Abstract
The present investigation was carried out at Awadlab village-Edfu district, Aswan Governorate during 2003& 2004 seasons to magnifying the role of parasitoid Coccophagus scutellaris ( Dalman )as element from ( IPM ) and evaluated seven insecticide from different groups for control the soft scale insect Pulvinaria tenuivalvata (Newsted) in sugarcane fields. The obtained results clearly showed that, percentage of parasitism significantly increased from 17.64% before release to 60.44% after release in the 1st season while in the 2nd season increased from 27.45% to 73.88%, also percentage of estimated parasitism recorded 32.62%& 37.87% in the 1st & 2nd seasons respectively. On the other hand in the 1st season the highest effect after15 days and 30 days in total individual (nymph & adult) observed in Actellic (95.77% & 98.21%) flowed by Malathio (91.47% & 95.63%) , Sulfur (89.01% & 94.37%) , Admiral(88.94% & 93.86%) (Malathion+ Sulfer) (87.86 % & 94.37 %) Agrieen (86.52 % & 92.11%) and Manf( 84.81 % & 89.59 %) respectively, while in the 2nd season the data showed that the highest effect after 15 days in total individual (nymph & adult) observed in Actellic which recorded 95.55% followed by Malathion, Sulfer, Admiral, Agrieen , ( Malathion + Sulfer ) and manf which recorded 91.33%, 87.96 % , 87.51 %, 86.17 %, 85.33% and 84.71% respectively. while after 30 days the highest one was Actellic which recorded 98.3% followed by Sulfer, Malathion, Agrieen, Admiral, (Malathion+ Sulfer) and manf which recorded 94.79 %, 94.71%, 94.61%, 94.36%, 93.44% and 92.2% respectively.
