摘要

The acaricidal activity of aqueous extracts obtained from 28 plant species was tested against Tetranychus urticae. The extract efficacy on the incidence of individual development stages of T. urticae on the treated plants was determined, compared to untreated plants. Of the 28 extracts, 24 showed an efficacy higher than 50%; of these, 16 extracts caused a reduction in the count of adults on the plants by more than 90% compared to the control. The counts of nymphs and eggs showed significant differences depending on the extract used. Only 13 extracts showed an efficacy higher than 50%, and only 2 extracts (obtained from Ammi visnaga and Saponaria officinalis) had more than 90% efficacy. Twenty extracts resulted in eggs reduction of more than 50% compared to the control; of these, 6 extracts (from A. visnaga, G. glabra, J. palmata, L. carthamoides, O. majorana, S. officinalis) exhibited an efficacy higher than 90%. Extracts with the highest efficacy were tested for their acute toxicity for T. urticae adults, and LD50(90) values were estimated. By comparing the confidence intervals (CI95) for individual LD50 values, extracts obtained from Saponaria officinalis roots and Ammi visnaga seeds were found to provide the significantly highest efficacies, and lethal doses (LD50) of 10.3 and 12.5 g/l, respectively, were estimated for them. However, wanting to compare LD90 values as well, we chose 5 extracts (A. visnaga, C. annum, M. × piperita, O. majorana, and S. officinalis) whose CI95 intervals overlapped (P ≤ 0.05). Based on our tests, aqueous extracts from S. officinalis roots can be recommended for the development of products which reduce the incidence of T. urticae on plants.
