“…Its application in agriculture has not been limited to it biocidal properties with mixed reviews reported when administered in dilution as a pesticide on cowpea weevil larvae, flies, Spodoptera frugiperda caterpillars, and wasps (Chalermsan & Peerapan 2009;Tavares et al 2010;Pangnakorn et al 2012;Achmadi et al 2013) or wasps (Mendonca et al 2006). In sharp contrast, other scientists have focused on its potential benefits in enhancing crop yields, with mixed reviews reported upon its application to French marigold, scarlet sage, zinnia, rock melon, palm phoenix when applied in diluted form (Zulkarami et al 2011;Mungkunkamchao et al 2013), and in combination with biochar/charcoal (Hua et al 1998;Kang, et al 2012;Lashari et al 2013).…”

This paper highlights the potential benefits of smoke recovery from the production of biochar in crop management through it application as an antimicrobial agent against plant disease and as a pesticide. The study reports on the findings of zone inhibition assays on selected plant pathogens ( Agrobacterium tumefacien and Xanthomonas campestris), growth studies on selected plants ( Raphanus sativus and Vicia faba), and toxicity studies performed on arthropods ( Myzus persicae and Tetranychus urticae). The results suggested a strong benefit to crop management in terms of crop protection against selected causal agents responsible for plant disease, with zones of inhibition observed on both Agrobacterium tumefacien and Xanthomonas campestris when inoculated with pyroligneous acid (liquid smoke) at 10% dilution. Similarly, its potential as a bio-pesticide are favorable, with a reported 20%-30% of arthropods affected (knocked out/mortality) after exposure for 48 hours.

“…Farmers' general lack of knowledge of the coffee entomofauna has led to extensive and indiscriminate application of chemical products. As a result, a series of disastrous environmental disturbances have aggravated many entomological problems due to the reduction of natural control agents (Parra 1985;Souza et al 1998, Mendonça et al 2006. The demand for organic products and public pressure for less aggressive crop-management practices are obligating farmers to employ new products and methods, despite the lack of information on their efficiency (Leroy et al 2000;Venzon et al 2005).…”

Influence of rubber trees on leaf-miner damage to coffee plants in an agroforestry system

et al. 2013

The coffee leaf-miner (CLM) (Leucoptera coffeella Guérin-Mèneville; Lepidoptera: Lyonetiidae), the main pest of coffee plants, occurs widely throughout the Neotropics where it has a significant, negative economic and quantitative impact on coffee production. This study was conducted in a rubber tree/ coffee plant interface that was influenced by the trees to a varying degrees depending on the location of the coffee plants, i.e. from beneath the rubber trees, extending through a range of distances from the edge of the tree plantation to end in a coffee monocrop field. The most severe damage inflicted on coffee plants by the CLM (number of mined leaves) from April, which marks the start of the water deficit period, until September 2003 was in the zone close to the rubber trees, whereas the damage inflicted on plants in the monocropped field was comparable to that on coffee plants grown directly beneath the rubber trees, which received about 25-40 % of the available irradiance (I r-available irradiation at a certain position divided by the irradiation received in full sunlight, i.e. in the monocrop). From May until July damage caused by the CLM nearly doubled in each month. In midwinter (July), the damage decreased perceptibly from the tree edge toward the open field. From September onward, with the rising air temperatures CLM damage in the coffee monocrop started to increase. Based on these results, we conclude that coffee plants grown in the full sun incurred the most damage only at the end of winter, with warming air

“…Nos últimos anos, têm-se intensificado as pesquisas buscando avaliar o efeito de produtos de origem vegetal no controle de insetos-praga (Almeida et al, 2006;Mendonça et al, 2006;Gonçalves-Gervásio & Vendramim 2007;Oliveira et al, 2007;Pereira et al, 2008;Lima et al, 2009;Rossi et al, 2010). Para exemplificar, podese citar o trabalho realizado por Santiago et al (2008) Dentre as classes de metabólitos secundários envolvidos na defesa das plantas contra a herbivoria, destacam-se os taninos, os quais são conhecidos por causarem redução no crescimento e sobrevivência de insetos (Schaller, 2008).…”

RESUMOConduziu-se este trabalho, com o objetivo de quantificar taninos condensados presentes nas cascas do caule de Ochroma pyramidalis (Bombacaceae), Schinus terebinthifolius (Anacardiaceae), Enterolobium contortisiliquum (Fabaceae) e Peltophorum dubium (Fabaceae) e verificar o efeito de frações tânicas dessas espécies sobre parâmetros biológicos e nutricionais de S. frugiperda. A partir das cascas das espécies vegetais se prepararam extratos, dos quais alíquotas foram tomadas para a quantificação dos taninos. Em seguida, os extratos foram submetidos a fracionamento para a obtenção das frações tânicas, que foram incorporadas à dieta artificial e oferecidas para lagartas de S. frugiperda. Todas as espécies vegetais estudadas apresentaram taninos condensados, sendo que S. terebinthifolius apresentou menor quantidade desses compostos. A fração tânica de P. dubium causou redução no peso das lagartas e pupas, diminuição na sobrevivência de S. frugiperda durante as fases larval e pupal, e acarretou menor consumo alimentar, além de prolongar a duração das fases imaturas desse inseto. O tratamento com S. terebinthifolius causou redução na percentagem de sobrevivência, durante a fase de pupa. Pupas provenientes de lagartas que receberam tratamento com a fração de E. contortisiliquum tiveram aumento no seu período de desenvolvimento. Lagartas alimentadas com a fração proveniente de P. dubium apresentaram a menor taxa de crescimento relativo (RGR), menor eficiência de conversão do alimento digerido (ECD) e maior custo metabólico (CM). A digestibilidade aproximada (AD) foi maior para os tratamentos com as frações tânicas de P. dubium e S. terebinthifolius. Termos para indexação: Lagarta militar, taninos condensados, produtos naturais, controle. ABSTRACTThe objective of this study was to quantify condensed tannins present in the stem bark of Ochroma pyramidalis (Bombacaceae), Schinus terebinthifolius (Anacardiaceae), Enterolobium contortisiliquum (Fabaceae) and Peltophorum dubium (Fabaceae) and to verify the effect of tannic fractions of these species on biological and nutritional parameters of S. frugiperda. Extracts were prepared from the barks of the plant species and aliquots were taken from them to quantify the tannins. The extracts were then submitted to fractionation to obtain the tannic fractions, which ones were incorporated into an artificial diet and offered to the larvae of S. frugiperda. All the studied species showed condensed tannins, and S. terebinthifolius showed the lowest amount of these compounds. The tannin fraction of P. dubium caused a reduction in the weight of larvae and pupae, decreased the survival of S. frugiperda during the larval and pupal stages and led to a reduction of intake, beyond to extend the duration of immature stages of this insect. The treatment with S. terebinthifolius caused a reduction in the survival percentage during the pupal stage. Pupae from larvae that received the treatment with the fraction of E. contortisiliquum had an increase in its development period stage. Larvae fed...
