The root maggot Delia radicum is a major pest of cole crops and its main natural enemies are the predator and parasitoid rove beetles Aleochara bilineata, Aleochara bipustulata and the parasitoid wasp Trybliographa rapae.

The efficiency of the biological control strategies based on parasitoids, either as a release or a conservative measure, depends on the timely arrival or release of the parasitoids after colonization of the field by the pest.

Some organisms have low dispersal ability, as phytoparasitic nematodes in soils, reducing the probability to find a sexual partner genetically distant. The consequence is a high number of mating between siblings. Those consanguineous mating consanguineous mating could have consequences for the breakdown of plant resistances
