Diversity of insect pest, natural enemies and other beneficials arthropods community in selected Brinjal varieties/lines

Abstract :

Five brinjal varieties viz., BL099, BARI brinjal-6,BL117,BL072 BARI brinjal-1 were grown in replicated trial laidout in randomized block design at experimental farm and Entomology laboratory of BSMRAU for the measurement of diversity and equitability of arthropod community during 2005. The finding indicated that lower abundance of insect family in resistance variety/lines while a higher number of families are available in susceptible variety/line. All the resistant varieties showed higher equitability compare to that of susceptible one. A positive relationship was evident between the number of fswmilies and diversity index at all the crop growth stages (r=0.77 ). A negative relationship was observed between the number of families and equitability at all crop stages. (r= 0.31).
