Galina BUSMACHIU, Lidia TODERAS is important to protect the useful insect. During the blooming of trees and crops, T. hirta may damage 70% of the blossoms on young cherry trees [15, 22]. Many modern studies include the methods of practical control of this pest using synthetic floral attractam [11, 24, 26—28, 31 etc]. The present study was carried out in the sour cherry orchard and personal garden in the Republic of Moldova. Materials and methods The study was conducted between March and June 2014 at the sour cherry orchard with surface of 4 ha and adjacent neighbourhoods covered by whitethorn, drier, locust tree and herbaceous plants; personal garden with different types of trees (apple, apricot, quince, sour and sweet cherry, peach, pear, plums, etc.), berry bushes and herbaceous plants (blackberry, chokeberry, currant, narcissus, raspberry, strawberries, etc.) with surface of 0,7 ha in the central part of the Republic of Moldova. The specimens of pest were collected manually from the different flowers. The literature data were used also. Results and discussions As a result of the personal study and according to scientific publications the species T. hirta use as a food source more than 70 plants species from 24 families. In certain types of plant genera like Brassica, Prunus, Rosa the pests attack all species. Because of the worm winter 2013—2014 the spring came early in the Republic of Moldova and the garden flowers bloom in the middle of March, earlier than usual. The first specimens of Tropineta hirta were seen feeding on narcissus flowers in personal garden in March; as a result the flowers were eaten completely. Then, with the beginning of the other plants flowering, the pests resettled and move from one plant species to another (Fig. 1, 2, 3). Fig. 1: T. hirta feeding on Brassica rape flowers. Fig. 2: T. hirta into sour cherry flower. The species of plants consumed by T. hirta according to literature data and personal observation (PO) are listed in Table 1. The list of plant families is given in alphabetical order [33]. 124
