摘要
随着城市人民生活水平的提高,人们对蔬菜品质的要求亦不断提高。由于蔬菜品种丰富,生长周期短,换茬频繁,害虫种类繁多,长期采用化学农药防治,农药的污染成了目前突出的问题,更严重的是有些生食的蔬菜农药污染,给人类健康直接带来了威胁。为此,近十年来,国际上对蔬菜害虫的防治采用了新的手段。
This is the first paper of the series on animal pests and their natural ene- mies in the vegetable fields in middle region of Shanxi province.It presents the results of the investigation on the cabbage field in 1984 to 1986. The investigated insect pests included 31 species,falling into 30 genra,20 families,8 orders of the class,INSECTA among which the most important spe- cies were Pieris rapae L.,Blutella xylostella(I.),Argyrogrammaagnats (Stau- clinger)and 3species of A Phididae named Rhonalosiphumpseudobrassicae Davis, Myzus persicae(Sulker),Brevicoryue brassicae(L.),Mamestra brassicae was a temporary one and Trips tabaci Lindeman was a secondary one. Forty nine species of the natural enemies belonging to 40 genera,25 families, 6 orders were collected,among which 3 species:Bterinakys puparum(L.), pnobocampe sp.and Apauteles flavipes(Cameron)were considered to play an important role in controlling the above pests. About 33 species of 10 families of spiders collected seemed to be important in controlling the damaging insect pests,but among which the predominant ones were paradosa T-insiqnica,philodromus cespitum walckemaer and Misume- nopd tricuspidatus(Fabricius).
