摘要

<正>马尾松毛虫幼虫的粪粒数量与大小,是随着世代的不同以及同一世代的不同龄期而有规律地变化。利用幼虫地面的落粪数量,来推算高大树上虫口密度,简便易行,准确可靠。

Abstract

In a systematic study on the Lishui Forestry Farm, Jiangsu province from 1983 to 1986, it was found that feces amount of pine caterpillar (Dendrolimus punctalus Walker) varied regularly with different ages of different generations and that feces amount of pine caterpillar could easiely and reliably be used to accurately determine insect density in high and big trees which are difficult to investigate.
