Karyotypic variation and geographic distribution of Anopheles campestris-like (Diptera: Culicidae) in Thailand
Seventy-one isolines of Anopheles campestris-like were established from wild-caught females collected from human-biting and animal-biting traps at 12 locations in Thailand. All isolines had an average branch summation of seta 2-VI pupal skins ranging from 20.3-30.0 branches, which is in the range of...
