Raluca STAN, Ion MITREA

Abstract


Buxus sempervirens Linné is one of the most cultivated ornamental species, but in recent years it has faced a dangerous pest, Cydalima perspectalis (Walker) (Lepidoptera: Crambidae) native to the Asian Continent (China, Japan, Korea). In 2019 we conducted some investigations on the life cycle of this pest. The research was carried out both in the laboratory and in the field, in the ‘Al. Buia’ Botanical Garden from Craiova. Under laboratory conditions, this species has developed four complete generations, and the fifth generation, partial. The temperature in the laboratory was between 23.5°C-26°C, and the photoperiod during the study was between 12-15 hours of light and 12-9 hours of darkness. In the field this pest has developed three complete generations and the fourth was partial. The number of days for the generations developed in the laboratory is 272 days, and for the field population 286 days.
