Animal burrows are major habitats for both P. martini and P. duboscqi, vectors of visceral and cutaneous leishmaniases in Kenya. In burrows, both species were collected throughout the year. The highest relative abundance of P. martini and P. duboscqi was recorded in August and in April, respectively. The lowest relative abundance was observed in july for P. martini and in October for P. duboscqi. In termite mounds, P. martini was present all the year round, but P. duboscqi was absent for the greater part of the year. The highest relative abundance of P. martini was observed in November and April, while that of P. duboscqi was seen in March and April. The lowest relative abundance of P. martini was recorded in July. In termite mounds, P. duboscqi showed a significant positive correlation with rainfall, contrary to P. martini which did not afford any significant correlation with any environmental factor. Rainfall, relative humidity and ambient temperature did not correlate with relative sandfly abundance in animal burrows.
