Periodic viڑits covered sugarcane plantations at Attfeih district (Gيa Governorate) during 2008 and 2009 seasons for surveying parasitoids of sugarcane soft sca/e, Pu/vinaria tenuivalvata. Data confirmed that the apheilnid parasitoid, Coccophagus scutellaris is the main parasitoid as ،t played a natural . active ro/e against this pest in nature. Results proved that a number of one to ten parasitoid adults emerged from a single host depending upon the age of the host. The second nymphal instar was the highest preferred for parasitism (96%), while the mature females were the lowest (57%) parasitism. The mean seasonal rate of parasitism was hi’her in 2009 (46. 35%) than 2008 (41.05%), thus indicating that C. scutellaris played oaturally an important role in reducing the population of the pest in sugarcane plantations at Attfeih district. Also, a field experiment was conducted atn Al-Rawda village (Mm/a Governorate) during the same seasons (2008 and 2009) in order to increase the proportion of parasitism in P. tenuivalvata infesting sugarcane plantations. Pa ras/ti ed soft scales were collected from heavily infested sugarcauie fields to be released in the area of experiment at a rate of 3 parasitized scales/p/ant. Re/easing led to increases in the number of parasitized soft scales and the percentage of parasitism by 170 and 117%, respectively ،n 2008 and 163. .1 and 139.8%, respectively in 2009 sugarcane season.
