Abstract: A new species of the genus Epipteromalus Ashmead viz. E.bengalensis
sp.nov. (Hymenoptera: Pteromalidae) is described from India. The genus Epipteromalus
is reported for the first time from the old world. The affinities of the new
species with the only known species E.algonquinensis Ashmead are also

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 (25±1°C, 65±5 % 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. |
