Abstract
The sugarcane (Saccharum officinarum) is a very important cultivated crop in many states of India. This crop is grown throughout the year; hence it is infested by a large number of pest (fungus, insects etc.). According to a study, sugarcane production is declined by 20-30% or more. Out of several insect pest, Scirpophaga nivella (Fabricius) is one of the notorious pest of this crop sugarcane. This pest infests sugarcane crop of three months old crop to till harvesting stages and some similar plants too. In integrated pest management (IPM) several suitable techniques or methods are used harmoniously with the least disruption of the ecosystem. Thus, IPM is being applied to control the top shoot borer (S. nivella). Seven different modules were tested to control the infestation of top borer. The percentage of incidence of S. nivella in module-4 (T. chilonis+ T. howardi + carbofaran) were 2.8, 2.2, 1.1 and 0.6 in II, III, IV and V broods respectively which were very less, with highest cane yield of 89.43 t/ha as compared to the other modules tested. From the present work, we would recommend for the use of carbofuran(pesticide), Trichogramma chilonis (Ishii), and Tetrastichus howardi (Olliff) for the higher sugarcane production of Variety Co 0238.
