Study on Community Structure and Dynamics of Insects in a Ragweed Protecting Habitat

采用大类群分类法对保护地豚草(Ambrosia artemisiifolia)与非豚草样地中昆虫的群落结构及动态进行了研究,结果表明,在大棚中共采集昆虫17科,属8个目,其蚁科占绝对优势(占昆虫总量的66.35%),其次是蚜科(16.28%)。豚草地昆虫群落<半豚草地昆虫群落<非豚草地昆虫群落;因昆虫的种群差异,在不同样地的数量存在明显差异;随着季节的推移,昆虫群落先增后减,8月份达到最高峰。

Macro-group classification method was used to study the community structure and dynamics of insects in a ragweed the habitat. Results showed that 17 families of soil insects belonging to 8 orders were collected in the habitat. On the level of families, the individual number of Formicidae was absolutely dominant (amounting to 66.35% of the total individual number of insects), followed by Aphididae (16.28%). the community of insects in ragweed plot<in non-pure ragweed plot<in control plot; the number of individual insects were different obviously due to family differences; the number of insect community increased and then decreased with the proceeding of growth season and achieved the maximum value in August.
