The present study investigated the effect of mono/bicyclic terpenoids and phenol derivatives on the viability of Drosophila melanogaster and their influence on the multiplication of the nuclear genome. The fertility and viability of fruit flies were assessed after oral administration and inhalation exposure of compounds 1-5: guaiacol, eugenol, borneol, menthol and carvacrol. The influence of terpenoids and phenols on the degree of chromosomes polyteny in salivary gland cells of D. melanogaster larvae was determined. Among all tested compounds, carvacrol demonstrated the most significant impact on fecundity and insect survival when inhaled or adding to the culture medium. Oral administration of carvacrol had an impact on giant chromosomes increasing their average level of chromosome polyteny degree while eugenol adding to culture medium had the opposite effect. The possible mechanism of terpenoids and phenols action is discussed.
