Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

open access: yesJournal 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 ...

Chinch Bug-Resistant Buffalograss: An Investigation of Tolerance, Antixenosis, and Antibiosis [PDF]

open access: yes, 2003
Choice and no-choice studies were conducted to determine the categories (antibiosis, antixenosis, and tolerance) of resistance of four buffalograsses (NE91-118, ‘Bonnie Brae’, ‘Cody’, and ‘Tatanka’) previously identified as resistant to the western ...

Antixenosis to the peach/potato aphid, myzus persicae (SuIzer) in potato cultivars

open access: yes, 2003
Field studies were conducted to determine the antixenotic resistance against the peach-potato aphid, Myzus persicae (Sulzer) in different potato cultivars i.e. Cardinal, Ultimus and Desiree. These cultivars were studied in the paired tests as Cardinal vs.

Performance of Wild Tomato Accessions and Elucidation of Resistance against Invasive Pest Phthorimaea absoluta Damage under Tropical Conditions

open access: yesHorticulturae, 2023
Invasive tomato leaf miner, Phthorimaea absoluta causes serious damage and yield loss in tomato production in open-field and protected cultivation. Use of chemical pesticides is uneconomical and adversely affects humans and the environment.

Nitric Oxide and Phytohormone Crosstalk Mediates Soybean Growth and Defence Against Aphis glycines

open access: yesPhysiologia Plantarum, Volume 178, Issue 5, September/October 2026.
ABSTRACT Aphid infestation, particularly by Aphis glycines, poses a major threat to soybean (Glycine max) production, necessitating sustainable defence strategies. This study evaluated the role of nitric oxide (NO) donor S‐nitrosocysteine (CySNO) in enhancing soybean resistance to aphids through hormonal crosstalk.

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

open access: yesJournal 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 ...

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

open access: yesPest Management Science, Volume 82, Issue 8, Page 7951-7960, August 2026.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...

Soil‐Applied Silicon Does Not Affect the Performance of Aphis craccivora on Cowpea Genotypes

open access: yesEntomological Research, Volume 56, Issue 8, August 2026.
ABSTRACT Cowpea (Vigna unguiculata) is an important crop in tropical regions, where infestations of the black aphid, Aphis craccivora Koch (Hemiptera: Aphididae), can significantly reduce productivity. Silicon (Si) fertilization has been proposed as a strategy to enhance plant resistance to herbivores, although its effectiveness varies among plant ...
