Originária da região amazônica do Brasil, a mandioca (Manihot esculenta Crantz) é utilizada como alimento por mais de 400 milhões de pessoas no mundo, sobretudo nos países em desenvolvimento onde é a principal fonte de carboidrato para a população de menor poder aquisitivo (CAGNON et al., 2002). A dieta rica em carotenoides está associada à diminuição de alguns tipos de câncer, aterosclerose e degeneração macular relacionada com a idade (SCHIEBER & CARLE, 2005. A qualidade nutricional da vários acessos de mandioca, foi avaliada por CHÁVEZ et al. (2005) que constataram teores de carotenoides totais entre 1,02 a 10,40 g g-1 de mandioca fresca. sendo que os resultados obtidos sugeriram que a mandioca poderia ser uma importante fonte de pró-vitamina A para populações cronicamente desprovidas deste composto. |

Studies on the effects of human-driven forest disturbance usually focus on either biodiversity or carbon dynamics but much less is known about ecosystem pro-cesses that span different trophic levels. Herbivory is a fundamental ecological process for ecosystem functioning, but it remains poorly quantified in human- modified tropical rainforests. Here, we present the results of the largest study to date on the impacts of human disturbances on herbivory. We quantified the incidence (percentage of leaves af-fected) and severity (the percentage of leaf area lost) of canopy insect herbivory caused by chewers, miners, and gall makers in leaves from 1,076 trees distributed across 20 undisturbed and human- modified forest plots in the Amazon. We found that chewers dominated herbivory incidence, yet were not a good pre-dictor of the other forms of herbivory at either the stem or plot level. Chewing severity was higher in both logged and logged-and- burned primary forests when compared to undisturbed forests. We found no difference in herbivory severity between undisturbed primary forests and secondary forests. Despite evidence at the stem level, neither plot- level incidence nor severity of the three forms of herbivory responded to disturbance. Synthesis. Our large-scale study of canopy herbivory confirms that chewers domi-nate the herbivory signal in tropical forests, but that their influence on leaf area lost cannot predict the incidence or severity of other forms. We found only limited evidence suggesting that human disturbance affects the severity of leaf herbivory, with higher values in logged and logged-and- burned forests than undisturbed and secondary forests. Additionally, we found no effect of human disturbance on the incidence of leaf herbivory.
