| 摘 要： | 本文对思茅新木蛾Neospastis simaona Wang幼虫的取食行为、取食偏好性以及明暗条件对其取食量的影响进行了观察研究,为该昆虫的防治提供了理论依据。研究结果表明:思茅新木蛾幼虫随着龄期的增加,取食次数增多,取食总时间增加,但一次取食时间无明显变化;思茅新木蛾幼虫对木荷(Schima superba)有强烈嗜食性,4龄幼虫喜食木荷幼叶,5、6龄幼虫对木荷幼叶、成熟叶无明显偏好性;明暗条件对思茅新木蛾4至6龄幼虫的取食量没有显著影响(P>0.05)。

| Abstract: | The feeding behavior and feeding preference of Neospastis simaona Wang larvae was studied, including the effect of the light or dark conditions on food consumption. The results showed that the mean frequency and the total time spent on feeding increased with instar, whereas the time spent on each meal did not. N. sirnaona larvae preferred the leaves of Schima superba. The 4th instars preferred young leaves but the 5th and 6th instars did not display a preference between young and old leaves. Light or dark conditions did not influence food consumption of the 4th-6th instars （P 〉 0. 05）. |
