DISEASES AND PESTS ON TRIBULUS TERRESTRIS L.- WILD GROWING PLANT AND SEMI-CROP

Surveys for identification of diseases and pests attacking Tribulus terrestris L. in natural habitats and cultivated sowing of Tribulus terrestris L. were conducted. Damage caused by mildew (Phytophthora spp.) were observed during the vegetation period. Colonies of a mixed population (larvae and adults) of cotton aphid (Aphis gossypii Glov.) and damage from caterpillars (Lepidoptera:Noctuidae) were established. Caterpillars of the cotton bollworm (Helicoverpa armigera Hb.) and Leucanithis stolida F. were observed from July to August. Attack of spider mite (Tetranychus urticae Koch.) both in natural habitats and cultivated sowing was observed during the whole vegetation period.
