Papaya ringspot, one of the most important diseases of papaya, is caused by Papaya ringspot virus type P (PRSV-P), which is transmitted by various aphid species. Objectives of this research were to identify the aphid species and their weed hosts of papaya orchards in the major papaya producing and exporting region of Brazil in northern Espírito Santo State. Aphids were collected from weed hosts, and with Möericke-type traps in papaya orchards of twenty farms in Linhares, Sooretama and Aracruz municipalities of Espírito Santo, Brazil. A total of forty aphid species were collected, of which 22 are new records in the State. Thirty-eight aphid species were identified from traps, including Aphis craccivora Koch, A. gossypii Glover, A. spiraecola Patch, Myzus persicae (Sulzer), and Toxoptera citricidus (Kirkaldy), known vectors of PRSV-P. Cryptomyzus Oestlund (Aphididae) is recorded for the first time in Brazil. Thirteen aphid species associated with 22 weed species of 14 families were collected. Aphis gossypii, which has been reported to be one of the most efficient vectors of PRSV-P, infested the greatest number of weed hosts. Chamaesyce hyssopifolia (L.) Small, Euphorbia hirta L. (Euphorbiaceae), Commelina benghalensis L. (Commelinaceae), Lepidium virginicum L. (Brassicaceae) and Sida sp. (Malvaceae) were the most frequently infested weeds. Commelina benghalensis was infested by the greatest number of aphid species during this study. Integrated management of weed hosts of aphids to reduce aphid populations in papaya orchards may be useful for control of PRSV-P. Based on accurate knowledge of the aphid and weed species present in papaya orchards obtained in this study, integrated pest management efforts may be more efficiently directed toward eliminating the most frequently infested weed species that serve as hosts for aphid vectors of PRSV-P.

The objective of this work was to evaluate the speed effect of a coffee harvester and its interaction with 'Conilon' coffee (Coffea canephora)
clones on the mechanical harvesting efficiency. The experiment was installed in São Mateus, in the state of Espírito Santo, Brazil, in 2012, with 27 clones of early, intermediate, and late fruit ripening. The first harvest was performed after the plant cuttings at 0.5 m above the ground, in 2016, and the canopy renovation. The plants and the harvester were evaluated in 2018. The coffee harvester was tested at 0.6 and 0.8 km h-1. Measurements were performed for stripping and harvesting efficiencies, fruit loss on the ground, unstripped fruit, defoliation with manual and mechanized harvesting, fruit removal force, and fruit ripening degree. The tests with the coffee harvester indicated a technical feasibility of 88% average harvesting efficiency, and a 15% lower defoliation than the manual harvesting. The harvesting speed of 0.8 km h-1 results in higher stripping and harvesting efficiencies, in a lower percentage of loss on the ground, and in less unstripped fruit, regardless of the evaluated
clones. Fruit removal force and ripening degree influence the stripping and harvesting efficiencies and the percentage of unstripped fruit of 'Conilon'
coffee.
O objetivo deste trabalho foi avaliar o efeito da velocidade de uma colheitadeira de café e sua interação com clones de café 'Conilon' (Coffea canephora) sobre a eficiência da colheita mecanizada. O experimento foi instalado em São Mateus, no Espírito Santo, em 2012, com 27 clones com frutos de maturação precoce, intermediária e tardia. A primeira colheita foi feita após o corte das plantas a 0,5 m acima do solo, em 2016, e a renovação da copa. As plantas e a colheitadeira foram avaliadas em 2018. A colheitadeira foi testada às velocidades de 0,6 e 0,8 km h-1. As mensurações foram feitas quanto à eficiência de derriça e colheita, à perda dos frutos no chão, aos frutos não derriçados, à desfolha com as colheitas manual e mecanizada, à força de desprendimento e ao grau de maturação dos frutos. Os testes com a colheitadeira de café indicaram viabilidade técnica com eficiência de 88% de colheita média e desfolha 15% menor do que a da colheita manual. A velocidade de colheita de 0,8 km h-1 resulta em maiores eficiências de derriçados e de colheita, em menores perdas no chão e em menos frutos não derriçados, independentemente dos clones avaliados. A força de desprendimento e o grau de maturação influenciam a eficiência de descascamento e de colheita e a percentagem de frutos não descascados de café 'Conilon'.
