Extract

Precipitin tests were performed on 238 blood-smears made from Culicine mosquitos collected from natural resting places at three sites, in the area surrounding a village, in uninhabited forest, and at an uninhabited rock outcrop in savannah vegetation in Northern Nigeria. In calculating the percentages of blood-meals that were positive for the various animals, the following criteria were applied: all negative results were subtracted from the totals tested; in calculating mammalian, but not avian or reptilian, percentages, all records that referred to “mammal, weak smear” were subtracted; “unidentified mammal” was included in the calculations. Results showed that Culex pipiens fatigans Wied. (taken only in the area surrounding the village) had fed mainly on man (45%) and birds (36%), and while Aedes vittatus (Big.) (taken only at the rock outcrop) fed to some extent on both man (14%) and birds (18%), the majority of blood-meals (54%) had been obtained from the porcupine (Histrix cristata). It is thought that these feeds on man from individuals of Ae. vittatus taken at an uninhabited site may have been obtained from villagers using a road about 150 yd. from the outcrop. Ae. luteocephalus (Newst.) (the majority of which were taken in forest) also fed to some extent on porcupine (11%) and birds (16%), but the principal host appeared to be Bovids (74%). It was established for the first time that Uranotaenia mashonaensis Theo. (the majority of which were taken in forest) bites man (29%); mammals other than man and birds accounted for 29 and 24 per cent., respectively. Half of the blood-smear samples obtained from females of this species did not react to any antisera, and were classified as negative.
