AbstractTo achieve effctive prevention and control of Buzura suppressria on eucalyptus，this paper analyzed the occurrence characteristics and current situation of Buzura suppressaria on eucalyptus in Guangxi State-owned Sanmenjiang ForestFarm in 2O24，and putforward corrsponding control strategies.Theanalysis showed thatBuzura suppressaria had 3 generations per year in the study area，overwintering as pupae in the surface soil.The larvae were highly voracious，and the adults were activeatnightwith strong flying abilityand phototaxis.Buzurasuppressriacaused damageoveralargearea in the studyarea，Mayand Julywere the outbreak periods with severe damage;thedamagedtreeages were concentrated in middle-aged forests and near-mature forests，and the damage to eucalyptus sprout forests was more serious than that to seedling-plantedforests.Inviewof this，thefolowing controlmeasures were proposed： improving the monitoringsystem by setting up fixed monitoring points，constructing a“general farm + branch farm + base”monitoring network and implementing classified monitoring; implementing prevention and control by manuallydigging pupae，spraying Bacillus thuringiensis for prevention，and seting up insecttrapsand insecticidal lamps;optimizing forestland management by extending the tending periodand cultivating large-diameter eucalyptus timber;andconstructing ajointprevention mechanism bycarryingout popular science publicity and technical training on insect pests.This paper provides a reference for the comprehensive prevention and control of Buzura suppressaria on eucalyptus.
