【摘要】 双条杉天牛Semanotus bifasciatus(Motschulsky)是危害我国重要绿化树种侧柏的重要害虫。通过室内饲养观察及野外调查相结合的方法,观察分析双条杉天牛的各虫态历期、生活习性和发生规律,并得到出蜇率与温湿度的相关性,及在不同的温度条件下,该虫对颜色有不同的趋性,但总体而言,对绿色有较强的趋性,对无害防治具参考价值。更多还原

【Abstract】 Semantus bifasciatus (Motschulsky) is an important woodborer attacking cupress, Platycladus orientalis in China. Both field and laboratory observations were conducted study its biology. There is close relationship between the occurrence of S. bifasciatus and relative humidity while the beetle demonstrated different tropism to color at different temperature with green color being the most sensitive to the beetle which may have some implications in managing this important beetle.更多还原
