Abstract
Laboratory expennients were conducted to determine the efficiency of
different pesticides belonging to various biological and synthetic chemical groups
against 2d instar larvae of cotton leefworm Si?tor&is ( Boisd) and Aphis gossypii
(Glover).
Results revealed that LC50 and toxicity index of the tested compounds
against 2d instar taivae of cotton leafworrn were (1.544.17 and 10.55 ppm) and (
100, 36.88 and 14.56 % ) for Betacyfolathrin, Fenpropethon and EsFenvolerate,
respectively. Although for the Bío-cornpounds, Spinosad and Abamactin the obtained
values of the two tested compounds were 21.40 and 150.88 ppm )and(lOCand 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 (1001 57.69, 35.71, 877, 5.17 and 2.98 %),
for Beta-Cyofiathrin, Es-Fenvolerat, Chioropyrilos, Profenfos, Fenpropathrin, and
Methomyl, respectively, while ¡t were (17.51 2, 68.522 and 0.156 ppm ) and (100, 0.89,
and 0.23) for Beeuvena basaana ,Abamectin and Spinosad biocides, respectively.
Co-toxicity factors of the binary mixture of ( Beta-Cfoluthnn + Abamectin)
and ( Beta- Cyfoluthrin • Spinosad) at LCs levels against 2 instar larvae of cotton
iealworn and A.gossypì were ( - 28.57 and 100 ) and ( - 3714 and 72.97 )
respectively.
