“…These last ones have been proposed elsewhere (Villacorta et al, 2001 andBarrera et al, 2004) and farmers use both due to their availability, without information about their relative efficiency. Red traps were also used because previous studies reported an attraction of coffee berry borers to the red color which mimic the color of ripe berries (Mendonza Mora, 1991;Giordanengo et al, 1993) and were prepared by coating transparent bottles with red paint (Coral Dulux ® , 350 red). Traps were baited with an Ethanol : Methanol mixture (1:1).…”

“…Scolytids are attracted to ethanol (E) (Moeck et al, 1981) and methanol (M) (Moeck, 1970) and this is also true for CBB in the field (Mendonza Mora, 1991;Mathieu et al, 1999). It is probable that the conditions under which coffee is grown (climate, spacing, shade, cultivar, plant age, wind direction, speed etc) may affect trapping efficiency.…”

“…This can induce some discrepancy in results involving capture of CBB in response to semiochemicals, which may interact with other factors. For example, some studies show a decreasing capture of CBB with the increase of release rate of 1:3 E:M mixtures (Mendonza Mora, 1991;Mathieu et al, 1997) while others presented the opposite effect (Borbón-Martinez et al, 2000). Red traps captured more CBB than white traps under semi natural conditions (Mathieu et al, 1997) but the opposite occurred in another field study (Borbón-Martinez et al, 2000).…”

Traps lured with semiochemical have been proposed to manage the coffee berry borer, coffee planting is however made under several environmental conditions that may affect the efficacy of traps. Several trap designs and variations were proposed and, therefore, a series of field experiments was carried out to capture coffee berry bores in traps disposed in a low density coffee plantations in the Northern part of the State of Paraná, Brazil. Traps were composed of plastic bottles (2 L) with a window (13 × 18 cm). Ethanol (E), Methanol (M) and coffee oil alone did not improve the capture when transparent traps with a 2 mm hole in the vial dispenser were used; traps lured with E : M mixtures (1:1, 1:2, 1:3) caught similar and higher number of insects than the control. There was synergism with the mixing of E and M; the addition of coffee oil to the mixtures did not improve the capture. Trap lured with E : M (1:1) mixtures at 342, 400, 428 and 710 mg caught similar numbers of insects. Transparent green trap, transparent trap and red trap lured with 642 mg day -1 of the E + M (1:1) mixture caught similar numbers of insects. Interaction between colors (transparent green, transparent and red) and semiochemical release rates (540, 720 and 1100 mg day -1 ) was observed. Transparent green trap, when lured with 720 mg day -1 of the 1 : 1 E : M mixture caught 2.3 and 4.4 times more insects than 540 and 1100 mg day -1 ; and caught 3.2 times more insects than transparent and red trap at the same release rates.

O cafeeiro é cultivado em condições ambientais diversas que podem afetar a eficiência das armadilhas. Vários modelos de armadilha e variações nos modelos são utilizados. Uma série de experimentos de campo objetivou avaliar capturas da broca-do-café em armadilhas numa lavoura de café semi-adensado no Norte do Paraná. Uma garrafa plástica (2 L) com uma abertura (13 × 18 cm) constituiu a armadilha. O etanol (E), metanol (M) e óleo de café, sozinhos, não incrementaram as capturas quando se utilizaram armadilhas transparentes com um frasco difusor com furo de 2 mm; armadilhas iscadas com as misturas 1 : 1, 1 : 2 e 1 : 3 de etanol (E) + metanol (M) capturaram quantidades similares e superiores à testemunha; sinergismo ocorreu pela mistura de etanol e metanol; a adição do óleo de café às misturas não incrementou as capturas. Armadilhas com taxas de liberação da mistura E:M (1:1) de 342, 400, 428 e 710 mg dia -1 capturaram quantidades similares. Armadilhas verdes transparentes, transparentes e vermelhas, iscadas com E:M (1:1) (642 mg dia -1 ) capturaram quantidades similares. Foi observada interação entre as cores (verde transparente, transparente, vermelha) e taxas de liberação dos semioquímicos (540, 720 e 1100 mg dia -1 ). Armadilhas verdes transparentes,...

