Resumen en inglés

We aimed to estimate population densities of Anastrepha obliqua (McQuart) (Diptera: Tephritidae) from trap data by releasing known numbers of sterile adults into mango orchards, and to determine sterility induction through the use of different sterile-to-wild ratios in field cages. Population densities were monitored with Multilure traps baited with hydrolysed protein (Captor 300) or BioLure during dry and rainy seasons. There was a positive relationship between the release density of sterile flies and the number of flies trapped per day (FTD index) for both attractants and in both seasons. Captor was the most effective lure. Traps baited with either attractant captured significantly fewer adult flies in the dry season than in the rainy season. A 10:1 sterile:wild ratio induced around 80% sterility in A. obliqua cohorts. No significant differences were observed when comparing the release of both males and females vs. only males. These findings can support area-wide integrated pest management programs for application of the sterile insect technique to suppress or eradicate this fruit fly pest.

Resumen en español

La mosca del Mediterráneo, Ceratitis capitata (Diptera, Tephritidae), es una plaga originaria de África con un alto potencial invasivo, que se encuentra establecida en Guatemala. Esta plaga presenta variaciones poblacionales asociadas a fenómenos climáticos globales que provocan cambios en las temperaturas, precipitaciones, los cuales tienen repercusión en la fenología de sus hospedantes. El poder predecir el nivel poblacional de la mosca representaría un apoyo en la programación de las actividades de control. En este trabajo se desarrolló un modelo predictivo de la fluctuación poblacional de C. capitata, y se generó información sobre la diversidad y el flujo genético entre las poblaciones de diferentes regiones de Guatemala. También se determinó la fluctuación poblacional de la especie en áreas donde no se realizan actividades de control, y la duración del ciclo biológico a diferentes altitudes. El análisis genético indicó una diversidad moderada (Ho = 0.28) y una diferenciación leve entre poblaciones. Los resultados de la estructura genética se agruparon a las poblaciones de la región occidente y a las poblaciones del oriente de Guatemala, lo cual fue concordante con el análisis filogenético.

La fluctuación poblacional se asoció con la disponibilidad de hospedantes, temperatura y precipitación. La densidad poblacional se incrementó en relación directa con la altitud y la abundancia del café y cítricos como naranja y mandarina. La duración del ciclo de vida fue regulada por la temperatura, y su duración fue estimada con precisión empleando los umbrales y requerimientos térmicos de los modelo de Tassan. En el modelo de estimación poblacional en cafetales o áreas marginales se emplearon como variables la temperatura media, mínima y máxima, precipitación, la densidad inicial y la presencia del hospedante primario. Este modelo se ajustó a los datos en un 70% durante el periodo de estudio, con una fluctuación cíclica de las poblaciones. Un aumento de temperatura en 0.2 °C representa cambios mas aparentes que con un 10% de incremento en la precipitación. Sin embargo, es necesario realizar validación del modelo en áreas infestadas bajo diferentes condiciones ambientales.

Resumen en inglés

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is an exotic pest of economic importance in several parts of the world. Systems for monitoring this pest employ mainly trimedlure (TML), a parapheromone specifically for males. Understanding the performance of these attractants under different conditions should contribute to better design trapping networks, better field data interpretation, and a more efficient use of the products. In this study, the release rate of TML was determined at 15, 25, and 35 °C, through plug weight loss over 80 d in a bioclimatic chamber. The attraction of TML of different ages was determined in field cage tests located in a mango orchard. Our results showed a direct relationship between TML release rate and temperature. Attraction was dependent on release rate. We found that TML storage for >4 yr at 27 °C affected the quantity of the active ingredient available for release. The results are discussed in terms of the effects of these conditions on the effi- ciency of trapping networks used for the detection of this pest and quality assurance for detection programs.

Resumen en español

El uso de cebos con insecticidas es uno de los métodos más comunes y eficaces en diversas regiones del mundo para el control de moscas de la fruta (Diptera: Tephritidae). Sin embargo, esta estrategia ha sido cuestionada debido a la contaminación ambiental y los efectos no deseados en organismos no blanco. El uso de dispositivos de atracción y muerte llamados estaciones cebo (BS) o el trampeo masivo pueden ser métodos de control alternativos para superar estos impactos ecológicos. En este estudio se evaluaron diferentes dispositivos usados para el trampeo masivo y atrayentes en comparación con aspersiones terrestres de insecticidas cebo para el control de Anastrepha obliqua (Macquart) y Anastrepha ludens (Loew) (Diptera: Tephritidae) en huertos de mango en Chiapas, México. Se encontró que el contenedor de plástico de 2 litros cebado con Cera Trap®, proteína hidrolizada enzimáticamente, a una densidad de 25 trampas por hectárea fue el más eficaz en la reducción de las poblaciones de mosca de la fruta. Nuestros resultados indican que el uso de estaciones cebo puede ser tan eficaz como las aspersiones terrestres de cebo tóxico, pero superior bajo condiciones de lluvia. Lo anterior resulta de gran ventaja teniendo en cuenta las condiciones climáticas tropicales de varias zonas de producción de mango en el mundo.

