Influence of plant resistance in certain genotypes of Blackgram on insecticide tolerance on Maruca vitrata (Geyer)
LPV Reddy and KV Hariprasad
Observations from field screening experiments revealed that blackgram genotypes, LBG-645, LBG-791 and LBG-790 showed resistant, moderately resistant and susceptible reaction to Maruca infestation. Further investigation on feeding preference of Maruca by free-choice and no-choice techniques on selected genotypes of blackgram in the laboratory to confirm the resistance ranking observed in the field screening, have yielded similar resistance reaction to Maruca infestation. Studies on topical bioassay with chlorpyriphos revealed that the larvae reared on resistant genotype of blackgram had lower LC50 and LD50 values as compared to larvae reared on susceptible genotype of blackgram.
