Conteúdo: | Most cultivars of apple trees are highly dependent on insects for success-ful pollination and fruit production. In this study, we evaluated the insectdiversity in apple orchards of southern Brazil and verified whether or notthere is a relationship between the diversity of insect visitors and thecharacteristics (weight, seed number, and symmetry) of the fruits of?Fuji?and?Gala?apples produced by the orchards. We also evaluated thediversity of insects on flowering weeds within apple orchards and com-pared it with the apple flowers. Diversity of anthophilous insects was low,in general, and differed between the regions. Furthermore, regarding in-sect diversity, orchards were grouped by management system: organicorchards were more similar to each other than to conventional orchards.The insect diversity of weed flowers was higher than apple flowers, butinsect abundance was greater on apple flowers, suggesting that weedsmay increase insect diversity within apple orchards and may sustain polli-nators. We found a positive effect of insect diversity on the number ofseeds of?Fuji?apples and of honeybee abundance on their weight, sug-gesting that honeybee management is important in the studied areas. Incontrast, we found no significant effect of insect diversity and abundanceon?Gala?apple characteristics. Despite this, the analyses of the seeds of?Gala?apples indicate that the orchards may suffer a pollination deficit,which could be overcome by improving insect pollination. These resultsreinforce previous findings that insect diversity is important for appleyield, but its influence varies with cultivar.
