Statistical comparison of the spatial distribution of both coffee leaf miner an...
Costa, Franciella Marques da; Alves, Gabriella de Freitas; Scalon, João Domingos; Zacarias, Mauricio SergioThe coffee plant is subject to pests that can cause considerable damage to the producer. The pest that concerns most the Brazilian coffee growers is the coffee leaf miner (Lepidoptera: Lyonetiidae). One way to make the biological control of the coffee leaf miner is through predatory wasps (Hymenoptera: Vespidae). Researchers claim that for performing this type of control is important to know the spatial distrib...
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...
Space-time analisis of level infestation of the coffee-leaf-miner Leucoptera co...
Scalon, João Domingos; Silva Mateus, Ana Lúcia Souza; Zacarias, Mauricio SergioThe coffee leaf miner Leucoptera coffeella, (Guérin – Menèville & Perrottet, 1842) is a key pest in coffee plantations in Brazil. This pest is important because causes losses of up to 50% in the production of coffee, depending on the loss of area of the photosynthesis, as result of necrosis on the surface of the leaf. It is well known that the understanding of the spatial distribution of insects is importan...
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...
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 ...
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...
