Abstract

The purpose of the research conducted was to define the impact of the various aqueous extract concentrations, prepared from the dried (in concentrations 2%, 5% and 10%) and fresh (in concentrations 10%, 20% and 30%) tansy (Tanacetum vulgare L.) mass, on the feeding of pea leaf weevil (Sitona lineatus L.), and the mortality rate of black bean aphid (Aphis fabae Scop.). The studies showed that in order to limit the feeding of pea leaf weevils considerably, it is necessary to use at least 5% extract of the dried tansy mass or 20% extract of the fresh tansy mass. The impeding effect on the feeding of pea leaf weevils was correlated positively with the extract concentration. The insecticide effect of the aqueous extract of tansy on black bean aphid was revealed not earlier than after 12 hours with the use of at least 20% extract of the fresh tansy mass and 5% extract of the dried mass (only in relation to aphid larvae). Nevertheless, also the extracts of lower concentration demonstrated insecticide effectiveness although the delayed one (36 – 60 hours after the application). As compared to other research conducted according to the same methodology, it was demonstrated that tansy aqueous extracts are characteristic for a high deterrent activity in relation to pea leaf weevil beetles (higher than the extracts of absinthe and similar to the extracts of pepper mint and sage) and a quite high aphicidal activity (higher effectiveness than in the case of the aqueous extracts of lemon balm but lower than the extracts of tarragon and absinthe).
