Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

open access: yesPest Management Science, Volume 82, Issue 8, Page 7746-7757, August 2026.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Impacts of a Sweet Orange Essential Oil–Based Biopesticide on Exorista larvarum, a Parasitoid Tachinid Fly With a Dual Role

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 933-941, August 2026.
Lethal (mortality) and sublethal (fecundity, fertility) effects of the biopesticide Prev‐Am Plus (containing ~6% sweet orange essential oil) were assessed on the tachinid fly Exorista larvarum. Mated females were exposed via contact and oral routes across five concentrations (0.25%–20%) using protocols adapted from Apis mellifera.

Non‐Target Effects of Some Common Agrochemicals on Various Life Stages and Parasitism Behaviour of Trichogrammatoidea cryptophlebiae Nagaraja, 1979 (Hymenoptera: Trichogrammatidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 8, Page 942-956, August 2026.
This study assessed the non‐target effects of commonly used agrochemicals on the egg parasitoid Trichogrammatoidea cryptophlebiae, an important biological control agent in South African orchards. Agrochemical impacts varied across life stages, with several insecticides allowing adult survival but significantly reducing parasitism and developmental ...

GpaR Drives Type III Secretion and Virulence Through Direct Activation of the HrpG‐HrpX Cascade in Xanthomonas oryzae pv. oryzicola

open access: yesMolecular Plant Pathology, Volume 27, Issue 8, August 2026.
GpaR directly activates hrpG and hrpX, triggering the HrpG–HrpX cascade to promote virulence in rice and induce the hypersensitive response in nonhost plants, revealing a key upstream regulator of type III secretion and pathogenicity in Xanthomonas oryzae pv. oryzicola. ABSTRACT Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of bacterial leaf
