Moths are less attracted to light than they used to be
A new study produces evidence showing that light traps for moths are becoming less effective over the past 25 years. They use data on one pest species, the Corn Earworm (Helicoverpa zea), for which the moth's prevalence over time has been monitored using light traps (using fluorescent black-light bulbs) and pheromone traps operating in close proximity.
