Abstract |
Laboratory experiments were conducted to determine the efficiency of different pesticides belonging to various biological and synthetic chemical groups against 2"d instar larvae of cotton leafworm S.littoralis ( Boisd) and Aphis gossypii (Glover).
Results revealed that LCso and toxicity index of the tested compounds against 2"d instar larvae of cotton leafworm were (1.54,4.17 and 10.55 ppm) and ( 100, 36.88 and 14.56 % ) for Betacyfolathrin, Fenpropethon and Es-Fenvolerate, respectively. Although for the Bio-compounds, Spinosad and Abamactin the obtained values of the two tested compounds were 21.40 and 150.88 ppm ) and (100and 14.18 % ) respectively.
In case of Aphids pest values of LC50 and toxicity index were ( 0.015, 0.026, 0.042, 0.171, 0.29 and 0.503 ppm) and ( 100, 57.69, 35.71, 8.77, 5.17 and 2.98 %), for Beta-Cyoflathrin, Es-Fenvolerat, Chloropyrifos, Profenfos, Fenpropathrin, and Methomyl, respectively, while it were (17.512, 68.522 and 0.156 ppm ) and (100, 0.89, and 0.23) for Beauvaria basciana,Abamectin and Spinosad biocides, respectively. Co-toxicity factors of the binary mixture of ( Beta-Cyfoluthrin + Abamectin ) and ( Beta- Cyfoluthrin + Spinosad) at LC25 levels against 2"° instar larvae of cotton leafworn and A.gossypii were ( - 28.57 and - 100 ) and ( - 37.14 and - 72.97 ) respectively.
