Effects of UV-Radiation on the Larvae of the Lesser Mealworm, Alphitobius diaperinus (Panzer)(Coleoptera: Tenebrionidae) and Their Progeny

The effect of UV-radiation on the larvae of the lesser mealworm, Alphitobius diaperinus (Panzer) was investigated for different exposure periods. Larval mortality, formation of pupae, adult emergence and deformities; growth of larvae, pupae and adults and reproductive potential of the developing progeny were recorded. The early instar larvae were more susceptible to UV-rays by increasing their mortality. UV-rays significantly inhibited development to pupae and adults, growth of larvae, pupae and adults. It was observed that irradiation produced deformities in different developmental stages. Fecundity and egg-fertility were also notably reduced following by irradiation.
