Impact of food scarcity on the foraging dynamics of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae) Impacto da escassez de alimentos na dinâmica de forrageamento de Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

open access: yesAgricultural and Forest Entomology, EarlyView.
Starvation duration alters predatory behaviour of Eriopis connexa, affecting aphid consumption and survival dynamics. Increased starvation enhances attack rate, accelerating prey depletion without substantially affecting handling time. Functional response remains type II, with stronger predation under prolonged food deprivation.

Coccinellids (coleoptera:coccinellidae) in citrus groves in Portugal: listing and analysis of geographical distribution

open access: yes, 1999
Coccinellids were sampled in 88 citrus groves from the centre / south of continental Portugal. Analysis of distribution were performed by the usual indices but also with the help of a new method - SADIE.

Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Species composition and host range of predatory Coccinellids (Coleoptera) in Doon valley, Uttarakhand, India

open access: yesEnvironment Conservation Journal
Coccinellid beetles play an important role in pest control, as these Coleopteran     insects voraciously feed on various insect pests. We conducted a comprehensive     survey to study the species composition and host range of predatory coccinellids for ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

From hindrance to indirect protection: Ant‐mediated enemy‐free space for gall midges (Cecidomyiidae) on Macaranga myrmecophytes (Euphorbiaceae)

open access: yesEntomological Science, Volume 29, Issue 3, September 2026.
Ant presence was associated with lower gall density on Macaranga beccariana, whereas trees lacking ant defense had more galls and showed different parasitism patterns. Results from this natural experiment suggest that plant‐ants may indirectly influence gall midges through their effects on multitrophic interactions.

The reproductive behaviour of an aphidophagous ladybeetle, Coccinella septempunctata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2002
The reproductive behaviour of a ladybeetle, Coccinella septempunctata was studied in detail. Males became sexually mature within 8.8 ± 0.3 days at 27°C, while females took 11.2 ± 0.4 days. Males exhibited courtship display in five steps: approach, watch,

Efficacy of Zeolite and Kaolin in the Control of Cacopsylla pyri (L.) (Hemiptera: Psyllidae) and Compatibility With Its Natural Antagonist Anthocoris nemoralis (Fabricius) (Hemiptera: Anthocoridae)

open access: yesJournal of Applied Entomology, Volume 150, Issue 8, Page 1080-1087, September 2026.
ABSTRACT The pear psyllid Cacopsylla pyri is a major pest of European pear orchards, responsible for significant yield losses. Its management is increasingly challenged by restrictions on synthetic active ingredients, resistance development, and the shift towards sustainable production systems.
