HOST PREFERENCE OF DIFFERENT INSECT PESTS ON DIFFERENT VARIETIES OF MUNGBEAN

Abstract

To evaluate the varietal preference of mungbean against major insect pests, an experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh during March-June, 2015. The experiment consisted of seven mungbean varieties namely BARI Mung-3 (V1), BARI Mung-4 (V2), BARI Mung-6 (V3), BARI Mung-5 (V4), BINA Mung-5 (V5), BINA Mung-6 (V6) and BINA Mung-8 (V7), which were laid out in Randomized Block Design with three replications. The occurrence and incidence of, whitefly (Bemisia tabaci), aphid (Brevicoryne brassicae), bean thrips (Caliothrips fasciapus) and bean podborer (Maruca vitrata) were observed and recorded in the field of all mungbean varieties. Among seven mungbean varieties BARI Mung-3 (V1) was found to be the most susceptible host for bean podborer, whitefly, aphid and bean thrips. Conversely, the BARI Mung-6 (V4) was found to be the least preferred host against most of the insect pests. Considering the yield potential, BARI Mung-6 (V4) produced the highest yield (1148.89 kg/ha), and the BARI Mung-3 (V1) produced the lowest yield (857.22 kg/ha).
