Study reveals optimum time to apply eco-friendly biopesticides to tackle Oriental migratory locust pest

Researchers from the Chinese MARA-CABI Joint Laboratory have discovered the optimum time to apply safer-to-use biopesticides to fight the Oriental migratory locust pest. The study, published in Frontiers in Physiology, found that applying biopesticides on younger locusts at dawn or dusk is most effective due to lower body temperatures.

Do forest trees really “talk” through underground fungi?

Researchers found no strong evidence that underground fungal networks, known as common mycorrhizal networks (CMNs), offer benefits to trees and their seedlings. While CMNs exist, there is limited understanding of their structure and function in the field, leading to questionable claims about resource transfer and seedling survival.
