Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

Environmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Leaf‐chewing but not sap‐feeding herbivores create soil legacies that shape plant resistance through trait‐mediated, guild‐specific effects in Baccharis salicifolia

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory can affect the soil microbiome, creating legacies that affect plant resistance, but how these effects vary by feeding guild and the plant traits involved remain underexplored. We tested how soil legacies created by a leaf‐chewing caterpillar (Spodoptera exigua)

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Ant–aphid mutualism: the influence of Tapinoma ibericum (Hymenoptera: Formicidae) on Aphis gossypii (Hemiptera: Aphidae) control by commercial and spontaneous natural enemies

Insect Science, EarlyView.
The mutualism between Tapinoma ibericum ants and Aphis gossypii disrupts the biological control exerted by Aphidius colemani in greenhouse peppers. Ant exclusion increased parasitism and the presence of most natural enemies, although Aphidoletes aphidimyza was more abundant with ants.

The Spatial Pattern of Aphis gossypii οn Cotton

ENTOMOLOGIA HELLENICA, 2017
The spatial distribution of Aphis gossypii (Glover) on cotton was studied by using Taylor’s power law, the negative binomial parameter k and the iδ-index of aggregation. Both k and iδ were related to density with curvilinear relationships and indicated that aggregation decreases as density increases up to densities of, approximately, two individuals ...

Competitive Interactions Between Generalist Predators and Their Effects on Shared and Non‐Shared Pests in a Greenhouse Crop

Entomologia Experimentalis et Applicata, EarlyView.
Orius laevigatus engages in unidirectional intraguild predation on Transeius montdorensis. Despite this, both predators coexisted and suppressed the shared thrips prey. Aphids, a non‐shared prey, were effectively controlled by O. laevigatus even when its population was limited due to intraguild predation. T.

Quantifying Imidacloprid Susceptibility in Populations of Aphis gossypii

, 2020
Aphis gossypii Glover is a highly polyphagous pest that causes economic losses to many crops worldwide. Evolution of resistance to insecticides is a major concern when managing populations of A. gossypii, and resistance has been reported in numerous studies.

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

Journal of Applied Entomology, EarlyView.
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
