The mature larva and pupa of are described and illustrated with complete chaetotaxy for the first time. Five larval instars and the factors for larval growth are determined, and the larval development of this species is comprehensively described. In order to confirm species affiliation, selected larvae were subjected to genetic analysis (mtCOI).

View Article and Find Full Text PDFA couple of different members of the coleopteran genus Otiorhynchus (Coleoptera: Curculionidae) are becoming increasingly important as pests of nursery and ornamental plants in global horticulture. Although adult weevils are morphologically distinguishable by skilled personnel, high potential for misidentification is given for cryptic larval stages. For developing and applying efficient pest management strategies the determination of the respective species is however a prerequisite, because each species may have a different phenology or a varying susceptibility to pesticides.
