Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
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 ...

Characteristics of Chili (Capsicum annuum L.) That Are Resistant and Susceptible to Oriental Fruit Fly (Bactrocera dorsalis Hendel) Infestation

Horticulturae, 2022
The response of chili (Capsicum annuum L.) to oriental fruit fly infestation (Bactrocera dorsalis) is highly variable among varieties. The differences in the resistance level of chili to oriental fruit fly infestation are presumed to be determined by the

Antixenosis to Chrysodeixis includens (Lepidoptera: Noctuidae) among soybean genotypes [PDF]

Bragantia, 2017
ABSTRACT The soybean looper Chrysodeixis includens is one of the main defoliating pests of soybean cultures in Brazil. This work aimed to evaluate the effect of offering different soybean genotypes to this insect to verify the occurrence of antixenosis. In a greenhouse, assays were carried out to determine the attractiveness of C.

Insect‐resistant soybean genotypes accumulate rutin and its O‐methylated derivative narcissin, a more potent flavonol targeting Anticarsia gemmatalis digestive and detoxification enzymes and reducing larval survival

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5921-5933, 15 August 2026.
Abstract BACKGROUND Soybean underpins Brazil's agricultural, yet its sustainability is threatened by lepidopteran pests such as Anticarsia gemmatalis. Although insect‐resistant cultivars have long been associated with the constitutive accumulation of quercetin‐derived flavonols, the biochemical mechanisms underlying this resistance remain poorly ...

Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, Volume 82, Issue 7, Page 6740-6748, July 2026.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

Drought Stress Promotes Aphis gossypii Growth but Decreases Host Attractiveness in Melon

Journal of Applied Entomology, Volume 150, Issue 6, Page 770-779, July 2026.
ABSTRACT Drought stress is a significant environmental factor that affects plant physiology and growth, leading to considerable detrimental effects on crop productivity. Cucumis melo, which is widely cultivated for its economic value, is particularly susceptible to water scarcity.

The Source of Rag5-Mediated Resistance to Soybean Aphids Is Located in the Stem

Frontiers in Plant Science, 2021
The soybean aphid (Aphis glycines) continues to threaten soybean production in the United States. A suite of management strategies, such as planting aphid-resistant cultivars, has been successful in controlling soybean aphids.

Identification of Genes Involved in Resistance to Flavescence Dorée Disease of Grapevine: A Model Study Using Arabidopsis thaliana

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
Arabidopsis thaliana genes conferring resistance to flavescence dorée (FD) phytoplasma were identified, revealing vector‐independent defence mechanisms and providing potential targets for breeding FD‐resistant grapevine. ABSTRACT Flavescence dorée (FD), caused by FD phytoplasma (FDp) and transmitted by the leafhopper Scaphoideus titanus, is a ...
