The experimental area has a vegetable area of ​​15hm2. In the center of the vegetable field and around the ground, 20 solar insecticidal lamps were installed through the underground cement blocks, arranged in a checkerboard pattern, and the distance between the lamp and the lamp was 150-200 m. 1 lamp control vegetable field area 1 to 1.33hm2. Solar insecticidal lamp larvae from the ground height 1.3 ~ 1.5m. Automatically lights up from 8:00 PM to 2:00 AM, and turns off automatically the rest of the time. Every 15 days, the carcasses were cleaned and water was added.
The main performance of the trapping of natural enemies is small: Solar insecticidal lamps are used to trap vegetable pests and have minimal damage to natural enemies. According to statistics, a total of 32 natural enemies such as ladybugs, ladybugs, and bees were captured, which accounted for 0.48% of the total insect traps. The ratio of hazards to harm was 1:207. This shows that solar-powered insecticidal lamps have minimal damage to natural enemies, and have a strong specificity for trapping and killing of insect pests, and are safe to use. They can effectively protect natural enemies and promote ecological balance in the field.
The use of solar insecticidal lamps can significantly reduce the number of pests per vegetable crop in the vegetable field, reduce the use of chemical pesticides, and reduce the use of chemical pesticides by 25% to 25%. Reducing the use of pesticides and reducing farmland environmental pollution and pesticide residues in vegetable samples have little effect on natural enemies. Save work, save time, reduce work load on labor, kill insects can improve the quality of product safety and quality of vegetables, solar insecticidal lamp can also improve the competitiveness and system of green food, maintain the sustainable development of the vegetable industry, economic efficiency, Social and ecological benefits are significant.
Carbomer Carbopol 940,also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of acrylic ACID used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics. They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. Carbomers are found in the market as white and fluffy powders. They have the ability to absorb, retain water and swell to many times their original volume. Carbomers codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer . This product is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymer. Calculated on dry goods, including carboxylic acid group (-cooh) group - should be 56. 0 % ~ 68. 0 %.
