| Onion is the third most grown vegetable crop in São Paulo state, Brazil. Organic onion farming is expected to increase in the state due to the increasing demand. Pest management in organic onion farming is based on plant extracts with insecticide effects. However, the efficacy of such plant extracts has not been proved yet, and it was observed that they do negatively affect natural enemies. Plants surrounding onion fields, and that are attractive to natural enemies, may be a good option to farmers, since they may lead to increased diversity of arthropod species and, consequently, the natural control of pest populations. This study deals with the effect of marigold plants as a resource plant to natural enemies in onion fields. The experiment was set in a... |

| O objetivo deste trabalho foi registrar as espécies de Orius associadas a plantas cultivadas e invasoras presentes em uma localidade de Minas Gerais e três de São Paulo, nos anos de 1999 e 2000. As coletas foram realizadas através de batidas das plantas no interior de sacos plásticos para desalojar os insetos. Posteriormente, as espécies foram separadas em laboratório. O predador Orius insidiosus (Say) foi coletado nas culturas de milho (Zea mays L.), milheto (Pennisetum glaucum (L.) R.Br.), sorgo (Sorghum spp.), feijão (Phaseolus vulgaris L.), girassol (Helianthus annuus L.), alfafa (Medicago sativa L.), soja [Glycine max (L.) Merr.], crisântemo (Chrysanthemum spp.), tango (Solidago canadensis L.) e cartamus (Carthamus tinctorius L.) e nas plantas... |
