Agricultural 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.

Environment Conservation JournalCoccinellid 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 ...

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 ...

Brazilian Archives of Biology and Technology, 2007 This work evaluated the functional response of adult females of Eriopis connexa to different densities of Macrosiphum euphorbiae and Tetranychus evansi. When preying upon aphids, E. connexa presented a sigmoidal functional response (Type III).

The effect of climate change on an aphid–coccinellid interaction
Global Change Biology, 1997 A model (Carter et al. 1982) that described the population dynamics of Sitobion avenae was modified and extended to include the population dynamics of the aphidophagous coccinellid, Coccinella septempunctata. The model was run under three different temperature regimes, corresponding to different degrees of warmth in typical English summers, and, in ...

Ecological 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.

European Journal of Entomology, 2008 In agro-ecosystems, habitat loss and fragmentation may alter the assemblage of aphidophagous insects, such as foliar-foraging (coccinellids) and ground-foraging predators (carabids), potentially affecting intraguild interactions. We evaluated how habitat

Insect Conservation and Diversity, EarlyView.Land use and climate change are two major environmental pressures that interact to impact insect biodiversity. We compared the impacts of land use alone and of the interaction between land use and climate change on the five major insect orders. Most impacted were the Lepidoptera, showing 91% lower total abundance in sites of high‐intensity agriculture ...
