“…Endosulfan, an organochlorine, is still the most common treatment against H. hampei, in spite of its fungitoxic effects on Beauveria bassiana (Mourão et al 2003, Oliveira et al 2003, one of the most important, naturally occurring pathogens of coffee berry borer. Continuous utilization of endosulfan may promote the selection of populations that are resistant to the insecticide and to other products of the same chemical group (Brun et al 1989(Brun et al , 1994, as well as cause environmental problems and farmers intoxication.…”

Neotropical Entomology 34(4): 601-606 (2005) ABSTRACT -The compatibility of a commercial formula of emulsible neem oil (Azadirachta indica A. Juss.) and of aqueous extracts of neem seeds and leaves with Beauveria bassiana (Bals.) Vuill. was evaluated in vitro. Three experiments were conducted to evaluate the effect of each product on the fungus vegetative growth and on conidia production and viability. The products were incorporated to a culture medium (BDA+E) and distributed into petri dishes, in the following concentrations: 0.15%; 1.5% and 15% (leaf aqueous extract), 1%; 2% and 4% (seed aqueous extract) and 0.5%; 1% and 1.5% (emulsible oil). Vegetative growth and conidia production were the basis for characterization of the aqueous extracts of seeds and leaves and of the emulsible oil, using the T classification model for compatibility of products. Seed and leaf extracts were less harmful to B. bassiana than the emulsible oil. Under the tested concentrations, the oil was not compatible with B. bassiana, inhibiting conidia vegetative growth significantly and decreasing production and viability of conidia, particularly at higher concentrations. Neem seed and leaf extracts were compatible with the entomopathogen in all concentrations. The seed extracts reduced conidia vegetative growth and production, but it did not affect the viability of spores. Leaf extract at 15% had a small negative impact on vegetative growth, and on production and viability of conidia, but it was still compatible with the fungus B. bassiana, according to the T model.

“…The reference resistant strain (R) was derived from a sample (sample size, N = about 1000 fertilized females) from Ponerihouen in New Caledonia (Brun et a!., 1989). It was inbred in the laboratory for 11 generations, subjected to selection by endosulfan insecticide every generation, with 100 to 1000 [R] fertilized females retained for the next generation.…”

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 ...
