| 摘 要： | 对沈阳地区梨象甲（Rhynchites foveipennis Fairmaire)在田间的发生规律进行的研究结果表明，在沈阳地区，梨象甲绝大多数一年发生1代，以成虫越冬；极少数个体两年1代，以幼虫越冬，越冬成虫4月末开始出土，5月中旬达盛期。成虫翌日出土量与降水呈正相关，出土始期决定于4月下旬的降雨时间。与献结果一致。卵发生始期为6月上旬，盛期为6月中旬-7月中旬，幼虫脱果盛期在7月末-8月上旬，化蛹始期为8月初，盛期为9月上旬-9月中旬。其中卵发生期，幼虫脱果时间及化蛹时期在沈阳地区为首次研究。

| Abstract: | The study on Bionomics and occurrence in orchard of Rhynchites foveipennis Fairmaire was conducted.The results showed that,almost of them have 1 generation evry year and pass winter in adult in Shenyang,while others have 2 generation and pass winter in larvae.The adult that passed winter appears at the end of April,and the peak in mid May.The period of adult occurrence was related to rainfall, in the all period r=0.6305 and before the flourishing period r=0.8141.The egg appears in the first 10 days of June,the fourishing period is from mid June to mid July.Most larvae leave the pear around the end of July.The pupa appears during August and September. |
