| A major outbreak of the sugar cane soft scale Pulvinaria iceryi, an occasional pest of sugar cane in Mauritius, occurred in 1976/1977 when approximately 4000 ha were affected. In subsequent years, although present in sugar cane fields, it never reached damaging proportions. However, localised infestations have been recurring since 1997 and in 2001 and 2002 about 150 ha were severely infested. The effect of P. iceryi on mature sugar cane was assessed in six fields. Cane samples with slight, moderate and severe damage were taken from infested fields and compared with uninfested canes for brix, pol percent cane, juice purity and fibre percent cane. Cane height and number of internodes were also recorded. There was no significant difference in cane height and number of internodes. Moderate or severe infestations by P. iceryi significantly reduced brix, pol. percent cane and juice purity. Fibre percent cane was not affected. Reduction in IRSC ranged between 18 and 69 percent. These results illustrate the damaging nature of this pest, which needs to be constantly monitored in sugar cane fields. | |
