An experiment was conducted at BARI Central Farm, Gazipur during 2013 to screen 10 exotic chilli gerplasms against thrips and mite. The germplasm AVPP 1212 recorded significantly the lowest population of thrips/twig (2.00) followed by PBC 145 (2.42) and AVPP 1236 (2.75). Similarly, the lowest population of mite (0.74 /five leaves) was noticed in AVPP 1212 which was followed by PBC 145 (1.00) and AVPP 1236 (2.52). So, three chilli germplasms viz. AVPP1212, PBC 145 and AVPP 1236 were found promising in view of least thrips and mite population. Rest of the germplasms recorded much higher population of both thrips and mite than the check variety BARI Morich 1.

Pest Management
To screen 10 exotic chilli gerplasms against thrips and mite.
Ten chili genotypes received from AVRDC (The world vegetable centre), Taiwan and a commercial variety BARI Morich 1 (used as check) were planted at BARI Central Farm, Gazipur during February 2013. The experiment was laid out in RCBD with 3 replications. The unit plot size was of 2.5 x 2 sq-m. The recommended agronomic practices were followed to raise the crop. No insecticide was applied during the entire cropping season. To study mite population five plants were selected randomly from each plot and tagged. The plants were again untagged after recording the mite population to avoid observation from the same plant. Six leaves from each plant (two each from bottom, middle and top canopy) were plucked and kept in properly labeled polypropylene bag. Later, these selected leaves were examined under stereo-binocular microscope for counting the number of mites per leaf. To study thrips population another five plants were selected randomly from each plot. A sticky paper was placed under the selected plant and each twig was shaken gently, and thrips that fall on the sticky paper were noted down. Observations were recorded at seven days interval starting from 14 days after transplanting (DAT) upto last harvesting of fruits.

Among 10 exotic chili gerplasms AVPP 1212 recorded significantly the lowest population of thrips/twig (2.00) followed by PBC 145 (2.42) and AVPP 1236 (2.75). Similarly, the lowest population of mite (0.74 /five leaves) was noticed in AVPP 1212 which was followed by PBC 145 (1.00) and AVPP 1236 (2.52). So, three chilli germplasms viz. AVPP1212, PBC 145 and AVPP 1236 were found promising in view of least thrips and mite population.
