ABSTRACT: The study was undertaken during September 2020 to August 2021 in the experimental field and laboratory of the Department of Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur to know the abundance of sucking pests, particularly thrips and jassid on fifteen okra genotypes, and to assess their effects on fruit characteristics and yield of okra. The okra genotypes viz. BD 1851, BD 1854, BD 1860, BD 1861, BD 1863, BD 1892, BD 1897, BD 1900, BD 1904, BD 1907, BD 1911, BD 8615, BD 8617, BD 8618 and BD 8620 were used in experimental plots, and the abundance of the pests was observed from seedling to the harvesting stage of the fruits. The abundance of thrips and jassid varied among the genotypes. The lowest abundance of thrips and jassid were found on BD 1851 and BD 1892, respectively (11.0 ± 1.2 and 3.6 ± 0.4 adults/ 5 cm of top shoot). Genotype BD 8617 (2.8 ± 0.2 cm) showed the highest fruit diameter while BD 1892 had the longest fruit (15.6 ± 1.0 cm). BD 8617 and BD 8620 showed the highest fruit weight (31.6 ± 5.4 and 31.5 ± 3.5 g, respectively) which was statistically similar. Overall, BD 1892 showed better performance with the highest yield (3.2 t ha-1) and low abundance of both thrips and jassid than other genotypes.
