Insect pests infestation on some promising sugarcane clones under the natural conditions in Bangladesh



 

ABSTRACT: The experiments were conducted to observe the infestation of different insect pests on some promising sugarcane clones under natural condition. Considering different cropping seasons, the average lowest infestation was occurred by early shoot borer (1.33%) and the highest by rootstock borer (48.47%). The average infestation level of different insect pest on some promising sugarcane clones revealed that the lowest was by early shoot borer, black beetle, top shoot borer, stem borer (stalk), stem borer (internode), rootstock borer, mealy bug and scale insect in the clones I 212-11 (0.69%), I 198-11 (1.30%), I 106-11 (6.18%), I 106-11 (10.53%), I 131-10 (15.05%), I 106-11 (37.93%), I 103-10 (17.44%) and I 103-10 (2.36%), respectively. It was revealed that among the clones I 106-11 provided the best performance in respect of different major insect pest infestation, and this clone may be released as BSRI Akh 48 variety for commercial cultivation in sugarcane growing areas of Bangladesh.
