Description
Romoli and co-authors show that B vitamins from gut bacteria shape mosquito development in sex specific ways. Young mosquitoes need these vitamins, and larvae cleared of bacteria stall without them. Their 2024 study fed larvae set vitamin mixes and tracked which adults emerged.
A mix of seven B vitamins did not boost development success, but it skewed the adult sex ratio toward females. Testing vitamins one by one found that biotin, vitamin B7, turned toxic at high doses. Males succumbed at lower doses than females. Larvae given few or slow growing bacteria yielded more males instead. The authors conclude males need fewer bacteria derived nutrients than females during growth. Vitamin supply from bacteria thus shapes the next generation in uneven ways.
