Male Age Effect on Male Remating and Fitness in Phorticella Striata

Abstract

Male traits known to influence on female mating decision were also known to influence on male remating ability too. In Phorticella striata age of male effect on male remating and progeny production has been studied. It was noticed that middle aged male had greater percentage of remating than those of young and old males. In all the three male age classes male mated with two females in 1 hour had copulated significantly for longer time, mated females laid greater number of eggs and more progeny than male mated with one female in 1 hour. Further, among male mated with two females in 1 hour, male mated with 1 st female copulated longer, mated female laid greater number of eggs and progeny production than male mateed with 2 nd female in 1 hour. Thus, these studies in Phorticella striata suggests that male age has significant influence on male remating and progeny production. Middle aged male had greater remating and progeny production than young and old males.

Male remating and its influences on queen colony foundation success in the bumblebee, Bombus terrestris

“…Studies have shown that male remating increases male fitness in some insect species, such as Drosophila ananassae (Singh and Singh 2000) and Phorticella striata (Latha and Krishna 2014). It has also been reported that a positive correlation exists between remating success and male size in Drosophila bipectinata (Prasad et al 2008).…”
