Effects of some ecological factors on the developmental biology of Dysdercus koenigii Fabr. (Pyrrhocoridae:Heteroptera). III. Effect of crowding


Effects of some ecological factors on the developmental biology of Dysdercus koenigii Fabr. (Pyrrhocoridae:Heteroptera). III. Effect of crowding



Journal of Applied Zoological Researches 10(1): 42-44



ISSN/ISBN: 0970-9304

The effects of population density (1, 2, 4, 8, 16, 24, 32, 64, 96, 128, or 200 pairs) on the developmental biology of D. koenigii, reared on okra seeds, was investigated for 3 successive generations. Fecundity, fertility, lifespan, developmental period, and survival rate decreased as the density increased and it continued across generations.
