Effects of Gamma Irradiation on the Survival and Development of the Multicolored Asian Ladybird Beetle, Harmonia axyridis (Coccinellidae, Coleoptera)
Abstract
, , The effects of gamma irradiation on the survival, development, fecundity, and sex ratio of the multicolored Asian ladybird beetle (Harmonia axyridis) were investigated. A dose of more than 50 Gy dose of irradiation on eggs completely inhibited hatch, and 1st and 3rd instar larva irradiated with over 40 Gy almost died. Adverse effects of gamma irradiation over 70 Gy were also observed in the survival and development of pupae and adults. tail indicating DNA damage was showed in survival individuals exposed to gamma irradiation.Although irradiated individuals usually survived, they had longer periods of larval and pupal development than untreated individuals. Slight female-biased sex ratios were observed in some treatments. However, sex ratio differences soon equilibrated. Generally, inherited harmful effects of gamma irradiation were observed in F1 and F2 generations. Comet tail indicating DNA damage was showed in survival individuals exposed to gamma irradiation.
