AI Technical Summary

Problems solved by technology

In recent years, the neem tree tortrix has spread all over the planting areas of Meliaceae plants in various southern provinces, and the damage is becoming more and more serious, which affects its utilization value

[0003] The larvae of the neem moth feed on the leaves and are explosive. At present, chemical agents are usually used for treatment, but this treatment method not only easily leads to chemical residues, pollutes the environment, but also causes insecticide resistance and kills natural enemies, etc. Many problems, and the spraying of chemical pesticides is not conducive to the deep processing and utilization of neem, so the control of neem tortrix is ​​relatively difficult

[0004] At present, the research on the neem tree tumbler is mainly related to the law of harm, and there is no research report on its sex pheromone
