马尾松毛虫是我省最主要、危害最严重的森林害虫。解放后,特别是近几年来,大别山、大洪山的低山丘陵地区及鄂西北部分山区有30多个县,均有不同程度的危害,被害面积在150—200万亩左右。1964年被害面积发展到300多万亩,1965年上半年虫害更为严重,被害面积达500多万亩,比1964年同期扩大将近一倍。严重影响林业生产。因此,大力防治松毛虫,是我省当前林业生产上一项极为重要的任务。
Masson pine caterpillars are the most important and most harmful forest pests in our province. After the liberation, especially in recent years, more than 30 counties in the Dabie Mountains, Dahongshan hilly areas and parts of northwestern Hubei have different degrees of harm, with the victimized area of about 150-200 million mu. In 1964, the area harbored an area of more than 3 million mu. In the first half of 1965, pests were even more serious with the area of more than 5 million mu being harmed, nearly double that of 1964. Seriously affect the forestry production. Therefore, the vigorous prevention and control of pine caterpillars is an extremely important task in our province’s current forestry production.
