corn, millet, sorghum and vegetables to cause harm; the rice leaf roller, two Chilophoridae, Chilophoridae and other pests mainly ...

AI Technical Summary

Problems solved by technology

At present, there are technical means to trap and kill the above-mentioned pests by using insecticidal lamps. Since the growth of crops gradually grows taller from low to high, the height of the currently used insecticidal lamps cannot be adjusted, so the protection of insecticidal lamps cannot be guaranteed. In the activity range of pests located above the canopy, the maximum design of insecticidal lamps currently used is generally 3.5 meters. The plant height of corn, sorghum and other crops after earing can reach about 2.7 meters, and the maximum height of waxy corn can reach 3.5 meters. Therefore, , the insecticidal lamp installed in this kind of farmland, after the crop grows tall, the lamp tube cannot expose the canopy, and the effect of attracting adults is seriously affected, or because the crop growth stage is low, the insecticidal lamp is more than 25cm higher than the crop canopy, Higher than the pest activity range, resulting in low insecticidal effect

Limit the use and promotion of insecticidal lamps in pest control

A female pest can lay 300-500 eggs in the oviposition period before the overwintering generation in early spring. At present, the insecticidal lamp only traps and kills the pests in the outbreak period, but does not trap and kill the pests in the oviposition period before the overwintering generation in early spring. Causes a geometric exponential increase in the number of second or third generation larvae
