弄清冬季诸气象因素对越冬松毛虫的综合影响将有助于在大面积范围内预测越冬后不同地区松毛虫的残存虫口,节省大量的越冬后虫情调查用工。同时,掌握越冬松毛虫的减退规律后,将为划分松毛虫发生类型区和建立越冬代松毛虫防治策略提供理论根据。 本文根据江山县1985年冬至1986年春不同地理条件下,冬季主要气象因子的观察资
To understand the winter meteorological factors on the impact of winter pine caterpillars will help predict the large area of overwintering in different parts of the remaining caterpillars insect population, save a lot of winter insect investigation work. At the same time, grasping the rules of the decline of the wintering dendrolimus will provide a theoretical basis for the division of the type of dendrolimus and the establishment of control strategies for the overwintering dendrolimus. According to the different geographical conditions of Jiangshan County during the winter of 1985 to the spring of 1986, the observation data of major meteorological factors in winter
