Effect of different synthetic chemical insecticides on potato aphid (Macrosiphum Euphorbiae, Thomas) and their inauspicious effects on lace wing in Skardu Baltistan, Pakistan

Abstract

The present investigation was carried out at Skardu Baltistan region during summer 2015 to find out the efficacy of different synthetic chemical insecticides on Potato aphid (M. euphorbiae) and their inauspicious effects on Lacewing in potato field. The field investigation were carried out with seven treatments with different level of Insecticide concentration, Movento ® (low) @ 80ml/100 lit water, Movento ® (medium) @ 100/100 lit water, Movento ® (high) @ 120ml/100 lit water, Difenthuron (low) @ 80ml/100ml lit water, Difenthuron (medium) @100ml/100 lit water, Difenthuron (high) @ 120ml/100 lit water. Results showed that Movento ® (high) was more toxic against potato aphid followed by Movento ® (medium) and Movento ® (low), respectively. While on other hand Difenthuron was found most lethal for the lace wing population followed by Difenthuron (high), Difenthuron (medium), and Difenthuron (low). The study recommends the use of Movento ®for the safe and effective control of potato aphid (M. euphorbiae). Farmers should use Movento ® for the control of Aphids (M. euphorbiae) in the field as it is the least toxic to lace wing population.
