Resumen en inglés

Despite their relevant contribution to the conservation of tropical ecosystems and crop productivity through pollination, the stingless bees (Apidae: Meliponini) can be considered a group of neglected species in the assessment of pesticides upon nontarget organisms. In this article, we evaluated the effect of aerial sprays of the spinosad-based fruit fly toxic bait GF-120 upon colonies of the stingless bee Scaptotrigona mexicana Guérin (Hymenoptera: Apidae), an economically important and abundant species in some landscapes of Mexico, located in mango orchards. Colonies of the honey bee Apis mellifera L. (Hymenoptera: Apidae) were used for comparison. Eight colonies (four of A. mellifera and four of S. mexicana ) were moved into each of two mango orchards, one was used as a control, with no insecticide application, and other received five weekly aerial sprays of GF-120. Foraging activity and strength of colonies of both species were measured nine times over the fruiting season, previous, during and after insecticide application. We did not find a significant difference in foraging activity and strength between exposed and control colonies of A. mellifera during the observation period. However, colonies of S. mexicana seemed to be affected by the exposure, as revealed by a reduction in colony strength. However, 1 yr later, with no insecticide applications, the colonies of both species were evaluated and found to be in good conditions. Our results showed that weekly aerial sprays of GF-120 are unlikely to generate acute poisoning in both species, even if in acute toxicity tests this product has been found to be highly active.

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

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

We present the results of evaluating the response of three species of bees, Trigona fulviventris (Guérin), Scaptotrigona mexicana (Guérin-Meneville), and Apis mellifera (L.), to food sources baited with the toxic bait GF-120 (NF Naturalyte), a spinosad-based bait exclusively used to manage fruit flies. Groups of foragers were trained to collect honey and water from a feeder located 50 m from the colonies. Once a sufficient number of foragers were observed at the experimental location, the training feeder was changed to two or three feeders that offered either honey and water, GF-120, Captor (hydrolyzed protein), GF-120 and honey (4:6), or Captor and honey (1:19). T. fulviventris and S. mexicana rarely visited GF-120, Captor, or their mixtures with honey, while ∼28.5 and 1.5% of A. mellifera foragers visited the GF-120 and honey and Captor and honey mixtures, respectively. Our results show that GF-120 clearly repels T. fulviventris and S. mexicana, whereas for A. mellifera, repellence is not as marked when GF-120 is combined with highly nutritious substances like honey.
