Giant knotweed, Reynoutria sachalinensis (F. Schmidt) Nakai, is a species native to the Far East, introduced in the Republic of Moldova in the 1980s. The surveys of entomofauna and mites associated with the crop R. sachalinensis were carried out in the experimental sector of the Plant Resources Laboratory of the “Alexandru Ciubotaru” National Botanical Garden (Institute). The research has revealed the structure of the entomofauna on R. sachalinensis plants during the growing season and resulted in the identification of 31 species of insects, in various growth stages, the assessment of the phytoparasitic impact, records and analyses of morphological parameters, taxonomic affiliation, trophic specialization, frequency values and abundance of entomofauna on the entire plant and the biological and ecological significance in the regulation of the ratio of zoophagous/phytophagous insects.
