摘要: It has been suggested that previous infection by a vascular fungus causes induced resistance against two-spotted spider mites. To test the generality of this phenomenon, series experiments was carried out using two lines tomato, differing only in againstFusarium. In addition, tests were done order to see whether defense response also affects phytophagous mite directly. Inoculation tomato plants with (Fusarium oxysporum f.sp.lycopersici race 1) prior infestation mites caused decrease rate oviposition (Tetranychus urticae) on aFusarium-susceptible line, but when moderately severely wilted. Spider did not change significantly previously inoculatedFusarium-resistant line.
