abstract
Madhya Pradesh is one of the main soybean producers in the country. But a considerable part of the production is lost due to Bemisia tabaci (Genn.) attacks. Resistant plants can be an important method for controlling this pest in an integrated pest management. Tests for evaluating some biological aspects of B. tabaci were carried out on three soybean cultivars, in controlled laboratory conditions (25± 2⁰ C, 70±10% RH, 13 photophase). Trifoliate plants placed in plastic cages were infested with a pair of whitefly, for 72 hrs. The development was observed until adult emergence. The development period of insects grown on JS-20-98 cultivar (23.0±3.0 days) took 4-7 days longer when compared to the grown in JS-97-52 (19.0±3.0 days) and JS-335 (16.5±2.5 days). Adult emergence percentage highest on JS- 335(92.30%), JS- 97-52 (85.19%) and JS-20-98(76.19%).The highest mortality rate of whitefly egg to whitefly occurred in JS-20-98(77.04%) and followed by JS-97-52 (38.48%) the lowest on JS-335 (24.89%, respectively). The length and width of the immature stages varied on JS-335, JS-97-52 and JS-20-98.
