实验水池是评价杀虫剂效应和安全性的重要场所，水池中无脊椎动物群落结构和种群动态是评价杀虫剂的基础资料和考核指标。本文报告１９９２年至１９９３年在美国佛罗里达中部地区对应用于杀虫剂评价的实验水池中昆虫与其它无脊椎动物群落结构及其优势种的种群动态研究结果。用羽化诱捕、勺舀、网拉及挖取底物法，从实验水池中共采到昆虫与其它无脊椎动物５０余类。其中，羽化诱捕到的昆虫中摇蚊占９３．９％，蜉蝣目昆虫占４．６％，莹蚊占１．５％；水面勺舀采样所获昆虫中，半翅目占６２％，鞘翅目占１４．６％，双翅目占１２．１％，晴蜓目占４．９％，其它无脊椎动物占６．４％；网拉法所获其它无脊椎动物中，轮虫占４６．８％，桡足类占４１％，枝角目类占１２％；挖取底物法所获无脊椎动物中，线虫占５３．７％，摇蚊幼虫占３６．９％，其它占９．４％，优势种的变化与池中水深、ｐＨ以及氧含量的季节变化有关。
The experimental pond is an important place to evaluate the insecticide’s effect and safety. The structure and population dynamics of invertebrate in the pond are the basic data and evaluation index for evaluating the pesticide. This article reports the population dynamics of insects and other invertebrate communities and their dominant species in experimental ponds used in pesticide evaluation from 1992 to 1993 in central Florida, USA. With the feather trap, spoon scoop, net pull and dig the substrate method, collected from the experimental pool of insects and other invertebrates more than 50 categories. Among them, eclosion trapped insects accounted for 93.9% of Chironomidae, Pitynotes insects accounted for 4.6%, Ying Ying accounted for 1.5%; water spoon scoop samples collected insects, Hemiptera accounted for 62%, Coleoptera Accounting for 14.6% of the total, Diptera accounted for 12.1%, the glaucous species accounted for 4.9%, other invertebrates accounted for 6.4%; net pull Law obtained in other invertebrates, rotifers accounted for 46 .8%, Copepoda accounted for 41%, branches class accounted for 12%; digging substrate method was obtained in invertebrates, nematodes accounted for 53.7%, chironomid larvae accounted for 36.9%, others accounted for 9 .4%. The change of dominant species was related to the seasonal variation of water depth, pH and oxygen content in the pond.
