Leaf-footed bugs <i>Coreus marginatus orientalis</i> Kir. and <i>Molipteryx fuliginosa</i> Uhl. (Heteroptera, Coreidae) – pests of cultivated Roses (Rosaceae) in the Primorsky Territory

Abstract

The data on biology and ecology of bed bugs Coreus marginatus orientalis and Molipteryx fuliginosa (Heteroptera, Coreidae), which have become serious pests in anthropo- and agrocenoses of the south of the Russian Far East for the last 10 years, are presented. The purpose of the study is to summarize the observation data on these species as pests of cultivated Rose species in the Primorsky Territory. The studies were carried out from May to October 2007–2022: material collection of hemipterans, observations in natural habitats and stationary conditions were conducted. M. fuliginosa was observed in the cultivated areas of the Ussuriisky urban district on Rosa acicularis, R. rugosa, R. davurica, Rubus komarovii, R. crataegifolius used in landscaping. Cases of bed bugs feeding, sucking sap from vegetative parts of the plants and seedballs were recorded. C. m. orientalis was found on homestead plots in the Chuguevsky, Oktyabrsky, Khankaisky districts and the Ussuriisk urban district. It was collected on the bushes of Rubus idaeus, R. caesius, which are common feeding sites for C. m. orientalis and M. fuliginosa. Aggregation, copulation and oviposition of these insects occur on the cultivated plants. As a result of the infestation of plants by M. fuliginosa, normal development of leaf plates is disturbed, wilting of the apical part of shoots is observed. When C. m. orientalis feeds on raspberry seedballs, damage to the flower disc and desiccation of the drupes occur.
