It generates direct and indirect jobs, and foreign exchange, with Brazilian Arabica coffee production estimated between 42 - 46 million bags (60 kg) in 2020. It is the main agribusiness activity in the State of Espírito Santo, Brazil with expected production between 13 - 15 million bags, and around 30% of this production is Arabica coffee. Technologies are recommended to coffee growers to increase yield, and production of specialty coffees on sustainable properties. Among the principles of integrated management is the monitoring of pests and diseases to determine the level of pest control. The estimate of the number of leaves to be sampled in the monitoring becomes an important tool to increase the accuracy of the obtained information. This research was carried out aiming to determine the minimum number of leaves necessary to evaluate the infestation of brown eye spot (BES) of coffee in Arabica coffee (Coffea arabica L.) without affecting the accuracy of the collection method. It was observed that the estimate of the minimum number for sampling was 46 leaves for the characteristics of incidence, and severity of BES in Arabica coffee. The modeling applied in this study allows to conclude that it is possible to recommend an optimum number of Arabica coffee leaves for these edaphoclimatic conditions, and variety, and it can serve as a basis for monitoring in an integrated pest and disease management program in Arabica coffee.

Scale insects are important coffee pests, and 73 species of Cerococcidae (3), Coccidae (18), Diaspididae (6), Eriococcidae (1), Ortheziidae (3), Pseudococcidae (21), Putoidae (2) and Rhizoecidae (19) have been associated with roots, branches, leaves, flowers and fruits of Arabica coffee in the Neotropics. Eight species were found associated with Arabica coffee in Minas Gerais and Espírito Santo States in this study, and Coccidae was the most frequent family. Coccus alpinus, Cc. celatus, Cc. lizeri, Cc. viridis, and Saissetia coffeae (Coccidae) were found in both states; Alecanochiton marquesi, Pseudaonidia trilobitiformis (Diaspididae), and Dysmicoccus texensis (Pseudococcidae) were only found in Minas Gerais. Alecanochiton marquesi and P. trilobitiformis are first reported in Minas Gerais, and Cc. alpinus in Espírito Santo, on Ar...

Because M. hirsutus is a potential pest of many plant species and may become more widely established in South America, pheromone traps may be useful for detecting entry into new areas and monitoring this mealybug. Although M. hirsutus has been recorded on a diverse variety of plants, apparently few are favored hosts, and in most areas where it has become established natural enemies maintain populations of this mealybug below damaging levels, indicating that besides prevention of spread of this pest, efforts should be directed toward establishment, augmentation, and maintenance (conservation) of effective natura...

Dentre elas a goiabeira (Psidium guajava L.), hospedeira da mosca-das-frutas em vários estados brasileiros (ZUCCHI, 2007). Os picos populacionais da mosca-sul-americana Anastrepha fraterculus (Wiedemann). O trabalho teve o objetivo de realizar a flutuação populacional de tefritídeos no município de Alfredo Chaves, Espírito Santo, Brasil, conhecer os fatores que favorecem sua ocorrência e os períodos em que sua população pode aumentar acima do nível de dano econômico.

Nowadays, it is being studied the use of several ecological methods against this pest in some Mediterranean countries (Spain, Morocco and Tunisia), like the Sterile Insect Technique (SIT), the classical biological control (CBC) and the search for native parasitoids. Two exotic larval - pupal parasitoids of fruit-flies have been imported by the IVIA to Spain: Diachasmimorpha tryoni and D. longicaudata. As it occurs in other countries, in Spain it is being studied the combined use of the SIT and overflooding releases of parasitoids to combat Medfly populations. To achieve this, only one parasitoid species is usually mass reared and released. Over the last two years we have been analyzing the competitiveness of D. longicaudata and D. tryoni in order to choose the species to be used together the SIT for the integra...

This research was conducted to identify Collembola species present in the soil of papaya orchards in Espírito Santo, Brazil, and to compare the effect of conventional and integrated production on Collembola in this Neotropical environment. Soil samples (4.8 cm diameter, 10 cm deep) were collected in February, May, August and November 2003, from papaya orchards managed with conventional production (including pesticide application based on little or no pest monitoring or consideration of environmental impact) and integrated production (including selective pesticide application only when necessary based on regular pest monitoring) in one experimental site with three treatments (conventional; integrated with drip irrigation; integrated with microsprinkler irrigation) and four commercial or...

These pests cause direct and indirect damage to papaya and other plants, and some species of this group are of quarantine importance and, thus, affect export and import of papaya fruit. To determine which species of scale insects commonly occur on papaya in Brazil, a survey of the scale insects on this crop was conducted over four years in commercial orchards located in the principal production regions of papaya in this country. Six species of scale insects were collected: Aonidiella comperei McKenzie, Coccus hesperidum L., Dysmicoccus grassii (Leonardi), Phenacoccus solenopsis Tinsley, a Pseudococcus species, and Selenaspidus articulatus (Morgan). The armored scale A. comperei often causes severe damage to the crop and was the most common and widely distributed scale insect species found on papaya in Brazil in this study. This is the first report of A. comperei on papaya in the States of Bahia, Ceará, Minas Gerais, and Paraíba, and of Co. hesperidum on papaya in Bahia, Ceará, and Rio Grande do Norte, Brazil. Information on the geographic distribution of scale insects that have been recorded on papaya worldwide and in Brazil is summarized.

This is also the first record of Co. longulus in Brazil. Information on the host plants and geographic distribution of the 26 species of scale insects of the families Coccidae, Pseudococcidae, Ortheziidae, and Monophlebidae, currently known from Espírito Santo is provided.
