✦ Synopsis

Several properties of the salivary glands of

Culex quinquefasciatus mosquitoes were analysed. The amount of protein in female salivary glands increased from 0.26 mg on day one after emergence to about 1.4 mg on day seven. The major polypeptides found in the female salivary glands had molecular weights of 35.7, 28.3, and 20.5 kDa. Antibodies produced by mice immunized by bites of Culex quinquefasciatus female mosquitoes reacted with the 35.7 and 28.3 kDa polypeptides, showing that these molecules were secreted by mosquitoes during blood feeding. The salivary glands of C. quinquefasciatus females displayed the same morphological and biochemical organization as that of Aedes aegypti mosquitoes, accumulating apyrase in the distal portions and a-glucosidase in the proximal portions of the gland.

Cufex vishnui is a member of the vishnui group comprising six closely resembling species. The salivary gland chromosomes are longer than those found in Anopheles, more fragile and spread with difficulty. The banding pattern is compared with that of Culexpipienspipiens and Culexpipiensfatigans. Homol
