沙雅县香梨园和核桃园4种食心虫成虫种群消长动态研究
Research on the Population Dynamics of Four Species of Fruit Borer Adults in Fragrant Pear and Walnut Orchards in Xayar County
摘要
Abstract
Based on a systematic monitoring in walnut and fragrant pear orchards in Xayar County,Xin-jiang,this study employed sex pheromone traps and sugar-vinegar solution traps to reveal the adult popula-tion dynamics of the codling moth(Cydia pomonella),the oriental fruit moth(Grapholita molesta),the plum fruit moth(Grapholita funebrana),and the peach fruit moth(Carposina sasakii).The results indi-cated that the oriental fruit moth(G.molesta)was absolutely the dominant species,with four generations per year and significant generational overlap.The codling moth(C.pomonella)had three generations per year,while both of the plum fruit moth(G.funebrana)and the peach fruit moth(C.sasakii)had two generations per year.The mixed-cropping orchard pattern significantly promoted pest populations:in mixed walnut orchards,the number of peach fruit moths increased by 81%,plum fruit moths by 44%,codling moths by 23%,and oriental fruit moths by 27%compared to monoculture orchards.In mixed fragrant pear orchards,peach fruit moths increased by 64%,plum fruit moths by 29%,codling moths by 40%,and oriental fruit moths by 6%.Meanwhile,in mixed orchards,the peak emergence periods for each generation of pests generally advanced by 5-9 days,thus extending the damage period and exacerbating the risk of generational overlap.关键词
