| Abstract | ||||
| The present study was conducted at the experimental farm Nubariya Agricultural Research Station, West Nubariya and Damanhour (Hafs village), Al Behera Governorate during the two successive seasons, 2010/2011 and 2011/2012, to study the susceptibility of seven sugarbeet cultivars three multigerms and four monograms to infestation with tortoise, beetle Cassida vittata Vill, and their yield and quality characteristics. The seven sugarbeet cultivars (four monograms Helsinki, Ravel, MK2134 and Sible and three polyograms cultivars Oscar poly, Gazella and Lilly) used in this study. Besides the of the three pesticides (Radiant SC © 12%, Mospilan© 20% SP and Dursban© H 48% EC) for reducing population density of beetle. The population fluctuations of C.vittata (larvae and adults) numbers were increasing whenever plants became bigger. Combined analysis over seasons and location demonstrated that the Helsinki cultivar was more resistant to larvae and adults of C.vittata. But Sible cultivar was more sensitive to tortoise beetle C.vittata (51 larvae and adults /plants). The seven cultivars can be arranged cultivars ascending order at harvest crop, according to attract cultivars of tortoise beetle as follow: Helsinki, Mk 2134 , Gazella, Ravel, Lilly, Oscar poly, and Sibel (49.7, 49.8, 50.3, 50.8, 51.3 , 52.4 and 55.9), respectively. In addition, Helsinki cultivar was superior in most yield characteristics such as root, top, and sugar yields and of sucrose percentage. Radiant SC © 12% exceed when spraying and interact with seven sugarbeet cultivars in all the studied traits except T.S.S. percentage. Radiant SC © 12% was more toxic against tortoise beetle, Cassida vittata Vill (Larvae and Adults) in two regions through two seasons. | ||||
