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

Journal 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

Gut Microbiome in Predaceous Coccinellids

We reviewed the recent information on the microbiome of the predaceous coccinellids to understand the functional diversity and positive and negative effects of the microbiome on the ecology of coccinellids. Coccinellids comprise a wide range of microbiomes, primarily consisting of numerous genera of bacteria with different roles as both endosymbionts ...

Impact and selectivity of insecticides on groundnut predators

Environment Conservation Journal
Predatory arthropods play a crucial role in mitigating the impact of insect pests. However, the use of broad-spectrum insecticides in pest management methods can pose a threat to predator populations. In response to the need for safer and more selective

Characterization of a newly established aggregation of the invasive ladybeetle Harmonia axyridis and current status of the invader in Spain

Spanish Journal of Agricultural Research, 2015
The multicoloured Asian ladybeetle, Harmonia axyridis (Pallas), an invasive biocontrol agent introduced in North and South America, as well as in Europe for aphid control, drastically affected assemblages of native coccinellid species, local communities ...

Phylogenetic Analyses of True Ladybirds (Coleoptera: Coccinellidae: Coccinellini) Reveal Directionality in Diet Evolution and Support a Boreotropical Origin of the Tribe

Ecology and Evolution, Volume 16, Issue 4, April 2026.
A newly generated large‐scale molecular phylogeny of true ladybirds (Coccinellini) clarifies their evolutionary relationships and supports a boreotropical origin in the Paleocene, with multiple independent southward dispersals. Ancestral diet reconstructions suggest an initial specialization on aphids, followed by expansions in host range and ...

Corn leaf aphid, Rhopalosiphum maidis (Hemiptera: Aphididae), is a key to greenbug, Schizaphis graminum (Hemiptera: Aphididae), biological control in grain sorghum, Sorghum bicolor

European Journal of Entomology, 2008
In the sorghum/aphid/ladybeetle ecosystem found in the Texas High Plains Region of the United States, we found that the corn leaf aphid, Rhopalosiphum maidis (Fitch), is a key aphid species that provides a critical early-season food source for native ...

The pool of Coccinellids (Coleoptera: Coccinellidae) to control Coccids (Homoptera: Coccoidea) in Portuguese citrus groves

, 1999
International audienceThe study of coccinellids for the biological control of those pests was undertaken. This paper aimed firstly to determine which coccidophagous ladybirds are more likely to control coccids by examining Dominance, Constancy and ...
