摘要
本文报道辐照棉铃虫与正常棉铃虫精子传导。棉铃虫的精子传导是一个复杂的过程 ,正常棉铃虫精子传导的失败率为 1 9% ,经 2 50Gy和 40 0Gy辐照后 ,精子传导的失败率分别为 2 1 %和 50 %。精包“帽”定位的异常是精子传导失败的一个重要原因。当棉铃虫雌虫与高剂量辐照雄虫交配后 ,产卵反应表现异常。
Transmissions of sperm by unirradiated and irradiated cotton bollworm, Helicoverpa armigera, were studied by live dissection of females immediately after the initiation of mating.In cotton bollworm the sperm transfer was rather a complex process.In fact unirradiated males failed to transfer sperm in about 19% of their matings.When irradiated with 250Gy and 400Gy,aberrations of sperm transmission were about 21% and 50% respectively.The failure of spermatophore “cap” location was an important reason of sperm transmission aberrations.When females mated to high\|dose\|irradiated males,their oviposition response appeared abnormal.
