Abstrakt		Ideal characteristics of a plant species implemented in a trap cropping strategy are a high attractivity to ovipositing adults, and a low suitability for larval development. The potential of the crucifers Sinapis alba (L.) and Lobularia maritima (L.) as trap crops for the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) was evaluated. The larval performance on the trap crop plants compared to Brussels sprouts (Brassica oleracea) was examined in laboratory experiments. The relative preference of the trap crop plants was monitored in a field experiment. Results showed that L. maritima is a low quality host plant. P. xylostelLa larvae had a longer development time, lower survival and a lower weight on L. maritima compared to S. alba and B. oleracea. Interestingly, in the field experiment the density of P. xylostella moths was higher on L. maritima than on S. alba. Our study indicates that L. maritima is a good candidate as a trap crop for P. xylostella because it has a low preference-performance correlation: it is attractive for oviposition, but relatively unsuitable for larval development.
