不同海拔高度松阿扁叶蜂生物学特性研究

Study on Biological Feature of Acantholyda Posticalis Matsumura at Different Altitudes

调查了松阿扁叶蜂在山东省徂徕山海拔320m和915m处发生的情况,结果表明:不同海拔高度该虫均为1年发生1代,以老熟幼虫越夏越冬;但在不同海拔高度条件下该虫各虫态发生期不同,低海拔320m处各虫态的发生期要比高海拔915m处提前10d左右。

This paper investigates the occurring rules of Acantholyda posticalis respectively at 320m and 915m in Mount Culai. The results show that A. posticalis will occur one generation a year no matter which altitude they live, and over--summering and winter with mature larvae in the soil. However, A. posticalis at different altitude have different occurring peroids. The results show that various developmental stages of A. posticalis advance about 10 days at low altitude than at high altitude.
