摘要: 2016—2018年,利用性信息素诱集方法对江苏省句容市桃园梨小食心虫、桃小食心虫和桃蛀螟的种群动态进行了研究。结果表明,种类间以梨小食心虫、年度间以2016年诱捕量最多。梨小食心虫以2016年、2017年发生量大,峰次多,但越冬代成虫发生量远远低于2018年。桃小食心虫9月上旬后几乎不发生。桃蛀螟2018年种群数量远高于2016年和2017年,峰次多,发生期一直持续到11月上旬。3年间,3种害虫的年均月诱捕量与年均月降雨量均无明显的线性关系(P>0.05);年均月诱捕量与年均月温度总和仅桃小食心虫表现为显著正相关(P<0.05)。

Abstract: The sex pheromone inducing methods were used to study the population dynamics on Grapholitha molesta(Busck), Carposina sasakii Matsumura and Conogethes punctiferalis from 2016 to 2018 in Jurong City, Jiangsu Province. The results showed that the number of Grapholitha molesta among species was the largest in 2016. The large generation and the number of peaksin Grapholitha molesta both appeared in 2016 and 2017, however, the overwintering adult was much lower than the generation in 2018. Carposina sasakii occurred rarely after early September of each year. Compared with 2016 and 2017, the population of Dichocrocis punctiferalis was the highest in 2018, which showed occurrence periods lasted until early November. There were no significant linear relationships between annual average monthly quantity of trapped insects and annual average monthly precipitation in the three pests during 2016-2018 (P>0.05). There was significant positive correlation between the annual average monthly quantity of trapped insects and the sum of monthly temperature in Carposina sasakii (P<0.05).
