| Abstract:
The artichoke crop was established in Navarra a long time ago and logically, its pathogens were established in parallel. At the same time, natural enemies of those pathogens were taking up their place in ecosystems, keeping the parasite’s expansion in check. Among the enemies of artichoke crop, Gortyna xanthenes is highlighted as the main pest owing to its virulence. In almost all the artichoke fields, numerous natural enemies have been observed, being the most abundant in fields with more than one year of plantation. Though parasites of this pest are numerous and varied, in this paper we only refer to the hymenopteran Pseudovipio castrator. This artichoke enemy has one generation per year and its parasitic action starts in mid-May, when larva is more than 2 cm long and the damage is totally visible. The knowledge of its biology could minimize the use of harmful chemicals for increasing and extending the populations, and for biological control. | |
