摘　　要：为阐明嘉兴市不同单植果园梨小食心虫发生规律与气象因子的相关性,采用性信息素诱捕器监测梨小食心虫虫口数量变化,利用Pearson积矩分析虫口变化与降水量、温度、日均光照时间等气象因子的相关性。结果表明,不同果园梨小食心虫发生规律存在差异,单植蜜梨园一年有6个高峰期,单植槜李园一年有7个高峰期。2个果园雄虫消长与温度呈正相关,达极显著水平,与日均光照时间及降水量均无明显线性关系。由此可见,通过追踪关键气象因子的变化一定程度上可为实现不同果园梨小食心虫种群数量监测提供参考依据。The purpose of the study is to elucidate the correlation of oriental fruit moth's(OFM)occurrence rules with meteorological factors.The adult OFM populations were monitored using sex pheromone traps in different orchards,and the correlation between increased number of OFM and meteorological factors(precipitation,temperature,average daily light duration)were analyzed by Pearson's correlation.The results showed that there were different occurrence index between mono-cultured pear orchard and zuili orchard.The adults of OFM had six and seven peak periods per year in above two different orchards respectively.The results of correlation analysis showed that the number of male adult OFM was significantly positively correlated with temperature in two orchards,while no correlated with daily light time and precipitation.Therefore,it can provide a reference basis for monitoring the population of OFM in mono-cultured orchards by tracking the changes of key meteorological factors partly.
