摘要
采用(32)~p标记法研究了辐射不育小菜蛾的扩散能力。试验表明,10天内,不育小菜蛾有94％扩散在40m范围内,极个别可达120m,而在这10天中,后3天的诱捕虫数平均每天仅占总诱捕虫数的0.5％,说明辐射不育小菜蛾的扩散有一定期限,3天内扩散范围约700m^2。
This paper reports the spread ability of the radiation steriled diamo-ndblack moth ( DBM) .It shows that the 94.2% of DBM is spread in 40m duration of 10 days and a few of moths are 120m. It indicates that the spread of steriled DBM is definitely time limit, the spread area is within ca. 700m2 in the first three days.
