Selecting a binomial regression model on the predation rate of Euseius concordi...
Liska, Gilberto Rodrigues; Silveira, Erika Carla da; Reis, Paulo Rebelles; Cirillo, Marcelo Ângelo; Humada Gonzalez, Guido GustavoThe red spider Oligonychus ilicis (McGregor, 1917) (Tetranychidae) has proven to be a major cause of problems in coffee (Coffea spp.). Chemical control has been widely used to control this mite, however, the existence of the adverse effects of its application has generated concern regarding its use. An alternative to this method is the biological control of pests by natural predators, among them mites of the ge...
Influence of the weeds management on the mite diversity in organic coffee crop
Neto, Marçal Pedro; Reis, Paulo Rebelles; Silva, Rogério Antônio; Zacarias, Mauricio SergioThe control of pests, diseases and weeds become an obstacle to food production in an organic system. Studies demonstrate that the management of weeds in coffee decreases the number of insects with the potential to become pests and provides increased natural enemies, and consequently keeps the pests at low levels, without causing damage. Of pest mites, Oligonychus ilicis (McGregor), Brevipalpus phoenicis (Geijsk...
Chemical control of the coffee berry borer with Cyantranilipole
de Souza, Júlio César; Reis, Paulo Rebelles; Silva, Rogério Antonio; Carvalho, Thiago Alves Ferreira de; Pereira, Andreane BastosHypothenemus hampei (Ferrari, 1867) (Coleoptera: Curculionidae, Scolytinae) is a worldwide coffee pest. It is the most important pest to Coffea canephora Pierre & Froehner and the second to Coffea arabica L. in Brazil. The chemical control is the most efficient method to its control and the endosulfan is the most efficient chemical. This ciclodieno chlorinated compound is permitted in Brazil until July 2013...
Influence of rainfall on abundance of mites in coffee plants
abreu, Fernanda aparecida; Reis, Paulo Rebelles; Marafeli, Patricia de Padua; Silva, Rogério Antonio; Bernardi, Leopoldo Ferreira de OliveiraThe coffee plant Coffea spp. suffers pest attack, which according to climatic conditions present in the culture system can reduce fruit production. Rainfall is considered an important natural factor in the regulation of arthropods populations. The objective of this study was to evaluate the effects of rainfall during the seasons, on the occurrence of the main species of mites in coffee. The experiment was carri...
Acarofauna associated with coffee shrubs in relation to the distance of forest ...
Carvalho, Thaiana Mansur Botelho; Reis, Paulo Rebelles; Silva, Ester Azevedo; Teodoro, Adenir VieiraThe conversion of natural habitats into agriculture ones and the simplification of the structure of landscapes are the main causes of the global loss of biodiversity. Agroecosystems, especially monocultures, normally provide food resources and benefit organisms only when surrounded by forests. Mites (Arachnida: Acari) are one of the most diverse groups of arthropods and contribute to the function of ecosystems ...
Selectivity of Rynaxypyr for three species of Phytoseiid mites relevant to coff...
Reis, Paulo Rebelles; Franco, Renato André; Silva, Fábio M. AndradeAmong the predaceous mites, those of the Phytoseiidae family are the most important and studied. The phytophagous mites Brevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae) and Oligonychus ilicis (McGregor, 1917) (Tetranychidae), on coffee trees (Coffea spp.), are frequently found in combination with the predaceous mites Iphiseiodes zuluagai Denmark & Muma, 1972, Amblyseius herbicolus (Chant, 1959) and Eu...
Influence of rainfall on mite distribution in organic and conventional coffee s...
Neto, Marçal Pedro; Reis, Paulo Rebelles; Zacarias, Mauricio Sergio; Silva, Rogério AntônioClimate changes, such as temperature rise, prolonged drought and heavy rainfall, impairs man’s life and food production. Rainfall is one of the most important natural, life-sustaining factors on the planet and it is essential in agriculture, not only in the watering of plants, but also in regulating pest organisms in crops, through mechanical control. The mites Brevipalpus phoenicis (Geijskes, 1939) and O...
Control of coffee plant (Coffea arabica L.) pest-mites with a physiological eff...
Reis, Paulo Rebelles; Altoé, Bernardo Falqueto; Franco, Renato AndréBrevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae) is an important coffee (Coffea arabica L.) pest-mite, because it is the vector of coffee ring spot virus, which is responsible for leaf fall and bad quality of the coffee beverage. Oligonychus ilicis (McGregor, 1917) (Tetranychidae) is also important because it reduces leaf photosynthesis area. Phytoseiidae mites are efficient predators of the phytophagous ...
Life history of Amblyseius compositus Denmark & Muma preying on Brevipalpus pho...
Reis, Paulo Rebelles; Teodoro, Adenir Vieira; Pedro Neto, MarçalPredatory mites belonging to the Phytoseiidae family, among them Amblyseius compositus Denmark & Muma, 1973, have been found in coffee plants (Coffea arabica L.) and adjacent forest fragments in of Lavras, MG, Brazil, associated to the Brevipalpus phoenicis (Geijskes, 1939) (Tenuipalpidae), Which is the vector of the coffee ring spot virus. The biological aspects, fertility life table, predatory activity, and f...
Predation potential of three species of phytoseiids on Oligonychus ilicis (McGr...
Franco, Renato André; Reis, Paulo Rebelles; Zacarias, Mauricio Sergio; Altoé, Bernardo FalquetoSome species of mites, that cause losses in coffee beans production and quality are among the organisms that attack coffee plant (Coffea spp.). The Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae), also known as coffee red spider mite, is one of the main phytophagous mites.. Mites belonging to the Phytoseiidae family are considered the most important among predatory mites. The objective of this ...
