Field studies were done of the responses of Glossina palpalis palpalis in Côte d'Ivoire, and G. p. gambiensis and G. tachinoides in Burkina Faso, to odours from humans, cattle and pigs. Responses were measured either by baiting (1.) biconical traps

We investigated the residual efficacy of four insecticide formulations used in Chagas disease vector control campaigns: cyfluthrin 12.5% suspension concentrace (SC), lambda- cyhalothrin 10% wettable powder (WP), deltamethrin 2.5% SC, and 2.5% WP on f

Trypanosomes in the dissection-positive proboscis of Glossina pallidipes were identified by PCR using species-specific primers. Of the 3741 flies dissected 643 were proboscis positive. PCR was performed on 406 dissection-positive probosces giving pos

Summary The age structure of mosquito populations is of great relevance to understanding the dynamics of disease transmission and in monitoring the success of control operations. Unfortunately, the ovarian dissection methods currently available for d

The three-layered peritrophic matrix of Glossina morsitans morsitans is shown, by histochemistry, to be formed of a mixture of glycosaminoglycans, glycoproteins and chitin. In all three layers the glycosaminoglycans contain GlcNAc-hexuronic and Gal-G

Under conditions of declining nutritional status ca. 50 % of egg laying in a population of Triatoma infestans occurred after they had flown. This was not simply a reflection of the correlation between the time taken to mature a batch of eggs and the

Some aspects of flight behaviour in the triatomine bug Triatoma sordida were investigated. A strong link between flight initiation and nutritional status as expressed by weight: length ratio was shown. Flight activity was strongly nocturnal and unimo

The effect of feeding fifth instar Triatoma infestans nymphs at one, two and three week intervals was investigated. There were clear sex differences. Females fed most frequently emerged as larger, longer-lived adults better able to produce eggs autog
