| 摘 要： | 经用P~(32)每毫升25量μci的剂量标记松毛虫赤眼蜂,室内测定P~(32)放射性强度:50头成蜂为466～642cpm,20粒柞蚕卵为109—117cpm。P~(32)标记对成蜂寿命、繁殖力、性比均无不良影响。苹果园P~(32)标记放蜂表明:苹果小卷叶蛾的卵块寄生率达96％,即粒寄生率93.09％。在寄生卵块中有73.91％的卵块测出P~(32),平均每块的放射性强度为14.34cpm,说明是人工释放的效果。有26.09％的寄生卵块未测出P~(32)或很弱,此为自然赤眼蜂所寄生。

| Abstract: | Mass reared T. dendrolimi was labelled with P32 at a dosage of 25 uci per ml. The intensity of radioactivity was detected in the laboratory as 466-642 cpm for 50 adult wasps and 109-117 cpm for 20 parasited oak silkworm eggs. The radioisotope label was found to have no adverse effect on the longevity, reproductivity, and sex ratio of the parasitoid. A 96% of egg mass parasitiza-tion and 93.09% egg parasitization of A. orana were found in the orchard. Based on the detected radioactivity, 73.91% of the egg mass parasitization were attributed to the mass released (P32 labelled) T. dendrolimi, while 26.06% were by naturally occurred Trichogramma. |
