| 摘 要： | 对越冬代竹螟点灯诱蛾量和第１代幼虫发生量的调查研究结果表明，竹织叶野螟从１９７９年占主要４种竹螟数量的８６．６８％下降到１９９１年的３２．１６％，竹金黄镰翅野螟和竹大黄绒野螟从１９７９年的３．０３％、７．５３％上升到１９９１年的４０．１３％和２６．４２％。６月中旬诱蛾量与幼虫发生量的直线方程ｒ＝５．７＋０．２ｘ（ｒ＝０．８１）达到极显著水平，可考虑应用于预测第１代幼虫发生量。

| Abstract: | Investigation on the amount of light-traped overwintering moths and the incidenceof the first generation larva indicated that the amount of traped Algedonia coclesalis moths in1979 was 86 .68%, but 32.16% in 1991 among four main insects; Cirfcobotys aurealis and Eumorphobotgs obsuralis was respectively 3. 03% and 7 .53% in 1979, but 40.13% and 26.42% in 1991.Linear function of traped amount of moths and incidence of larva in the middle June was r =5.7 0.2x (r = 0.81) which had evident difference and could be used to predict the incidence offirst generation larva. |
