Abstract

Abstract: Indoor resting blood-fed anopheline mosquitoes were collected from five localities in Ethiopia. Cytogenetic and bloodmeal determinations were conducted. Anopheles arabiensis was the only sibling species identified in all of the study localities. Paracentric chromosomal inversion polymorphisms were observed on 2R and 3R arms. The highest cattle-fed percentage was from those mosquitoes collected from cattle sheds (47.5%) followed by mixed dwellings(44.2%) and human dwellings (3.9%). Statistically significant correlation (r=0.94, P<0.001) was observed between the frequencies of 3Ra inversion and cattle feeding. [Ethiop. J. Health Dev. 1998;12(1):23-28]
