There was a total five treatments including a check. Four insecticides including Oshin (Dinotefuron), Movento (Spirotetramate), Pyriproxyfen (Pyriproxyfen) and Matoi (Pyrifluquinazon) were used at the dose of 100 g, 125 ml, 500 ml and 200 g per acre respectively. The randomized complete block design was followed with three replications of each treatment. Insecticides were sprayed when the pest had reached the economic threshold level and data were recorded after three, seven, fourteen, twenty one and twenty seven days after treatment for comparison with pre-treatment pest population data. Results revealed that Matoi (Pyrifluquinazon) was the most effective insecticide against sugarcane whitefly in ratoon US-633 sugarcane variety with highest corrected mortality of 84.4 % followed by the Movento (Spirotetramate) with about 80% corrected mortality. The minimum corrected mortality (64 %) was resulted after spray of Oshin (Dinotefuron). It is concluded that Matoi (Pyrifluquinazon) should be recommended for control of sugarcane whitefly ata dose of 200 g/acre.

INTRODUCTION Sugarcane is an important gramineous crop with perennial growth pattern into tall sticks. Sugarcane crop is mainly utilized in the sugar industry and some other industries like paper, molasses, bio-diesel and its byproducts are used as fuel in bricks kilns, domestic fueling and small industrial fueling (James and Tate, 2004; Koohzad et al., 2017). This crop is providing major industrial raw material in sugarcane industry (Sadeghzadeh et al., 2011). Sugarcane crop is grown on large areas and its production is divided into many mill zones of Punjab, Pakistan. District Muzaffargarh has three working sugarcane mills, therefore, it is grown as monoculture crop in irrigated areas of Muzaffargarh. Due to monoculture cropping pattern of sugarcane in Muzaffargarh, many insect pests have developed on sugarcane crop including Aleurolobus barodensis (Maskell) and Neomaskellia andropogonis (Corbett), the two different species of whitefly. In Pakistan, mostly reported whitefly on sugarcane was Aleurolobus barodensis (Maskell). A. barodensis) is very serious and economical pest of sugarcane in Pakistan as well as Iran
