Cydalima perspectalis

Box tree moth (Cydalima perspectalis)
Latin Name Cydalima perspectalis
Common Name Box tree moth
Biology

A moth of the Crambidae family. Multivoltine (multiple generations/year). Larvae feed on leaves, with 5-6 instars. Pupation occurs in leaf litter or silk cocoons. Adults are active at dusk.

Damage

Severe defoliation of Buxus species (boxwood), leading to plant stress, dieback, or death. Repeated infestations weaken plants.

Distribution Regions

Native to East Asia (China, Korea, Japan); invasive in Europe, North America, and parts of South America.

Monitoring

Pheromone traps using specific sex pheromones; visual surveys for defoliation and larval webs.

Recommended Traps

Delta traps or bucket traps baited with C. perspectalis sex pheromone lures.

Literature review

Semiochemical evidence

The cited publications support the exact compound-species relationship. Formulation, ratio, loading, release rate and field lifetime depend on a validated lure protocol and are not inferred here.
