Abundance, distribution and population dynamics of Bemisia tabaci on brinjal and tomato

Abstract

In order to study the abundance, distribution and population dynamics of whiteflies (Bemisia tabaci Genn) in the agriculture farm and homestead garden of Patuakhali Science and Technology University (PSTU) campus and farmer’s field, brinjal and tomato plants were selected as study materials. Results revealed that the highest number of whitefly/plant (3.43) was recorded in brinjal at farmer’s field followed by PSTU farm (1.13) while lowest was in homestaed gardem (1.00) than tomato. The highest percentage of plant attacked per plot by whitefly was recorded in brinjal (16.67%/plot) while the lowest percentage was in tomato (9.76%/plot). The highest mean percentage of B. tabaci adult was observed in the middle canopy (64%) while the lowest was in lower canopy. The highest percent plant attacked (56.25%/plot) was recorded on 2nd March while the lowest attacked (9.09%/plot) was recorded on 15th February. The similar trend was also found in case of tomato. The highest percent plant attacked (56.25%/plot) was recorded on 2nd March followed by 1st April (50%/plot) and 17 March (33.33%/plot) while the lowest attacked (9.09%/plot) was recorded on 15th February followed by 30th January (10.98%/plot).Jahangirnagar University J.
