Resumen en inglés

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), is considered one of the most important pests worldwide because of its direct damage to fruit and vegetable production, and restrictions imposed to commercialization of horticultural commodities by countries free of the pest. It was introduced to Brazil in 1901 and to Costa Rica in 1955, from where it spread across the Central American region, reaching Guatemala and Mexico in 1976 and 1977, respectively. In response, the governments of Guatemala, Mexico, and the USA joined efforts to (1) contain further northward spread of the pest, (2) eradicate it from the areas it had invaded in southernMexico, and (3) in the longer termeradicate it from Guatemala and eventually from the rest of Central America. To this effect, cooperative agreements were subscribed between the three countries and also between the USA and Belize. This allowed regional cooperation against the Mediterranean fruit fly and the creation of the Moscamed Programme. The programme was the first area-wide large-scale application of the sterile insect technique (SIT) against this pest. By 1982, the Programme had achieved its first two objectives with the containment of the northward advance of the pest, and its eradication from the areas it had invaded in the states of Chiapas and Oaxaca in southern Mexico. Furthermore, by 1985 the Mediterranean fruit fly had been eradicated from areas in Guatemala located at the border with Mexico. Since then, the programme has had years with significant territorial advances in the eradication of the pest from areas within Guatemala, combined with years when it had setbacks resulting in losses of the territorial gains. Nevertheless, during 4 decades, the programme has effectively served as an effective containment barrier maintaining the Mediterranean fruit fly-free status of Belize, Mexico, and the USA.

It has also protected and increased the Mediterranean fruit fly-free areas in Guatemala. As a result, it has protected the assets of horticultural producers and contributed during this period to the development of multibillion dollar export industries in these countries. This paper provides an historical review of the programme and describes briefly how technological innovations and decision-making tools have contributed to programme efficiency. It also discusses how non-technical and external factors have limited the eradication process and further programme advance within the Central American region.

Resumen en inglés

This study reports the pathogenicity of three formulations of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales) – Bb-ET, GHA, and Bb-AES – and their application in panel-type and cylinder-type autoinoculation devices, and using sterile males as vectors for the control of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) in coffee-producing areas of the Central Highlands of Guatemala. Using sterile adults of C. capitata under laboratory bioassays, mean lethal concentrations (LC50) of 1.4 9 107, 2.4 9 106, and 8.2 9 105 conidia ml-¹, and median survival times of 4.1 0.1, 4.2 0.1, and 3.8 0.1 days, were recorded for the strains GHA, Bb-AES, and Bb-ET, respectively. These values indicate that the three strains were sufficiently pathogenic and that their period of biological activity was considered adequate for using sterile flies as vectors of the inoculum. Observed percentages of sporulated wild C. capitata flies were 57.3, 44.7, and 44.3% for sterile fly vectors, panel devices, and cylinder devices, respectively. The total population reduction at the end of the study period was over 90% for the three treatments. Our results show that sterile males used as vectors or disseminator devices may represent a new control method for area-wide integrated management of Mediterranean fruit flies. The potential of this new approach and its integration with other control methods, including the sterile insect technique, is discussed.

Resumen en español

La mosca del Mediterráneo (Ceratitis capitata, Wiedemann; Diptera: Tephritidae) es considerada como una de las plagas más destructivas en el mundo. Fue detectada por primera vez en México (en la frontera sur con Guatemala) en 1977, una vez que se había dispersado por toda la región Centroamericana. En 1982, utilizando un enfoque de MIP en áreas amplias incluyendo la técnica del insecto estéril, el Programa Moscamed, establecido por los gobiernos de México, Guatemala y Estados Unidos de América, fue exitoso en erradicar a la plaga de las áreas que había invadido en México. Entradas de plaga recurrentes en la forma de detecciones y brotes transitorios ocurren en los estados del sur de México fronterizos con Guatemala. El estatus libre de plaga se mantiene a través de acciones de erradicación cuya efectividad es verificada por medio de una extensiva e intensiva red de vigilancia que incluye 24,760 trampas. Utilizando la terminología de la Convención Internacional de Protección Fitosanitaria (CIPF), el estatus de plaga de la Mosca del Mediterráneo se puede definir para la mayor parte de México como “Plaga Ausente” (i.e. los sistemas de vigilancia confirman la ausencia de plaga en 28 de 32 estados) y como “Plaga Transitoria” (i.e. entradas de plaga que no resultan en establecimiento después de la aplicación de medidas fitosanitarias para su erradicación) para los estados fronterizos en el sur incluyendo Chiapas, Tabasco y Campeche y para Baja California estado fronterizo en el norte. La inversión tan significativa que el gobierno de México ha realizado en el Programa Moscamed por más de 30 años ha sido altamente rentable (tasa beneficio-costo de 112 a 1), cuando se compara con la industria hortofrutícola multimillonaria que se ha desarrollado durante este tiempo.

