摘要
通过对青菜田节肢动物群落调查和时间生态位的测定,共记录节肢动物22个物种,其中植食性害虫14种、捕食性昆虫2种、寄生性昆虫4种、蜘蛛2种。小菜蛾、黄曲条跳甲、桃蚜、南美斑潜蝇为青菜田优势害虫,青翅蚁形隐翅甲、菜蛾绒茧蜂、蚜茧蜂和草间小黑蛛为青菜田优势天敌。还分析了群落中主要物种的时间生态位,探讨了主要害虫和天敌的相互作用关系及天敌保护措施。
A investigation on the arthropod community and its temporal niches was carried out in Brassica chinensis L. Fields from April to May, 2001. 22 species of arthropod were collected,of which there were 14 species of insect pests, 2 species of insect predators, 4 species of prositoids and two species of spiders. Plutella xylostella (Linnaeus), Phyllotreta striolata (Fabricius), Myzus persicae (Sulzer) and Liriomyza huidobrenisis (Blanchard) were the dominant insect pests. Paederus fuscipes Curtis, Cotesia plutellae Kurdjumov, Aphidius avenae Haliday, Erigondium grarminicolum (Sandevell) were the dominant nature emenies. The temporal niches of the dominant species were analyzed, the relationship between the dominant insect pests and nature enemies and the measures for nature enemy protection were discussed.
