The colonization of Chilocorus kuwanae (Silvestri) (Coleoptera: Coccinellidae) and Cybocephalus nipponicus (Endrody-Younga) (Coleoptera: Nitidulidae), introduced predators of euonymus scale, Unaspis euonymi L., was evaluated on evergreen euonymus scale, Euonymus japonica L., by regional and statewide surveying. This study determined the statewide distribution of the native parasites of euonymus scale, Aspidiotiphagus spp. and Encarsia spp. (Hymenoptera: Aphelinidae). Highest recovery incidences were from 18 of the 41 survey sites on 25 May. The survey established the survival and dispersal of C. kuwanae in metropolitan areas of Virginia with recoveries in 8 of the 12 cities.

Abstract Chilocorus kuwanae (Sylvestri) was imported from Korea to the United States for release against the euonymus scale (Unaspis euonymi (Comstock)). Field observations suggest that C. kuwanae feeds on a number of other armored scale insects, including white peach scale (Pseudaulacaspis pentagona (Targionni-Tozzeti)) and obscure scale (Melanaspis obscura (Comstock)). However, such observations have not been rigorously examined under controlled conditions. Our laboratory investigations indicate that C. kuwanae survives and reproduces well on San Jose scale (Quadraspidiotus perniciosus (Comstock)), in addition to euonymus scale. Fecundity was reduced in adults fed white peach scale. Few larvae survived to adulthood when fed oleander scale (Aspidiotus nerii (Bouche)). Adults failed to reproduce on obscure scale; none of the larvae fed this host survived to the pupal stage.

The Subject

Although ladybirds of European Russia and the Caucasus have been the subject of numerous ecological and faunistic investigations, there is an evident lack of appropriate identification keys. New, original keys to subfamilies, tribes, genera, and species of ladybirds (Coccinellidae) of European Russia and the Russian Caucasus are presented here. The keys include all native species recorded in the region and all introduced alien species. Some species from adjacent regions are added. In total, 113 species are treated and illustrated with line drawings. Photographs of rare and endemic species are provided. Information on the distribution of species within the region under consideration is provided. Chilocorus kuwanae Silvestri, 1909 is recognized as a subjective junior synonym (syn. nov.) of Ch. renipustulatus (Scriba, 1791).

Taxonomical Revision

The ladybug Chilocorus kuwanae, which was described in Japan, has been used for biological control of pests for 100 years. Chilocorus kuwanae was recently synonymized with Ch. renipustulatus described in Europe. The synonymy was based on the examination of few specimens. Our aim is to verify this synonymy. We studied all characters previously used to distinguish these taxa: eight metric and nine qualitative characters. Examination of 107 specimens from Japan and Sakhalin and 174 specimens from Europe showed that the ranges of variability in all characters in Asian and European specimens strongly overlap. There are no characters with interspecific hiatuses. Analysis with Amadon’s criteria showed that Asian and European specimens also do not represent different subspecies. Conclusions: (1) No differences between the specimens from Asia (Japan and Sakhalin) and Europe were found at specific or subspecific levels. Chilocorus kuwanae is a junior synonym of Ch. renipustulatus. (2) The releases of “Chilocorus kuwanae” in Europe and the Caucasus did not represent classical biological control since the same species was native to these regions. (3) A thorough taxonomical revision with the study of morphological variability should be conducted before the introduction of any species to new regions. (4) Taxonomical conclusions based on morphological studies should be confirmed by statistical methods.
