Trade-offs between survival, longevity, and reproduction, and variation of survival tolerance in Mediterranean Bemisia tabaci after temperature stress.

Lü ZC, Wang YM, Zhu SG, Yu H, Guo JY, Wan FH - J. Insect Sci. (2014)

Bottom Line: The results showed that survival and longevity of Mediterranean B. tabaci were decreased significantly after direct or cross temperature stress and that the number of eggs per female was not reduced significantly.Furthermore, heat-shock selection dramatically increased the survival of Mediterranean B. tabaci within two generations, and it did not significantly affect the egg number per female within five generations.These results indicated that there was a trade-off between survival, longevity, and reproduction in Mediterranean B. tabaci after temperature stress.

Compared with the treated control (L or H), the effects on survival rate, longevity, and egg number (per female) of Mediterranean B. tabaci adults after cross stress treatment (HL or LH). L: -12°C for 1 h; HL: 39°C for 1 h → recovery at 26°C for 1 h → -12°C for 1 h; H: 45°C for 1 h; LH: 10°C for 1 h → recovery at 26°C for 1 h → 45°C for 1 h. Values are the means + SEM. Asterisks denote significant differences at P < 0.05.

L: -12°C for 1 h; HL: 39°C for 1 h → recovery at 26°C for 1 h → -12°C for 1 h; H: 45°C for 1 h; LH: 10°C for 1 h → recovery at 26°C for 1 h → 45°C for 1 h. Values are the means + SEM. Asterisks denote significant differences at P < 0.05.

Mentions: Compared with the adults exposed to -12°C for 1 h, Mediterranean B. tabaci adults had a significantly reduced survival rate and longevity after exposure to 39°C for 1 h followed by recovery at 26°C for 1 h and exposure to -12°C for 1 h (survival rate: t = 5.65, P < 0.001; longevity: t = -2.97, P < 0.01), and the number of eggs per female was significantly increased (t = 3.16; P < 0.01) (Fig. 2A). Compared with the whiteflies exposed to 45°C for 1 h, whiteflies had a significantly reduced survival rate and longevity after exposure to 10°C for 1 h, followed by recovery at 26°C for 1 h and exposure to 45°C for 1 h (survival rate: t = 7.63, P < 0.001; longevity: t = 2.40, P < 0.05), and the number of eggs per female was not changed significantly (Fig. 2B).
