Acting against or opposing mosquitoes of the genus Anopheles, which transmit malaria.
From Greek 'anti-' (against) + 'Anopheles' (a genus of mosquitoes whose name comes from Greek 'anopheles' meaning harmful or useless). The term emerged in early 20th-century medical literature as malaria transmission was being understood.
When scientists realized mosquitoes spread malaria, they needed a word for anything that fights back against these specific deadly insects—this term represents humanity's fight against one of history's deadliest diseases.
