Abstract

  Occurrence of Liriomyza trifolii and its biological control efficacy using Neochrysocharis formosa were evaluated in two eggplant cropping systems of spring and autumn cultivation. L. trifolii adults began to be attracted on a yellow sticky traps from late April and they increased from early June. A high density of L. trifolii adults was maintained from middle June to middle July. The releases of two N. formosa per plant with 3 times as weekly intervals from May 25, 2004 for spring culture resulted control effect of 90.1% in parasitism to L. trifolii in late July. The releases of two N. formosa per plant with 4 times as weekly intervals from Auguest 31, 2004 for autumn culture resulted control effect of 81.3% in population of L. trifolii with 64.4-69.9% in parasitism.
