Virginia Tech researchers examine mosquito management via genetic breeding – Tekno Tempo

TEMPO.CO, Jakarta – Virginia Tech researcher, as reported sciencedaily.comdiscover a new technique to determine genetic targets that could be helpful for inhabitants management mosquito. This may very well be one other technique to determine mosquitoes aside from utilizing pesticides.

Their examine, revealed in Communication Biology, targeted on the genetic foundation of species incompatibility. They crossed Ae. aegypti, a serious world arbovirus illness vector and its sister species, Ae. mascarensis, from the Indian Ocean. When the offspring are backcrossed with one of many mother and father, about 10 p.c of the kids change into intersex and can’t reproduce.

The researchers recognized abnormalities within the sex-determination pathways of those interspecific mosquitoes. They discovered that these mosquitoes have been genetically male however expressed each female and male genes, leading to combined bodily traits.

By understanding these genetic elements, they hope to develop methods to create male-only mosquito populations, which may assist management mosquito populations by eliminating feminine mosquitoes. . This analysis may additionally assist determine genes that affect the conduct of feminine mosquitoes, supporting future weed management strategies.

This discovery is taken into account vital for controlling such ailments Zika and dengue fever, as a result of higher mosquito management can scale back the unfold of this illness. “This examine may assist to determine new species identification pathway genes that may very well be utilized in mosquito management methods,” stated Igor Sharakhov, one of many researchers on the undertaking and professor of psychology and affiliated college member of the Fralin Life Sciences Institute.

This analysis may assist with mosquito management by figuring out new pathway genes that decide intercourse to create all-male populations, thereby eliminating females and decreasing grass populations. As well as, the identification of species-specific genes may assist develop genetic constructs to control traits in wild populations.

“As a result of interspecies are genetically male however feminine transcripts are distinct, it gives a system for figuring out genes that affect feminine conduct, which can be helpful for weed management methods sooner or later,” stated Jiangtao Liang, Igor’s colleague pursuing postdoctoral research in psychology.
