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.

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.

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.

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%.

The coffee berry borer (CBB) Hypothenemus hampei Ferrari is the most serious pest of coffee worldwide. Management of the CBB is extremely difficult because its entire life cycle occurs inside the fruit, where it is well protected. Knowing which life stages contribute most to population growth, would shed light on the population dynamics of this pest and help to improve CBB management programs. Two staged-classified matrices were constructed for CBB populations reared in the lab on artificial diets and CBB populations from artificial infestations in the field. Matrices were used to determine demographic parameters, to conduct elasticity analyses, and to perform prospective perturbation analysis. Higher values of the intrinsic rate of natural increase (rm) and population growth rate (λ): were observed for CBB populations growing in the lab than in the field (rm: 0.058, λ: 1.74 lab; rm: 0.053, λ: 1.32 field). Sensitivity values for both CBB populations were highest for the transitions from larva to pupa (G2: 0.316 lab, 0.352 field), transition from pupa to juvenile (G3: 0.345 lab, 0.515 field) and survival of adult females (P5: 0.324 lab, 0.389 field); these three vital rates can be important targets for CBB management. Prospective perturbation analyses indicated that an effective management for the CBB should consider multiple developmental stages; perturbations of >90% for each transition are necessary to reduce λ to <1. However, when the three vital rates with highest sensitivity are impacted at the same time, the percentage of perturbation is reduced to 25% for each transition; with these reductions in survival of larvae, pupae and adult females the value of λ was reduced from 1.32 to 0.96. Management programs for CBB should be focused on the use of biological and cultural measures that are known to affect these three important targets.