Resumen en inglés

The use of insecticide baits is one of the most common and efficient methods worldwide to control fruit flies (Diptera: Tephritidae). However, this strategy has commonly been associated with environmental contamination and undesirable effects on non-target organisms. The use of lure-and-kill devices (bait stations) or mass trapping could be alternative control methods to overcome these ecological concerns. In this study, we evaluated several mass trapping devices and attractants in comparison with ground-applied insecticide bait sprays for the control of Anastrepha obliqua (Macquart) and Anastrepha ludens (Loew) (Diptera: Tephritidae) in mango orchards in Chiapas, Mexico. Among the bait stations evaluated, we found that a wide-mouth 2 L plastic bottle baited with Cera Trap®, an enzymatic hydrolyzed protein, and used at the density of 25 traps per ha was most efficient at reducing the fruit fly populations. Our results showed that bait stations to control fruit flies, in addition to using less insecticide, were as effective as ground sprays and were superior under rainy conditions. These properties represent a great advantage considering the tropical conditions in several mango production zones around the world.

Resumen en inglés

BACKGROUND: Anastrepha fruit flies are considered one of the main phytosanitary problems for the fresh fruit industry in the USA, Caribbean islands and Latin America. Since 1994, the Mexican government has implemented the National Fruit Fly Program using an area-wide integrated pest management approach. In this paper, we evaluate the effectiveness of mass trapping and compare it with ground GF-120 spraying against Anastrepha obliqua and Anastrepha ludens populations in mango cv. Ataulfo orchards. RESULTS: Multilure® traps baited with Ceratrap® or Biolure® captured significantly more fruit flies than Captor 300 in field cage tests. Mass trapping and ground GF-120 spray significantly suppressed fruit fly populations compared with untreated plots. In Multilure traps placed in untreated plots, we captured significantly more fruit flies than in treated plots with mass trapping or GF-120 sprays. Plots treated with either mass trapping or GF-120 sprays reduced the percentage of infested fruit significantly compared with untreated plots. There was no difference between mass trapping and GF-120 ground bait spraying. CONCLUSION: Our results demonstrate that mass trapping was as effective as GF-120 ground spraying for the control of fruit flies in mango cv. Ataulfo orchards. The suppression effect of mass trapping was similar to GF-120 ground bait spraying.

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 inglés

Population fluctuations of Ceratitis capitata (Wiedemann) were evaluated over a period of 12 mo in four altitudinal strata (400–750, 750–1,100, 1,100–1,450, and 1,450–1,800 meters above sea level, masl) in Eastern Guatemala. Within each altitudinal range, sampling plots were established in coffee plantations and adjacent areas, in which Jackson traps were set and baited with Trimedlure. Coffee berries and other host fruits were collected. Population density was lowest at the 400–750 masl stratum and highest at 1,450–1,800 masl. At every altitudinal range, the fluctuations of the pest were associated mainly with the availability of ripe coffee berries as a primary host. From 750–1,450 masl, the pest was also associated with the availability of sweet orange and mandarins in commercial and backyard orchards. The highest densities of the pest were recorded in the dry season. Citrus were the main alternate host where ripe coffee berries were not available. This knowledge on population dynamics of C. capitata will contribute to develop more effective area-wide pest management strategies including the use of sterile insects, natural enemies, and bait sprays.

Resumen en inglés

The relationship between different release densities of sterile flies and fly trap captures, expressed as flies per trap per day, in the monitoring of Anastrepha ludens (Loew) populations was evaluated in mango orchards. The induction of sterility in fertile females was evaluated using different ratios of sterile: fertile males under field cage conditions. A direct relationship between recaptured flies and densities of release sterile flies was found. However, trap efficiency, expressed as percentage of recaptured flies, decreased as the density of released flies increased. Sterility induction was positively correlated to the ratio of sterile: fertile flies. A significant difference in egg fertility among treatments was observed. The trajectory of sterility induction slowed down after a sterile: wild ratio of 30:1, which suggests that this ratio could be appropriate in an sterile insect technique program with A. ludens. Sterility induction was greater when only sterile males were released than when releasing both sterile males and females, but the differences were not significant. Our findings contribute to a better interpretation of fly captures obtained from the field trapping networks, and to an improvement in the efficiency of sterile insect technique against A. ludens fruit flies, through the implementation of more rational sterile fly release densities.

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.
