Insect pest management in faba beans

Plain text source: 
Beat sheet and sweep net sampling of faba beans both severely underestimate the density of helicoverpa larvae, particularly smaller ones; a visual inspection is critical to improving pest number estimates.. Populations may be exceeding threshold before this is detected," Dr Miles says... Insect damage is not responsible for the majority of defective grain but further analysis is warranted to consider how the pod damage caused by helicoverpa may be contributing to weathering and poor colour in faba beans by allowing entry of fungi and bacteria...
