Abstract
Summary The studies were conducted on cucumber cultivar Aramis, treated and not treated with biostimulants: Asahi SL and Siapton 10 L in the glasshouse of the Warsaw University of Life Sciences and in the Laboratory of Entomology Department. Plants were cultivated in two glasshouse chambers and western flower thrips (Frankliniella occidentalis Pergande) was introduced to one of the chambers. The aim of the study was to evaluate if application of biostimulants to cucumber crop can increase the level of plant tolerance to thrips. Intensity of growth, photosynthesis and yield were compared in the plants treated and not treated with biostimulants. Cucumber plants tolerated injuries caused by thrips. They accelerated the growth and photosynthesis intensity in the first 4 weeks of pest feeding. This phenomenon was more evident in the plants treated with biostimulants, especially with Siapton 10 L. The yield was not significantly affected by thrips and biostimulants after 4 as well as after 6 weeks of thrips feeding.

Summary
Porównywano intensywność wzrostu i fotosyntezy oraz plonowanie uszkodzonych roślin, traktowanych i nietraktowanych biostymulatorami. Rośliny ogórka wykazywały znaczną zdolność do tolerowania uszkodzeń wywołanych żerowaniem wciornastka zachodniego, przyspieszając wzrost i intensywność fotosyntezy w pierwszych 4 tygodniach żerowania szkodnika. Czy zastosowanie wybranych biostymulantów roślin w uprawie ogórka, zaatakowanej przez wciornastka zachodniego, może przyczynić się do zwiększenia poziomu tolerancji na żerowania szkodnika.
