| Abstract | ||||
| The present work was conducted in Kom Ombo district, Aswan governorate for two years (2002 & 2003) to evaluate the efficiency of seven compounds representing seven insecticidal groups for control the sugarcane soft scale, Pali/Iberia tenuivalvata (Newstead) in sugarcane fields to protect the crop from the insect damage. The obtained results showed that, the tested pesticides were highly effective on the insect populations in the both years (2002/2003). The statistical analysis of the evaluated pesticides combined over two tested years showed that, Chalinger was the highest effective compound on the nymphal populations (94.8%). Admiral and Mospilan came in the rd order (93.6% and 93.4%) followed by Marshal in the 3'0 order (88.9%). Suffer & Actara came in the 4th order (88.1% & 88%) and Orion was the last one (86.8%). The efficacy of the evaluated pesticides on the adult populations showed that, Chalinger, Admiral and Mospilan were the highest effective compounds on the adult populations (93.5%, 92.5% and 91 9%) followed by Marshal in the 2"' order (86.6%). Suffer, Actara and Orion were less effective pesticides on the adult populations (85.6%, 84.6% and 83.5%). The efficiency of the tested pesticides on the insect populations (nymphs and adults) indicate that, Chalinger was the highest effective compound (94.6%) on the insect populations followed by Admiral and Mospilan in the 21'd order (93.4% and 93.1%). Marshal and Sulfer came in the rti order (88.2% and 87.7%), Orion was the least one (86.6%). | ||||
