摘要

The ladybird beetles (Coleoptera: Coccinellidae) have great economic importance as natural enemies. Three hundred individuals belonging to 6 genera and 7 species of the subfamily, Coccinellinae and the tribe, Coccinellini was collected during March-May, 2011 from 3 study sites of Hazara University, Garden Campus, Mansehra, Pakistan. They were reported maximum (83.3%) from residential area and minimum (8%) from administration area. All collected species have glabrous hair on their slightly elongated or rounded bright colored body. The seven-spotted ladybug, Coccinella septempunctata (Linnaeus) has maximum (average: 6.7 ± 0.77 cm;n = 15) and Adalia tetraspilota (Hope) has minimum (average: 4.2 ± 0.15 cm;n = 14) body length. Moreover, transverse ladybird, Coccinella transversalis (Fabricius) has maximum (average: 4.8 ± 0.35 cm;n = 10) and Oenopia sauzeti (Mulsant) (n = 9) or adonis ladybird, Hippodamia variegate (Goeze) (n = 10) has minimum (3.1 cm) body width. Except six-spotted zigzag ladybird, Menochilus sexmaculatus (Fabricius) (n = 12), all collected species have black head, varied but attractive and dark in color pronotum and elytra, black scutellum except in fifteen-spotted ladybird, Harmonia dimidiate (Fabricius) (n = 10) which was brownish. The ventral side of body of A. tetraspilota was dark brown, however, C. septempunctata, C. transversalis, H. variegate and O. sauzeti were black;moreover, H. dimidiata was brownish-orange;further, M. sexmaculatus was brown. It is concluded that ladybird beetles of HU have great diversity. Their further studies have been needed for education and awareness.
