Investigations were carried out in major arecanut growing districts of Karnataka during 2019-2020 to know the species composition of sternorrhynchan pests viz., mealybugs, scales and aphids. A total of 14 species of sternorrhynchan sucking insect pests were recorded in the arecanut growing districts. These belong to five families viz., Coccidae Stephens, Diaspididae Maskell, Pseudococcidae (Heymons) and Aphididae (Buckton). Among these, Coccidae was the species rich. Prococcus acutissimus (Green) was the most predominant species followed by Pseudococcus longispinus (Targioni Tozzetti), Ceroplastes sp. nr. rusci (L.), Chrysomphalus aonidum (L.), Parasaissetia nigra (Neitner), Coccus viridis (Green), Coccus hesperidum L., Pseudaulacaspis cockerelli (Cooley), Pinnaspis aspidistrae (Signoret), Lepidosaphes gloveri (Packard), Ferrisia virgata (Cockerell), Dysmicoccus brevipes (Cockerell) and Cerataphis lataniae (Boisduval). Diagnostics of these with descriptions of taxonomic characters and a key to genera is also provided herein.
