Do birds benefit crops by eating pest insects? Or are birds the pests for eating those very crops themselves? A new review in the open-access Journal of Integrated Pest Management examines the latest science on understanding how birds impact farm fields and how they factor into IPM programs.
A proof-of-concept study shows insect eggs can be marked with protein that can be later detected in a gut-content analysis of arthropod predators that fed on the eggs. Researchers say the method has applications in biological control and beyond.
