Stress Response of Different Exposure Time by UV 254 on the Biology and Body Total Protein and Genomic DNA Content of Red Cotton Bug
Kitherian Sahayaraj and Nithyanatham Auxelia

Abstract: UV 254 nm radiation generally considered as a germicide and its impact has not been studied against highly mobile agricultural pest, Dysdercus cingulatus Fab. Newly hatched egg of D. cingulatus Fab. was exposed with UV 254 nm radiation and the consequence such as nymphal development and survival, morphogenetic effect and whole body protein and genomic DNA content were evaluated under laboratory conditions. Exposure of UV 254 nm radiation prolonged the nymphal developmental period from 1-7 days, reduced the nymphal survival rate and caused both in nymphs and adults morphological deformities. However, the total body protein contents increased up to third instar of D. cingulatus and then it decreased. Whereas, the whole body genomic content increased from 5-20 min UV-C exposure. Hence, UV 254 nm radiation has been considered for its impact on terrestrial animals including insect pests.
