Physiological age of female blood-sucking midges (Diptera, Ceratopogonidae) in the south of Tyumen oblast
Despite the fact the fact that biting midges (Diptera, Ceratopogonidae) are abundant blood-sucking insects in a number of areas of Siberia and the Far East, their biology in Russia and abroad is poorly studied. The objective of our research was physiological age of female midges in the subzone of so...

Despite the fact the fact that biting midges (Diptera, Ceratopogonidae) are abundant blood-sucking insects in a number of areas of Siberia and the Far East, their biology in Russia and abroad is poorly studied.
