Identification and Behavioral Evaluation of Sex Pheromone in Xanthopimpla pedator (Fabricius)—A Serious Pupal Parasitoid of Tropical Tasar Silkworm Anthereae mylitta Drury

Hayati Journal of Biosciences, 2016
Xanthopimpla is a major parasitoid of silk worm cocoons. The female Xanthopimpla pedator (Fabricius) lays the eggs in male cocoons. Control of this infestation with pesticides is not recommended because of its concealed behavior.

Determination of Rice Accession Status Using Infochemical and Visual Cues Emitted to Sustainably Control Diopsis apicalis Dalman

Insects
This study assessed the host plant selection behavior of female stalk-eyed flies (SEFs) or Diopsis apicalis, where a Y-tube olfactometer was used to compare SEF attraction to the odor of leaves from four rice varieties (ITA306, WAB56-104, CG14, and RAM55)

Chemical Composition and Biological Activities of Croton sertanejus Essential Oil Against Aedes aegypti and Preliminary Toxicity in Mus Musculus

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
This study investigated the chemical composition and biological potential of the essential oil from the newly described species Croton sertanejus. The results demonstrated efficacy in repellency and oviposition deterrence against the Aedes aegypti mosquito, coupled with low mammalian toxicity, suggesting the potential of this oil as a viable ...

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, Volume 82, Issue 9, Page 8499-8511, September 2026.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Transfer of Potentially Toxic Metal(loid)s From Ultramafic Soils in a Tri‐Trophic Food Chain Experiment

Ecological Research, Volume 41, Issue 5, September 2026.
Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant‐herbivore‐predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM‐enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by ...

The Potential for Pest Management Using Plant‐Derived Signaling Compounds

Ecological Research, Volume 41, Issue 5, September 2026.
Plant‐derived signaling compounds mediate ecological interactions among plants, herbivores, their natural enemies, and neighboring plants. This graphical summary highlights three approaches to leveraging such ecological interactions for environmentally benign pest management: (1) Recruitment of natural enemies: Using herbivory‐induced plant volatiles ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, Volume 150, Issue 8, Page 1102-1114, September 2026.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...
