University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    POPULATION DYNAMICS OF LEAF ROLLER, Diaphania pulverulentalis (HAMPSON) (LEPIDOPTERA: PYRALIDAE) OF MULBERRY AND ITS SENSITIVITY TO INSECTICIDES WITH VARIED MODES OF ACTION AND THEIR SAFETY TO SILKWORM, Bombyx mori L.

    The experiment was carried out in the Department of Sericulture, University of Agricultural Science, GKVK, and Bengaluru during 2016-2019. The survey on leaf roller indicated that, the incidence was peak during September 2018 (38.15 %) at Ramanagara and October 2017 (40.12 %) at Chintamani. The correlation studies revealed that, there was significantly negative influence of maximum temperature and significantly positive influence of relative humidity, rain fall and biotic factors on the abundance of leaf roller. The insecticide emamectin benzoate caused maximum pest reduction (83.00 %) after 9 days of spray under field condition, followed by chlorofenapyr (82.51 %), fipronil (82.34 %), azadirachtin (81.66 %), lambda-cyhalothrin (79.57 %), novaluron (78.46 %) and profenofos (77.37 %). The bioassay studies indicated that, lambda-cyhalothrin and emamectin benzoate highly toxic even after 30 days after spray (DAS). However, the rearing parameters recorded with chlorofenapyr @ 10 DAS, azadirachtin and novaluron at 25 DAS, profenofos and fipronil at 30 DAS which were on par with dichlorvos and untreated control. The findings of present study clearly indicated that the insecticide chlorofenapyr was safe to silkworms even at 10 DAS followed by azadirachtin and novaluron at 25 days after spraying and profenofos and fipronil at 30 days after spraying.

    UTILIZATION OF SILKWORM (Bombyx mori L.) PUPAL RESIDUE FOR BIOCONTROL AND VALUE ADDITION
    (University of Agricultural Sciences, Bengaluru, 2018-08-30) VISHAKA, G. V.; Narayanaswamy, T. K.
    The present study was undertaken to utilize silkworm pupae disposed by silk reeling units viz., Vijayapura, Sidlaghatta and Chintamani of Chikkaballapur district of Karnataka. Designed special equipment for extraction of silkworm pupal residue biosoft descent (SPRBD) from silkworm pupal residue collected from reeling units. Significantly higher quantity of 3.10 Kg (52 %) SPRBD was extracted at 18 tonnes pressure. Invitro evaluation of SPRBD exhibited that at 40 %, significantly highest inhibition of 100 % mycelial growth was documented for Alternaria solani followed by 90.00 % (Fusarium oxysporium). Evaluation of SPRBD against Alternaria solani under glass house conditions proved minimum disease severity at 45, 60, 75 and 90 days (6.70, 14.33, 28.93 and 43.10 %) in the tomato plants treated with SPRBD @ 10 % before and after incidence of disease (T6: SPRBD @ 10% spray before and after inoculation with Alternaria solani). The SPRBD as nutrient source on tomato yielded highest plant height (96.20 cm), number of branches per plant (28.67), number of flowers per plant (87.67), stem girth (2.17cm) recorded on 90 days after planting, respectively in T4 (SPRBD @ 4 % + T8- Recommended dose of fertilizer + FYM/ha/year). Significantly highest Shoot weight (173.10 g), root weight (10.17 g) and total biomass per plant (37.23 g) was yielded at harvest stage. The yield parameters like total number of fruits (50.17), fruit weight (50.50 g) and fruit yield per plant (4.27 kg) was exhibited highest in T4 (SPRBD @ 4 % + T8). The silkworm pupal Dark Chocolate (SPDC), silkworm Pupal White Chocolate (SPWC) and silkworm pupal tamarind ball (SPTB) with 5 per cent SPRP incorporated and for masala cookies 7 per cent was found to be best accepted with scores for appearance (8.0, 7.4,7.5 and 7.8), colour (8.1, 7.6, 7.6 and 7.6), texture (8.1, 7.4, 7.8 and8.0), aroma (8.0,7.4 ,7.8 and 7.4), taste (8.2,7.5 ,7.0 and7.6) and overall acceptability (8.2,7.4,7.7 and7.6).

    SENSITIVITY OF IMPROVED BREEDS AND HYBRIDS OF MULBERRY SILKWORM TO BmNPV AND MANAGEMENT PRACTICES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK, BANGALORE, 2007-06-06) K. HADIMANI, DURAGAPPA; DEVAIAH, M. C
    Sensitivity of four improved breed s (CSR2, CSRt, MH\, BL43) and five hybrids of mulberry silkworm (CSR2 x CSRt, CSR4 x CSR2, MH) x CSR2, BL43 X CSR2 and PM x CSR2) with two concentration (10-3 and 10-6 PIBs) ofBmNPV were tested under laboratory condi tion s. The ET50 for symptom ex pression and ET50 for mortality were min imum in CSR2 when inoculated with BmNPV, while the same were maximum in PM x CSR2. The ERR was significantly maximum in PM x CSR2 and it was minimum in CSR2 when treated with BmNPV. The cocoon traits (cocoon, pupal and shell weights) except shell ratio were found to be nonsignificant in improved breeds and hybrids of silkworm when inoculated with BmNPV. Among the improved breeds and hybrids of silkworm, the cocoon filament length and cocoon fila ment weight were significantly maximum in CSR2. The cocoon filament length and cocoon f lament weig ht were significantly minimum in MH) x CSR2• Among the concentrations of PIBs, ET50 for symptom expression was less but ETso for larval mortality was minimum at 10-3 PIBs Iml with reduced econonuc parameters. The consumption, digestion an.d consumption indices were significantly minimum among .BmNPV inoculated batches compared to non-inoculated ones, irrespective of breedsl hybrids and PIBs concentration both ~uring fourth and fifth instars. The total "protein, total carbohydrate and free amino acid contents of haemolymph, the digestive amylase activity, gut and haemolymph pH were greatly altered in BmNPV infected worms compared to untreated worms. The silkworms (CSR2 x CSRt) reared on mulberry leaves dipped in aqueous leaf extracts of Psoralea 'cory leifolia L. @ 800 ppm was found effective in reducing the larval mortality due to BmNPV (10-3 PIBs) infection besides enhancing the economic traits of silkworm.
