The present article considers some aspects of a peridomestic population of the tsetse fly Glossina palpalis palpalis Robineau-Desvoidy, 1830 in Kontagora, Nigeria. This situation characterizes an abnormal behaviour of the vector, and it is of significant epidemiological importance. Data on the ecology of this species were collected in 1995 and 1999. The results indicated that the species exists during both dry and wet seasons; approximately 30.0% of the catches were gorged with blood giving a MHS of 2.4, indicating a well-nourished population. Dissection of inseminated pars indicated pregnancy rates of approximately 30.0% and 70.0% in the dry and wet seasons and the presence of all 4 stages of pregnancy, suggesting that breeding occurs at both seasons. Longevity of flies was approximately 16 days in dry season and 25 days in the wet season. Overall results indicated that vector/host contact was high and the fly population has adapted and actively breeding in the area. Trypanosome infection rates of 18.2% consist of 1 brucei-type and 5 vivax-type infections. The public health implications of the close proximity of the wild natural reservoir hosts of the human T. b. gambiense Dutton, 1902 parasites at the Kainji Wild Life park is discussed.

AbstractInsecticide-impregnated blue cotton targets 70 × 110 cm weretested for the control of Glossina palpalis palpalis (Robineau-Desvoidy) and G. tachinoides Westwood in riverine fringing forests in central Nigeria, under wet-season conditions. Following exposure to treated cloth for 1·5 min, delta-methrin caused 100% mortality of G. p. palpalis for six weeks at 0·05% and for 13 weeks at 0·1%. Dieldrin at 5% was not very effective. At 4%, endosulfan initially caused a high mortality, but rapidly lost its activity, especially against females. By chemical analysis, 43% of deltamethrin applied to the fabric was found to have been lost within 12 weeks, in which 230 mm of rainfall was recorded. Placed 150 m apart in a fringing forest, targets impregnated with 0·05% deltamethrin caused a rapid decline in the G. p. palpalis population, and after 12 weeks only 5% of the original density was recorded. No further reduction or significant increase was observed during the following six months, though it appeared that flies caught during this period had immigrated from an adjacent undisturbed riverine forest. The effect on G. tachinoides was less dramatic, but this may have been due to the low initial density of this species, and to its greater mobility, giving rise to reinvasion from elsewhere.
