Sukanya Bandyopadhyay | Tapan Kumar Chatterjee [6]
Abstract: The present study was conducted a qualitative and quantitative assessment of diversity of visiting insects on flower of mustard (Brassica sp.) in Ghatal area, West Bengal, India. The insect and butterfly species diversity indices such as total specimens (N), Shannon diversity index (H'), Index of Dominance (C), Berger-Parker Dominance Index, and Margalef?s species richness index (S) and Gini coefficient (G) index were calculated. There were about 18 types of varieties of species recorded. The Hymenoptera recorded majority of species and moderate species under Diptera and minimum species under Odonata and Lepidoptera were obtained. Different diversity indices indicated that total of about 4272 nos. of organisms were recorded. Different indices such as Shannon diversity index, Index of Dominance, and Margalef species richness index, Berger-Parker Dominance Index and Gini coefficient value 2.30, 0.88, 0.21, 2.00 and 0.55, respectively were observed. It is concluded that the mustard flowers attract multiple insect species especially those belonging from Hymenoptera, Diptera and Odonata, and also some species of butterflies and these help pollination to better yield of mustard crop. Future study should be emphasized on the soil condition and the accumulation of metal (loids) and insecticides in this crop specimen due to the application of pest control method.
