Planthopper protein Nlsp5 is essential for salivary sheath formation and acts as a HAMP inducing plant resistance to insects

open access: yesPlant Biotechnology Journal, Volume 23, Issue 9, Page 4076-4091, September 2025.
Summary During herbivore feeding, plants can recognize herbivore‐associated molecular patterns (HAMPs) present in saliva and trigger pattern‐triggered immunity (PTI). Piercing‐sucking insects secrete gel saliva, forming salivary sheaths that aid in feeding. However, the role of proteins within these salivary sheaths in modulating plant defences remains

ANTIBIOSIS AND ANTIXENOSIS IN TOMATO GENOTYPES AGAINST Helicoverpa armigera HUBNER

open access: yesTropical and Subtropical Agroecosystems
<p><strong>Background</strong>. Farmers rely on the use of synthetic insecticides in managing <em>Helicoverpa</em> <em>armigera</em>, hole-boring insect pest on tomato, but they are detrimental to human health. Therefore a more reliable and ecofriendly control measure is needed such as host plant resistance< ...

Contribution of awns and hairy glumes in spring wheat to resistance against wheat midge, Sitodiplosis mosellana

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 781-793, July 2025.
Wheat morphological traits had no consistent impact on Sitodiplosis mosellana oviposition. Differences in the number of eggs among doubled haploid wheat lines were not associated with the presence (A+) or absence (A−) of awns, or the presence (H+) or absence (H−) of hairs in controlled laboratory experiments and field trials.
