Studies on host range of Micromus igorotus Banks, a predator of Ceratovacuna lanigera Zehntner indicated that the pupation was higher when aphids belonging to subfamily Hormaphidinae were used as food. Within subfamily Aphidinae, tribe Aphidini was preferred to Macrosiphini. Irrespective of instars of aphid, Aphis craccivora Koch was fed in significantly higher numbers than C. lanigera. Total feeding potential was also significantly higher on A. craccivora of adults. Feeding potential was significantly higher on Aphis gossypii Glover and lower on Pseudoregma bambusicola (Takahashi) and C. lanigera. Pre-oviposition period was significantly longer when adults were reared on A. gossypii. The predator laid maximum eggs when fed with P. bambusicola while least eggs were laid when C. lanigera was provided as prey. Egg and larval periods did not differ significantly on different aphid species, however, pupal period was significantly longer on A. craccivora and A. gossypii and shortest on C. lanigera. This study also provides authentic characters for sex determination of adults of M. igorotus.Keywords

Three species of Trichogramma, T. rabindrai, T. pieridis and T. giriensis have been described as new. The first species was reared from the eggs of a sphingid on a marshy weed bordering paddy fields at Someshwar and Saligrama in Udupi District, the second one from those of a pierid on Cassia fistula at Balehonnur, Chickamagalur District (both Karnataka) and the third from unidentified lepidopterous eggs on bamboo leaves at Tusharagiri (Kerala). The taxonomic significance of scutellar bristles, RS1 row of setae in the forewings and setal arrangement in the hind wings are discussed. A key to differentiate the three newly described species from other closely resembling ones has been included.Keywords

Two new species of Trichogrammatoidea, Trichogrammatoidea ruficolorata and T. brevicaudata are described from Bangalore, India. The males are morphologically similar to T. armigera and T. fulva, respectively. The relative lengths of ovipositor to hind tibia are markedly different in both pairs of species serving to differentiate between these species pairs. Females have therefore been designated as holotypes.Keywords

The woolly aphid, Ceratovacuua lanigera Zehntner (Homoptera:Aphididae), assumed an epidemic proportion in Maharashtra and Karnataka in the year 2002. Presently this pest is prevalent in India in major sugarcane growing areas and it is important to find out the population differences to assess their epidemic potential. Molecular markers such as internal transcribed spacer (ITS) play an important role to bring out the population differences at the molecular level. Hence, ITS 2 region of C. lanigera was sequenced using specific primers (product size 448 bp) and the sequence was submitted to GenBank (DQ 825651).Keywords

During the course of studies on the life histories of insects of the Andaman Islands we observed 38 species of hymenopterous parasitoids belonging to 15 families and one dipteran parasitoid of the family Tachinidae. Eight species of Hraconidae, four species each of Scelionidae, Encyrtidae, and Ichneumonidae, 3 species each of ('teromalidae, Eulophidae and Eupelmidae, 2 species of Bethylidae, one species each of Elasmidae, Eurytomidae, Chalcididae, Ceraphronidae, Chrysididae, Torymidae, Eucharatidae and Tacbillidae are recorded from these islands on different insect hosts. An undescribed Ooencyrtlls sp. is being recorded from the eggs of the endemic subspecies Elymnias cottonis cottonis. Podagrion sp., hitherto recorded from man tid oothecae, is recorded on the larvae of two species of Lepidoptera for the first time.Keywords
