阿拉尔地区水稻花蓟马发生动态及监测方式

The Occurrence Dynamic and Monitoring Methods of Frankliniella intonsa(Trybom)on Rice in Alar Region

2015—2019年在阿拉尔地区水稻田对花蓟马的发生情况开展监测,结果发现:花蓟马种群5月上中旬在水稻田间出现,7月中、下旬种群数量迅速上升,8月为高峰期,9月下降;蓝色粘虫板诱集花蓟马效果更好,黄色粘虫板效果较差;7、8月有效积温和当月虫量之间有相关性,也可作为花蓟马种群动态监测的参考因素。

From 2015 to 2019,the occurrence of Frankliniella intonsa(Trybom)was monitored in the rice fields of Aral region.The results showed that the population of Frankliniella intonsa(Trybom)appeared in the rice fields in the middle of May,and the population increased rapidly in the middle and late July,it peaked in August and decreased in September.blue group sticky card had the better effect on trapping Frankliniella intonsa(Trybom)than yellow one.There was a correlation between the accumulated temperature in July and August and the number of insects in the same month,which could also be used as a reference factor for monitoring the population dynamics of Frankliniella intonsa(Trybom).
