Positive and negative interspecific interactions between coexisting rice planthoppers neutralize the effects of elevated temperatures

Global warming is often predicted to increase damage to plants through direct effects on insect herbivores. However, the indirect impacts of rising temperatures on herbivores, mediated through interactions with their biotic environment, could dampen these effects. Using a series of reciprocal density experiments with gravid females and developing nymphs, we examined interspecific competition between two coexisting phloem feeders, Nilaparvata lugens (BPH) and Sogatella furcifera (WBPH), on rice at 25°C and 30°C. WBPH performed better (i.e.,...
