Japanese Beetle
Popillia japonica Newman (Scarabaeidae, Coleoptera)
A highly destructive invasive beetle with a metallic green body and coppery wing covers. Adults are voracious feeders on foliage and fruit, while larvae damage turf root systems. First introduced in 1916, they have become established across much of eastern North America.

Potential Damage
Lifecycle
Overwinter as third instar grubs 13 cm below soil surface. In spring, grubs move closer to surface and feed on turf roots. After 10-day inactive period, pupation occurs for 8-20 days. Adults emerge mid-May in southern areas, as late as July in northern regions. Adults live 1-1.5 months, with females laying 40-60 eggs in moist soil. Grubs emerge 2 weeks after egg deposition and feed until cold weather. Single generation annually.
Professional Treatment Approach
Early detection through pheromone trapping and monitoring
Systemic insecticide application before adult emergence
Targeted treatment during peak activity periods (mid-July to August)
Grub control in nearby turf areas to reduce beetle populations
Remove beetles by hand in small infestations
Professional diagnosis for large-scale management programs
