Haemagogus spegazzinii Brèthes, 1912 (Diptera: Culicidae) in Brazilian semiarid: resistance in eggs and scale color variation in adults

Although aedine eggs are resistant to desiccation, little is known about this trait in Haemagogus species. In study, we assessed the desiccation resistance of Hg. spegazzinii eggs. The were collected using ovitraps over a period one week March 2020. positive pallets stored until experimentation and immersed solution water yeast for larval hatching subsequent species identification. emerged adults morphologically identified as spegazzinii. Because color variations, classified into three groups. was measured 380 days. Desiccation likely result selection mechanisms responsible maintaining populations seasonally dry tropical forest (Caatinga) Brazilian semiarid region.
