“…Predatory wasps are the principal natural enemies of CLM and regulate pest populations under field conditions (TUELHER et al, 2003;PEREIRA et al, 2007;SCALÓN et al, 2011). High abundances of natural enemies in organic farming systems have also been previously reported (ALTIERI & NICHOLLS, 2004), probably due to lower anthropogenic disturbance and higher plant diversity (BIANCHI et al 2006).…”

“…The coffee leaf miner (CLM) Leucoptera coffeella (Lepidoptera: Lyonetiidae) is one of the key pests of coffee plantings and is reported in coffee growing regions throughout the world (PEREIRA et al, 2007;SCALÓN et al, 2011;RIGHI et al, 2013). The CLM larva mines the palisade parenchyma, prevents photosynthesis (NEVES et al, 2006), and may result in yield losses of 50% if control measures are not adopted (REIS & SOUZA, 1996).…”

“…Furthermore, secondary pest outbreaks, mostly of the red mite Oligonychus ilicis McGregor (Acari: Tetranychidae), have also been reported after spraying of pyrethroid insecticides (COREDEIRO et al, 2013). Moreover, many insecticides used to control CLM have resulted in the death of predatory wasps or at least reduced wasp activity (FERNANDES et al, 2013), resulting in losses to the coffee agroecosystem, in which wasps are important natural enemies of CLM (TUELHER et al, 2003;PEREIRA et al, 2007;SCALÓN et al, 2011).…”

The infestation of coffee leaf miner and its predation by wasps were assessed in commercial organic coffee plantings shaded with leucaena or intercropped with pigeon pea. Plantings in northern Paraná were assessed every two weeks from June 2011 to December 2012. The percent of infested leaves, number of mines per leaf and the percent of predation by wasps (indicated by lacerations) were determined. Fewer coffee leaf miners and fewer mines per leaf were found in pigeon pea intercropped plantings (28.4% and 0.3, respectively) than in shaded plantings with leucaena (48.1% and 0.8, respectively). More predation by wasps was found in the shaded (27.2%) than in the intercropped (13.2%) plantings. Suggestions for new studies are presented along with suggestions for managing the leaf miner in coffee plantings.

“…Several studies indicate that the main predator wasps' species of the leaf miner that occur in the coffee plants are Polistes spp., Polybia spp., Protonectarina sylveirae (de Saussure, 1854), and Brachygastra spp. (GRAVENA, 1983a;TOZATTI;GRAVENA, 1988;PEREIRA et al, 2007;SCALON et al, 2011), where the genera Polybia spp. and Polistes spp.…”

The coffee leaf miner (CLM) Leucoptera coffeella has a wide distribution and causes significant losses in coffee plantations (Coffea spp.) in Brazil. Its occurrence can be mitigated in intercropped systems, with the rubber tree (Hevea brasiliensis ) adapting well to the consortium, while also providing extra income to the producer. We aimed to determine whether the afforestation influences the microclimate and affects the leaf miner incidence and its predation by wasp in coffee plants intercropped with rubber trees. The study was undertaken in state of Paraná, Brazil, using coffee plants intercropped with rubber trees planted in double rows (alleys) spaced at 13, 16 and 22 m between alleys, and compared to sole cropping coffee plots. From January 2008 to November 2010, the presence of CLM's lesions including those with signs of wasp predation was monitored in coffee plants intercropped with rubber trees and in the non-consorted coffee. A higher CLM's incidence was verified in monoculture coffee plots, while coffee plants located under and two meters away from rubber trees had the lowest incidences. CLM's incidence in intercropping system got higher as it increased distance from the trees. The number of lesions with signs of predation by wasps was positively correlated with the number CLM's lesions, indicating a density-dependent predator-prey relationship. The coffee plants intercropped with alley rubber trees reduce the CLM's occurrence and can be a management's tactic for this economically important pest.

“…Um dos fatores que mais contribuem para prejuízos nesta atividade é a incidência da ferrugem (Hemileia vastatrix Berkeley e Broome) que, em altos níveis, pode reduzir em mais de 50% a produção das lavouras (ZAMBOLIM et al, 1997). Assim, conhecer a dinâmica da distribuição espacial e temporal de doenças na cafeicultura pode ser importante no manejo integrado, sendo que esta técnica já vem sendo empregada em alguns estudos com pragas na cafeicultura (SCALON et al, 2011).…”

O estudo ocorreu na Fazenda Escola do IFSUDEMINAS-Campus Inconfidentes, em uma lavoura de café da Cultivar Catuaí. Foi utilizada malha amostral com 42 plantas georreferenciadas com GPS Garmim, nas coordenadas UTM 23k. A amostragem para ferrugem, produtividade, análise química e de textura ocorreu nas plantas georreferenciadas e vizinhas, localizadas nos pontos cardeais à planta central. Os resultados demonstraram forte dependência espacial para porcentagem de folhas com ferrugem do cafeeiro. Nas análises das demais variáveis foi possível detectar correlação inversa da incidência da ferrugem com as variáveis pH, soma de bases, potássio, matéria orgânica e argila. Conclui-se, portanto, que a ferrugem do cafeeiro apresenta comportamento diferenciado ao longo da lavoura e também em tempos diferentes. Verifica-se correlação entre ferrugem e as variáveis estudas. O estudo da distribuição espacial dos componentes do solo permite um manejo pontual da fertilidade, estratégia esta que pode refletir na incidência do patógeno.Abstract -The objective of this work is to study the incidence and severity of rust in coffee crop through spatial distribution at different times, and also to correlate these distributions with yield data, texture and soil chemical properties, in order to associate this information with management strategies. The study was performed at IFSUDEMINAS Farm School Campus, Inconfidentes, in a Cultivar Catuícoffee crop. It was used a sampling grid composed by 42 plants georeferenced with GARMIN GPS, in UTM coordinates 23k. Rust sampling, productivity and chemical and textural analysis occurred in georeferenced and neighboring plants, located at the cardinal points of central plant. The results showed strong spatial dependence percentage of leaves with coffee rust. In other variables analyzes, could be detected inverse correlation between incidence of rust with pH, sum of bases, potassium, organic matter and clay. Therefore, coffee rust has different behavior over the crop and also at different times. There is correlation between rust and studied variables. The spatial distribution study of soil components allows timely management of fertility; strategy that may reflect the incidence of pathogen.
