Description
Technical Field
The application relates to the technical field of agricultural pest control, in particular to a biodegradable thrips attracting and smearing adhesive and a use method thereof.
Background
Thrips are the collective name of Thysanoptera insects, the thrips are tiny, are often hidden in flowers and tender leaves to be harmful, have strong fertility and serious generation overlapping, have high outbreak frequency, accelerate the spread and harm of thrips pests through global trade and climate warming, and the thrips pests become one of the most important agricultural pest groups in the world gradually. Meanwhile, the pests can also transmit various plant viruses to cause indirect harm, such as frankliniella occidentalis, palmi thrips, soybean thrips and the like, and the indirect harm caused by the transmitted viruses is far greater than the direct harm to host plants. But the control of thrips pests at home and abroad still mainly depends on the use of chemical pesticides. The use of chemical pesticides in large quantities also causes serious environmental pollution and poses a threat to food safety. With the rapid development of research on insect chemical ecology, the technology of controlling by using information compounds has been widely applied to the comprehensive control of pests. The pest monitoring, trapping, feeding, spawning and mating interference technology based on the information compound is an important component of green pest prevention and control, and is widely applied to production.
The research of the thrips pheromone on the aggregation pheromone at home and abroad is the most extensive. The aggregation pheromone is produced by female insects and male insects or insects with any sex, has chemical substances with attracting effect on the female and male insects of the same species, and has important effects on the aspects of food source searching, habitat positioning, gathering and resisting external enemies, searching for opposite sex partners and the like of the same species of insects. The aggregation pheromone has attraction to female and male adults, so that the aggregation pheromone has greater application potential than the sex pheromone. At present, aggregation pheromone components of frankliniella occidentalis, palmi thrips and soybean thrips are separated and identified.
Because the insect pheromone has volatile components, the insect pheromone is easy to volatilize and degrade under natural conditions, and the slow release carrier is needed to protect the insect pheromone from environmental degradation, so that the insect pheromone is stably and uniformly released. At present, most of carriers carrying insect sex pheromones are composite rubber, PVC, paraffin oil and the like, and as disclosed in patent CN108041034B, the main material of the tea stick thrips aggregation pheromone attractant lure core is rubber; patent CN108902143B discloses that the main material of the soybean thrips aggregation pheromone attractant lure is also rubber; patent CN111296453a discloses that the main material of the frankliniella occidentalis attractant lure core is liquid paraffin; patent CN103141499B discloses that the main material of the banana flower thrips attractant lure is paraffin oil. The rubber head, capillary tube induced core and disorientation wire made of the slow release materials have the advantages of easy operation, but also have the defects of poor lasting effect, poor stability and the like.
