The aim of the study was to evaluate the effect of the fenugreek Trigonella foenum-graceum L. on the feeding of the pea aphid Acyrthosiphon pisum Harris on peas Pisum sativum L. The parameters derived from 8-hour EPG (Electrical Penetration Graph) recordings were analysed. The following combinations were studied: peas covered with the extract from the fine ground seeds of the fenugreek, peas watered with the extract from fenugreek seeds, peas grown together with fenugreek, and peas grown in the soil with the addition of the fenugreek ground seeds. The results have shown that the fenugreek did not reduce the feeding of the pea aphid on peas. The phloem sap ingestion predominated in aphid activities in almost all combinations. The penetration of extra-phloem tissues prevailed only on plants grown together with the fenugreek. The longest time spent on phloem sap ingestion by A. pisum was found on control plants and plants watered or covered with the fenugreek seed extract.
