Anatomical characteristics of brinjal shoot and fruit of 5 resistance/susceptible brinjal varieties/lines viz. BL 099, BARI brinjal-6, BL 117, BL 072 , BARI brinjal -1 and wild Solanum torvum was studied at the experimental farm and Entomology laboratory of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during the period from September 2004 to April 2005 in a randomized block design with three replications. From the observation it seem that resistant brinjal varieties (BL 099, BARI brinjal-6, BL 117, BL 072 , and wild Solanum torvum ) with thick cuticle, broad and thick collenchymataous area (8-9 layers), compact paranchyma cell, compact arrangement of vascular bundle and small pith area (1.67 mm) showed lower shoot infestation. Where as susceptible variety (BARI Brinjal-1) has thin cuticle and collenchymatous area (6-7 layers), loose pharanchyma cell, poorly develop vascular bundle and large pith area (3.47 mm). The thickness of pericarp and mesocarp were positively correlated (R2=0.64, 0.38) with the degree of fruit damage.The percent of fruit infestation decreases with the increases in number of seed per gram flesh of brinjal fruit. The variety having compact seed ring (BL009 and wild S.torvum with closely arranged seeds in mesocarp showed less infestation while variety with less compact seed ring with distantly arranged seed (BARI Brinjal-1) suffered more fruit infestation.
