Se estudiaron las interrrelaciones del perforador del fruto del tomate Neoleucinodes elegantalis (Lepidoptera: Pyraustidae) con el ambiente, en una siembra de tomate no perturbada (sin aplicacion de plaguicidas), localizada en Quibor, estado Lara, Venezuela, durante el segundo semestre de 1983. Los resultados senalan que esta especie prefiere colocar sus huevos entre el caliz y el fruto, mas que sobre el fruto, el caliz o el pedunculo floral. Esta preferencia parece ser un mecanismo de proteccion contra el efecto letal que podrian ejercer factores ambientales, parasitos, depredadores o cualquier otro factor de mortalidad. Hubo un menor parasitismo por Trichogramma en huevos colocados entre el caliz y el fruto en comparacion con otros sitios de deposicion. Se observo la preferencia de esta especie por colocar sus huevos en frutos pequenos para asi asegurar el desarrollo larval. En cuanto a las perforaciones de entrada, se encontraron en frutos pequenos, aunque estas persisten cuando el fruto esta desarrollado. Las perforaciones de entrada fueron localizadas mayormente en la parte media inferior del fruto y esto quizas se debe a que Phthorimaea operculella y Scrobipalpula absoluta prefieren atacar el fruto en la parte media superior, por lo que se deduce que N. elegantalis penetra en regiones sin dano. Las perforaciones de salida pueden localizarse en cualquier parte del fruto. El sitio escogido para pupar fue dentro del suelo. |

Climate change can have a plethora of effects on organisms above and below the ground in terrestrial ecosystems. Given the tremendous biodiversity in the soil and the many ecosystem functions governed by soil organisms, the drivers of soil biodiversity have received increasing attention. Various climatic factors like temperature, precipitation, soil moisture, as well as extreme climate events like drought and flood have been shown to alter the composition and functioning of communities in the soil. Earthworms are important ecosystem engineers in the soils of temperate and tropical climates and play crucial roles for many ecosystem services, including decomposition, nutrient cycling, and crop yield. Here, we review the published literature on climate change effects on earthworm communities and activity. In general, we find highly species- and ecological group-specific responses to climate change, which are likely to result in altered earthworm community composition in future ecosystems. Earthworm activity, abundance, and biomass tend to increase with increasing temperature at sufficiently high soil water content, while climate extremes like drought and flooding have deleterious effects. Changing climate conditions may facilitate the invasion of earthworms at higher latitudes and altitudes, while dryer and warmer conditions may limit earthworm performance in other regions of the world. The present summary of available information provides a first baseline for predictions of future earthworm distribution. It also reveals the shortage of studies on interacting effects of multiple global change effects on earthworms, such as potential context-dependent effects of climate change at different soil pollution levels and across ecosystem types.
