Introduction
Leafmining insects are dangerous pests that reduce plant metabolic activities and can lead to desiccation and premature fall of the leaves. If leaves are seriously attacked, crops can be reduced or seedling plants even totally destroyed (Spencer, 1990). The leafmining habit is found in several Lepidoptera and Diptera species, and also in some Coleoptera and Hymenoptera. Among these, the Agromyzidae (Diptera) is known primarily as a family of leafminers, as the majority (75%) of the almost 2000 known species display this biology. They are pests of economic relevance of numerous vegetables and floricultural crops in all the regions of the world. Several of these species are particularly capable of causing extensive economic damage to a large range of host plants under both field and greenhouse conditions (Spencer, 1973; 1990).
Biological control is a preferred option for control for these serpentine leafminers (Minkenberg & van Lenteren, 1986; Waterhouse & Norris, 1987; Johnson, 1993), as chemical control measures have in many cases been ineffective. This has been due to indiscriminate use of insecticides, their negative impact on natural enemies, and the development of resistance (Rauf & Shepard, 1999; Murphy & La Salle, 1999). Sustainable control of agromyzids could include conservation or enhancement of local natural enemies and/or the introduction of appropriate natural enemies from the area of origin of the pest or from related leafminers from other areas. However, these strategies are not mutually exclusive, as it is clear that any introductions should take into account the existing local natural enemy community. Although there is a rich and diverse fauna of leafminer parasitoids, many of these are generalists and care must be taken in deciding whether or not to introduce exotic natural enemies. Murphy & La Salle (1999) recommended that, due to the prevalence and often general nature of leafminer parasitoids, effort should be put into understanding and conserving indigenous leafminer parasitoids rather than relying solely on the introduction of exotic parasitoids.
Investigations on the natural enemy communities of leafminers have shown that there is generally a large number of natural enemies, in particular numerous Hymenoptera parasitoids belonging to the families Eulophidae and Pteromalidae (Chalcidoidea), Braconidae (Ichneumonoidea) and Eucoilidae (Cynipoidea).
