Desiccation tolerance in Anopheles coluzzii: the effects of spiracle size and cuticular hydrocarbons.

Arcaz AC, Huestis DL, Dao A, Yaro AS, Diallo M, Andersen J, Blomquist GJ, Lehmann T - J. Exp. Biol. (2016)

Bottom Line: A smaller spiracle size appeared to increase A. coluzzii's desiccation tolerance, but was not statistically significant.Seasonal changes in CHC composition were detected in Sahelian A. coluzzii Stepwise regression models suggested the effect of particular CHCs on desiccation tolerance.In conclusion, the combination of particular CHCs along with the total amount of CHCs is a primary mechanism conferring desiccation tolerance in A. coluzzii, while variation in spiracle size might be a secondary mechanism.

Effects of mesothoracic and metathoracic spiracle size (length) on DT. Top, overall results; bottom, results by season. Red and blue denote DS and RS, respectively. Correlation coefficients and their significance are shown for the top panels.

JEB135665F9: Effects of mesothoracic and metathoracic spiracle size (length) on DT. Top, overall results; bottom, results by season. Red and blue denote DS and RS, respectively. Correlation coefficients and their significance are shown for the top panels.

Mentions: The effect of spiracle size on DT was evaluated in univariate and multivariate ANCOVA. Although a larger spiracle appeared to decrease DT, according to the hypothesis (Fig. 9), these effects were non-significant (including in multivariate analyses, not shown).Fig. 9.
