Abstract
The box tree moth Cydalima perspectalis (Walker, 1859) (Lepidoptera: Crambidae), dangerous pest boxwood plants in East Asia (China, Japan and Korea), is currently officially present in 35 countries of the Europe. In the plantations of Buxus sempervirens in the central zone of the Republic of Moldova, a new invasive pest C. perspectalis was revealed in several localities. As a result of studying the biological peculiarities, it was found that the phytophage develops in the republic in three generations, wintering at the stage of larvae of 2-3 ages. The flight of imago in spring begins in May, the next generations appear in the middle and end of summer. Flight of imago and oviposition can continue until September-October with overlapping generations. The development of eggs at a temperature of + 25 ± 2 oC continued 3-5 days on average, the development of larvae was 20-36 days, the stage of the pupa – 12 ± 1.0 days. Lowering the temperature increased the duration of each stage. Moldovan populations box tree moth, as well as all the other populations described earlier from Asia and Europe, have several different types of wing colouring – typical (white), intermediate and melanic morphs. Pest monitoring is required to control population density. To manage the density of pest populations, it is necessary to use both traps with sex pheromone and microbiological and chemical preparations, depending on the situation.
