The Japanese beetle (JB), Popillia japonica Newman, is a major pest of ornamentals and turf in the Northeast. Daily collections of JB adults from pheromone plus floral scent lure traps indicated that JB adults are particularly active from mid-July through mid-August and that populations peak in late July. Dissections of adult reproductive systems indicated that, while systems develop quite rapidly, JB were not fully mature when they first emerged from the soil and initiated flight. The majority of adults were not fully mature until mid-August, and oviposition appeared to peak at that time. Eggs were recovered from turf samples in early September, first instars were recovered in October, and second instars were recovered in April, indicating that at least a portion of the population (ca. 10%) required 2 years to complete its development.
