| 摘 要： | 室内实验表明 ,高温 ( 4 0～ 48℃ )处理 2h对南美斑潜蝇LiromyzahuidobrensisBlanchard各虫态均有较强的致死作用 ,其杀伤力随温度升高而明显提高 ;45℃对各虫态的校正致死率均在 90 %以上 ;48℃时 ,对各虫态校正致死率均达 1 0 0 %。田间试验结果表明 ,高温闷棚 ( 4 0～ 48℃ )对幼虫、蛹、成虫的防效分别达 86 4% ,88 2 %和 92 1 %。

| Abstract: | High constant temperatures of 40～48℃ for 2 hours in a laboratory had a strong lethal effect on the eggs,larvae and pupae of Liriomyza huidobernsis Blanchard,with mortality rates exceeding 90% at 45℃.In a greenhouse environment mortality rates of 86^4%,88^2% and 92^1% were recorded for eggs,larvae and pupae respectively when exposed to temperatures of 40～48℃ for 2 hours. |
