Egg parasitoids of economic significance are found in the families Trichogrammatidae, Mymaridae, Scelionidae and Platygastridae. Research on egg parasitoids other than Trichogramma has increased at a slower level during the last 15 years. For instance, the last International Organization of Biological Control review on egg parasitoids summarizing references from 1997 to 2003 listed 77 references on Trichogrammatidae, 50 on Mymaridae, 72 on Scelionidae and none on Platygastridae (Table 13.1). Within the Trichogrammatidae, 94% of these references are on the genus Trichogramma, 1% on the genus BrachyufensBrachyufens and 5% on the genus UscanaUscana and none on HaeckelianiaHaeckeliania (Herz et al. 2003). Moreover, from the late 60s through mid 2004, Agricola (2003) cites a total of 219 publications on the Trichogrammatidae; of these, 86% are references on the genus Trichogramma, 0.4% on Brachyufens, 0.4% on ChaetogrammaChaetogramma Doutt, 8% on OligositaOligosita , 3.6% on MegaphragmaMegaphragma , 0.8% on UfensUfens , 0.8% on ZagellaZagella and none on Haeckeliania (Table 13.2). The major objective of this chapter is to discuss biological control of root weevils affecting primarily citrus and biological control of cicadellids affecting grape with egg parasitoids other than Trichogramma.
