A comparison of individual control methods and their combination into one model for management of sugarcane stem borer, Chilo infuscatellus Snellen, at Noor Wala 15-km Jampur road, D. G. Khan, Punjab, Pakistan. The methods in the form of treatments (T1 Trash mulching at the time of germination; T2 Collection of egg masses at 15days interval; T3 Removal of dead plant parts at 15days interval; T4 Furadan 3G Application @14kg Acre-1 (1st at germination and 2nd on earthing up; T5 Bio-control agent Trichogramma chilonis @ 30,000 parasitized eggs Acre-1 at 15 days interval from April to onward; T6 T1+T2+T3+T4+T5 (Treatments combination), T7 Control (No treatment) were organized in Randomized Complete Block Design, with three replications on two varieties (BF-162 and CP-43/33). Results showed that combination of methods provided 71.35% and 84.433% protection correspondingly against infestation and internode damage by C. infuscatellus. These protection resulted 369.98% and 44.58% increase in cane yield and sugar recovery respectively over control. The results are compared with earlier studies carried out elsewhere.
