Los áfidos representan una problemática para muchas especies de plantas, debido a que son vectores de múltiples patógenos; el control biológico mediante el uso de parasitoides es una opción permanente de control de sus poblaciones.

Biodiversity of hymenopteran parasitoids
Parasitoid wasps are the most successful group of insect parasitoids, comprising more than half the known diversity of Hymenoptera and probably most of the unknown diversity. This lifestyle has enabled them to be used as pest control agents conferring substantial economic benefits to global agriculture.

We quantified the geographical overlap between parasitoid wasps and their known host spiders. We could assess which parasitoid species have more limited information about their interactions and are subject to geographical survey bias. We generated sampling bias maps to assist other researchers in identifying where the main sampling gaps are.

In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

Descortezadores y sus enemigos naturales en Abies religiosa (Kunth) Schltdl. et Cham.
El Parque Nacional “Lagunas de Zempoala” es un área natural protegida que se ubica en los límites de los estados Morelos y el Estado de México, en donde se eligió un oyamel sobramaduro de 20 m de alto para estudiar la distribución de insectos ...

Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

An exotic parasitoid provides an invasional lifeline for native parasitoids
AbstractThe introduction of an exotic species may alter food webs within the ecosystem and significantly affect the biodiversity of indigenous species at different trophic levels. It has been postulated that recent introduction of the brown marmorated stinkbug (Halyomorpha halys (Stål)) represents an evolutionary trap for native parasitoids, as they ...
