Release-controlled preparation for simultaneously interfering pest mating and attracting beneficial insects and application

Abstract

The invention provides a release-controlled preparation for simultaneously interfering pest mating and attracting beneficial insects. The release-controlled preparation comprises pheromone for interfering the pest mating and an attractant for attracting the beneficial insects. The release-controlled preparation has the advantages that the release-controlled preparation is released into the surrounding environments in a gas form, so as to interfere the mating of the target insects in the effective stage, and attract the beneficial insects, such as bees; more importantly, the release rate of thepheromone for interfering the mating and the release rate of the attractant for attracting the target insects are different, so as to ensure that the different volatiles can complete the respective functions in the same carrier at different stages.

Description

technical field

[0001] The invention belongs to the field of agriculture, and in particular relates to a slow-release preparation for interfering with mating of pests and attracting beneficial insects, a preparation method and application thereof. Background technique

[0002] Codling moth and pear borer (Busck) are major pests of apples, pears and peaches. Codling moths are also not good for walnuts. They are parasitic on fruits (and nuts such as walnuts) and can lead to yield loss if not controlled.

[0003] The pheromone composition of certain pests, including codling moth in apples and pears and pear borer in peaches and pears, is well known and is widely used as a means of disrupting the mating of pests. This essentially uses the synthetic pheromones of these species to distract male moths trying to find females. If mating is delayed or completely prevented, fewer or no eggs are laid, the pest will be controlled and the crop will be protected. In fruit trees, pests ...
