Assessing the Impact of a Boxwood Moth (Cydalima perspectalis, Lepidoptera, Crambidae) Invasion on the Fauna of Millipedes (Diplopoda) in the Caucasian Biosphere Nature Reserve

Changes in the species composition and numbers of diplopods in the boxwood area of a yew–boxwood grove resulting from an invasion of the boxwood moth were studied. Data from before the invasion and several years after it were compared. The disappearance or reduced numbers of some species, as well as changes in the dominant and subdominant species, were revealed in the study area. A statistically significant decrease in the alpha diversity as measured by the Shannon index and changes in the beta diversity and abundance of individual species were demonstrated.
