Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner

Journal of Applied Entomology, EarlyView.
ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

Response of Ants to the Leafhopper Dalbulus quinquenotatus DeLong & Nault (Hemiptera: Cicadellidae) and Extrafloral Nectaries Following Fire

Sociobiology, 2014
Previous investigations of mutualistic associations between ants and plants bearing extrafloral nectaries (EFNs) or between ants and trophobiont leafhoppers have studied these relationships separately, but nothing is known on how ant abundance responds ...

Faunistic Study of Auchenorrhyncha in Olive Orchards in Greece, Including First Records of Species

Agronomy
The study of Auchenorrhyncha species composition in Greek olive orchards is crucial due to the potential threat of Xylella fastidiosa invading the region. Recent studies have begun exploring agricultural landscapes, particularly olive and citrus orchards.

Development of PCR, LAMP and HRM‐Based Molecular Species Diagnostic Tools for Identifying Four Agricultural Pests in the Genus Helicoverpa (Lepidoptera: Noctuidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Within the subfamily Heliothinae, the genus Helicoverpa comprises several highly destructive agricultural pests, including H. armigera, H. assulta, H. punctigera and H. zea. These species cause significant global crop losses due to their wide host range, long‐distance migratory behaviour, and potential for interspecific hybridization.

The BAHD Acyltransferase Gene Family: Evolutionary Dynamics, Biochemical Mechanisms, and Roles in Plant Stress Adaptation

Plant Biotechnology Journal, EarlyView.
BAHD acyltransferases drive metabolic diversification in plants by coupling conserved catalytic scaffolds with regulatory flexibility, enabling stress adaptation and ecological specialisation. ABSTRACT BAHD acyltransferases constitute one of the most versatile enzyme superfamilies in plants, catalysing the acylation of alcohols, amines, polyamines, and

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Identification d'insectes vecteurs "potentiels" du Cape Saint Paul Wilt sur le cocotier au Ghana par PCR [PDF]

, 2008
Le vecteur du phytoplasme responsable du jaunissement mortel du cocotier au Ghana est inconnu à ce jour. Il est cependant admis que les phytoplasmes sont transmis par des insectes piqueurs-suceurs, ces insectes étant supposés être les seuls à avoir la ...

Host plant richness and abundance drive populations of a super‐generalist xylem‐feeding insect

Ecological Entomology, Volume 51, Issue 3, Page 570-579, June 2026.
Philaenus spumarius abundance was assessed across 93 sites and four habitat types (olive groves, vineyards, meadows, and field margins) within eight heterogeneous agricultural landscapes over the year. In spring, nymph abundance was positively associated with herbaceous plant species richness and vegetation cover, highlighting that even super ...
