ScienceDaily — The requirement for efficient mosquito mass-rearing technology has been one of the major obstacles preventing the large scale application of the Sterile Insect Technique (SIT) against mosquitoes.
The authors of the new article report that the new mechanized rearing unit is simple to handle, maintains minimal water temperature variation and negligible water evaporation, and allows normal larval development. The mosquito mass-rearing tray was designed to provide a large surface area of shallow water that would closely mimic natural breeding sites, and the trays stack into a dedicated rack structure which fill and drain easily. Furthermore, the low amount of labor required to operate the system also reduces costs.
"Our larval rearing unit could enhance any mosquito control strategy in which large-scale releases of mosquitoes are needed to suppress or replace natural populations," said lead author Fabrizio Balestrino.
