Interspecific exploitative competition between Harmonia axyridis and other coccinellids is stronger than intraspecific competition [PDF]

open access: yes, 2019
The invasion of Harmonia axyridis has had negative consequences on coccinellid assemblages, with a decline in abundance and diversity, but the coexistence of invasive and resident species may depend on the strength of intra- and interspecific ...

Prey-Mediated Effects of Drought on the Consumption Rates of Coccinellid Predators of Elatobium abietinum

open access: yesInsects, 2016
Climate change in the UK is predicted to cause an increase in summer drought events. Elatobium abietinum is an important pest of Sitka spruce (Picea sitchensis), causing defoliation of trees, and is predicted to become more abundant in response to ...

Comparative feeding behaviour of coccinellid beetles

open access: yes, 2007
It is evident from that IV instar grub of C. septempunctata and M. sexmaculatus consumed more individuals of aphid than the unstarved adults. The 24 h starved adults of C. septempunctata and M. sexmaculatus consumed more aphids as compared to unstarved adults.

Oviposition responses of aphidophagous coccinellids to tracks of ladybird (Coleoptera: Coccinellidae) and lacewing (Neuroptera: Chrysopidae) larvae

open access: yesEuropean Journal of Entomology, 2001
The effects of oviposition-deterring larval tracks of four aphidophagous coccinellids and two chrysopids were investigated on females of four coccinellid species in choice tests.

The behaviour of individual coccinellid larvae on plants

open access: yesThe British Journal of Animal Behaviour, 1957
Summary The behaviour of coccinellid larvae on plants was studied. They moved on bean leaves, as they did on a flat piece of paper, with frequent changes in direction, but the edges and prominent veins of leaves often determined the pattern of their tracks.

Does Mutual Interference Affect the Feeding Rate of Aphidophagous Coccinellids? A Modeling Perspective. [PDF]

open access: yes, 2016
Mutual interference involves direct interactions between individuals of the same species that may alter their foraging success. Larvae of aphidophagous coccinellids typically stay within a patch during their lifetime, displaying remarkable aggregation to
