粘虫赤眼蜂(Trichogramma leucaniae)在山西主要分布于中部平川地区,沿汾河等河流的两岸低洼下湿谷田,一般海拔在800～900米左右,高山及丘陵地不易发现。在粘虫第一代发生期,田间未发现该蜂。第二代卵期,自然寄生率一般为4.8～5.5％,高的可达8％。 该蜂可以在麦蛾、棉铃虫、棉大卷叶螟、柳毒蛾等卵内寄生。按蜂卵比1:1～1:3接蜂,寄生率分别为45.5、24、18.5和45.3％;但用柞蚕及蓖麻蚕卵等大卵繁蜂时则不易成功。在寄主卵上涂粘虫卵液与蜜糖液后接蜂,寄生率较对照有所提高。
Trichogramma Trichogramma (Leucaniae) is mainly distributed in Pingchuan area in Shanxi Province. Along the banks of Fen River and other rivers, low-lying wet valley fields are generally located at altitudes of 800-900 meters. Alpine and hilly areas are not easily found. The first generation of armyworm occurred in the field did not find the bee. The second generation of eggs, the natural parasitic rate is generally 4.8 ~ 5.5%, up to 8% high. The bee can moth, cotton bollworm, cotton leaf roller, Liuchuan moth and other eggs parasitic. According to the ratio of bee eggs to bee than 1: 1 ~ 1: 3, the parasitic rates were 45.5, 24, 18.5 and 45.3%, respectively. Turtle eggs in the host eggs coated with eggs and honey solution after the honey, the parasitic rate has increased compared with the control.
