This study examined effects of elevated CO2 alone and in combination with temperature on plant-aphid interactions. levels which the host plants were grown affected durations some nymphal stadia, but not survivorship within each instar or all instarS. Sipha flava (Forbes) (Hemiptera: Aphididae) adults kept under a constant high environment (500 ppm) fed fluctuating (avg. 440 greenhouse had significantly greater longevity reproduction than aphids either level 368 ppm). Nevertheless, no significant differences observed these biological parameters S. that individually greenhouse, regardless temperatures used to feed them grown. However, populations produced more nymphs did those climate-controlled chamber The decreased duration reproductive success survival. Adults fewer an lower temperatures. Based results, we concluded will decrease future climatic conditions when both concentration atmospheric are projected increase.
