Many commercial tomato varieties are resistant against potato aphids (Macrosiphum euphorbiae) do to a single dominant gene (Mi). Understanding potential interactions between Mi-mediated resistance and other defensive pathways could enhance IPM strategies in tomato. Bioassays and molecular techniques were used to determine interactions between Mi-mediated resistance and induction of jasmonic acid (JA); an important defense elicitor against chewing insects. Mi resistance offered the greatest protection against potato aphids. Induction of JA offered some control against potato aphids and did not inhibit Mi-mediated resistance.
