Macrolophus pygmaeus induces systemic resistance in tomato against Meloidogyne.

ABSTRACT: The ability of Macrolophus pygmaeus to induce systemic resistance in susceptible and Mi1.2 resistant tomato against Meloidogyne spp. was evaluated in 200cm³ pot experiments. The susceptible cv. Roma and the resistant cv. Caramba were exposed to 15 M. pygmaeus nymphs per plant in mesh bags for 48 h and then were inoculated with 200 stage juveniles (J2) of M. incognita or 600 J2 of a mixed community of M. arenaria, M. hapla, and M. javanica. Tomato plants were maintained in a growth chamber during 40 days. Then the number of egg masses and eggs per plant were determined. In addition, the preference of the insect was evaluated confronting nematode-infected vs. non-infected plants in a Y-tube olfactometer and in insect cages, where 10 females were released into each cage containing
