Rezumat

The purpose of this work was to highlight one of the ecological methods of seasonal monitoring of the population density of the pest cotton bollworm, Heliothis armigera Hbn. (Lepidoptera: Noctuidae) on corn. In recent years, this pest is a particularly acute problem in the agroecosystem plantati-ons of agricultural crops. The larvae of this pest cause essential damage to a wide spectrum of agricultural plants, including the corn, which in the Republic of Moldova is the part of the economically important crops. To protect the harvest, a wide spectrum of pesticides is appli-ed and about 3-4 chemical treatments are carried out annually. In the Republic of Moldova, the areas cultivated with sweet corn constitute approximately 3000 ha annually and are con-stantly growing. At the same time, chemical treatments, along with pest control, also cause significant damage to the ecological system, which manifests itself not only through direct negative effects, but also indirect ones, which will become visible in the coming years. The widespread use of pesticides also leads directly to the considerable reduction of the beneficial insect species. Extremely important method for combating this pest is the seasonal monitoring of the population density depending on the species of cultivated plants and the phenological phases of their development. One of the effective solutions would be the development of methods based on natural control mechanisms of the relationships between harmful organisms and cultivated plants. A safe method for detecting and monitoring the population density of this pest is the application of pheromonal traps. The most important advantage of using sexual pheromones is that they are biologically active substances characteristic only for the target species and are not harmful both to the human body and to the environment [1, 2].
