Insecticidal effect of carrot (Daucus carota) and lovage (Levisticum officinale) (Apiaceae) extracts against Tribolium confusum Jacquelin du Duval, 1868 (Coleoptera, Tenebrionidae)

Abstract

Extracts from Daucus carota and Levisticum officinale in different concentrations were tested for insec- ticidal effect against Tribolium confusum (Coleoptera, Tenebrionidae). The efficacy of treatment was evaluated after 24, 48 and 72 h. The required data were statistically analysed using the Henderson-Tilton method. The Daucus carota IPM extract in a dose of 1ml, D. carota IPM extract diluted with water in a ratio of 1:1 (dose 1 ml) and Levisticum officinale extract in a dose of 2 ml were highly efficient.
