EFFECT OF ABIOTIC FACTORS ON THE INCIDENCE OF MAJOR INSECT PESTS OF BLACKGRAM [Vigna mungo L. HEPPER]
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 17
Abstract
Field experiments were conducted during Kharif season of 2013 and 2014. The pest population was recorded in blackgram field, aphids, jassid, whitefly, thrips and blister beetle and aphid population attained peak in the 1st week of September during 2013 and 2nd week of September during 2014; the jassids and white fly remained active throughout the growing stage and attained the peak in the 4th week of August and last week of August during both years; thrips infestation reached its peak in the last week of August; the blister beetle population reached its peak in the 1st week of September in 2013 and last week of August in 2014. The infestation of pods was maximum in the 2nd week of September during both the years. The mean density and relative density values were the maximum for aphid during 2013 and 2014. Abiotic factors like temperature, relative humidity, extent and distribution of rainfall, influenced the infestation and stabilization of various insect pests in blackgram.
