Neopulvinaria innumerabilis (Rathvon, 1854), a new species of Coccidae in Serbia

Keywords: cottony maple scale, Coccidae, natural enemies, Serbia

Abstract


In 2016, the species Neopulvinaria innumerabilis (Rathvon, 1854), belonging to the scale
insect family Coccidae, was for the first time found in Serbia, in the location Radmilovac
on Cornus sanguinea L. It reproduces by gamogenesis, develops one generation annually,
and overwinters as a fertilized female on the trunk or branches of its host plant. During this
research, the species was detected on five host plants at six locations in Serbia. It feeds by
sucking sap from leaves, young shoots and branches of infested plants, causing desiccation of
leaves and individual twigs. Four species of its natural enemies were collected and reared from
colonies of N. innumerabilis. Two species of parasitoid wasps, Coccophagus lycimnia (Walker)
(Aphelinidae) and Metaphycus hageni Daane and Caltagirone (Encyrtidae), were found, while
the ladybird Exochomus quadripustulatus L. (Coccinellidae) and the fly Leucopomyia silesiaca
(Egger) (Chamaemyiidae) were identified as predators. The most abundant entomophagous
species was L. silesiaca.
