Temporal variation in elytral colour polymorphism in Hippodamia variegata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2012
Lady beetles (Coleoptera: Coccinellidae) are a classical group for studying the mechanisms that determine local and temporal trends in colour polymorphism. Here we report long term trends in variation in the percentage of different morphs in a population

Parental age at mating affects reproductive attributes of the aphidophagous ladybird beetle, Coelophora saucia (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2010
Ageing and its affect on life attributes have not been widely explored in ladybirds. The present study investigates the influence of female and male age at mating on the reproductive attributes of the ladybird beetle, Coelophora saucia (Mulsant).

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

open access: yesJournal of Applied Entomology, Volume 150, Issue 4, Page 444-453, May 2026.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

Life table parameters of the aphid predators Coccinella septempunctata, Ceratomegilla undecimnotata and Propylea quatuordecimpunctata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2008
The life tables of the aphid predators Coccinella septempunctata L., Ceratomegilla undecimnotata (Schneider) and Propylea quatuordecimpunctata (L.) (Coleoptera: Coccinellidae), fed on Aphis fabae Scopoli (Hemiptera: Aphididae), were constructed at ...

Abundance of Coccinellids and Their Potential Prey in Field-Crop and Grass Habitats in Eastern South Dakota [PDF]

open access: yes, 2018
A rich fauna of coccinellids occurs in eastern South Dakota, but the abundance of some species has declined in association with the establishment of an exotic lady beetle, Coccinella septempunctata (L.) (Coleoptera: Coccinellidae), in the mid-1980s.

Beneficial rhizobacteria and virus infection modulate the soybean metabolome and influence the feeding preferences of the virus vector Epilachna varivestis

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2599-2618, May 2026.
Summary Beneficial rhizobacteria and viral pathogens can both alter host plant phenotypes, yet little is known about how their simultaneous presence influences plant metabolism and species interactions. We investigated how two rhizobacteria, Bradyrhizobium japonicum and Delftia acidovorans, together with bean pod mottle virus (BPMV), shape soybean ...

Temperature-dependent development of the two-spotted ladybeetle, Adalia bipunctata, on the green peach aphid, Myzus persicae, and a factitious food under constant temperatures [PDF]

open access: yes, 2010
The ability of a natural enemy to tolerate a wide temperature range is a critical factor in the evaluation of its suitability as a biological control agent.

Effects of larval diet on female reproductive output of the European coccinellid Adalia bipunctata and the invasive species Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2008
Cannibalism and intraguild predation (IGP) are both common phenomena amongst aphidophagous coccinellids and serve as vital alternative feeding strategies which can prolong survival during periods of aphid scarcity.
