Description

technical field [0001] The invention relates to the field of pest control, in particular to a sexual attractant for the pear borer moth, a lure core and a preparation method and application thereof. Background technique [0002] Fruit borer pests are important pests in fruit tree production, seriously threatening peach, pear and other industries. The small pear borer (Grapholitha molesta) is the most important fruit borer pest in my country. It can produce 3 to 4 generations in one year, and only in Zhejiang Province, the damage area to fruit trees reaches 2 million mu. The damage presents the following two characteristics: 1.

To the core, the fruit is deformed, which directly affects the quality and yield of the fruit; second, the fruit-boring pests are very difficult to control, and it is difficult to achieve the desired effect afte...

AI Technical Summary

Problems solved by technology

Chemical control Since the fruit-boring pests drill into the fruit, it is difficult for insecticides to directly contact the pests, and the application effect is often very unsatisfactory

This will inevitably lead to the frequent and excessive use of chemical pesticides by fruit farmers, which in turn leads to the emergence of pest resistance, and the problems of food safety and ecological security are particularly prominent; agricultural control mainly includes measures such as scraping bark, cutting tips, and bagging. Manually, the efficiency is low, the labor intensity is high, and it cannot adapt to the current large-scale and intensive production requirements. It consumes a lot of manpower, material resources and financial resources, and increases the burden on fruit farmers. Sex pheromone seduction effect is not obvious
