The effects of Arthrobotrys conoides, Duddingtonia flagrans, Paecilomyces lilacinus, Paecilomyces variotii, Monacrosporium doedycoides and an isolate of rhizobacterium on reproductivity of Meloidogyne javanica and M. incognita race 3 on Santa Clara tomato plants, susceptible to Meloidogyne spp., were studied in three different environments: 1) greenhouse without temperature control; 2) room with air temperature controlled at 24ºC; 3) watherbath with soil temperature controlled at 29-30ºC, placed in the room with the temperature controlled at 24ºC. Greatest M. javanica and M. incognita race 3 reproductivity occurred in waterbath warmed soil than in greenhouse and temperature controlled room. Galls number caused by M. javanica and M. incognita race 3 was greater in waterbath warmed soil and temperature controlled room than in greenhouse. In waterbath warmed soil and in temperature controlled room, A. conoides and rhizobacterium reduced (P< 0,05) the galls number of M. incognita race 3 compared to control. A. conoides also reduced the eggs number of M. incognita race 3 compared to control in waterbath warmed soil. In greenhouse, all antagonistics used reduced the eggs number compared to control.
