Abstract

Mating alters nutritional and energetic needs which result in behavioural and physiological changes related to reproduction. But little is known as to how mating influences sex specific food preferences in ladybird beetle, Propylea dissecta (Mulsant). To explore this, 10-day old adults were subjected to different time mating interruption treatments, i.e., no mating, 30, 60, 90, 120, 150, 180 min and complete mating (211 ± 8.1 min) and post mating they were then provided with food choice (i.e., Aphis craccivora, conspecific eggs, and heterospecific eggs) separately in Petri dish. Results show that on increase in mating duration females showed altered food choice whereas it was found to be insignificant in males. However, in both the sexes time to consume first prey was decreased on increase in mating duration possibly to cope with high energy expenditure and to fulfil their instant food requirements. Our results indicate that mating modulates sex-specific food preference in ladybird beetle, P. dissecta.
