The invention relates to the technical field of forest fruit pest
trapping and monitoring, and discloses a morus laevigata longicorn
trapping method which comprises the following steps: S1, compounding a polar
solvent with acetic esters, methylsalicylic acid,
green leaf smell components, monoterpenes and morus laevigata
branch and leaf
essential oil according to a preset formula to form homologous and damage and
diffusion enhanced three types of
signal windows, the host smell
simulation trapping agent is obtained. The method comprises the following steps: locking a characteristic host
odor formula of morus laevigata according to
insect conditions, weather and phenological data in the early stage of adult occurrence, preparing a trapping agent containing homologous, damaged and diffused enhanced signals, and combining a dual-channel slow-release lure, a phase-change controlled-release material, a garden edge leading-away belt along the main
wind direction and sparse monitoring
layout in a garden; and a trapping field which is still stable in a high-temperature season is formed by windward hanging on a tree crown, so that the effects of improving the female long-fruit mulberry
longhorn beetle interception capability, inhibiting the release rate from being out of control, and reducing the fluctuation of a capture curve and the occurrence level of fresh worm holes and oviposition marks in a garden are achieved.
