The jassid (Amrasca biguttula biguttula (Ishida) is an emerging serious pest of brinjal crop in Pakistan. The present study
was carried out for evaluating relative plant resistance/susceptibility of different cultivars of brinjal against the jassid during
summer 2009 at PARS, Faisalabad, Pakistan. Fourteen cultivars of brinjal viz. Pusa Purple Round (PPR), Rubi, Vrib-01,
Vrib-02-F1, Dilnasheen, Vrib-0401, Vrib-04, Bemissal, Vrib-9901, Nirala, Qaisar, JK_Kajal, Cluster King and Purple QL
were tested for their susceptibility against jassid. All the tested cultivars showed significant differences (P≤0.05) for the
tested parameters viz. pest preference, host plant susceptibility indices (HPSI) as well as yield/plot. The peak infestation time
of the pest after sowing of crop was 1st week of June after which it gradually declined. The cultivars Nirala, Bemissal and
Vrib-04 appeared as comparatively susceptible showing high population of jassid/leaf while Vrib-9901, Vrib-0401, and Vrib02-F1 appeared as intermediate and Rubi, Vrib-01 and Cluster King were observed comparatively as resistant ones with least
number of jassid/leaf. The cultivar Bemissal proved the most susceptible varietyamong the tested ones showing maximum
level of HPSI (18%) and minimum fruit yield (44.66 kg/plot) while Rubi proved the most resistant cultivar with minimum
HPSI (7%) and a maximum fruit yield (81.0 kg/plot).
