Title
Genetic Transfer of a Twospotted Spider Mite (Acari: Tetranychidae) Repellent in Tomato Hybrids

Other claims from this paper (6)
- Observation Two tomato hybrids had repellent leaflets, showing transferred repellency.
- Observation Leaflet washes from three hybrids repelled spider mites.
- Intervention effect Removing trichome secretions eliminated repellency from two hybrids.
- Observation Repellent hybrids contained 2,3-dihydrofarnesoic acid in trichome secretions.
- Observation Sixteen hybrids were resistant in whole-leaf bioassays, but only two had repellent leaflets.
- Observation Other resistance mechanisms are inferred in the resistant wild tomato parent.
