There is a need to implement a new approach to pest control in which agroecological strategies are developed and adapted in a site-specific way to highly variable and diverse farm conditions typical of farms in tropical regions such as Brazil. It has become evident that the conventional agriculture based on high use of external inputs and oriented to maximize profits, has often been detrimental and unviable when considered from social and ecological perspectives. Pest problems, for example, are generally related to high input, single-crop agroecosystems. We discuss here agroecological strategies such as conservation biological control, use of natural pesticides and selectivity of synthetic and natural pesticides as a way to conserve and increase natural enemies' efficiency in Brazilian agroecosystems. In addition, we discuss some patents related to agroecological pest management. |

Sorghum breeding programs are based predominantly on developing homozygous lines to produce single cross hybrids, frequently with relatively narrow genetic bases. The adoption of complementary strategies, such as genetic diversity study, enables a broader vision of the genetic structure of the breeding germplasm. The purpose of this study was to evaluate the genetic diversity of sorghum breeding lines using structure analysis, principal components (PC) and clustering analyses. A total of 160 sorghum lines were genotyped with 29,649 SNP markers generated by genotyping-by-sequencing (GBS). The PC and clustering analyses consistently divided the R (restorer) and B (maintainer) lines based on their pedigree, generating four groups. Thirty-two B and 21 R lines were used to generate 121 single-cross hybrids, whose performances were compared based on the diversity clustering of each parental line. The genetic divergence of B and R lines indicated a potential for increasing heterotic response in the development of hybrids. The genetic distance was correlated to heterosis, allowing for the use of markers to create heterotic groups in sorghum. |
