Abstract

The Damask rose is the national flower of Iran, and after Fars province, Kerman province ranks second in the country with 4,932 hectares of rose gardens. In recent years, the moth Cnaemidophorus (Eucnaemidophorus) rhododactylus (Lepidoptera: Pterophoridae) has spread across various regions of Kerman province, emerging as a significant and dangerous pest of this plant. Damage of this pest in 2017 to 2019 was 59.40, 62.59 and 66.57 percent to the buds of damask rose, respectively, which indicates the increase in pest damage. This study investigated the biology of this pest over three years, from 2017 to 2019, both in the laboratory and on the farm, in the Laleh-Zar region of Kerman province, which encompasses a vast area of rose gardens. Through the study of its biology in Kerman province, it was determined that this pest has one generation per year and overwinters as a first instar larva in diapause beneath the cover of branches. The first instar larvae emerge in mid-April and begin feeding, influenced by the average temperatures of March and April. The diapause stage of this pest lasts approximately eight months. The average number of eggs laid by each female insect was 87.62±5.30. The average development periods were calculated as 11.31±0.37 days for the egg stage, 54.97±4.08 days for the larval stage, 12.64±1.31 days for pupal stage and 15.4±2.30 days for the adult stage.
