Evolutionary significance of promiscuity in an aphidophagous ladybird, Propylea dissecta (Coleoptera: Coccinellidae) [PDF]
Bulletin of Entomological Research, 2005 AbstractThe short- and long-term consequences of monogamy and promiscuity in an aphidophagous ladybird, Propylea dissecta (Mulsant) in terms of reproductive performance and offspring fitness were investigated. Promiscuous females were more fecund and laid more viable eggs than monogamous ones.

Mating alters the food choices of adult ladybird beetle (Propylea dissecta mulsant)
International Journal of Tropical Insect Science, 2023 Abstract Mating alters nutritional and energetic needs which results 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.

EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES, 2021 Menochilus sexmaculatus and Propylea dissecta (Coleoptera: Coccinellidae) are predaceous ladybird beetles with immense biological control potential. The morphology of the antennae of the adults along with the diversity and distribution of sensilla were investigated using a scanning electron microscope as they are the main sensory organs involved in ...

Journal of Biological Control, 2020 The ability to recognize kin is a well-established behavior across several animal phyla including insects. A laboratory experiment was designed to find out whether adults of an aphid-biocontrol agent, Propylea dissecta (Coleoptera: Coccinellidae) may avoid consuming their own eggs in prey scarcity in the presence of unrelated conspecific eggs.

European Journal of Entomology, 2018 Coccinellids are effective predators and a key component of the predator guild in rice ecosystems. In order to enhance their efficacy, a study was undertaken to assess the seasonal movement of coccinellids into rice fields and the role of the surrounding

Entomologia Experimentalis et Applicata, Volume 173, Issue 5, Page 393-402, May 2025.To attract mates, several coleopteran taxa release volatile sex pheromones via a behaviour termed calling. We studied a postulated calling behaviour in the seven‐spot ladybird Coccinella septempunctata L. for the first time. We also investigated the effects of immediate mating history and the presence of conspecifics on calling behaviour.

EUROPEAN JOURNAL OF ENVIRONMENTAL SCIENCES, 2017 We investigated prey preference of adult male and female Propylea dissecta (Mulsant) when fed on the aphids, Aphis craccivora and Lipaphis erysimi, which sequester toxic allelochemicals from their host plants. Both the male and female adults of P. dissecta prefer to consume L. erysimi in most mixed diet treatments (cafeteria experiment).

, 2023 Abstract We investigated mating reluctance with relatives and its influence on the quantitative progeny and its fitness using a predatory ladybird, Propylea dissecta. For this purpose, we compared mating behaviour, mating duration and post-mating response in the form of fecundity, egg-viability, progeny-development, weight and fitness when ...
