“…Hasan et al 1998 observed reduced fertility in eggs of the Uzi fly, Exorista sorbillans developing from UV-irradiated pupae. The present results support the finding of Beard (1972) who noted that eggs of the Indianmeal moth, Plodia interpunctella , the wax-moth, Galleria mellonella , the large milkweed bug, Oncopeltus fasciatus , and worker termites were remarkably sensitive to UV-irradiation.…”

“…The present findings are also similar to the findings of Beard (1972), who reported that adult emergence was progressively decreased by higher doses when late stage larvae of P. interpunctella were irradiated with UV-rays. Adult emergence was significantly decreased when larvae of T. castaneum (Faruki 2005) and A. diaperinus (Faruki et al 2005) were exposed to UV irradiation.…”

The eggs of the stored grain pests, Tribolium castaneum (Herbst), T. confusum (Duval) (Coleoptera: Tenebrionidae) and Cadra cautella (Walker) (Lepidoptera; Pyralidae) belonging to three age groups, 1, 2, and 3 days-old, were exposed to ultraviolet (UV) radiation with 254nm wavelength (UV-C) for different durations to determine irradiation effects on egg-hatching and adult emergence. An increase in time of exposure to UV-rays caused a gradual decrease in the percentage of hatching of eggs in all age groups of eggs. No hatching occurred after 24 minutes of exposure in 2 and 3 day-old eggs of T. confusum. C. cautella eggs were less sensitive to UV-rays than were T. castaneum and T. confusum eggs. All the exposure periods significantly reduced the eclosion of adults in all the experimental insects. No adults emerged when 3 day-old eggs of T. castaneum were irradiated for 16 or 24 minutes, or from 2 and 3 day-old eggs T. confusum irradiated for 16 or 24 minutes.

“…The lethal effect of UVC (190-290 nm) radiation varies for different insects and different stages of the life cycle. In early development it has been attributed to transmission of UVR into the animal with DNA damage, which could also be the mechanism of mutagenesis (Beard, 1971). In adult animals where growth and development are not occurring, the mechanism is unknown.…”

“…For this reason, we used females that were not blood fed but had sucrose available during the course of the experiments. UV radiation is known to affect some physiological changes in adult mosquitoes (Beard 1972, Sugumaran et al 1992, Jayachandran and Fallon 2004. In a previous study on adult An.…”

Cytochrome b, coded by mitochondrial DNA, is one of the cytochromes involved in electron transport in the respiratory chain of mitochondria. Cytochrome b is a critical intermediate in a mitochondrial death pathway. To reveal whether cytochrome b of the mosquito Aedes aegypti (L.) (Diptera: Culicidae) (AeaCytB) is developmentally regulated, we used real-time quantitative polymerase chain reaction (qPCR) to examine AeaCytB gene expression levels in different developmental stages of Ae. aegypti. The qPCR showed that AeaCytB was expressed in each developmental stage, with peaks at first and second instars and was highly expressed in teneral male and female Ae. aegypti adults. Because mitochondrial genes exist as multiple copies, AeaCytB has much higher expression levels in all developmental stages in Ae. aegypti compared with nuclear genes. We also investigated the effect of abiotic environmental factors (e.g., high temperatures, ultraviolet radiation, and pesticide) on AeaCytB gene expression. Taken together, these results suggest that AeaCytB gene plays an important role in the development of Ae. aegypti and its response to environmental stress.
