ABSTRACT
The use of synthetic and chemical insecticides in the past brought several consequences for the environment that only were observed many generations after. The classic DDT case represents this fact, the “modern” synthetic insecticide created used in the US for many years to control mosquitoes and also pests in crops and livestock production, institutions, homes, and gardens (Carson, 1962). After years we realized devastating effects in humans, mammals and other non-target organisms; insecticide resistance, the concentration of chlorinated hydrocarbon insecticides in the food chain, significant declines in densities of natural enemy (predators and parasitoids) populations, secondary outbreaks of pests, resurgence of primary pests and insecticide residues on fruits and vegetables are just a few of consequences listed. In an attempt to decrease ecological impacts and preserve the environment, the scientific community and governments created politics and regulations about pesticide use. Nowadays, several countries are adopting and regulating organic farming, looking for safe consumption through the use of less synthetic inputs and also respect people, the environment and soil sustainability. However, challenges should be overcome, one of them is how to manage pest pressure and damage, excluding contaminants practices and produce enough food quantities?
