Abstract
The effect of Methoxyfenzoid, Indoxacarb and Emmamectin Benzoate on Carbohydrate and Phosphatase Enzymes of field collected Tuta Absoluta was investigated. Toxicity results against third instar larvae showed LC50 values was (50.77 ppm, 2.33 ppm and 0.22 ppm) for Methoxyfenzoid, Indoxacarb and Emmamectin Benzoate respectively. Additional results, indoxacarb and emmamectin benzoate are faster to kill than methoxyfenzoid where LT50 was (1420.8 min 1469.9 min and 2629.3 min) respectively. The biochemical results showed high increase in trehalase and acid phosphatase (17.93, 7.83%) respectively and slight increase in invertase and amylase activities (2.51 and 0.039%) respectively when treated with indoxacarb comparing the other two insecticide.
