Interaction of High Temperature Stress and Wolbachia Infection on the Biological Characteristic of Drosophila melanogaster

It was reported that temperature affects the distribution of in the host, but only a few papers reported the effect of the interaction between high temperature and on the biological characteristic of the host. Here, we set four treatment groups: -infected flies in 25 °C (W M), -infected flies in 31 °C (W H), -uninfected flies in 25 °C (W M), -uninfected flies in 31 °C (W H), and detected the interaction effect of temperature and infection on the biological characteristic of in F , F and F generations. We found that both temperature and infection had significant effects on the development and survival rate of . High temperature and infection had interaction effect on hatching rate, developmental durations, emergence rate, body weight and body length of F , F and F flies, and the interaction effect also existed on oviposition amount of F flies, and on pupation rate of F and F flies. High temperature stress reduced the vertical transmission efficiency between generations. These results indicated that high temperature stress and infection had negative effects on the morphological development of .
