摘要
杨小舟蛾是一种危害杨树的主要害虫。为有效控制杨小舟蛾危害,降低虫口基数,开展了野外林地和室内不同土壤湿度对杨小舟蛾蛹羽化及存活的影响研究。结果表明,降雨所造成的土壤湿度变化对杨小舟蛾蛹羽化和存活有显著影响,降雨量的多少,是影响杨小舟蛾羽化存活的重要条件之一。土壤湿度越大,杨小舟蛾蛹羽化和存活率越低;土壤湿度越小,杨小舟蛾蛹羽化和存活率越高。
The micromelalopha troglodyta is a major pest of harm poplar. In order to effectively con trol micromelalopha troglodyta damage, reduce the population base, we have carried out the influence study of the wild woodland and different soil moisture indoors on micromelalopha troglodyta pupae emer gence and survival. Resuhs show that soil moisture change caused by rainfall on micromelalopha troglody ta pupae emergence and survival has significant affect; the amount of rainfall is one of the important con ditions to affect micromelalopha troglodyta emergence and survival. The greater the soil moisture, the lower micromelalopha troglodyta pupae emergence and survival rates; and vice versa.
