AbstractThe coffee berry borerHypothenemus hampei(Ferrari) is the most serious pest of the world's most valuable tropical export crop. Since the last review on this insect was published six years ago, many new studies have contributed to an improved insight into the biology and ecology of the beetle, and have indicated new avenues for integrated and biological control. The latest developments in research, both laboratory and field, on the pest, its natural enemies and their implications for integrated control ofH. hampeiare summarized, with a particular focus on the situation in The Americas. Lately, the global coffee industry has changed radically; it has suffered a long cycle of lowest-ever world market prices caused by overproduction and technological change. At the same time, the advent of sustainable certification schemes has had a major impact on the industry. The role of integrated pest management and biological control ofH. hampeiin an era of changes in the coffee industry is discussed.

Insight Into

Adhesion to host cells is a precursor to host colonization and evasion of the host immune response. Conversely, it triggers the induction of the immune response, a process vital to the host’s defence against infection. Adhesins are microbial cell surface molecules or structures that mediate the attachment of the microbe to host cells and thus the host–pathogen interaction. They also play a crucial role in bacterial aggregation and biofilm formation. In this review, we discuss the role of adhesins in the pathogenesis of the aetiological agent of tuberculosis, Mycobacterium tuberculosis. We also provide insight into the structure and characteristics of some of the characterized and putative M. tuberculosis adhesins. Finally, we examine the potential of adhesins as targets for the development of tuberculosis control strategies.

AbstractBiological control plays an important role in many integrated pest management programmes, but can be disrupted by other control strategies, including chemical and cultural controls. In commercial cranberry (Vaccinium macrocarpon Aiton; Ericaceae) production, a spring flood can replace an insecticide application, providing an opportunity to study the compatibility of the flood (a cultural control) with biological control. We suspect that chemical controls will tend to reduce the number of natural enemies, while the flood, through removal of detritus and detritivores, may cause generalist predators to prey-switch to consume proportionally more pest individuals. We measured the abundance of herbivores (Lepidoptera), detritivores, Arachnida, and parasitoids (Hymenoptera) every week for six weeks in Wisconsin (United States of America) cranberry beds following either an insecticide spray or a cultural control flood. We found that detritivore populations rapidly declined in both flood and spray treatments; conversely, carnivore populations (spiders and parasitoids) were more abundant in the flooded beds than in sprayed beds. Populations of key cranberry pests were similar between flooded and sprayed beds. Our results showed that early-season flooding preserved more natural enemies than an insecticide application. This increase in natural enemy abundance after the flood may allow for greater continuity in herbivore suppression, potentially providing a basis for long-term cranberry pest management.

This research evaluates biological control agents (BCAs) and fungicide alone and in combination for the management of decline caused by multiple fungi on milkwort (Polygala myrtifolia). Four experiments were performed in a greenhouse within a nursery located in Catania province (southern Italy). The activity of fungicides and biological control agents was evaluated by calculating the plant mortality (%) and recovery frequency (%) of different fungi associated with symptomatic tissue. Comprehensively, boscalid + pyraclostrobin and fosetyl-Al showed the best results in managing disease complex on milkwort. Biological control agents provided, on average, the lowest performances; nevertheless, in most cases, they were able to significantly reduce multiple infections and sometimes when combined with fungicide enhanced the effectiveness. The molecular analysis of 86 isolates obtained from symptomatic tissue allowed to identify the fungi involved in the disease as Calonectriapauciramosa, C. pseudomexicana, Fusariumoxysporum, Neocosmospora solani (syn. F. solani) and binucleate Rhizoctonia AG-R. Calonectriapseudomexicana never reported on milkwort and in Europe was inoculated on P. myrtifolia potted healthy cuttings and produced crown and root rot after 40 days. Our findings represent the first worldwide report about disease complex of milkwort caused by several fungi (Calonectria spp., Fusarium spp. and binucleate Rhizoctonia) and on the effects of integrated control strategies to manage this disease in the nursery.

Of Greece

<p>The global economic crisis in the 1890s affected the economy of Greece severely, and in 1893 the Greek State had to stop servicing its foreign debt. Part of the<br />problem was the lack of diversity of Greek agricultural production, which was focused on raisins and currants (especially flavourful raisins, grown exclusively in the area around Corinth) for export. The collapse of market prices for this good seriously affected the Greek treasury and society in the growing regions. The Greek government responded by trying to withhold part of the harvest in fertile years to stabilise world market prices. Plans to organise a monopoly company for the currant trade necessitated high sums of capital from abroad. This article investigates the question of how foreign bankers in London (Hambro &amp; Son, Emile Erlanger) and Paris (Banque de l’Union Parisienne) could be convinced to participate in the project. Which factors allowed foreign bankers to trust in the Greek national economy despite its poor reputation? What factors influenced their risk management? The focus is on the role of Greek brokers in persuading the foreigners to invest in Greece, especially the role played by Ioannis Pesmazoglou, the director of the young and innovative Bank of Athens.</p>

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%.

AbstractThe Mediterranean fruit fly, Ceratitis capitata (Wiedemann), which is often controlled chemically, is a major citrus pest in Spain; however, alternative biological control strategies such as those based on the conservation of polyphagous predators should be developed. The wolf spider, Pardosa cribata Simon, is an abundant predator found in citrus orchards in eastern Spain. In this study, we have evaluated polymerase chain reaction (PCR)-based techniques as a means of detecting C. capitata DNA remains in P. cribata specimens. To do so, two pairs of C. capitata species-specific primers were designed and tested. Primer specificity was tested on species closely related to C. capitata and with other pests and natural enemies present in citrus orchards. Medfly DNA was detectable in 100% of P. cribata from 0 to 12 h post ingestion for both primer pairs, decreasing to 37% at 96 h after prey ingestion for one pair of primers. DNA detectability half-lives were of 78.25 h and 78.08 h for each pair of primers but no statistical differences were found between them. Pardosa cribata specimens were field-collected daily after sterile C. capitata pupae had been deployed in the citrus orchard. Afterwards, the wolf spiders were analyzed and DNA remains of C. capitata were detected in 5% of them, with a peak of 15% coinciding with maximum C. capitata emergence. This study is the first to reveal the potential use of DNA markers to track medfly predation by P. cribata in citrus orchards and provides a new tool to estimate the potential role of this spider in biological-control conservation programs.

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.
