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

Entomologia 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 ...

Nutritional Stress Modulates Developmental Thresholds in a Male Dimorphic Mite

Entomologia Experimentalis et Applicata, EarlyView.
Global warming can alter nutrition during development, but whether this affects phenotype expression solely through changes in condition or also through developmental decision‐making remains unclear. In the male‐dimorphic bulb mite Rhizoglyphus robini, nutritional stress shifted the developmental threshold for fighter versus scrambler expression and ...

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

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.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Dragonfly taxonomic and functional responses to urbanized streams in southeastern Europe, with management recommendations

Insect Conservation and Diversity, EarlyView.
Urbanization drives turnover in dragonfly species composition, traits, and habitat conservation value. Natural stream sections have a higher conservation value (higher DBI) due to presence of specialists. Properly managed urban streams can support diverse dragonfly assemblages.

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

Journal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.
