Abstract

The Eulecanium tiliae is widely distributed in most parts of Iran, including western parts as a potential threat for different kinds of fruit trees. During 2016-2018, the morphology and biology of this pest was studied in natural conditions (Sahneh’s cherry orchard). Sampling interval times were variable throughout the growing season. The reproductive adult females were collected and reared in laboratory condition and microscopic slides were made for species identification. Overwintering stage was as second nymphal instar on 1-2 years-old  twigs. They have only one generation per year, This species appeared in considerable population on the twigs of individual cheery tree. Males were not found during the study of its life history. The reproductive female emerged in April, and began to oviposit from early May to early June. This species reproduce parthenogenetically. The number of eggs per female on, E. tiliae estimated, 570 (200-1000). The first instars appeared at the end of May, spread out and settled on both surfaces of the leaves.
