Two new species of Quadrastichus Girault (Hymenoptera: Eulophidae): Parasitoids of the leafminers Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) and Liriomyza trifolii (Burgess) (Diptera: Agromyzidae)
Journal of Hymenoptera Research 13 (1), 108-119
Abstract: The parasitoids Quadrastichus citrella Reina and La Salle and Q. plaquoi Reina and La Salle (Hymenoptera: Eulophidae) are described. Quadrastichus citrella, native of South-East Asia, has been used as a biological control agent of the citrus leafminer Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) in several countries that the pest has recently invaded. Quadrastichus plaquoi, from India, is a parasitoid of Liriomyza trifolii (Burgess) (Diptera: Agromyzidae). Characters of these new species are discussed, as well as their relationship to other members of the "anysis group" of species. Distributional and biological details of these wasps are given.
