Effect of Sex, Age, Starvation and Feeding, Isolation and Crowding and Oviposition on Longevity of Zonocerus Variegatus (Orthoptera: Pyrgomorphidae)
AbstractThe effects of starvation, feeding, sex and oviposition on the longevity of adult Zonocerus variegates L. in isolation or in groups was investigated in the laboratory. Females lived significantly longer than males either in isolation or in groups during feeding and to some extent in starvation. Females in groups with a male-biased sex ratio lived significantly longer than females in groups with a female – biased sex ratio. Oviposition significantly reduced longevity of mated females. Decrease in weight during starvation was gradual and similar in the two sexes.
Key Words: Longevity, Zonocerus feeding, starvation.
