A broca-do-café, Hypothenemus hampei é uma das pragas mais importantes que ataca os frutos de todas as espécies de café. No período de pós-colheita, o inseto abriga-se e sobrevive nos frutos remanescentes da colheita, que permanecem nos ramos ou caídos ao solo. A prática do repasse que consiste na coleta e retirada desses frutos da lavoura, permite a redução do índice inicial de infestação da nova safra. Com o objetivo de avaliar a ocorrência da praga, cinco meses após a colheita, nos frutos remanescentes nos ramos e caídos ao solo, montou-se o experimento em cultura de Coffea canephora. Coletou-se uma média de 66,4 frutos por planta, sendo que, cerca de 26,6 frutos encontravam-se ainda pendentes e 39,8 no solo. A média de frutos brocados por planta foi de 71,7 %, chegando a uma percentagem de 91 % de infestação dos frutos coletados nos ramos. A ocorrência de frutos com a presença natural da vespa de Uganda, Prorops nasuta, atingiu um índice de 2,3 % por planta. O número médio de adultos vivos da broca obtido por fruto brocado foi de 12,8 e 5,3 espécimens, respectivamente, para os coletados nos ramos e no solo.
In most parts of the world the coffee berry borer, Hypothenemus hampei is the important pest of coffee leading to major crop losses and decreased coffee quality. Current control measures include cultural chemical and biological strategies. Cultural control consists of manual berry collections after the harvest with the objective of carried out the major number of berries of the soil and the plant. The number of berries leaves in the plant and the soil was evaluated in crops of Coffea canephora. The average number of berries leaves by tree was of 66,4; which 26,6 berries was collected in the branches and 39,8 in the soil. The average of the infested berries was 71,7% by tree. The berries with the natural occurrence of the Prorops nasuta was 2,3% by plant. The average number of lives adults of the coffee berry borer was 12,8 and 5,3 exemplars, respectively, in the berries collected in the branches and in the soil.

This study aimed to analyze the genetic variability of Coffea canephora population with 190 genotypes from cultivar ?ES8152?, based on morphoagronomic characteristics and vegetation index, to identify the most important characteristics for genetic divergence and compare them with commercial clones. The experiment was installed, in 2019, at the Bananal do Norte Experimental Farm/INCAPER, Cachoeiro de Itapemirim, ES, Brazil. The experiment was carried out in Federer?s augmented block design with three blocks, four common treatments (commercial clones A1, LB1, V8 and V12) and 190 regular treatments, genotypes from the seed production field of the conilon coffee cultivar ?ES8152?. At 24 months of age 14 morphoagronomic characteristics and vegetation index were evaluated. Descriptive analysis of the data, the estimation of the Standardized Euclidean Distance (ED) followed by the group-ing by the methods of Tocher, UPGMA and principal coordinates, in addition to the relative importance of the characters estimated by the Singh meth-odology were performed. The most distant genotypes were 62 and 83 (ED=2.620) and the closest were 42 and 160 (ED=0.208). Genotype 83 stood out as the most distant among the others. The optimization and hierarchical groupings allowed the identification of genotypes 15, 81, 107 and 184 as similar to commercial clones. The discard analysis of variables recommended the elimination of the vegetation index and average internode length of the next diversity analysis. Principal coordinate analysis found phenotypic similarity of the genotypes 30, 81, 115, 141 and 163 with the clone V12, of the genotype 119 with the clone A1 and genotype 17 with clone LB1. The study, of morphoagronomic characters, allowed to detection the genetic diversity existing in the materials evaluated, indicating those with phenotypic similarity with the commercial clones, being possible the early identification of promising genotypes, agronomically superior, to start a breeding program for clonal selection, recurrent selection and controlled crosses to maximize heterosis.
