Abstract

The seychelles fluted scale, Icerya seychellarum Westwood (Margarodidae: Homoptera) is a serious pest of mango in Egypt. As a basic study for developing future management of this scale species seasonal fluctuation of different stages and total population density within mango trees were monitored in a private mango orchards of mixed cultivars located in El-Sall, Giza Governorate, Egypt throughout two years started from January 2003 to December 2004. Seasonal fluctuation of total population on different mango cultivars was also studied. Under the climatic conditions of Giza Governorate, population of 1. seychellarum showed four annual generations and four activity peaks; a small peak in March, intermediate peak in June, and two large peaks in August and September/October. The overall population trends were similar among the two studied years. Population density showed significant positive correlation with temperature and insignificant negative correlation with relative humidity. Of the four studied mango cultivars the highest population density was recorded on the cultivar 'Sultanis followed by Baladi and Hendi while Ewaisi had the lowest annual population density during both 2003 and 2004 seasons. Differences in annual population density of 1 seychellatvm between the four mango cultivars were significant at 0.05 % level.
