The other type of damage is caused by the adult spittlebug, which feeds on shoot, leaves and sprouts, causing a phytotoxic response that varies among grass species used in pastures. Given the impact of this insect on forage crops, it is important to understand how global changes may influence its ecology and thus assess whether future i ...

Concern about the environmental impacts of agricultural activities has taken on a large dimension, especially in the last decade. These impacts are expressed, for example, in reduction of biological diversity, erosion and contamination of soils, silting and contamination of water springs, increase of agrochemical residues in food, among others. However, the incorporation of the concept of sustainability has led agricultural research in the growing search for alternative and sustainable models of

Society has become increasingly aware of the need to preserve the environment and health, demanding quality standards for food and agro-ecosystems. In this context, the rational use of phytosanitary products guarantees the sustainability of food production systems, mitigating, and even eliminating the effects caused by the indiscriminate use of chemical control. Other relevant aspects to be considered are the benefits arising from the crop-livestock integration that mitigate the negative effects
