Screening And Application Of Light Wave For Attracting Pests Of Carya Cathayensis

Carya cathayensis is a unique nut tree species in my country.It is a pillar industry in its main producing areas and an important source of income for local forest farmers.In recent years,with the rapid development of the Carya cathayensis industry,intensive management and large-area pure forest planting have led to the reduction of species diversity and stability of the Carya cathayensis forest ecosystem,and pests in the Carya cathayensis forest have become increasingly rampant,which has now become a limit to the development of the Carya cathayensis industry.The population composition of Carya cathayensis forest pest and effective control methods are important issues to be solved urgently.The Carya cathayensis in Lin’an was taken as the research object in this experiment,aiming at revaling the insect community structure of Carya cathayensis forest,exploring the growth and development dynamics of the main pests of Carya cathayensis,screening out the light source with better effect on Carya cathayensis forest,and summarizing the scientific lamps of Carya cathayensis forest.Methods,to explore the green control strategies of Carya cathayensis forest pests.The trapping effect of frequency-vibration insecticidal lamps of 6different frequency wavelength was compared by means of light trapping.The test results showed that a total of 19,226 insects were trapped,involving 102 species of 10 orders,42 families,and the trapped Carya cathayensis pests were concentrated in Coleoptera,Lepidoptera,Orthoptera and Hemiptera,and the trapped natural enemy insects mainly concentrated in the wide-ptera,Neuroptera.The trapping effect of each wavelength was significantly different.The trapping effect of the insecticidal lamp in the 365 nm wavelength was better than that of other wavelength,and the ratio of natural enemies was low,and the comprehensive control effect was the best.The best time to use lights to control Carya cathayensis pests is from June to September,and climate factors have no obvious effect on the amount of insects.In this study,it is believed that the 365 nm wavelength insecticidal lamp can be used to control the main underground pests and the main leaf-eating pests of Carya cathayensis.While controlling Carya cathayensis pests,the population dynamics of hickory pests can be detected and predicted,and other physical and chemical ecological control methods can be used to control Carya cathayensis pests.Comprehensive management can provide new ideas for the green control of Carya cathayensis forest pests.
