Temporal variation in abundance of male and female spruce budworms at combinatory associations of light traps and pheromone traps
Abstract A 3‐year study (2014–2016) was conducted at Rocky Harbour near the west coast of Newfoundland, Canada, to record the abundance and phenology of adult spruce budworms captured at traps, using a factorial design (light traps and pheromone traps deployed contiguously or segregated spatially)....
