Inversion polymorphisms in natural populations of Anopheles stephensi

Abstract
A preliminary survey of natural populations of A. stephensi Liston in Pakistan uncovered the presence of 16 autosomal paracentric inversions. Twelve previously undescribed inversions were observed in the field populations and an additional new one was seen in a laboratory colony. A comparison of urban and rural populations showed striking differences in the kinds and frequencies of paracentric inversions.
