Effects of Artemisia dracunculus L. Water Extracts on Selected Pests and Aphid Predator Coccinella septempunctata L.

The aim of this study was to determine the effects water extracts tarragon (Artemisia dracunculus L.) on feeding intensity, mortality, and weight gain selected pests, i.e., adult pea leaf weevils (Sitona lineatus L.), nymphs, wingless females black bean aphids (Aphis fabae Scop.), L2 L4 larvae Colorado potato beetle (Leptinotarsa decemlineata Say). In addition, effect voracity non-target organism Coccinella septempunctata L. L3 examined. To reduce S. feeding, at least 10% dry matter (DM) extract 20% fresh (FM) should be used. Tarragon has strong aphicidal potential against A. fabae, with 84% mortality nymphs 30% FM 78% DM after 108 h exposure. Aphid turned out more sensitive prepared from than its matter. They were also females. body significantly reduced through application 5% matters, respectively, while ineffective. susceptible larvae, which suggests that they used as early possible in pest season. No negative influence voraciousness C. found.
