摘要
研究了松褐天牛成虫对马尾松和湿地松不同龄级枝条的取食情况,结果表明:取食马尾松的松褐天牛成虫日平均取食量为196.6mm2.头-1.d-1,主要取食一年生枝条;取食湿地松的成虫日平均取食量为163mm2.头-1.d-1,主要取食二年生、多年生枝条和产卵木,较少取食一年生枝条。在选择取食的情况下,松褐天牛成虫主要取食马尾松,并且以一年生和二年生枝条为主,对湿地松的取食量较少。
Studies on feeding habit of adult Monochamus alternatus with four kinds of feeding materials of Pinus massoniana Lamb and Pinus elliottii Engelm were conducted in Anfu, Jiangxi Province in 2007. Results showed that adults consumed 196.6mm^2 of Pinus massoniana, one year twig got the largest feeding volume, and consumed 163mm^2 of Pinus elliottii, one year twig got the smallest. Adults fed significantly larger on Pinus massoniana twigs than they did on Pinus elliottii twigs when put them together.
