    Planococcus spp.: behavior and monitoring in conilon coffee crops
    (Editora UFLA, 2021) Borghi, Edinei José Armani; Fornaciari, Gabriel; Vieira, Mayara Leite; Aguiar, Ronilda Lana; Holtz, Anderson Mathias; Verdin Filho, Abraão Carlos; Comério, Marcone; Andrade Júnior, Saul de; Carvalho, José Romário de
    The damage caused by the citrus mealybug attack, Planococcus spp., on Coffea canephora crops is becoming more and more frequent, and may cause losses close to 100%. Knowledge of aspects related to pest behavior and adoption of methods to monitor crop incidence are important tools for integrated pest management. Thus, the objective was to study the behavior of citrus mealybug along the phenological stages of C. canephora and to propose methods to monitor its occurrence in the crops. The study was carried out in an area consisting of adult C. canephora plants of the variety Diamante ES 8112. The study was carried out using four sampling methods: 1) soil and root sampling with a probe; 2) opening small trenches; 3) plagiotropic branches and 4) weed sampling. Evaluations were carried out monthly by checking and confirming the presence of citrus mealybug in the sampled regions. The information obtained was used to describe the behavior of citrus mealybug and to analyze the applicability of the monitoring methods studied. In the absence of the reproductive phase, citrus mealybug lodges in the root system of coffee and weeds, in the region close to the colon, moving to the aerial part of the plants (rosettes) at the beginning of the flowering of the crop. Probe sampling was not efficient, while opening small trenches is a difficult procedure and causes damage to the root system of the coffee tree. The sampling of plagiotropic branches and weeds allows the monitoring of citrus mealybug duringall the phenological phases of C. canephora.

    New management technology for arabica coffee: the cyclic pruning program for arabica coffee
    (Editora UFLA, 2016-10) Verdin Filho, Abraão Carlos; Volpi, Paulo Sérgio; Ferrão, Maria Amélia Gava; Ferrão, Romário Gava; Mauri, Aldo Luiz; Fonseca, Aymbiré Francisco Almeida da; Tristão, Fabiano Alixsandro; Andrade Júnior, Saul de
    This study aimed to better understand the productive behavior of Coffea arabica when cultivated using the new management of Cyclic Pruning Program for Arabica Coffee (CPPAC), stablished using the same principles of the Cyclic Pruning Program for Conilon Coffee. The experiment was carried out in Baixo Guandú, Espírito Santo state, in the Southeast region of Brazil, in order to test the conditioning of this new pruning management for Arabica coffee (CPPAC) over the crop yield of a plantation of Catuaí Vermelho IAC 81. It was found increased crop yield with use of the (CPPAC) over the traditional management of Arabica coffee, considering five consecutive years of production. The (CPPAC) technique can be used as a viable alternative for pruning management of Arabica coffee.
