Abstract

The skin reaction to and comparative activity of mosquito extracts from males, females and pupal cases of Culex pipiens molestus was studied by passive transfer of the immediate sensitivity (P-K test) as well as by direct injection into the skin of subjects sensitive to the bite of the mosquito. The results of P-K tests were not always reproducible and only one out of 4 donor sera gave positive reaction in all 5 recipients tested. Of the three extracts tested, that from female mosquitoes gave the strongest skin response upon injection, but pupal case extract also showed some allergenic activity. Attempts to inhibit the skin reaction to the extracts by their preincubation for 30 min at 37 °C with reaginic donor serum, proved unsuccessful.
