How do parasites and predators choose their victim? A trade‐off between quality and vulnerability across antagonistic interactions

open access: yesBiological Reviews, Volume 100, Issue 5, Page 2099-2115, October 2025.
ABSTRACT From blood‐sucking lice and food‐stealing gulls to pandemic‐inducing viruses and egg‐eating snakes: parasites and predators are ubiquitous in shaping ecology and evolution. Fundamental to these interactions is the way in which parasites and predators choose their victim. Here, I argue that a trade‐off between host quality and vulnerability can

Registration of two Arachis hypogaea x A. diogoi introgression lines

open access: yesJournal of Plant Registrations, Volume 19, Issue 3, September/December 2025.
Abstract Two (2n = 4x = 40) peanut (Arachis hypogaea L.) germplasm lines, GP‐NC WS 18 (IL‐29) (Reg. no. GP‐254, PI 708341) and GP‐NC WS 19 (IL‐49) (Reg. no. GP‐255, PI 708342), originated from interspecific hybridization between Gregory (2n = 4x = 40; AABB genomes; PI 608666) and A. diogoi Hoehne (2n = 2x = 20; AA genome) (GKP 10602; PI 276235).

Influence of Bt and environmental factors on Fusarium ear rot in maize

open access: yesCrop Science, Volume 65, Issue 4, July/August 2025.
Abstract Fusarium verticillioides is responsible for Fusarium ear rot (FER) and fumonisin (FUM) in maize (Zea mays L.). Multiple factors, including drought stress, humidity, and insects, influence the severity of FER and FUM. This study aimed to assess the occurrence and severity of FER, FUM, and corn earworm (Helicoverpa zea Boddie) feeding in Bt ...

Evaluation of GS‐omega/kappa‐Hxtx‐Hv1a and Bt toxins against Bt‐resistant and ‐susceptible strains of Helicoverpa zea (Boddie) and Spodoptera frugiperda (J.E. Smith)

open access: yesPest Management Science, Volume 81, Issue 7, Page 3565-3572, July 2025.
The addition of 10 μg cm−2 of Cry1Ac to the surface of GS‐omega/kappa‐Hxtx‐Hv1a (ω/κ‐Hv1a) incorporated diet can significantly increase the mortality of Cry‐resistant Helicoverpa zea compared to diets without the Cry1Ac toxin. Abstract BACKGROUND Helicoverpa zea and Spodoptera frugiperda are destructive insect pests of cotton and corn.
