Description Taxonomic studies on predacious Coccinellidae, Order : Coleoptera
were under taken at the Department of Entomology, S.V. Agricultural
College, Tirupati during 2007-2009. In the present study, 12 Coccinellid
species belonging to eleven genera, under four tribes of the family
Coccinellidae are collected and identified. They, are Brumoides suturalis
(Fabricius), Chilocorus nigritus (Fabricius), Coccinella septempunctata
Linnaeus, Coccinella transversalis Fabricius, Harmonia octomaculata
(Fabricius), Illeis cincta (Fabricius), Micraspis discolor (Fabricius),
Cheilomenes sexmaculata (Fabricius), Propylea sp. nr. japonica (Thunberg),
Pseudaspidimerus trinotatus (Thunberg), Cryptolaemus montrouzieri Mulsant
and Scymnus (Scymnus) nubilus Mulsant.
All the 12 Coccinellid species are described and illustrated. A key for
distinguishing all these Coccinellid species with line diagrams and colour
photographs are given for easy identification.
Among these 12 species of Coccinellids, Coccinella transversalis
Fabricius (38%) and Cheilomenes sexmaculata (Fabricius) (34%) are the most
abundant species in and around Tirupati in different agro-ecosystems followed
by Illeis cincta (Fabricius) (6%). Five species viz., Coccinella septempunctata
Linnaeus; Coccinella transversalis Fabricius; Harmonia octomaculata
(Fabricius); Micraspis discolor (Fabricius) and Cheilomenes sexmaculata
(Fabricius) are recorded in groundnut crop ecosystem feeding on aphids, Aphis
craccivora and leafhoppers, Empoasca (Empoasca) motti Pruthi. Among these
species, Coccinella transversalis Fabricius is abundant recording 52% of
population followed by Cheilomenes sexmaculata (Fabricius) (29%).
