Generation cycles in experimental populations of a multivoltine insect

Journal of Animal Ecology, Volume 95, Issue 5, Page 782-794, May 2026.
Although theory suggests various mechanisms by which environmental and ecological factors may drive generational fluctuations, our field‐cage experiment is the first to demonstrate how internal dynamics and external disturbances jointly produce synchronised, large‐scale outbreak cycles.

Breeding cold‐tolerant Orius laevigatus lines improves thermal tolerance and body size: implications for biological control

Pest Management Science, Volume 82, Issue 4, Page 3011-3018, April 2026.
Biological control agents performance is influenced by temperature. Two cold‐tolerant lines of O. loevigatus were developed, improving their fitness at both low and high temperatures, offering advantages far augmentative biological control. Abstract BACKGROUND The performance of biological control agents (BCAs) is strongly influenced by environmental ...

Discovery of murayaquinone from an endophytic bacterium Streptomyces sp. AN140557 as a potent inhibitor of the pine wood nematode, Bursaphelenchus xylophilus

Pest Management Science, Volume 82, Issue 2, Page 1765-1775, February 2026.
Murayaquinone isolated from the pine endophyte Streptomyces sp. AN140557 exhibits potent, dose‐dependent nematicidal activity and egg‐hatching inhibition against the pine wood nematode. It effectively inhibited pine wilt disease in greenhouse tests, suggesting potential as a promising biocontrol agent.
