江苏侧隆螽对马尾松毛虫的捕食作用

江苏侧隆螽具有个体大,食量大,活动范围广,发生早,捕食作用时间长等特点,是马尾松毛虫的有效天敌之一。1984～1986年,在室内进行了捕食者对不同虫态(龄期),马尾松毛虫的功能反应,测定了捕食者个体间的相互干扰作用及其对功能反应的影响,并建立了参数方程,能在一定程度上描述螽斯对马尾松毛虫卵,幼小幼虫及老龄幼虫的捕食作用。

PREDATION OF THE JIANGSU TETTIGONID TO THE MASSON'S PINE CATERPILLAR

The Jiangsu tettigonid, Allanicus kiangsu Ramme, is characterized by big size, great appitite, wide habitat, early occurence, and long predationtime. It Is one of the effective natural enemies of the Masson's pine caterpill-ar, Dendrolimus punctatus (walker). In 1984 to 1986 the functional reac-tion of the predators to various instars of the caterpillar was stduied, the int-erference of individual predators and their impact on functional reaction of thepredators were estimated, and a parameter equation was founded, which descri-bes in a certain degree the predation of the tettigonid to the eggs, young andold instars of the caterpillarl arvae.
