The Effects of Immersion in Water on Survival to Eclosion of the Embryos of the Buffalo Fly, Haematobia Irritans Exigua De Meijere (Diptera: Muscidae).

Abstract

Within 15 min of oviposition, eggs of the buffalo fly were immersed in water for various periods at constant temperatures of 20,25,30 or 35°C. Mortality among the embryos increased sharply with the duration of immersion. At all temperatures except 25°C, survival levels were predicted to be low when immersion times approached the normal developmental periods.
