“…A. lepidosaphes was the most common parasitoid on L. beckii (Abdel-Fattah andEl-Saadany, 1978 andHafez et al, 1987a). During the present work no occurrence of parasitism was noticed during January, February and March.…”

The purple scale, Lepidosaphes beckii (Newman) (Hemiptera: Diaspididae) is one of the most important pests attacking mango. The present paper includes population dynamics of the purple scale, L. beckii and its parasitoid. Dynamics of L. beckii and its parasitoid on mango trees was carried out in Giza, governorate, during 2009 and 2010. Only one parasitoid recorded in this work was Aphytis lepidosaphes Compere (Hymenoptera: Aphelinidae). Statistical analysis of the effect of weather factors on the population of L. beckii and its parasitoid during the two years under consideration was explained. The results indicated that maximum and minimum temperatures was significant on the population of L. beckii and its parasitoid, A. lepidosaphes while percent of relative humidity it is nonsignificant. As well as obtained results over both years indicated the occurrence of three generations per year for L. beckii on mango in Giza.

“…The highest total percentage of parasitism (30%) induced by T. ceroplastae was recorded during November 1993. HAFEZ et al (1987) reported that T. ceroplastae was the most abundant parasite of C. floridensis on citrus trees in Alexandria, Egypt, with the highest percentage in January and December and two recognizable peaks occurring in wiflter and summer. However, the present results assured the important role of T. ceroplastae as an effective parasite against the populations of C. rusci at the Mansoura district of Egypt.…”

“…The wax scale insects of the genus Ceroplastes (Hom., Coccidae) are widely distributed throughout the world and considered among the most injurious pests of fruit trees. Infestations with these insects are often associated with some hymenopterous parasites, which are major elements in their biological control (HAFEZ et al, 1987). The ectoparasite Scutellista cyanea Motsch.…”

Studies on the relationship between the population fluctuations of the wax scale, C. rusci L., and its parasites on quince trees were carried out in the Mansoura district for a whole year starting April, 1993 until March, 1994. Two annual generations of C. rusci were recorded, the summer one from April to September and the winter one from September to the next April. The two hymenopterous parasites, C. cyanea Motsch. (Pteromalidae) and Tetrastichus ceroplastae (Gir.) (Eulophidae) emerged from C. rusci. The highest monthly percentages of parasitism with S. cyunea (15.6%) and T. ceroplastae (30%) were recorded in September and November, respectively. The rate of parasitism induced by the two parasites together reached its peak (33.4%) in September. The results assured the important role of these parasites as biotic mortality factors against the populations of C. rusci in Egypt. 295-296.

“…The presence of A. lepidosaphes and Encarsia citrina were reported by other authors in Greece (Argyriou et al ., ; Katsoyannos, ). The parasitoid A. lepidosaphes is considered one of the most important biocontrol agents for the purple scale in other regions of the world (Dean, ; Abdel‐Fattah & El‐Saadany, ; Hafez et al ., ,b).…”

Data on ecology of the purple scale Lepidosaphes beckii (Newman) on citrus in Greece

The ecology of the purple scale Lepidosaphes beckii (Newman) (Hemiptera: Diaspididae) was studied on citrus, in the area of Kalamata (Messinia ‐ Peloponnese) from May 2009 to May 2011. Observations on infested citrus branches were conducted to study the phenology of the scale. Yellow sticky traps were hung in infested trees and examined to monitor the flights of male L. beckii as well as the flights of adults of parasitoids and predators of this pest. Lepidosaphes beckii mainly infested the leaves and fruits and to a lesser extent the shoots and stems. During the period of the study all developmental stages of L. beckii were found. Sticky transparent band traps were also placed on shoots and were examined to monitor the fluctuation in the population of crawlers. From the crawlers caught in the traps three population peaks were recorded in June, August and October. Natural enemies of the scale consisted of the parasitoids Aphytis lepidosaphes Compère and Encarsia sp. (Hymenoptera: Aphelinidae), which together parasitized up to 32% of L. beckii as well as the predators Chilocorus bipustulatus (L.) and Rhyzobius lophanthae Blaisdell (Coleoptera: Coccinellidae).
