Abstract: 

The efficacy of some new insecticides in comparison with two organophosphates, phosalone, and azinphosmethyl, were studied against codling moth Cydia pomonella L. in Orumiyeh apple orchards during 2003-2004. The experimental design was randomized a complet block with 4 replicates and 10 treatments as: acetamiprid (Mospilan SP 20) at the rate of 500 ppm, indoxacarb (Avaunt SC 150) at 300 and 450 ppm, lufenuron (Mach EC 50) at 1000 ppm, hexaflumuron (Consult EC 10) at 750 ppm, phosalone (Zolone EC 35) at 1500 ppm, fenpropatrin (Danitol FL 10) at 1000 ppm, thiacloprid (Calypso SE 480) at 300 ppm, azinphosmethyl (Gusathion EC 20) at 2000 ppm and check (water). Each plot consisted of three apple trees. The percent of efficacy was calculated based on the total infected and uninfected fruits for each plot. Results show that the differences of experimental treatments are significant at 1% level. Comparing the means revealed that there was a significant difference between all insecticides and check at 5% level, so all insecticides were effective against codling moth in comparison with the check. The efficacy of thiacloprid at 300 ppm, fenpropatrin at 1000 ppm and acetamiprid at 500 ppm was similar to azinphosmethyl at 2000 ppm, and their differences were not significant at 5% level. The hexaflumuron at 750 ppm and two 300 and 450 ppm doses of indoxacarb were in a separate group and because there was a significant differece at 5% level between this group and two standard insecticdes, azinphosmethyl and phosalone, then these compounds were not as effective as above mentioned organophosphates against codling moth.
