Tomatoes suffer from a wide range of pests including insects like whiteflies, aphids, thrips, caterpillars, and also spider mites.Some of the insects are difficult to control with insecticides and they develop resistance to the insecticides very quickly. In addition, several of the insecticides are hazardous to the environment, which also urges for alternative solutions to the insect problem. The best strategy is to prevent the problems occurring using resistant varieties.
Resistance against insects is found in wild relatives of the cultivated tomato. In the current project we want to obtain basic information on the extent of the pest resistance identified in the in the lycopersicon group of Solanum section Lycopersicon, find out against which insects its effective and how the resistance works.
