The biology and behavior of insects are strongly influenced by environmental conditions such as temperature and precipitation. Because some of these factors present a within day variation, they may be causing variations on insect diurnal flight activity, but scant information exists on the issue. The aim of this work was to describe the patterns on diurnal variation of the abundance of Ichneumonoidea and their relation with relative humidity, temperature, light intensity, and wind speed. The study site was a tropical dry forest at Ría Lagartos Biosphere Reserve, Mexico; where correlations between environmental factors (relative humidity, temperature, light, and wind speed) and abundance of Ichneumonidae and Braconidae (Hymenoptera: Ichneumonoidea) were estimated. The best regression model for explaining abundance variation was selected using the second order Akaike Information Criterion. The optimum values of temperature, humidity, and light for flight activity of both families were also estimated. Ichneumonid and braconid abundances were significantly correlated to relative humidity, temperature, and light intensity; ichneumonid also showed significant correlations to wind speed. The second order Akaike Information Criterion suggests that in tropical dry conditions, relative humidity is more important that temperature for Ichneumonoidea diurnal activity. Ichneumonid wasps selected toward intermediate values of relative humidity, temperature and the lowest wind speeds; while Braconidae selected for low values of relative humidity. For light intensity, braconids presented a positive selection for moderately high values.
昆虫的生物学特性和行为受到温度和降水等环境条件的强烈影响。由于其中一些因素存在日内变化，它们可能导致昆虫日间飞行活动的变化，但关于这一问题的信息却很少。这项工作的目的是描述姬蜂总科昆虫数量的日变化模式及其与相对湿度、温度、光照强度和风速的关系。研究地点是墨西哥里阿拉加托斯生物圈保护区的一片热带干燥森林；在那里估计了环境因素（相对湿度、温度、光照和风速）与姬蜂科和茧蜂科（膜翅目：姬蜂总科）数量之间的相关性。使用二阶赤池信息准则选择解释数量变化的最佳回归模型。还估计了两个科飞行活动的温度、湿度和光照的最佳值。姬蜂科和茧蜂科的数量与相对湿度、温度和光照强度显著相关；姬蜂科与风速也有显著相关性。二阶赤池信息准则表明，在热带干燥条件下，相对湿度对姬蜂总科的日间活动比温度更重要。姬蜂选择相对湿度、温度的中间值和最低风速；而茧蜂科选择低相对湿度值。对于光照强度，茧蜂对中等较高的值有正向选择。
