Effect of water extracts from Artemisia absinthium L. on feeding of selected pests and their response to the odor of this plant

2016, 17 (1)   p. 188-206



The aim of this study was to determine the effect of water extracts from fresh and dry matter of Artemisia absinthium L. on the feeding of selected pests. Moreover their reactions on the smell of this plant by using the olfactometer were examined. Beetles feeding intensity assessment was carried out by measuring the surface of feeds caused by Sitona lineatus L. In the case of Acyrthosiphon pisum Harris contact poisoning on mortality of adults and larvae were tested. In determining the effect of extracts of A. absinthium L. on Leptinotarsa decemlineata Say. food weight eaten by adult beetles and larvae and changes in larvae body weight were established. In studies on the olfactory reaction of above mentioned insects, for S. lineatus and L. decemlineata glass olfactometer "Y-tube" was used and for winged A. pisum females - 4-armed arena olfactometer. The results of the experiment showed that extract from dry matter of A. absinthium L. at concentration of 10% greatly reduced feeding of Sitona lineatus L. The highest mortality of A. pisum Harris was observed in objects in which extracts from dry and fresh matter of the highest concentrations (10% and 30% respectivelly) were applied. Extract from fresh matter in concentration of 30% made the greatest contribution to reduce feeding of L. decemlineata Say, while extract made from the dry matter at concentration of 10% significantly contributed to reduce the weight of food eaten by the larvae of this pest. Studies using the olfactometer showed a strong deterring reaction of odors derived from A. absinthium L. in relation to S. lineatus (both males and females) and males of L. decemlineata Say.
