Abstract:
Tribolium castaneum (Tenebrionidae: Coleoptera) eggs, 24, 48, 72 and 96 h old, were exposed to UV radiation from a 15-w lamp emitting energy at the 254 run wavelength with an intensity of 600 μW/cm2 . Mortality was assessed by determining the hatching of eggs and larval survival, 14 days after exposure. Older eggs were found to be more susceptible to UV radiation than younger ones. The results also showed an obvious trend toward higher mortality when recorded after 14 days, as compared with mortality determined by egg hatch, at the same UV dosage and exposure times. For example: LT95 of 48-h-old eggs was 186.91 sec when determined by hatching and 127.97 sec when recorded after 14 days by larval survival. © 1985, Springer Science + Business Media B.V..
