【摘要】 以样地实地调查方法调查了闽西地区引种树种翅荚木(Zenia insignis Chun)纯林昆虫群落结构。共记录到昆虫11目55科93种,其中鳞翅目、鞘翅目和直翅目为优势类群;中性昆虫占比在50%以上,植食性昆虫次之,捕食性昆虫种类和个体数均少于植食性昆虫,寄生性昆虫比例最低。分析结果表明,翅荚木纯林昆虫群落多样性高,各种类个体数量较均匀;群落中各种类具有较强的制约作用;天敌类群种数与植食性昆虫种数之比(Sn/Sp)相对较低。研究结果对于引种树种翅荚木的虫害防控具有重要意义。更多还原

【Abstract】 The method of sample investigation was carried out on the survey of insect community structure in pure introduced Zenia insignis Chun forest of western Fujian. In total of 93 species in 55 families,11 orders were recorded and the dominant groups were Lepidoptera,Coleoptera and Orthoptera. The number of families,species and individuals of neutral insects accounted for over 50%of the total,followed by herbivorous insect. The number of species and individuals of predatory insect was lesser than that of herbivorous insect,and the ratio of parasitic insect was the lowest. The results showed that the insect diversity in pure Z. insignis was high and the distribution of all species in individual number was even; the constraints in the number between different insect species was strong; the ratio of species of natural enemy insect and herbivorous insect( Sn/ Sp) were relatively low. The result had the important value on the pest prevention and control of introduced Z. insignis.更多还原
