Dynamics and Characteristics of Grapholitha molesta in Tumxuk City
摘要
Abstract
[Objective]The occurrence dynamics of the Oriental fruit moth in orchards of Tumxuk City were monitored to investigate its population fluctuation,the duration of each generation,and to analyze the factors influencing the overlapping of its generations.This study aims to provide a basis for the forecast and precise green control of the Oriental fruit moth in local orchards.[Methods]The pheromone trapping technique was employed to monitor the adult occurrence dynamics of the Orien-tal fruit moth in different orchards in Tumxuk City over two consecutive years.[Results]In Tumxuk City,the initial eclosion period of overwintering generation adults occurred from March 20 to 26,with a concentrated occurrence period from March 22 to 25.The earliest initial capture was recorded in peach orchards.Throughout the year,adult populations exhibited five occur-rence peaks,which were largely consistent across different orchards:from late May to early June,late June to mid-July,late July to mid-August,and late August to early September.Significant generation overlap was observed between successive gen-erations.The mean durations from the peak of one generation to the next were:41.5 days from the overwintering generation to the first generation,33.25 days from the first to the second generation,40.75 days from the second to the third genera-tion,and 26 days from the third to the fourth generation.[Conclusion]The findings systematically elucidate the adult occur-rence dynamics and generational alternation pattern of the Oriental fruit moth in Tumxuk City,providing an important theoret-ical basis for the accurate prediction and green control of this pest in orchards.关键词
