Sustainable management of Chilo infuscatellus (Pyralidae, Lepidoptera) by using non-chemical approaches
Abstract
Chilo infuscatellus (Pyralidae: Lepidopetra) is key pest of sugarcane crop that causes severe damage to cane and reduce the sugarcane recovery. Of several management practices that have been evaluated against C. infuscatellus, application of synthetic chemicals was considered the most important control method. During the past decade, chemicals remnants are prevailing in all compartments of agro-ecosystem, decreasing flora and fauna biodiversity. To replace these chemicals, non-chemical approaches are gaining momentum now a days. In present research, cultural and mechanical methods have been adopted to minimize the infestation of the pest. The results revealed that minimum infestation (12.91%) was recorded in treatment T1 (rash mulching) which significantly different from other treatments. The treatment T2 (Light traps) showed (14.09%) infestation which was statically at par with those of T3 (Propping), T4 (Hand collection of egg masses) and T5 (Detrashing) with increase of infestation (15.69%), (16.00 %) and (16.84%), respectively. The maximum infestation (25.71%) was recorded in T6 (control). The infestation was maximum (17.08%) after 20 day intervals while it was minimum (16.84%) after 10 day intervals. It was concluded that trash mulching is the best approach while infestation decreases when we put the application after ten days.
