| 摘 要： | 松突圆蚧(HemiberlesiapitysophilaTakagi)是松类的重要检疫性害虫。文中以福建某试验地松林为研究点,对松突圆蚧的生物学特性进行了系统观察研究。4～7月份是虫口密度最大、危害最严重的时期。松突圆蚧有完整的生活周期即有有性世代,每雌平均产卵量为93粒,林间自然雌雄性比为2 05∶1。1a发生4代,世代重叠。

| Abstract: | Hemiberlesia pitysophila Takagi is an important quarantined defoliator of pine.The study the pest was carried out systematically in the Fuqing District's pine forest.The sexual generation of the pest was observed for the first time,that show Hemiberlesia pitysophila Takagi has a complete life cycle.Population occurs as full-grown at during April to June.Female adult oviparity 93 eggs averagely in life cycle,the sex ratio is 2.05∶1 in nature.Environment and it's host effect very much at the insect's density of forestry specially north-eastern wind effect more.The pest can at most have four generations per year in Fuqing District.The phenomenon of generation overlapping is common. |
