Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass

Entomologia Experimentalis et Applicata, EarlyView.
Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Predicting the potential geographical distribution of the harlequin ladybird, Harmonia axyridis, using the CLIMEX model - BioControl [PDF]

, 2008
Harmonia axyridis (Pallas, 1773) (Coleoptera: Coccinellidae) is a ladybird beetle native to temperate and subtropical parts of Asia. Since 1916 populations of this species have been introduced throughout the world, either deliberately, or by accident ...

A Smelly Conflict: The Role of Olfactory Information in the Interaction of Insect Herbivores and Their Natural Enemies

Entomologia Experimentalis et Applicata, EarlyView.
Insect herbivores rely on olfactory cues to locate natural‐enemy‐free spaces for feeding or ovipositing; conversely, natural enemies detect herbivores by chemical cues from damaged plants or from the herbivores themselves. Based on the reviewed findings, we suggest that herbivores and natural enemies converge towards using specific olfactory cues. This

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

Plant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Geographical proliferation of ongoing novel host use by the herbivorous ladybird beetle Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae)

Entomological Science, Volume 29, Issue 4, December 2026.
The geographical extent of occurrence of the Solanaceae‐feeding Henosepilachna vigintioctopunctata on the novel fabaceous host Centrosema molle and the ability of larvae from several beetle populations to develop on C. molle were investigated to depict the incipient phase in the speciation continuum of herbivorous ladybird beetles.

Natural enemies of the currant lettuce aphid, Nasonovia ribisnigri (Mosely) (Hemiptera: Aphididae) and their population fluctuations in Ahvaz, Iran

Journal of Crop Protection, 2014
Nasonovia ribisnigri (Mosely) is one of the most important pests of the lettuce plant and it was reported for the first time in Ahvaz in 2008. In order to investigate the dominant species of its natural enemies and their population fluctuations, sample ...

Triangular fecundity function and ageing in ladybird beetles [PDF]

Ecological Entomology, 2002
Abstract 1. In insects, the age schedules of fecundity tend to be triangular and this has been attributed more to temporal patterns of mortality than to fecundity. The objective of the work reported here was to test the assumption that senescence shapes the fecundity function in ladybird beetles, and in ...
