A broca-do-café, Hypothenemus hampei (Ferrari) é responsável por grandes prejuízos em plantios de café, causando perdas de produtividade aos cafeicultores e danos quantitativos e qualitativos aos grãos. O controle biológico da praga tem sido principalmente à base de fungos entomopatogênicos. Em Rondônia, Brasil, as informações acerca dos parasitoides de H. hampei são escassas. O parasitoide Cephalonomia stephanoderis Betrem é um inimigo natural da broca do café e já é utilizado como agente de controle biológico em países da África e da América Latina. Constatou-se a presença desse parasitoide em cafezais de Rondônia. O objetivo do presente estudo foi investigar os níveis de ocorrência e parasitismo do parasitóide em uma plantação de café no município de Ouro Preto D’Oeste, Estado de Rondônia. Foram analisados semanalmente frutos de café coletados diretamente das plantas e caídos sobre o solo, de janeiro a dezembro de 2004. Observou-se a ocorrência do parasitoide durante os meses de maior infestação da praga. Durante o período estudado, a taxa de parasitismo nos diferentes microambientes variou de 2 a 24%. Parasitism in the Population of the Coffee Berry Borer Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae) by the Parasitoid Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidae) Abstract. The coffee berry borer, Hypothenemus hampei (Ferrari) attacks coffee plantations, greatly decreasing the production of coffee plants, causing quantitative and qualitative damage to the grains. Biological control of this pest has focused mostly on entomopathogenic fungi. In the state of Rondonia, studies on parasitism levels of the parasitoids of H. hampei are scarce. The parasitoid Cephalonomia stephanoderis Betrem is a natural enemy of the coffee berry borer and is already used as an agent of biological control in countries of Africa and Latin America. The objective of the present study was to investigate the occurrence and parasitism levels of the parasitoid in a coffee plantation in the municipality of Ouro Preto D’Oeste, State of Rondonia. Coffee beans collected directly from the plants and on the ground were analyzed weekly from January to December 2004. Parasitoid occurred in months of the highest pest infestation. During the studied period, parasitism rate in different microenvironments ranged from 2 to 24%.

AbstractCephalonomia stephanoderis Betrem and Prorops nasuta Waterston are two bethylid parasitoids obtained from Africa for the biological control of the coffee berry borer, Hypothenemus hampei (Ferrari) in Mexico and Ecuador. Rearing methods and life-cycle studies carried out under controlled conditions are described for both the parasitoids and H. hampei. Scanning electron micrographs are shown of the developmental stages of the parasitoids. Data are given on development times, pre-oviposition period and on the mating and oviposition behaviour of C. stephanoderis.

Recent Occurrence

The ceraphronid wasp Aphanogmus dictynna (Waterston) was recently recorded in error as an undescribed species of Aphanogmus. This species is a primary parasitoid on larvae and cocoons of the bethylid Prorops nasuta Waterston, and probably a second bethylid species, Cephalonomia stephanoderis Betrem. Both bethylids are primary parasitoids, and important biological control agents, of larvae and pupae of the coffee berry borer Hypothenemus hampei (Ferrari). New host and distribution records are provided for A. dictynna, as well as a diagnosis and comments on its taxonomic relationships.

Three field trials with endosulfan against coffee berry borer, Hypothenemus hampei (Ferr.), on both Coffea arabica and C. canephora are described. The insecticide was applied from motorized knapsack sprayers at 20 gal. per acre of an emulsified solution containing 0.2 per cent, active ingredient to the branches bearing the crop.In two trials endosulfan applied twice at 21-day intervals significantly reduced the numbers of cherries containing living borers and the percentage of damaged cherries at the first pick. In the third trial a single application of endosulfan proved to be as effective as the double one. Increases in yield could not be detected. It was shown, by allowing insects to emerge from caged samples of cherries taken when picking began, that endosulfan did not affect the host/parasite ratio of either H. hampei or Geratitis coffeae (Bez.), nor did it increase the numbers of berry-boring caterpillars.No off-flavours following treatment could be detected in liquoring trials of robusta coffee beans that were dry processed or pulped and washed.Laboratory experiments in which adults of H. hampei were exposed above, but out of contact with, filter papers that had been dipped in an emulsified solution containing 0·2 per cent, endosulfan showed that it was acting at least as a partial fumigant and was more effective at 30°C. than at room temperature (21°C); spraying should thus preferably be carried out on warm, sunny days. In view of these findings, and as it is relatively non-toxic, endosulfan is recommended for control of H. hampei in Uganda when heavy attacks occur.

Abstract The African parasitoids Cephalonomia stephanoderis Waterston (Bethylidae: Hymenoptera), Prorops nasuta Betrem (Bethylidae: Hymenoptera), and Phymastichus coffea LaSalle (Eulophidae: Hymenoptera) are biological control agents of the coffee berry borer (Coleoptera: Curculionidae). In this study, we investigated in laboratory the female behavioral responses of these parasitoids to 14 different wavelengths (340–670 nm) against a control (570 nm, yellow). When nonchooser females were included in the analysis, none parasitoids species showed a preference between 340, 350, 370, 460, 490, 520, 540, 590, 640, and 650 nm with respect to the control wavelength. In contrast, the three species of parasitoids were more attracted to wavelengths of 380, 400, and 420 nm than the control wavelength. Phymastichus coffea and P. nasuta were more attracted to the wavelength of 400 and 420 nm compared to C. stephanoderis. At 380 nm, P. coffea and C. stephanoderis wasps showed the higher responses in comparison to P. nasuta females. When nonchooser wasps were excluded from the analysis, we observed other differences among the parasitoid species. For instance, P. coffea were more attracted to 490–540 nm than to 570 nm, whereas the bethylids did not discriminate between 490–540 nm or 570 nm. Our results are discussed in relation to possible implications associated with the vision of these parasitoid species.

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.
