University of Agricultural Sciences, Dharwad

The University of Agricultural Sciences, Dharwad was established on October 1, 1986. The University has 5 Colleges, 27 Research Stations, 6 Agriculture Extension Education Centers, 6 Krishi Vigyan Kendras and ATIC. The University has its jurisdiction over 7 districts namely Bagalkot, Belgaum, Bijapur, Dharwad, Gadag, Haveri, and Uttar Kannada in northern Karnataka. Greater diversity exists in soil types, climate, topography cropping and farming situations. The jurisdiction includes dry-farming to heavy rainfall and irrigated area. Important crops of the region include sorghum, cotton, rice, pulses, chilli, sugarcane, groundnut, sunflower, wheat, safflower etc. The region is also known for many horticultural crops. Considerable progress has been registered in the field of education, research and extension from this University.

    EVALUATION OF SEX PHEROMONE AND STICKY COLOUR TRAPS FOR MONITORING OF SHOOT AND FRUIT BORER (Leucinodes orbonalis Gueene.) IN BRINJAL
    (University of Agricultural Sciences Dharwad, 2015-06) ARAVINDA M.; Dr. S. S. UDIKERI
    Studies on evaluation of sex pheromone and sticky colour traps for monitoring of shoot and fruit borer (Leucinodes orbonalis Gueene.) BSFB in brinjal were carried out during 2013-14 at Jumanal and Hittanalli villages (Vijayapur Tq and District) under irrigated condition with Mahyco super 10 variety. Among the different pheromone traps evaluated for monitoring of BSFB, water trap proved to be most effective by attracting significantly higher number of moths throughout the season. The mean number of moths caught was 3.08 / trap leading to lowest shoot (5.48 %) and fruit (15.03 %) damage. The fruit yield in the plots having water trap (489 kg plot1) was also significantly higher amongst treatments. Can trap appeared to be next best treatment among other models used. Sleeve trap, delta trap and bottle trap models were ineffective as monitoring tool. Seven different sticky colour traps viz., Violet, Indigo, Blue, Green, Yellow, Orange and Red were evaluated for monitoring of BSFB. The moth attraction was nil to any traps except some stray attractions. There was no significant difference noticed in shoot damage, fruit damage and yield among these treatments. Thus the present study reveals no significance of colour traps with respect to Leucinodes orbonalis in brinjal.
