| Abstract | ||
| The present investigation was carried out in Sohage Governorate, Egypt on sugarcane infested with Saccharicoccus sacchari (Cockerell) (Hemiptera: Pseudococcidae) during growing year 2007/2008. Obtained results indicated that only sever infestation significantly affected sugarcane physical and chemical properties. There were reduction of stalk's weight (5.03, 34.33%), stalk's height (2.16, 6.93%), stalk internodes' number per stalk (8.8, 29.07) and juice weight (2.26, 31.62%) in low and heavy Infestation, respectively compared with infestation free. Internodes height increased by 8.59 and 35.45% due to low and sever levels of infestation, respectively. There were losses of brix (4.95, 13.47%), sucrose (6.29, 27.87%), purity (1.41, 16.87%), pol (5.29, 32.6%) and sugar recovery (5.29, 37.08%) and increase of reducing sugar (3.53, 7.68%) and fiber (1.28, 3.85%) due low and heavy levels of infestation, respectively. | ||
