“…It is a polyphagous biocontrol agent (Pervez et al, 2020), which feeds on a wide range of aphids and can also survive on non-aphid diets (Maurice et al, 2011;Shukla & Jadhav, 2014). Coccinella transversalis adults attain sexual maturity soon after their emergence and early sexual activities increase their numbers in the fields (Pervez et al, 2021). However, complex mating behavior and response of C. transversalis need to be studied in the light of mate-choice and multiple mating to manipulate the optimization in their mass-production and augmentation in the laboratory.…”

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

“…However, the newly emerged females were split into three different groups, viz., (i) excess aphid diet (Foodsatiated females), (ii) one-tenth of aphid diet (Fooddeprived females) and (iii) non-aphid sufficient quantity of honey-diet for the next five days (Honeyfed females). It is known that adult males and females become sexually mature in less than five days after emergence (Pervez et al, 2022). Fiveday-old females were paired with respective 5-dayold males fed ad libitum aphids in ten replicates (n=10) in dietary statuses.…”

“…Larger body size also supports sexual coercion (Wallen et al, 2016). The female ladybirds mate more though the behavioural resistance towards remating is also prevalent (Obata, 1988;Perry et al, 2009;Pervez et al, 2022). This female reluctance to remating could be associated with heavy costs, like reduced foraging opportunities (Perry and Rowe, 2015), risk of physical damage (Ronn et al, 2007), elevated mortality (Ronn et al, 2007;Perry and Rowe, 2015), and increased risk of sexually transmitted diseases (Fiedler and Nedved, 2019).…”

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