A South African Scenario: Structure and Function of Peptides of the Adipokinetic Hormone Family of the Brown Locust, Locustana pardalina, and the Putative Role of These Peptides in Plague Management

open access: yesArchives of Insect Biochemistry and Physiology, Volume 120, Issue 2, October 2025.
1. The brown locust produces the three adipokinetic hormones Locmi‐AKH‐I, ‐II and ‐III found also in the migratory locust. 2. Flight is characterised by differential changes in haemolymph carbohydrate and lipid levels. 3. Modelling ligand‐receptor binding is proposed as important step to a new strategy to combat the brown locust.

Evidence of Rapid Evolution in Herbivory Defense Responses With Conserved Trade‐Offs in Populations of Medicago polymorpha

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study uses a historical invasion by Medicago polymorpha (Burr Clover) to test the predictive power of the Shifting Defense Hypothesis (SDH) by investigating variation in plant defenses to herbivorous insects. We compared the feeding preferences of a generalist and a specialist herbivore on native and invasive populations of M.

Life‐History Responses of the Fall Webworm Hyphantria cunea to Temperature Change: Not Following the Temperature–Size Rule

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
The life‐history traits of the fall webworm were examined at 20°C, 22°C, 24°C, 26°C, and 28°C. Larval development time was shorter in males than females at all tested temperatures. Female body weight increased at high temperatures, while male body weight decreased.

Artificial Light at Night Affects Larval Growth Without Altering Survival or Pupation in Spongy Moth (Lymantria dispar dispar)

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
In this study, we investigated how artificial light at night (ALAN) affects larval development in the invasive spongy moth. Caterpillars exposed to 3700 K LED light reached higher body masses than those under 2200 K or darkness, suggesting ALAN may enhance growth and influence population dynamics.
