Heat shock response during development of the malaria vector Anopheles stephensi (Culicidae: Diptera).
The pattern of synthesis of heat shock proteins (HSP) and thermotolerance to elevated temperatures during the development of the malaria vector Anopheles stephensi normally reared at 28 +/- 2 degrees C was studied using SDS-PAGE. In total twelve heat shock proteins (i.e. 31, 33, 38, 43, 44, 51, 57, 62, 69, 71, 113 and 121 kD were induced by heat shock during various stages of development. Eight polypeptides (HSP during one or other of the instars) appeared during normal development of the adult, which showed very little response towards heat shock. Only two polypeptides (57 and 69 kD) were induced while the 22.5 kD protein disappeared during adult life. The HSP 62 and 71 kD induced during the larval stages showed a sharp decline in quantity in male and female adults upon heat shock. Three HSP (31, 43 and 44 kD) were induced in pupae due to heat shock. The synthesis of HSP in A. stephensi was correlated with the various morphological and physiological events occurring during development.
