Mosquitoes and Malaria

Abstract

IT may be of interest to record the fact that though during the months of June, July and August I collected and examined about 300 mosquitoes in this town, I only came across one specimen of the spotted-winged mosquito which is described as the malaria-conveying species by Major Ross. The majority, quite 75 per cent. of the specimens captured, were the harmless grey kind, the rest being chiefly the equally harmless tiger or brindled species. The single spotted-winged specimen I found in my house on a mosquito curtain. The rarity of its occurrence will, according to Major Ross's theory, account for the comparative absence of malaria in Singapore.
