Effects of High-Level Acylsugar-Producing Tomato Lines on the Development of Tomato Psyllids (Hemiptera: Triozidae). [PDF]

open access: yes, 2019
Acylsugars have been shown to provide activity against numerous insect pests of tomatoes. Comparison of acylsugar levels in four tomato plant lines, FA7/AS, FA2/AS, CU071026, and 'Yellow Pear', found that the acylsugar contents in the elevated acylsugar ...

The Effects of LED Daylength Extensions on the Daily Activity Patterns of a Greenhouse Biological Control Agent, Aphidius matricariae

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 5, Page 398-410, May 2026.
We used automated activity monitors to examine how light‐emitting diode illumination affects the daily locomotor activity of the parasitoid biocontrol agent Aphidius matricariae. We compared 4‐ to 20 h broad‐spectrum white (BSW) photoperiods, and 12 h BSW photoperiods extended with an additional 6 h of red‐blue, red‐green‐blue, or BSW light, or no ...

Feeding Preference and Foraging Behaviour of Eriopis connexa on Two Aphid Species

open access: yesJournal of Applied Entomology, Volume 150, Issue 4, Page 444-453, May 2026.
ABSTRACT Aphids are phloem‐feeding insects that cause both direct and indirect damage to crops, reducing agricultural productivity. Among the available pest control strategies, biological control using natural enemies is a sustainable and effective approach. The ladybird Eriopis connexa (Germar, 1824) is a generalist predator known for its voracity and

Beneficial rhizobacteria and virus infection modulate the soybean metabolome and influence the feeding preferences of the virus vector Epilachna varivestis

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2599-2618, May 2026.
Summary Beneficial rhizobacteria and viral pathogens can both alter host plant phenotypes, yet little is known about how their simultaneous presence influences plant metabolism and species interactions. We investigated how two rhizobacteria, Bradyrhizobium japonicum and Delftia acidovorans, together with bean pod mottle virus (BPMV), shape soybean ...

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

open access: yesPlant Biotechnology Journal, Volume 24, Issue 5, Page 2939-2955, May 2026.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.
