Fenología de los bracónidos (hymenoptera, ichneumonoidea, braconidae) del pirineo andorrano

Phenology of the Braconidae (Hymenoptera, Ichneumonoidea) at Andorra has been conducted/studied using a Malaise trap after a one-year cycle during 1993.

The annual phenology has been characterized through the correlation between the evolution of the collected braconids and the weather (meteorological conditions). The maximum of the populations were registered between the two rain periods. In fact, the family Braconidae shows an abundance peak from middle of May to end of August, due to the xerothermic conditi…
