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...
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...
Population dynamics of Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychida...
Franco, Renato André; Reis, Paulo Rebelles; Zacarias, Mauricio Sergio; Altoé, Bernardo Falqueto; Neto, Marçal PedroOligonychus ilicis (McGregor, 1917) (Acari: Phytoseiidae) is considered one of the main phytophagous mites of coffee plants (Coffea spp.). Although not considered as principal, it was already referred as the second in importance for the Conillon coffee plant, Coffea canephora Pierre & Froehner. It is commonly in equilibrium, probably due to the presence of natural enemies, among them predatory mites belonging t...
Biological aspects of Chrysoperla externa (Hagen) preying on Oligonychus ilicis...
Neto, Marçal Pedro; Carvalho, César Freire; Reis, Paulo Rebelles; Santa-Cecília, Lenira Viana Costa; Souza, Brígida; Alcantra, ElianaThe red mite Oligonychus ilicis (McGregor, 1917) and the mealybug Planococcus citri (Risso, 1813) are considered important pests of the coffee plant (Coffea arabica L.), causing yield losses. The predator Chrysoperla externa (Hagen, 1861) is associated with those pests. The objective of this work was to evaluate the development of the immature and adult phases of the predator fed, in the immature phase, on thos...
Selectivity of agrochemicals on predatory mites (Phytoseiidae) found on coffee ...
Reis, Paulo Rebelles; Franco, Renato André; Neto, Marçal Pedro; Teodoro, Adenir VieiraAn evaluation on the effect of agrochemicals to the predatory mites Euseius alatus DeLeon, 1966, Euseius citrifolius Denmark & Muma, 1970, Amblyseius herbicolus (Chant, 1959) and Iphiseiodes zuluagai Denmark & Muma, 1972 (Phytoseiidae) is presented in this paper. These predators are frequently associated to Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae), vector of the coffee ring spot vir...
