Torymus sinensis Kamijo(Hym.:Torymidae)是栗瘿蜂的专性寄生蜂,已知分布于我国的11个省(市、自治区)且在多数地区是栗瘿蜂的寄生蜂类群中的优势种。一年一代,生活史与栗瘿蜂吻合性极好。春天在寄生蜂类群中羽化最早,初孵幼虫具共寄生和过寄生现象,适当的加温可使越冬幼虫提早数月恢复发育。老熟幼虫形态特殊。幼虫期具4种重寄生蜂,即Decatoma concinna(Boh),Decatoma sp., Eupelmus urozonus Dalman,Ormyrus sp.。在我国分布的北限地区(如丹东),冬季低温可致越冬幼虫大量死亡。
Torymus sinensis Kamijo (Hym .: Torymidae) is an obligate parasitozoa of the gallnut bee, which is known to be the dominant species in 11 provinces (municipalities and autonomous regions) of our country and is the dominant species of parasitozoan beetle in most areas. One generation, life history and chestnut bees very good fit. In spring, the parasitoid was the first to emerge in the parasitoid group. The newly hatched larvae had the phenomenon of co-parasitism and parasitism. Appropriate heating could recover the overwintering larvae several months earlier. Mature larvae special shape. The larvae have four kinds of parasitoid bees, namely Decatoma concinna (Boh), Decatoma sp., Eupelmus urozonus Dalman, Ormyrus sp. In the northern limits of China (such as Dandong), winter low temperature can cause large numbers of overwintering larvae to die.
