- Abstract
Seasonal fluctuations of the population density of the sunt wax scale insect, Ceroplastes africanus Green (Homoptera: Coccidae) at Qena Governorate, Egypt and its parasitism were estimated on guava from May 2006 until April 2008. The parasitoid species, Anicetus africanus, Bothrriophrine tenuicornis, Microterys sp., Scutellista cyanea, Eublemma scitula and Marietta sp. were recovered from the scale insect. The sunt wax scale insect showed three annual peaks of abundance in the first year of study on June 20th; October, 20th and March 20th. In the second season of investigation, only two peaks were observed on July 20th and November 20th. Evaluations of mortality rates caused by the afore-mentioned parasitoids were estimated. Concerning the percentage of parasitism, the peaks were recorded on June 20th; August 5th; October 20th, 2006 and March 20th, 2007 in the first season. Throughout the second year, the same trend was followed as four peaks of parasitism occurred on July 5th; September 5th; November 5th, 2007 and March 5th, 2008.
