| dc.description | This experimental work shows the results of a comparative study on the population behavior of phytophagous and natural enemies, besides the presence of virus symptoms caused by geminivirus in three tomato varieties (INCA-17, INCA-9-1 and Lignon) in the systems of monocultures and polycultures with corn. It was carried out at the experimental areas from the National Institute of Agricultural Sciences, on a compacted Red Ferralitic soil since early January up to the end of April, 1998. The treatments studied were seven: tomato-corn polycultures and monocultures of the three tomato varieties and corn monoculture. Each treatment was 20 m long by 6.3 m wide making up approximately 900 m 2 of the evaluated area. On weekly samplings, the amount of adults was evaluated by vi- sual inspection in the field, whereas immature phases and parasitoid emergence in the laboratory. It was proved that tomato-corn polyculture has a dissuasive influence on the development of pest populations in tomato crop besides enabling colonization by pest natural enemies; there were also less symptoms of virosis in polycultures than in monocultures. A varietal effect was detected on the behavior of population densities in both systems, as well as on the presence of the virus disease | |
