The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period of November, 2016 to April, 2018 to observe the performance of different brinjal varieties under different pest exclusion net (PEN) covers against major insect pests of brinjal. A two factorial experiment was laid out in split plot design with three replications. Three varieties of brinjal, viz., Narsingdhi (V1), Singnath(V2) and Charki (V3) were grown under different PEN conditions, viz., Open field or control (T0), 20 mesh (T1) and 40 mesh (T2). Among varieties, maximum gross yield (58.8 t/ha), marketable yield (37.1 t/ha) were found in V1 (Narsingdhi) while the minimum in V2 (Singnath). In case of gross yield (58.8 t/ha) and marketable yield (37.1 t/ha) were found maximum under 40 mesh white PEN (T2) and minimum in open field (T0). Again, number of infested fruits (12.5), branch infestation (76.4%) and marketable yield reduction (30.4t/ha) were found maximum in T0 while minimum in T2 due to less infestation. In combined effect, the highest marketable yield (51.3t/ha) was obtained from V1T2 .So, it can be concluded that 40 mesh white pest exclusion net (T2) could be regarded for getting highest commercial brinjal yield in Bangladesh.
