SPECIES RICHNESS AND HOST DIVERSITY OF SYRPHID FLIES (SYRPHIDAE : DIPTERA) OF JAMMU AND KASHMIR STATE ( INDIA)
The present communication incorporates an updated checklist of syrphid flies of Jammu and Kashmir region, including 41 species, belonging to 21 genera, with their host aphid/plant species and distributional range. The host plant- range of 11 species of aphidivorous syrphid species, has been elaborated, suppressing populations of 38 aphid species, damaging 36-host plant species. Data on host-plant diversity of 24 species of adult syrphids, attracted to the flowers of 47 plant species, under 30 genera, has also been provided
Diversity of butterflies (Lepidoptera: Papilionoidea and Hesperoidea) of Dachigam National Park, Jammu and Kashmir, India
This preliminary study documented the diversity of butterflies of Dachigam National Park from 2004 to 2007.The field investigation was confined mostly to lower areas of the National Park and 27 species of butterflies were recorded. Except Hesperiidae, all the families were mostly active from April to August. 18 species showed mud puddling behaviour. Junonia orithya (Linnaeus) (Blue Pansy) and Neptis sappho Pallas (Pallas’ Sailer) are reported for the first time from Kashmir Valley
Studies on thrips (Insecta: Thysanoptera).
The present study encompasses results of the original research on thrips belonging to order thysanoptera (insect). It comprises of several chapters, divided into 5 sections. The theses include general introduction, review of literature, materials and methods and morphological features. It deals with systematics of Thysanoptera of Kashmir valley and embodies thrips-trapping studies (bioecology).It studies the thrips pests damaging agricultural and horticultural crops of Kashmir. The thesis contain 61 figures, plates , five tables and one detailed map of Kashmir Valley indicating various areas- Localities surveyed

The present investigation was undertaken for characterizing wild jamun genotypes using DNA marker technology. Twenty three genotypes of wild Jamun comprising of twenty one from Andaman and Nicobar Islands and two from mainland were selected for analysis. A set of 30 ISSR and 20 RAPD primers were taken for DNA fingerprinting, among them 17 ISSR and 19 RAPD primers produced 70 and 126 amplicons out of which 43 and 70 amplicons were polymorphic having 61.4 and 55.5% polymorphism, respectively. The maximum discriminating band was obtained from primer ISSR8 and OPA7. Cluster analysis divided the all genotypes into five clusters with both RAPD and ISSR markers. The present study has not only differentiated islands genotypes from mainland but even clustered genotypes separately. The genotype collected from Car Nicobar was distinct with both RAPD and ISSR markers.Not Availabl

Not AvailableTwelve isolates of Trichoderma from Andaman and Nicobar Islands have been evaluated for their biocontrol potential under in vitro and field conditions during 2008–09, 2009–10 and 2010–11 against Fusarium oxysporum f. sp. lycopersici causing wilt of tomato. The isolates Th-CARI-50, Tv-CARI-73, Tv-CARI-85 and Th-CARI-61 were most efficient in the hyperparasitic action on the test pathogen in dual culture test. The biopriming of seeds with Trichoderma isolates and bacterial antagonist significantly improved the germination behaviour of tomato seeds as compared to control. Mycelial form of inocula was proved better than conidial inocula of Trichoderma in inducing germination (%) of tomato seeds. The isolates Th-CARI-61 was proved most effective in inducing per cent germination (90% -mycelial inoculums; 88% -conidial inocula), seedling vigour (945 – MI; 889 -CI), seedling biomass (395.5 mg - MI; 355.4 mg - CI) of tomato seedlings followed by Tv-CARI-85, Th-CARI-50, Tv-CARI-73, P. fluorescens, Tv-CARI-110, Th-CARI-72, whereas Th-CARI-130 was noted with least effective. The seed and soil application of Trichoderma spp. was most effective in reduction of disease incidence of fusarial wilt of tomato under both greenhouse and field conditions than that of either seed or soil application alone. Th-CARI 50 was most effective in inducing germination (92%), lowest disease (16.4%) and highest reduction of disease incidence (80%) followed by Th-CARI-61, Tv-CARI-85, Tv-CARI-73, Th-CARI-130 and the isolate Tv-CARI-100 was least effective (54.9% RDI). T6 treatment (Th-CARI-50) was most effective in improving field emergence (90.2%) of tomato seedlings, reduction in fusarial wilt disease incidence (78.8%) and corresponding yield increase (138%) of tomato under field condition followed by T12 (Tv-CARI-73), T15 (Tv-CARI-85) and T3 (Th-CARI-61).Not Availabl
