Redescription of the red-striped soft scale, (Newstead), with a new synonymy (Hemiptera, Coccomorpha, Coccidae).

The soft scale, (Newstead, 1911), is a major pest of sugarcane in Egypt. This paper provides a redescription and illustration of the adult female based on a microscopic study of the morphology of several adult female specimens and of the type series illustrated by De Lotto (1965) on citronella grass from Uganda. Two paratypes of De Lotto, 1964 are also studied and the name is placed here as a junior synonym of .

Efficacy of some oils and chemical compounds on Insignorthezia insignis (Browne) (Hemiptera: Ortheziidae) infesting Lantana camara in Alexandria, Egypt.

Field and laboratory experiments were conducted in March, 2008 in El-Nouzha garden, Alexandria governorate. Pre-and post treatment inspections of the insects were examined and recorded before and after (2,4,8, and 12 weeks). Spraying was applied to evaluate the efficiency of the tested compounds, [Mineral oils (KZ oil and Star oil); IGRs (Chlorfluazuron, lufenuron and pyriproxyfen); Neem oil; emamectin benzoate and thiamethoxam].

Comparative analysis of three scale insect species populations (Hemiptera: Coccoidea: Diaspididae) and their parasitoid, Aphytis diaspidis(Howard) on pear trees in Burg el-Arab area, Alexandria, Egypt.

The infestation abundance of each of the inspected scale insect species: San Jose scale, Diaspidiotus perniciosus (Comstock), Greedy scale, Hemiberlisio rapax (Comstock) and Olive scale, Parlatoria oleae (Cloveé) on pear trees, more or less varied as the months of each growing season differed. The comparative abundance percentages in both seasons of 2004-2005 and 2005-2006 were (51.80 and 51.
