Epidemiology of benign breast disease in rural population of north Maharashtra

Abstract

The experiment was conducted in laboratory conditions at the Department of Entomology, College of Agriculture, Badnapur, during 2023-24 under laboratory conditions at 25 ± 1.5 °C temperature with relative humidity of 65 ± 5 percent. The study was primarily cantered on observations such as incubation period, percent viability of eggs, larval period, pupal period, adult longevity, percent emergence for adults, sex ratio, total life cycle, and larval and pupal weight from each hybrid. The study on the biology of Spodoptera litura (Fab.) on cabbage revealed that the S. litura development duration was observed as 4.53 ± 0.01 days to 4.80 ± 0.01 for the egg, 17.87 ± 0.29 days to 20.47 ± 0.04 days for the larva, 2.78 ± 0.05 days to 2.94 ± 0.02 days for the pre-pupa, 8.66 ± 0.09 days to 9.55 ± 0.10 days for the pupa, 4.84 ± 0.04 days to 4.91 ± 0.02 days for the adult male, 6.15 ± 0.04 days to 6.37 ± 0.02 days for the female, and the total life cycle varied between 34.16 ± 0.39 days to 37.88 ± 0.12 days.
