Selective effects of the extract from Angelica archangelica L. against Harmonia axyridis (Pallas)?An important predator of aphids
Original language description
Effects of the extract from Angelica archangelica seeds on Acyrthosiphon pisum, pea aphid mortality was tested in laboratory conditions. The total yield of the extract was 12.5%, and the undertaken analysis demonstrated a high content of furanocoumarinswith a major compounds imperatorin (50.4%), bergapten (17.9%) and phellopterin (12.2%). The extract proved to be highly toxic for the aphids and LC50 was estimated as 1.1, 0.8 and 0.4 mg L1, and LC90 as 8.7, 5.6 and 3.3 mg L1 for 24, 48 and 72 h from application, respectively. The effect of extract application on Harmonia axyridis was studied. Topical application was found to cause only low mortality (15.2%) in the 2nd?3rd instar larvae. No significant negative effect of the extract on food intake, mortality or fertility of adults was recorded. Based on present knowledge, we can recommend extracts from A. archangelica seeds for the development and production of new botanical insecticides.
