Not known to transmit any human or animal pathogens.

Not known to vector any pathogens or be associated with other organisms.

Separate traps by at least 20 meters (65 feet).

Place traps on a 5 ft. pole (bucket traps will be roughly 4 ft. off the ground).

Whenever possible, place traps in the shade and close to Buxus plants (traps should not touch foliage).

The red large plastic delta trap (LPDT) may be used in areas where the plastic bucket cannot be used due to restrictions on the insecticidal strip or endangered species concerns such as the rusty patched bumble bee (RPBB). Two 3mg pheromone lures are required when using the red LPDT.

Attaching lures to traps

IMPORTANT: Do not include lures for other target species in the trap when surveying for this target.

When using the large plastic delta trap, surveyors must use two 3mg lures per trap (total of 6mg of lure). The load rate of pheromone in each lure is 3 mg. 3 mg lures will be clearly labeled to differentiate them from older 1mg lures. Previously provided 1 mg lures may be used by adding three lures to the lure basket to equal a total of 3 mg.

A Likelihood of Establishment Map is now available. This survey should only be considered in the states with appropriate conditions and suitable hosts for this moth.

The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from the PPQ-S&T Plant Pest Risk Analysis (PPRA) Laboratory.

The SAFARIS team used a likelihood of establishment model for box tree moth occurrence in the continental United States to support CAPS survey planning. The model predicts the suitability of an area for box tree moth occurrence based on the likelihood of three favorable conditions for the disease occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.

Adult emergence time varies with location. In Germany, adult moths can be caught in traps from June until October, with the first generation starting in June and the second generation starting in August or September (Göttig and Herz, 2017). In a study in China, the first generation emerged in mid-May, the second in early July, the third in late September, and the fourth in late November (Wang, 2008). In Japan, adults of the overwintering generation begin to emerge in mid-May, the second generation starts to emerge in late July, and the third in late August. In Japan, the two summer generations required 610-620 DD to complete development and a minimum developmental threshold of 10.5 °C/50.9 °F (Maruyama and Shinkaji, 1987).

Conduct surveys where boxwood is grown or sold, and/or if larvae are seen feeding on foliage. This includes but is not limited to landscaped plantings, nurseries and wholesale, and retail distributors.

Cydalima perspectalis is the only species of Cydalima that has been detected in North America.

Several Diaphania species are present in North America and have wing patterns that are similar to C. perspectalis. Please see the pest datasheet for a complete list of similar looking moths.
