| Abstract:
The leaf-gall midge Procontarinia matteiana is a serious pest of mango in Oman. A survey of the infested areas in 1983 showed that the pest was free from natural enemies. Investigations in India, where the midge is one of several native pests of mango, have led to the discovery of a complex of hymenopterous parasites of P. matteiana and allied species. The parasites include Chrysonotomyia pulcherrima, two apparently undescribed Chrysonotomyia spp., two Tetrastichus spp. (Eulophidae), Synopeas procon, Inostemma oculare, Trichacoides indicus (Platygastridae), Ormyrus spp. (Ormyridae), Eupelmus sp. nr. testaceiventris (Eupelmidae), Gastrancistrus sp. (Pteromalidae) and Aphanogmus sp. (Ceraphronidae). Brief notes on the biology and economic status of the pest and on the distribution and relative abundance of the parasites are given. Chemical control measures have not given satisfactory results and have other limitations. Therefore, attempts at biological control of the midge in Oman are under way by introducing promising parasites from India. Species so far released in Oman are Chrysonotomyia pulcherrima, C. sp. near pulcherrima, E. sp. near testaceiventris, I. ocularc and Ormyrus sp. | |
