摘　　要：为明确月季茎蜂在江苏省常州市内的发生规律,探索防控药剂的应用技术。结合本地区物侯规律调查月季茎蜂发生动态并用常规喷雾法开展田间试验,明确各药剂防治效果。调查结果显示,月季茎蜂在江苏常州1年发生1代,4月上中旬为雌虫产卵高峰,18~26℃温度条件下,晴天卵历期5~6d,阴天6~8d。1~3龄幼虫较为活跃,3龄幼虫后移动性逐渐变差。高龄幼虫一般在茎秆地下部分或较老茎秆内作茧越冬。田间筛选试验和农药登记试验表明,月季初见折梢时(一般4月中上旬)施用噻虫嗪67.5~90g/hm^(2)1次,防效超过80%且对月季植株安全。噻虫嗪可作为防治月季茎蜂的优选药剂。This paper aims to study the occurrence pattern of Neosyrista similis in Changzhou,Jiangsu and to explore the application technology of control agents.A field experiment was conducted to investigate the dynamics of the occurrence of the local Neosyrista similis in Changzhou City,Jiangsu Province,using conventional spraying method.The results of the survey showed that the Neosyrista similis occurs once a year in Changzhou,Jiangsu,with the egg laying by females adults in early-mid April.At the temperature of 18-26℃,the eggs hatch in 5-6 days on sunny days and 6-8 days on cloudy days.The 1-3 year old larvae are more active,while their mobility will gradually become lower in the later stages.The older larvae usually overwinter in the underground part of the stalks or in the older stalks as cocoons.The field screening trials and registration tests have shown that the field control effect of thiamethoxam on Neosyrista similis is higher than 80% after one application and safe to Rosa.Thiamethoxam can be used as a preferred pesticide for the control of Neosyrista similis in the field.
