Reproductive performance of Coccinella transversalis Fabricius (Coleoptera: Coccinellidae) on different aphid species

Author[s]: ARSHAD ALI, PARVEZ QAMAR RIZVI, AND MAHESH PATHAK

Abstract: 

The reproductive performance of Coccinella transversalis Fabricius was evaluated on five aphid species i.e., Lipaphis erysimi Kaltenbach, Aphis craccivora Koch, Hyadaphis coriandri Das, Rhopalosiphum nymphae Linnaeus and Macrosiphum rosae Linnaeus, under laboratory conditions (251C, 655 % RH and 12 L:12 D). The response of female towards prey consumption and egg production was highest on L. erysimi and lowest on M. rosae. The progeny loss and pre-reproductive period was minimum with regard to L. erysimi. The reproductive period, post-reproductive period, reproductive time ratio, reproductive rate and bioconversion efficiency were significantly maximum on L. erysimi than other aphid species. Among all the aphid species tested, L. erysimi proved to be the most suitable species, sustaining better reproductive performance of C. transversalis.

On the occurrence of certain uncommon bird species from Kadalundy Estuary, Kerala, South India

Author[s]: K.M. AARIF AND S. PRASANTH NARAYANAN

Abstract: 

The Kadalundi Wetland located in Tirur Taluk and comes under the Vallikunnu Panchayat. The Three square kilometres of this wetland were declared as a community reserve area during 2008. On the western side of the railway track, about 8 hectares of mudflats are exposed during low tide when the water level between the busy railway line and the sea mouth recedes, which attracts many birds to the wetland.  The present reports are based on the observations from June 2007 to December 2008.  The present study reported 12 Uncommon Species, Spotted Redshank, Northern Shoveller, Brown Skua and Pamarine Jaeger are new additions to the avifauna of Kadalundy. Wind-blown specimens of oceanic birds, during the south-west monsoon (June-August), are regular on the sea coast of Kerala. The sighting of six such species at Kadalundy again proves this statement.
