For food security and sustainable crop protection, it is a necessity to optimize the massrearing augmentation of biocontrol agents numerous aphid pests. Coccinellids, commonly known as ladybird beetles, are potential predators on several sucking pests promising agents. In present investigation, laboratory experiments were performed find out whether manipulation mate choice in aphidophagous Coccinella transversalis Fabricius (Coleoptera: Coccinellidae) under varying mating status could influence reproductive output terms high fecundity. It was found that highly affects duration The commenced earlier presence different males than females an arena. lasted for longer between virgin multi-mated vice-versa. bouts copula increased with increase both sexes. Females more fecund unmated females. Thus, study will be useful quantitative mass-rearing C. aphids thereby enhancing productivity protection.

The nutritional condition and body size influence the mating female remating behaviour of a predaceous ladybird, Coccinella transversalis. When well-fed males were provided with females three different dietary conditions, viz. (i) well-fed, (ii) food-deprived (iii) honey-fed, ones most fecund highest percentage egg-viability least preoviposition period refusals, while showed vice-versa. However, honey-fed laid unfertile eggs after coercively males, resisted to remate, which gets strengthened in second trial. This indicates females’ modulates post-mating outcomes. adult was directly proportional reproductive output heavier showing high fecundity egg viability than lighter ones. Large remate larger smaller large mated females. Regardless body-size, resistance enhanced Both diet modulate re-mating C. transversalis, as greatly re-mate males.
