UV-C Radiation Effect on the Mortality of Fruit Fly Eggs

Abstract

The current work evaluate death kinetics of Ceratitis capitata eggs immersed in water and subjected to different doses of UV-C radiation: 0 (Control); 0.087; 0.261; 0.348; 0.461; 0.692; 0.922; 1.384; 4.152; 5.534 and 8.302 kJ m-2. After treatments, eggs placed in Petri dishes were incubated at 25ºC under light/darkness or in complete darkness. One day after treatments, egg survival was microscopically evaluated. Doses of 1.384 kJm-2 UV-C or higher led to 100% death of C. capitata eggs incubated in a light/darkness cycle.
