| Abstract | ||
| Host preference of I.seychellarum (Westwood) (Homoptera, Margarodidae) on five mango cultivars showed that the highest mean number of insects in two studied years (2005 & 2006) was 16.7 individuals/ leaf occurred on Baladi cultivar, while the lowest mean number 0.0 individuals/ leaf occurred on Alphonso cultivar. The host plants could be arranged descendingly according to their preference by the insects in both studied years as follows: Baladi (16.7 individuals / leaf), Hendi (10.1 individuals/leaf), Ewasi (6.7 individuals / leaf), Timour (3.2 individual leaf) and Alphonso (0.0 individuals/ leaf). The egg production varied on different host plants with the maximum records on Baladi cultivar (37.6 eggs/ female) and the minimum on Timour cultivar (19.8 eggs/ female). | ||