Adicionalmente, a través de los años el programa involucró a sus propios investigadores así como a investigadores en otros países y organizaciones en innovación y optimización de importantes tecnologías. Se incluye técnicas de producción para una cepa genética de solo machos, torres de emergencia para moscas adultas, máquinas de liberación aérea, insecticida cebo de origen orgánico, estaciones cebo de larga duración, trampas Fase IV y atrayentes sesgados hacia captura de hembras, uso de sistemas de posicionamiento global para análisis de datos y predicciones y para la liberación rutinaria de moscas estériles. Estas herramientas han permitido un incremento en la efectividad del programa y han sido adoptadas en muchos países.

Resumen en inglés

The Mediterranean fruit fly (Ceratitis capitata, Wiedemann; Diptera: Tephritidae) is regarded as one of the most destructive insect pests worldwide. It was first detected in Mexico (border with Guatemala) in 1977 after it had spread throughout the Central American region. By 1982, using an area-wide IPM approach that included the Sterile Insect Technique, the Moscamed Program, established by the federal governments of Mexico, Guatemala and USA, succeeded in eradicating the pest from the areas it had invaded in Mexico. Recurrent pest entries in the form of transient detections and outbreaks continue to occur in the southern-most States of Mexico bordering Guatemala. The pest free area status is maintained by eradication actions whose effectiveness is verified by an extensive and intense surveillance network including 24,760 traps. In terms of the International Plant Protection Convention (IPPC), the Mediterranean fruit fly pest status can be defined for most of Mexico as “Pest Absent” (i.e., no records of the presence of the pest confirmed by surveys in 28 States of the 32 States) and as “Pest Transient” (i.e., pest entries that do not result in establishment after applying appropriate phytosanitary measures for their eradication) for the southern border States of Chiapas, Tabasco and Campeche, and for the northern border State of Baja California. The very significant investment that the Government of Mexico has made in the Moscamed Program for over 30 years has been extremely cost-effective (benefit-cost ratio of 112 to 1), when compared to the multi-billion dollar horticultural industry that has developed during this period. In addition through the years, the program engaged its own scientists and scientists in a number of countries and organizations in innovation and optimization of important technologies.

These include production techniques for an only male genetic sexing strain, emergence towers, aerial release machines, organic targeted insecticide baits, long lasting bait stations, Phase IV traps and female biased attractants, and use of global positioning systems for data analysis and forecasting and for routing aerial releases. These tools have led to increased program effectiveness and have been adopted in many countries.

Resumen en inglés

Sterile Mediterranean fruit fly, Ceratitis capitata (Wied.), males were evaluated as vectors to spread Beauveria bassiana (Bals) conidia to wild C. capitata populations under field conditions. The inoculated sterile males were released by air, using the chilled adult technique over 7000 ha of coffee growing in Chimaltenango, Guatemala, Central America. The impact of releases was determined using dry traps baited with a food attractant. The effects of these releases on Apis mellifera, Linnaeus (honey bee), Hypothenemus hampei, Ferrari (coffee berry borer) and the parasitic mite Varroa destructor (Oudeman) were also evaluated. Inoculated sterile males were able to transmit fungal spores to 44% of the wild C. capitata flies captured in traps, which likely were infected through intra- and intersexual interactions during leks, mating or mating attempts. There was no transmission of the fungal spores to non-target insect species such as coffee berry borer, honey bees or varroa. We conclude that sterile males of Mediterranean fruit fly inoculated with B. bassiana can act as effective vectors of conidia to wild populations, constituting a safe, environmentally friendly and selective alternative for suppressing the medfly under a Sterile Insect Technique-based IPM approach.

Resumen en inglés

The virulence of two products of the fungus Beauveria bassiana (LCPP and Bassianil) on adult Anastrepha ludens (Loew) (Diptera: Tephritidae) and their effect on the mating performance of infected males was evaluated in laboratory and field cage tests. The horizontal transmission capacity of the fungus during copulation or attempted copulation also was quantified using inoculated males as well as the impact of infection on female fecundity and longevity. Both fungal products were found to be highly virulent (LCPP, mortality = 98.7% at 1 X 108 conidia per ml, LT50 = 4.20 d, LC50 = 9.35 X 105 conidia per ml; Bassianil, mortality = 99.3% at 1 X 108conidia per ml, LT50 = 4.04 d, LC50 = 2.69 X 107conidia per ml). Mating success of inoculated males was not affected compared with the control group during the 3 d postinoculation. Horizontal transmission to females during the first day was 80.6 and 84.3% through mating and 15.4 and 21.6% through attempts to mate and contact during courtship for the LCPP and Bassianil products, respectively. The fertility of infected females was notably reduced, and longevity did not extend beyond 15 d. Our results suggest the possibility of using sterile flies as fungus vectors in sterile insect technique programs, but the potential benefits and shortcomings of this approach require further investigation.
