malnad and coastal areas. White grubs are the most important pests on this crop and cause considerable yield loss. Surveys were conducted to record species that are infested with white grubs of Karnataka and Kerala states. Three species of white grubs were collected and described using morphological and molecular characters. A detailed study of male genitalial structures such as aedeagus and endophallus in three species of Leucopholis Dejean, 1833 (Coleoptera: Scarabaeidae: Melolonthinae) viz., Leucopholis lepidophora Blanchard, 1850, Leucopholis burmeisteri Brenske, 1894 and Leucopholis coneophora Burmeister, 1855 showed substantial differences. The mitochondrial cytochrome oxidase subunit I gene was sequenced for molecular identification and phylogenetic analysis in this respect. L. lepidophora, L. burmeisteri and L. coneophora species were successfully identified by employing COXI gene. Phylogenetic analyses revealed that the COXI DNA barcode fragment of Leucopholis species and out-group taxa, available in genetic databases, confirms the species identity.

Western Ghats of Karnataka, an important biodiversity hot spot in the world, rich in insect fauna includingtermites. Diversity of termites from this region poorly understood. In the present study, we have redescribed 12species and termites belonging to two families viz., Rhinotermitidae and termitidae based on morphological andmolecular differences employing mitochondrial 16s rRNA. Further we have employed Bayesian inference inorder to understand phylogenetic relationships among different termite species studied. The integrative taxonomicapproach was successful in delimiting the species studied in the present investigation.

Extracts of Cissus quadrangularis L. were tested for antioxidant activity by b-carotene linoleicacid model and also by 1,1-diphenyl-2-picrylhydrazyl model. The ethyl acetate fraction ofboth fresh and dry stem extracts at a concentration of 100 pm showed 64.8% antioxidant ac-tivity in the b-carotene linoleic acid system and 61.6% in the 1,1-diphenyl-2-picrylhydrazylsystem. This fraction showed the presence of sterols, vitamin C, and tanins as phytocon-stituents. The antioxidant activity of methanol extract and aqueous extract were comparativelyless significant than that of ethyl acetate extract, and n-hexane extract showed the least ac-tivity. The ethyl acetate extract and methanol extract of both fresh and dry stems further ex-hibited antimicrobial activity against Gram-positive bacteria, including Bacillus subtilis,Bacillus cereus, Staphylococcus aureus , and Streptococcus species. The results of the studyhave implications in the use of C. quadrangularis as an antibacterial agent and more so as anantioxidant in several aplications requiring these properties.9
