    Pepper weevils (Anthonomus eugenii) were exposed to volatiles from Capsicun annuum, from five aromatic crops (Ocimum basilicum, Allium wakegi, Tagetes erecta, Plectranthus amboinicus and Cymbopogon citratus) and from mixes of C. annuum and each of the aromatic crops in a “Y” tube olfactometer. Volatiles from P. amboinicus, C. citratus and T. erecta were repellent to A. eugenii. Volatile of P. amboinicus + C. annuum, C. citratus + C. annuum and T. erecta + C. annuum were repellent. Contact of the weevils with the vegetative material from each aromatic crop and from C. annuum was evaluated at different times (5, 15, 30 and 60 min.) using Petri dishes. P. amboinicus, C. citratus, T. erecta and O. basilicum materials repel A. eugenii contact at all the times. C. citratus present a total repellency (0% contact) at all the times. The unique mix treatment which showed repellency to the contact with pepper passing 30 min. was C. citratus + C. annuum. A repellency to the contact with the aromatics of treatments P. amboinicus + C. annuum, C. citratus + C. annuum and T. erecta + C. annuum was shown at all the times.
