The use of biorational pesticides in the integrated protection system of stone fruit crops in the conditions of the Republic of Moldova against pests and diseases has contributed to the preservation of natural entomofauna in plum and peach orchards. The application of the natural insecticide Pelecol (8.0 l/ha) has reduced the density of aphid colonies (Hyalopterus pruni) both on plum and peach trees less than threshold values. The population of the natural predators was higher than in the chemical standard. Among aphidophagous in plum and peach tree orchards, the following species predominated: Coccinella septempunctata, Harmonia axyridis and Adalia bipunctata) (Coleoptera: Coccinellidae); Chrysopa carnea and Chrysopa formosa (Neuroptera: Chrysopidae), as well larvae and imagoes of syrphid (Diptera: Syrphidae). The following species were met in sufficient amounts Forficula auricularia, F. tomis (Dermaptera: Forficulidae), as well as representatives of the class Arachnida (Aranea). In both orchards of plum and peach trees, the species H. axyridis dominated among Coccinellidae. It was established that the reduction of chemical treatments, as well as the placement of forest shelter belts along orchards contribute to the accumulation of biota and increase the amount of predators in orchards, thus favouring the quality and quantity of the obtained crop. |
