The present study was undertaken to assess the side-effects of chlorpyrifos on springtails. ants and oribatid mites associated with the soil surface of no-tillage cornfields in Brazil. Three 0.3 ha cornfields were divided into plots and, during tasseling. the plants in areas to be treated were sprayed twice with insecticide. with a 3 day interval. Pitfall traps were used to sample soil arthropods 1 week before and 1, 2, 3, 4, 5 and 8 weeks after spraying. Principal components analysis detected no negative effect of insecticide chlorpyrifos on the assemblage of soil arthropods. Nonetheless, the activity of the ant Solenopsis saevissima (Fr. Smith) was lower 2 weeks after spraying but recovered afterwards, while the frequency of Ectatomma brunneum Fr. Smith, was significantly reduced only at the third week after spraying, and did not show any recovery until the end of the study. Chlorpyrifos did not decrease the overall abundance of Collembola. However, it had a significant impact on the members of the order Symphypleona. there being significantly lower captures of Sminthurides spp. soon after chlorpyrifos spraying without any sign of increase afterwards. There was no effect on oribatid mites. Our results, overall, suggest that the impact of chlorpyrifos on soi! arthropods from tropical crop fields can be less severe than expected. |
