Aboveground and Belowground Insect Herbivory Changes Maize‐Wireworm Interactions via Root Volatile Cues

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere harbours critical plant‐herbivore interactions often mediated by small lipophilic molecules (SLMs). Despite the agricultural importance of many soil‐dwelling insects, surprisingly little is known about chemically mediated belowground crop‐pest interactions. Root and shoot herbivores can influence these interactions by modifying

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, Volume 82, Issue 7, Page 7123-7136, July 2026.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

Mitochondrial DNA analysis of field populations of Helicoverpa armigera (Lepidoptera: Noctuidae) and of its relationship to H. zea

BMC Evolutionary Biology, 2007
Background Helicoverpa armigera and H. zea are amongst the most significant polyphagous pest lepidopteran species in the Old and New Worlds respectively. Separation of H. armigera and H. zea is difficult and is usually only achieved through morphological

Multiple recombination events between two cytochrome P450 loci contribute to global pyrethroid resistance in Helicoverpa armigera. [PDF]

PLoS ONE, 2018
The cotton bollworm, Helicoverpa armigera (Hübner) is one of the most serious insect pest species to evolve resistance against many insecticides from different chemical classes.

Drought and Herbivory Drive Physiological and Phytohormonal Changes in Soybean (Glycine max Merril): Insights From a Meta‐Analysis

Plant, Cell &Environment, Volume 49, Issue 7, Page 4041-4053, July 2026.
ABSTRACT With climate change, abiotic and biotic stresses such as drought and herbivory are predicted to further diminish agricultural productivity. Soybean (Glycine max [L.] Merrill), a crop of global economic importance, is vulnerable to both. However, the interactive effects of drought and herbivory on soybeans haven't been explored, especially ...

Henbit is an attainable cover crop

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Henbit is a short‐season plant that grows through the winter. It seeds itself in the spring with seeds that stay dormant through the summer and germinate in the fall. Winter growth makes henbit a good cover crop for the offseason of summer cash crops. Abstract Henbit (Lamium amplexicaule L.) is a potential cover crop in the Central United States, but ...

Movement and Survival of Spodoptera litura (Lepidoptera: Noctuidae) Neonate Larvae on Cotton Expressing Bacillus thuringiensis Proteins

Entomologia Experimentalis et Applicata, Volume 174, Issue 6, Page 549-558, June 2026.
Spodoptera litura neonates showed increased movement on Bt‐expressing Bollgard 3 (BG) cotton leaf discs but did not initially avoid it. Survival was higher when larvae could move from BG3 to non‐Bt leaf discs. On whole plants, more larvae dispersed from hatching on BG3 cotton compared to non‐Bt cotton. These findings suggest the larval movement differs

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

Plant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.
