| Abstract | ||||
| The life stages of Bemisia species complex were surveyed on thirty plant hosts belonging to thirteen botanical families in Dakahlia Governorate, Egypt, to estimate the degree of pest colonization on each host during 1997 & 1998. Among these families are Solanaceae, Euphorbiaceae, Curciferae, Cucurbitaceae, Leguminaceae, Malvaceae, which were the most preferable for the reproductive process of Bemisia spp. Meanwhile, other plant families showed a little colonization degrees of its life stages. However, cabbage, squash, cotton, tomato, caster bean, cauliflower, labannet el-homara weed and potato harbored the highest populations of the insect. The other hosts established moderate or small colonies of Bemisia spp. in both years. The effect of growing seasons on the degree of Bemisia spp. colonization was discussed. Summer and perennial plant-hosts were apparently favored by Bemisia spp. for reproduction during the warmer weather. Meanwhile, winter host plants were as significant overwintering sites. Generally, the degrees of the insect population densities differed according to plant species and leaf age of the same plant. The correlation coefficient parameters between Bemisia spp. life stages were highly significant and positive. | ||||
