Dietary Stress From Plant Secondary Metabolites Contributes to Grasshopper (Oedaleus asiaticus) Migration or Plague by Regulating Insect Insulin-Like Signaling Pathway

open access: goldFrontiers in Physiology, 2019
Diets essentially affect the ecological distribution of insects, and may contribute to or even accelerate pest plague outbreaks. The grasshopper, Oedaleus asiaticus B-Bienko (OA), is a persistent pest occurring in northern Asian grasslands. Migration and

How often are ecosystems top‐down controlled? Experiments in grassland, grasshopper, and bird systems over time and space [PDF]

open access: yesEcosphere
Ecosystems are frequently considered to be controlled by predation (top‐down). Experiments examined this in four bird/spider/grasshopper/prairie habitats over 34 years, employing in each habitat three 100 m2 bird exclosures and controls (121 habitat/year
