摘要
通过在苹果园悬挂金纹细蛾性引诱剂,观测其发生量,并同时记录温湿度、风速、降雨量等气候因子,研究得出湿度与发生量呈显著相关。在3月份其越冬代发生比较整齐,数量少,是防治的重点时期。
Asiatic apple leafminer (Lithocolletis ringoniella Mats.)is an important pest being harmful to apple production in Luochuan counry, Shaanxi province. The occurrence capacity of Asiatic apple leafminer has been observed by using attractant in apple orchards, and the relationship between the occurrence capacity and meteorological factors has been analyzed. The results indicate that there is a significant relationship between the occurrence capacity and humidity. The occurrence of overwintering generation in March is quite coinstantaneous with a small population, when is the best period to control it.
