玉米螟赤眼蜂

玉米螟赤眼蜂适宜生境的研究与利用：Ⅲ.夏玉米间作匍匐型绿豆对赤眼蜂的增诱作用及其在穗期玉米螟防治中的利用

Study on the preference habitat of Trichogramma ostriniae : ⅲ . the attraction and augmentation function of summer corn interplanted with creeping type mungbean for the parasitoid and its application in Asian corn borer control at ear stage of corn

结果表明，玉米螟赤眼蜂在羽化初期（0~3h），卵巢中只有部分卵处于成熟状态，随着雌蜂年龄的增加，其抱卵量不断增加，至72h时接近其卵巢容纳量。

The results showed that only a fraction of mature eggs were observed in ovaries at the early stage after emergence , however , egg load increased as the female age increased and almost corresponded to ovary storage capacity by 72 h of adult life .

结果表明，在距释放点1～6m范围内，玉米螟赤眼蜂主要在2m范围内扩散飞行，少量个体可扩散4～6m远，这种扩散是渐进的、不连续的。

The results showed that within a distance of 6 m from the release point , it flied and dispersed mainly in 2 m range , while only a few individuals had dispersed as far as 4 - 6 m. The dispersal advanced gradually and intermittently .

玉米螟赤眼蜂的日活动节律受温度影响，低于18℃时赤眼蜂基本不活动，高于20℃时活动趋盛。

Its daily activity rhythm was affected by temperature , and was inactive below 18 ℃ and active over 20 ℃ .

结果表明，玉米螟赤眼蜂雄蜂在羽化时或羽化后很短的时间内其精巢就已发育成熟，成虫期不再形成新的精子。

The results showed that spermary of T.ostriniae had been set before the eclosion and no sperm was produced in the adult stage .
