El uso de la t\u00e9cnica del insecto est\u00e9ril es una de las formas de control de las poblaciones de moscas m\u00e1s amigables con el medio ambiente. Las moscas criadas en condiciones artificiales, se esterilizan y posteriormente se liberan en n\u00fameros masivos en las \u00e1reas afectadas. Por su abundancia, es m\u00e1s probable que los machos est\u00e9riles se aparean con las hembras silvestres provocando un fracaso en la reproducci\u00f3n.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">En M\u00e9xico, la t\u00e9cnica del insecto est\u00e9ril se ha utilizado exitosamente en zonas del norte como San Luis Potos\u00ed y Tamaulipas. Sin embargo, ya que estas son zonas m\u00e1s secas, las moscas criadas artificialmente pueden enfrentar una desventaja al competir con sus hom\u00f3logos silvestres. Adem\u00e1s, no hay informaci\u00f3n sobre el comportamiento sexual de esta especie en condiciones de estr\u00e9s h\u00eddrico.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">Para abordar estas preguntas, los investigadores de INBIOTECA junto con sus colegas realizaron una serie de experimentos explorando el comportamiento sexual de la mosca mexicana de la fruta bajo estr\u00e9s h\u00eddrico. El estudio fue posible gracias a una l\u00ednea de moscas resistente a la desecaci\u00f3n desarrollada por el Dr. Marco Tejeda, ex doctorante de INBIOTECA. Esta l\u00ednea es un linaje especial de moscas seleccionadas artificialmente por su capacidad para resistir el estr\u00e9s h\u00eddrico.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">La <a href=\"https:\/\/www.uv.mx\/personal\/diperez\" target=\"_blank\" style=\"color:#006699\">Dra. Diana P\u00e9rez-Staples<\/a>, autor principal del art\u00edculo, explic\u00f3 que aunque se sab\u00eda por un estudio anterior que las moscas resistentes a la desecaci\u00f3n viven m\u00e1s tiempo y se desempe\u00f1an en el cortejo de igual manera que las moscas silvestres, no se sab\u00eda c\u00f3mo el estr\u00e9s h\u00eddrico podr\u00eda afectar los componentes del eyaculado de los machos. En este estudio, los autores sugieren que las moscas resistentes a la desecaci\u00f3n presentan gl\u00e1ndulas accesorias m\u00e1s peque\u00f1as y transfieren menos espermatozoides que los machos silvestres. Esto resulta en un compromiso (trade-off) entre caracteres: las moscas invirtieron m\u00e1s recursos para sobrevivir pero relativamente menos recursos para la reproducci\u00f3n.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">Este estudio tiene implicaciones con el aumento de la temperatura proyectada por causas del cambio clim\u00e1tico. Con un aumento en el estr\u00e9s h\u00eddrico, se espera que las moscas tengan que hacer cada vez m\u00e1s compromisos en la inversi\u00f3n de recursos. Una mosca que est\u00e1 adaptada para sobrevivir bajo condiciones de estr\u00e9s h\u00eddrico, tendr\u00e1 mayor probabilidad de sobrevivir aunque invertir\u00e1 menos en el eyaculado.

One of the most environmentally friendly ways to control fly populations is through the use of the Sterile Insect Technique. Flies are reared in artificial conditions, sterilised and then released in massive numbers into the affected areas. Sterile males will then be more likely to mate with wild females leading to a failure in reproduction.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">In Mexico, the SIT has been used effectively in areas of the north such as San Luis Potosi and Tamaulipas. However, since these areas are drier, artificially reared flies may encounter a disadvantage when competing with their wild counterparts. Furthermore, there is no information about the sexual behaviour of this species under conditions of hydric stress.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">To address these questions, researchers from INBIOTECA along with colleagues carried out a series of experiments exploring the sexual behaviour of the Mexican fruit fly under hydric stress. The study was made possible thanks to a desiccation resistant line of flies developed by Dr. Marco Tejeda, a former doctoral student of INBIOTECA. This line is a special lineage of flies that was artificially selected for their ability to resist water stress.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\"><a href=\"https:\/\/www.uv.mx\/personal\/diperez\" target=\"_blank\" style=\"color:#006699\">Dra. Diana P\u00e9rez-Staples<\/a>, the lead author on the paper, explained that while it was known from an earlier study that the desiccation resistant flies lived longer and performed courtship equally than wild flies, it was not known how the hydric stress affected the male ejaculate components. In this study, the authors suggest that desiccation resistant male flies had smaller accessory glands and transferred fewer sperm. This results in a trade-off: flies invested more resources into survival but relatively lesser resources into reproduction.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">This study has implications for the projected increase in temperature caused by climate change. With an increase in hydric stress, flies are expected to increasingly make trade offs in investment of resources. A fly that is adapted to survive under these conditions will have a greater probability of reproducing successfully. The new desiccation tolerant line developed provides a valuable tool to understand the effects of climatic variables on the sexual behaviour of this species and also aid in reducing the economic damage caused to citrus crops in Mexico and other countries.<\/p>\n<p style=\"text-align:justify;padding-left:20%;padding-right:20%;color:#575757\">Citation: <span style=\"color:#3a3a3a\">P\u00e9rez-Staples, D.<\/span>, Abraham, S., Herrera-Cruz, M. et al.
