Abstract Uncovering the entire process of oviposition could enable development innovative pest control strategies. The European grapevine moth Lobesia botrana as well grape berry Eupoecilia ambiguella are serious insect pests, which still threaten viticulture in many parts world. By creating an artificial semiochemical emitting surface, form a card, we tried to develop egg‐monitoring tool for these two species vineyards. idea was create decision support system that facilitates timing and necessity insecticide treatments. This article deals exclusively with initial step towards this tool: influence physical factors (colour, shape or texture) surface on behaviour L. E. under laboratory conditions. acceptance different substrates site analysed exclusive volatile organic compounds emitted by host plant. We investigated particular colours be visual stimulus trigger both species. Apparently, colour green, texture material light conditions turned out highly important stimuli oviposition.
