|Publication abstract=Temperature is a primary factor that determines geographic insect boundaries and population developments. Insect responses to temperature stress are particularly important in invasive species. ''Bemisia tabaci'' is a genetic complex of closely related whiteflies. Invasive and indigenous species were used to test genotype responses to temperature stress. To determine whether thermal tolerance is related to differential expression of heat shock proteins (''hsp'') under temperature stress in two invasive and native sibling species, commonly referred to as the biotype B and biotype Q of ''B''. ''tabaci'', we analyzed the expression profiles of ''hsp90'' and ''hsp70'' and ''hsp20'' across temperature gradients using real-time quantitative polymerase chain reaction. The ''B''. ''tabaci'' invasive species Q is more tolerant to short temperature stress than the indigenous species ZHJ1, and the onset (T<sub>on</sub>) or maximal (T<sub>max</sub>) temperature induction of ''hsp'' expression in the ''B''. ''tabaci'' invasive species Q was generally 2-4°C higher than that found in the indigenous species ZHJ1. Our results demonstrate differences in gene expression between these closely related and sympatric ''B''. ''tabaci'' sibling species, suggesting that these differences account for the better adaptation of invasive species over indigenous species. These differences may eventually lead to changes in the local and global distribution of both species in a warmer world.
