Abstract

Summary. Cicadatra persica Kirkaldy 1909 (Hemiptera: Cicadidae) damages apple trees in Erneh (33°21′ N, 35°52′ E), a village located in the Alsheikh mountain in south-western Syria. In this study, the numbers of eggs per egg nest and of egg nests per tree, as well as their relation with the numbers of emerged adults, was estimated. The mean number of eggs per nest was 154.3 ± 90.48. There was a positive correlation among the three variables egg nest length (L), number of slits (S), and eggs (E) per nest. The best model for predicting egg numbers (E) was E = –16.145 + 12.688 S. Mineral oil (3%) applied on egg nests on apple trees did not reduce cicada hatch. Biological and cultural options such as the development of biopesticides rather than oil and insecticides should be considered as more sustainable means for controlling C. persica in fruit orchards.
