| Abstract | ||
| The prasent study showed that the Cyanophllum scale Abgrallaspis cyanophylli (Signoret) attacked both upper and lower leaf surfaces of the Night Blooming Jessamine Cestrum nocturnum L. (Solanaceae). The infestation concentrated on the lower leaf surface particularly the region around the mid – rib and the secondary veins. The percentage of infestation was 66.6 % - 100 % on plants and 42% - 95% on leaves during November 2004 in different nurseries and gardens at Baghdad . The study showed that the scale insect have many host plants. It attacked the Mulberry M. alba (Moraceae), Sago Palm C. revoluta (Cycadaceae), English Ivy H. hilex (Areliceae), Goose Foot C. album (Chemopodiaceae) and Alternanthera Alternathera spp . The study also showed that this insect can be reared successfully on potato tubers in order to get a good stock culture. Aphytis sp. was recorded on this insect, attacking the female stage. The female of this insect is oviparous laying the eggs under the wax scale. The average life cycle of both sexes female and male was 42.75 and 58.17 days respectively ,and the female has no parthenogenesis broods. | ||
