This insect is a small Lepidoptera pest of the family Lepidoptera, and it is the most serious pest that harms plum fruit, often with a damage rate of 80% to 90%. Teardrop-shaped pectin flowed from the wormhole, and the injured fruit could not continue to develop and gradually turned purplish red and fell off. The path of the killed fruit insect is full of red insect dung, and the fellow-townsman called it "bean paste stuffing". Control methods: the key period for the control of plum heart borer is the peak period of adult and spawning of each generation and the burying period of the first generation of mature larvae. 90% trichlorfon 0.8% solution, 50% malathion 1% solution, 50% dichlorvos 0.8% solution. Before fruit drop, 50% phoxim 1%-1.5% solution was applied to the soil under the crown of Li Shu. At the end of falling flower (95% falling flower), when the small fruit has wheat grain size, spray the first time, with dichlorvos, enemy kill, quick kill, Lefuling can be sprayed every 7-10 days. From the point of view of comprehensive control, biological agents can be used for soil treatment under the canopy, such as Beauveria bassiana. The fallen fruit should be swept away after autumn to reduce the source of insects in the coming year.
