چکیده مقاله :
Diamondback moth, Piute/la xylostella L. is a major pest of Cruciferous crops worldwide. It out broke in cabbage fields of Tehran province in 1999 and caused considerable yield losses. Seven treatments including Biological and Chemical pesticides were used in the field test. These treatments were as follow: Consult (EC I 0%) 0.4 kg/h & 0.5 kg/h, Carbaryle (Wet able powder 85%) 2.5 kg/h, BtH (Iranian product as powder) I kg/h & 2 kg/h, Dipel~ (Wet able powder) 3 kg/h and the control in two factors randomized complete block design with split plot combined over times in four replicates. The results revealed that Consult 0.4 kg/h, Consult 0.5 kg/h, Carbarylc 2.5 kg/h and Oipct® 3 kg/h caused 79.09, 70.06, 70.01 and 65.77 percent larvae mortality respectively and were placed in one class of Duncan's Multiple Range Test. Btll I and 2 kg/h had less effect on this pest, and was placed in another class. Dipel was also more effective than BtI-1 on Diamondback moth larvae in laboratory bioassays.
