Patterns of Wild Pupae Emergence from 2000-2009 at the Insectary of Departmentvector and Parasitological Studies Nigerian Institute for Trypanosomiasis Research (NITR) Kaduna Nigeria

To determine the pattern of fly emergence from pupae collected from Suleja out station from 2000- 2009 and to provide data base for pupae collection from 2000-2009, Data of pupae collected from Suleja out station at the fly room of Nigerian Institute for Trypanosomiasis Research was consulted from 2000-2009, in which number of fly emergence from pupae brought from the station were recorded based on date of emergence and sex of the fly that emerged. Data on wet bulb, dry bulb, temperature and relative humidity of the fly room were not updated as only data of 2006-2007 were recorded which cannot be use to generalize statement. Results from 2000-2009 a total of 4,331 flies emerged from pupae brought from Suleja out station. Fly emergence rose from 292 flies in 2000 to 784 flies in 2003 and declined drastically to 184 flies in 2006 and rose up to 380 flies in 2008 and declined to 185 flies in 2009, The number of emergence decreased between April and September which corresponded with dry season; by October, the number of emergence started to increase. Conclusions from the findings suggested that Pupae from the field could be obtained between late November and February. At that period, the rate of fly emergence will also be high; this means that for any scientist that requires pupae or tsetse flies for research, these are the best period where flies and pupae can be available.
