Diante da crise socioambiental e econômica aliada à agricultura convencional, torna-se urgente o desenvolvimento de técnicas que contribuam para a transição produtiva do modelo atual para formas de produção mais sustentáveis. Deste modo, o conhecimento sobre a interação inseto-planta revela-se como uma importante ferramenta para elaboração de mecanismos de manejo a serem aplicados aos sistemas produtivos que privilegiem a produção orgânica. Assim, o presente trabalho faz uma revisão sobre a defesa das plantas e a sua relação com a herbivoria de insetos, direcionando, a partir das inter-relações co-evolutivas destes organismos, estratégias possíveis de utilização para o manejo de insetos considerados ?pragas? agrícolas em agroecossistemas. |

One of the most important obstacles in large-scale ecological restoration relies on the high costs of current practices of planting nursery raised tree
seedlings. Finding less expensive and ecologically viable restoration has been a challenge for scientists. We compared three techniques aiming at Cerrado
restoration in the Amazon region, Brazil: passive restoration (T1 ? abandonment) and mechanized direct seeding of native trees and legume species in
rows (T2), or broadcast (T3) (four replications each, 0.24 ha per plot). The experimental area was deforested by the 1980s and used mainly as pasture
for about 25 years, and a native forest fragment remains close to the study site. Density and richness of the woody plant community (from 50 cm in
height) has been used as indicators of restoration efficacy. At 12 months after planting, a total of 1,004 individuals of 61 species were recorded in the
survey plots (a total of 720 m²). Among these species, 14 had been seeded and the other 47 entered the community by natural regeneration processes
(resprouting or by seed rain). Neither the plant density (F = 0.53; df = 2; P > 0.05) nor the species richness (F = 2.1; df = 2; P > 0.05) differed
among the three techniques. Considering that passive restoration has no costs and its efficacy does not differ from the direct seeding, we concluded that
abandonment is the best solution to recover the highly resilient Cerrado vegetation under environmental conditions similar to the experimental area.
