VOLATILE PROFILES OF YOUNG LEAVES OF RUTACEAE SPP. VARYING IN SUSCEPTIBILITY TO THE ASIAN CITRUS PSYLLID (HEMIPTERA: PSYLLIDAE)

require the newly expand-ing terminal leaves (flush) of citrus and related species in order to complete their development (Shavankar et al. 2000; Michaud 2004). The study presented here examined host plant vola-tiles from uninfested flush and young leaves of citrus genotypes that were reported to vary in susceptibility as measured by colonization by
