Description The present studies were carried out during the year 2005 in
Pulses Section, CCS Haryana Agricultural University, Hisar. Eighteen
genotypes of mungbean were evaluated to study the population
dynamics of whitefly and infection of mungbean yellow mosaic virus on
different genotypes. Out of 18 genotypes, MH 412 and MH 435
genotypes harboured the minimum population of whitefly adults, eggs,
nymphs and pupae whereas, MH 420 and K-851 for whitefly. Genotype
MH 435 was found resistant mungbean yellow mosaic virus whereas,
MH 401 was highly susceptible and K-851 were the most preferred
hosts for whitefly. Genotype MH 435 was found resistant to mungbean
yellow mosaic virus whereas, MH 401 was highly susceptible and K-851
susceptible to MYMV infection.
Meteorological parameters were also correlated with the
population of whitefly. Temperature, pan evaporation, sunshine showed
positive and non-significant correlation while relative humidity and
rainfall were negative and non-significantly correlated with population

whitefly. Phenotypic characteristics of 18 different genotypes of
mungbean were studied, to evaluate their correlation with incidence of
B. tabaci. Phenotypic characters such as leaf size and glabracity
showed positive and significant while leaf thickness was negative and
significant correlation with whitefly population. There was no
correlation between length of setae with whitefly population.
Two insecticides imidacloprid 200SL and dimethoate 30EC were
used for seed treatment and four namely imidaclopird 200SL,
oxydemeton methyl 25EC, NSKE and Verticillium lacani including
combination with the seed treatments were applied against B. tabaci in
field conditions. Seed treatment with imidacloprid 200SL @ 3ml and
dimethoate 30EC @ 5ml/kg seed followed with spraying of NSKE 5%
proved most effective treatments in controlling whitefly and mungbean
yellow mosaic virus on mungbean. Seed treatment with imidacloprid
200SL @ 3ml and dimethoate 30EC @ 5ml/kg seed proved better than
untreated control in realizing yield. Seed treatment with dimethoate
30EC @ 5ml/kg seed showed maximum cost benefit ratio.
