黄板诱集法取样下稻田节肢动物群落组成分析

Analysis of Arthropod Community Composition in Paddy Fields by Yellow Board Trap Sampling

采用黄板诱集法,研究了有机稻田和化防稻田节肢动物群落的基本组成。在有机稻田内,共查得节肢动物143种,分属于79科,其中植食类31科,捕食类15科,寄生类17科,中性类16科;在化防稻田内,共查得节肢动物94种,分属于58科,其中植食类21科,捕食类10科,寄生类15科,中性类12科。植食类、捕食类、寄生类和中性类在有机稻田的相对丰盛度分别为0.4412、0.0434、0.3408、0.1747,在化防稻田的相对丰盛度分别为0.5546、0.0266、0.2173、0.2014。上述结果表明在黄板诱集法取样下,植食类和寄生类是稻田节肢动物群落的主要成分。

We studied the basic composition of arthropod community in organic and chemical-control paddy fields by means of yellow board trap sampling. There were 143 arthropod species in organic paddy fields,they belonged to 79 families,and the family number of phytophages,predators,parasitoids and neutralities reached 31,15,17 and 16 respectively; ninety-four arthropod species in 58 families were found in chemical-control paddy fields,and the families of phytophages,predators,parasitoids and neutralities reached 21,10,15 and 12 families respectively. The relative abundance of phytophagous,predatory,parasitic and neutral arthropod in organic paddy fields was 0.4412,0.0434,0.3408 and 0.1747 respectively,while that in chemicalcontrol paddy fields was 0. 5546,0. 0266,0. 2173 and 0. 2014 separately. In conclusion,phytophages and parasitoids were the main compositions of arthropod community in paddy field under the condition of yellow board trap sampling.
