| dc.description.abstract | Mungbean is an ecologically important food grain legume crop. Susceptibility towards
different insect pest has limited the productivity of mungbean. A study were conducted
with six mungbean varieties viz. BARIMUG 4, BARIMUG 5, BARIMUG 6, BINAMUG
5, BINAMUG 6 and BINAMUG 8 on the tolarance of different insect pests during the
growing period (May to June, 2014). Aphid (Aphis craccivora Koch), jassid (Empoasca
kerri), thrips (Megalurothrips distalis), pod borer (Maruca testularis), bean bug
(Riptortus pedestris), epilachna beetle (Epilachna spp.) and hairy caterpillar (Diachrisia
obliqua) were identified as pests in all tested varieties. Thrips was a major and first insect
pest which showed highest incidence in different mungbean varieties to compare with
other insect pests. Aphids also showed second highest incidence in different varieties of
mungbean. Presence of different insect population (adult) in six mungbean varieties
xxvii
showed highest in 2nd and 3rd week of the month May and gradually were decreased
after 3rd week of this month. BARIMUG 4, BARIMUG 5, BARIMUG 6 and BINAMUG
5 were highly susceptible to thrips and aphids while, BINAMUG 6 and BINAMUG 8
were less-susceptible. BARIMUG 4, BARIMUG 5, BARIMUG 6, BINAMUG 5 and
BINAMUG 8 were the less-susceptible to hairy caterpillar, but only BINAMUG 6 was
the less susceptible to aphid, epilachna beetle and hairy caterpillar compare to the other
mungbean varieties. BINAMUG 5, BINAMUG 6 and BINAMUG 8 appeared to be the
varieties in terms of less susceptible and yield. Among the mungbean varieties the highest
yield (1.42kg) obtained from BINAMUG 5 while, it was the lowest (0.52 kg) in
BARIMUG 4. Therefore, BINAMUG 5, BINAMUG 6 and BINAMUG 8 appeared to be
the best varieties in terms of tolarance and yield. | en_US |
