日短期高温对南美斑潜蝇实验种群的影响

Effect of short term high temperature during a day on the laboratory population development of Liriomyza huidobrensis (Blanchard)

研究探讨了 4种日短期高温 ( 31、34、37、4 0℃ )对南美斑潜蝇种群发展的影响 .结果表明 ,随着日短期温度的升高 ,南美斑潜蝇的产卵期、产卵量和存活率明显下降 ,而发育历期反而延长 .31℃时 ,南美斑潜蝇的内禀增长力 ( rm)和周限增长率 (λ)分别为 - 0 .0 0 90和 0 .9910 ;34℃时 ,rm 和λ则分别为 - 0 .0 685和 0 .9338,均呈下降趋势 ;当温度上升至 37与 4 0℃时 。

The present paper report a new genus of Fovephedrus and 6 Chinese species, among which four species, F. radiatus, F. longus, F. transversus and F. rugosus are new to China. Fovephedrus palaestinensis(Mackauer) is recorded for the first time from China. All type specimens are deposited in Biological Control Research Institute, FAC.
