A PRIMARY STUDY OF THE OCCURRENCE OF LIRIOMYZA SATIVAE(BLANCHARD) IN NANCHANG AREA

7 hymenopterous species have been confirmed by the present study as parasites of Liriomyza sativat in the Nanchang area. These parasites will also porasitize the pea leaf-miner, Phytomyza horticola,except Chrysonotomyia okazakii and Hemiptarsenus varicornis. All of them are larval or larval -pupal purasites and no egg parasite and no egg parasite and pupal parasite has been reared. Opius sp. Diglyphus isaea, Chrysocharis pentheus are the dominant species among the parasites of the Liriomyza sativae as well as the pea leaf-miner in Nanchang area, but there is no effective parasite complex to control Liriomyza sativae as pea leaf miner. The climate and foods are very appropriate to arise the number of Liriomyza sativae in May to Oseptember. According to the investigation in the field, the Liviomyza sativae and its plant of alternative host never find out in winter, in Nanchang area.