“…Nesta fase, são atraídas por compostos voláteis dos frutos, etanol (E) e metanol (M), porém quando ainda não saíram dos frutos, estas fêmeas não apresentam respostas a estes semioquímicos (MATHIEU et al, 1991). Já em relação às respostas a estímulos visuais, todas as fêmeas mostram-se responsivas.…”

Todavia, os resultados de estudos envolvendo a seleção de cores por fêmeas da broca-do-café são conflitantes, reforçando a hipótese de que vários fatores, além da cor, estão envolvidos no processo de localização e colonização de frutos de café por fêmeas de H. hampei (MENDONZA-MORA, 1991;FRÉROT, 1997a).…”

O papel das armadilhas com semioquímicos no manejo da broca-do-cafe, Hypothenemus hampeiRecebido para publicação 27/09/05 Aprovado em 07/06/06 REVISÕES / REVIEWS O papel das armadilhas com semioquímicos no manejo da broca-do- café, Hypothenemus hampeiThe role of semiochemical traps in the management of coffee berry borer Hypothenemus hampei Flávia Cloclet da Silva 1 ; Maurício Ursi Ventura 2* , Lauro Morales 3 ResumoA broca-do-café é a praga mais importante do cafeeiro. Provoca prejuízos em quantidade e qualidade da produção. Normalmente, é controlada por aplicações de inseticidas. Estratégias alternativas de manejo são necessárias principalmente pelo aumento da produção e demanda por produtos orgânicos. O uso de armadilhas para manejo da broca é revisado. A cor, o modelo da armadilha, os atraentes e as taxas de liberação são fatores diretamente relacionados com a eficiência das armadilhas. Metanol e etanol são os compostos utilizados como atraentes. Ocorrem interações entre estes fatores na atração da broca. As condições ambientais nas quais o cafeeiro é cultivado também devem influenciar as capturas. Estes aspectos podem explicar algumas diferenças em resultados de alguns estudos. Resultados conflitantes também são verificados no que se refere à eficiência das armadilhas quando utilizadas como estratégia única de controle no campo. Pesquisas adicionais devem ser incentivadas para entender com mais profundidade as interações entre a broca e a planta de café. Da mesma forma, deve-se estudar as interações dos vários fatores intrínsecos das armadilhas e destes fatores com o ambiente no qual a armadilha será instalada. O uso das armadilhas, associadas a outras estratégias de redução populacional da praga, é prática recomendável para manejo da broca. Palavras chave: Semioquímicos, manejo, atraentes, armadilhas. AbstractThe Coffee berry borer (CBB) is the most important pest in the coffee plantings. Losses are due to quality and quantity reductions. In most plantings, CBB is controlled using insecticides. Alternative management strategies are strongly demanded due to increasing production and demand for organic products. This paper revises the use of traps for CBB management. Color and trap designs, attractants and release rates are the factors directly related to trap efficiency. Methanol and ethanol mixture is used as attractant. Interactions among these factors in the CBB attraction are reported. Environment conditions under which the coffee plantings are conducted influence trap captures. These aspects may explain some differences in results for different studies. Conflicting results are also found in relation to traps efficiency when they are used as a unique control strategy in the field. Additional research may be encouraged to understand more deeply the interactions between the CBB and coffee plant. In the same way, we must study the interactions of the several intrinsic factors of the traps and the environment. The use of the trap, associated with other strategies to reduce pest population, is a recommended ...

Semiochemicals used in Host Location by the Coffee berry Borer, Hypothenemus hampei

et al. 2009

View full text Add to dashboard Cite

The coffee berry borer, Hypothenemus hampei is a serious pest in many coffee growing countries. Electrophysiological and behavioral responses of H. hampei to volatiles of different phenological stages of coffee, Coffea arabica, fruits were studied in order to identify volatile semiochemicals used in host location. Volatiles were collected from different phenological stages of C. arabica fruit by air entrainment. Electrophysiological recordings were made from insect antennae. Behavioral assays were carried out using a Perspex four-arm olfactometer. Insects spent significantly more time in the region of the olfactometer where ripe and dry fruit volatiles were present compared to control regions. Coupled gas chromatography--electroantennography revealed the presence of six electrophysiologically active compounds in C. arabica volatiles. These were identified by using GC and GC-MS as methylcyclohexane, ethylbenzene, nonane, 1-octen-3-ol, (R)-limonene, and (R)-3-ethyl-4-methylpentanol. In the olfactometer bioassay, H. hampei showed a significant response to 3-ethyl-4-methylpentanol, methylcyclohexane, nonane, ethylbenzene, and a synthetic blend of these four compounds. Attraction to the synthetic blend was comparable to that for the natural sample. The significance of the study is discussed in terms of semiochemical based pest management methods of the coffee berry borer.
