初步查明在陕西麦区寄生小麦吸浆虫的寄生蜂有12种。其中,寄生麦红吸浆虫(SitodiplosismoselanaGehin)的5种,寄生麦黄吸浆虫(ContariniatriticiKirby)的4种,2种吸浆虫均寄生的3种。寄生蜂具隔年出土习性。其田间羽化数量白天多于晚上。吸浆虫种群变动和农药使用是影响寄生蜂种群的2个主要因素。麦红吸浆虫寄生峰有2个高峰,第一峰紧随吸浆虫成虫高峰之后,第二峰在吸浆虫初龄幼虫期。麦黄吸浆虫寄生峰高峰只有一个,比吸浆虫成虫高峰晚2~4d。
Preliminary identification of parasitized parasitoids in Shanxi wheat area parasitized bee 12 species. Among them, 5 species of parasitized SitodiplosismoselanaGehin, 4 species of parasitism Contarinia tritici Kirby and 3 species of 2 species of Midazolam parasitized. Parasitic bees with habit of perennial unearthed. The amount of emergence in the field more during the day than at night. Midazolam population fluctuation and pesticide use are the two main factors affecting the parasitoid population. Myzus persicae parasitic peak peak has two peaks, the first peak immediately after inhalation of adults inhalation peak, the second peak in Central Plains first instar larvae. Apodemus malnutrition parasitic peak only one peak, adult Midazola late peak 2 ~ 4d.
