METHOD: Feeding Behavior CONDITIONS: Green House and Field - 16h light at 24C METHOD NARR: Laboratory antibiosis tests counted and weighed mature pupae and the time it took to reach the pupal stage, after infesting tubers with laenosis tests counted leaf mines and tuber mines, and overall weight of tubers per plant at harvest. RESULTS NARR: The highest antibiosis effect expressed as total larval mortality on tubers was found in all pnt and 2 spl ceffect of tubers was observed in some spl genotypes. The wild species tested in the field antixenosis test had a low level of infestation throughout the life cycle of the plant, with little dependence on phenological factors.wide range of larval survival observed among clones derived from 2 spl PIs indicates a segregation for resistance. A polygenic or oligogenic control of the antibiosis is hypothesized. The exudate of type B trichomes had a strong antid ovipositioning females and work by other authors is mentioned regarding this influence.
