芦苇钻心虫Archanara aerata Butler在江苏省金湖县一年发生一代,以卵滞育越夏越冬。卵的耐寒性很强,不同时期的越冬卵,其耐寒性有显著的差异。卵的耐水性也很强。幼虫共4龄,3龄幼虫有转株危害的习性。不同地势、不同类型滩地幼虫的发育进度不同,高滩的发育进度比淹水的快。老熟幼虫在芦苇的茎秆中化蛹。成虫趋光性不强,产卵于芦苇枯黄叶鞘的内侧。 影响芦苇钻心虫发生量的主要因素是天敌。影响其发生期主要是温度。 烧滩和药剂防治相结合是有效的防治措施。烧滩的防治效果为96.44％。小区药剂防治试验表明,1:200倍的25％杀虫双水剂,1:2000倍的40％氧乐果乳剂和1:1000倍的40％杀虫灵乳剂防治效果均较好。
Archanara aerata Butler occurs in Jinhu County, Jiangsu Province, a generation a year, winter to egg diapause overwintering. The cold resistance of eggs is very strong, overwintering eggs in different periods, there are significant differences in cold tolerance. Water resistance of eggs is also very strong. A total of 4 larvae, 3rd instar larvae have the habit of strain damage. Different terrain, different types of beach larvae development progress is different, high beach progress faster than flooding. Mature larvae pupate in the stalks of reeds. Adult phototropism is not strong, spawning in the reed leaves inside the yellow sheath. Affect the occurrence of reed borer is the main factor in natural enemies. Affect its occurrence is mainly temperature. Combining burning beach and pharmaceutical control is an effective control measures. Burning beach control effect of 96.44%. Community pharmacy prevention and control tests show that 1: 200 times 25% insecticide Shuangshui, 1: 2000 times 40% of the omethoate and 1: 1000 times 40% insecticidal emulsion control effect is better.
