RESUMO

ABSTRACT: Plant resistance is the most important method of spittlebug control. The example of this utilization happened in 1980`s, when the Brachiaria brizantha cv. Marandu took place the B. decumbens. Since B. brizantha cv. Marandu is resistance to Deois flavopicta spittlebug damage, it could solve the economics damage in savannas pastures in that time. Nowadays, the genus Mahanarva has been attacking and cause widespread damage in B. brizantha cv. Marandu pastures in savannas and Amazonia Legal sites. Likewise, the Embrapa Breeding Program has a challenge in order to develop Brachiaria cultivar with spittlebug resistance performance. Besides, the use the biotechnology tools to manage the problem about apomixia in Brachiaria genus the Entomology studies is the key point. In this work, the information about the CIAT methodology is described as a good model of spittlebug rearing and resistance studies. That information was got in the training carried for researchers of Embrapa at CIAT.
