摘要: 为研究稻-棉邻作系统稻田和棉田地表捕食性天敌丰富度和多样性,采用陷阱诱捕法对邻作稻田-棉田地表的捕食性天敌进行了系统调查,应用群落特征参数等对陷阱诱集物种群落、物种丰富度和多样性指数进行了比较分析。结果表明:稻-棉邻作系统共诱集3纲11目33科8532头样本。其中,稻田陷阱收集到8目27科35种5878头个体,捕食性天敌物种丰富度、多样性指数和均匀度分别为1.8779、0.7297、0.2576;棉田陷阱收集到3纲9目28科35种2654头个体,捕食性天敌物种丰富度、多样性指数和均匀度分别为2.4771、0.8041、0.4149。稻-棉邻作系统捕食性天敌有3纲3目13科17种5971头,优势种为捕食性天敌狼蛛,泽蛙是次优势天敌功能团,捕食性的鞘翅目天敌瓢虫类、步甲等种类多样性丰富。

Abstract: The pitfall trapping method was used to systematically investigate the abundance and diversity of the predatory natural enemies in rice and cotton adjacent plantation. The species community, species abundance and diversity index were compared and analyzed. The pitfall traps caught a total of 8532 specimens, which were classified to 33 families, 11 orders, 3 classes. The traps in rice paddy collected 5878 individuals, which were from 35 species, 27 families, 8 orders, and among which the species richness index, Shannon-Wiener diversity index and evenness index of ground predators were 1.8779, 0.7297 and 0.2576, respectively. The traps in cotton fields collected 2654 individuals, which were from 35 species, 28 families, 9 orders, and among which the species richness index, Shannon-Wiener diversity index and evenness index of ground predators were 2.4771, 0.8041, and 0.4149, respectively. A total of 5971 individuals of ground predators were collected in the rice-cotton adjacent planting fields, which belong to17 species, 13 families, 3 orders, and 3 classes. The most dominant predator species is the most abundant spiders (Arachnids) and the second dominant predator species is rice field frog Rana limnocharis, while the predatory Coleopteran natural enemies, including ladybugs and ground beetles, are characterized by high species diversity.

Key words: rice-cotton adjacent planting, predator, diversity, abundance
