摘　　要：为研究长绿飞虱的为害规律,制定合适的防治策略。对不同温度下长绿飞虱成若虫蜜露分泌量和体质量变化进行研究,建立了若虫蜜露排放量与体质量的回归方程。结果表明,长绿飞虱低龄若虫及不同体色成虫在不同温度下蜜露排放量无显著变化,但其高龄若虫在高温条件下平均蜜露排放量显著升高;雌成虫体质量为雄虫体质量的2倍,雌虫体质量在26℃最高;除5龄若虫外,温度未对若虫体质量产生显著影响。各温度条件下长绿飞虱若虫日均蜜露排放量与其体质量呈显著正相关。长绿飞虱为害最严重时期为4~5龄若虫期,故田间防治长绿飞虱时期应选择在3龄及3龄以前,当田间温度较低时,可以考虑适当放宽长绿飞虱的防治指标。To study the damage regulation of Saccharosydne procerus(Mateumura),the honeydew secretion amount and body weight of adults and nymphs under different temperatures were measured,regression equation of body weight and honeydew secretion amount of nymphs was established.The results showed that honeydew secretion amount of low-instar nymphs and adults of different color had no significant change under different temperature,while honeydew secretion amount of nymphs increased significantly in 4 th-5 th instar.The body weight of female adults was twice of that of male adults.And the body weight of female adults reached the highest under 26℃.Temperature had no significant influence on the body weight of nymphs except 5 th instar.Honeydew secretion amount showed a significant positive correlation with body weight under different temperature.4 th-5 th instar was the most serious damage period.Therefore,the suitable period for control should be 3 rd instar and before.When the temperature is low,the requirements of control can be reduced properly.
