摘要
在17，21，25，29和33℃下测定了黄腹潜蝇茧蜂Opius caricivorae Fischer对美洲斑潜蝇Liriomyza sativae Blanebard的功能反应。结果表明，在17—33℃范围内的各个温度下的功能反应均能用Holling Ⅱ型圆盘方程较好地拟合。各温度下的功能反应参数存在着显著差异，33℃下的瞬时攻击率比17—29℃下的显著地高，而17℃低温和33℃高温下的处置时间比21，25和29℃的显著延长，25℃下的处理时间最短。相同寄主密度下寄生率在25℃达到最高。
The functional response of Opius caricivorae Fischer （Hymenoptera： Braconidae） to the density increase of Liriomyza sativae Blanchard （Diptera： Agromyzidae） larvae was examined at the different temperatures （17, 21, 25,29 and 33℃ ）. The results showed that the functional response could be described very well by the disc equation of Holling type Ⅱ at all tested temperatures. The parameters of functional response differed significantly at the different temperatures, the rates of successful attack at 33℃ was significantly higher than those at 17 - 29℃, the handling time at 17℃ and 33℃ were longer than those at 21, 25, 29℃ with that at 25℃ the shortest. The percentage of host parasitized at 25 ℃ was the highest at the same density of host larvae.
