Keywords:Amrasca biguttula, leafhopper, Confider, Neonicotinoids group
Cowpea leafhopper Amrasca biguttula is one of the important pests that afflict the cowpea crop in Iraq and cause economic losses. Therefore, chemical control was studied in the laboratory and its effectiveness in control was demonstrated, as a pesticide was used imidacloprid ;Confider of the Neonicotinoid schemical group Confider concentration was used for spray treatment 25ml/L,50,75,100ml/l. The concentration used for soil treatment is 100g/ml,200,300 ,400g/ml. The results were the treatment of the lowest hatching rate was obtained in leafhopper eggs for spray treatment when using a concentration of 100ml (reached 79.44%), observed that the average of mortality rate resulting from the use of a the pesticide Confider reached to (33.47%) , It is noted that the highest mortality rate was achieved after the passage of time 72 hours of treatment and reached (39.73%).
