概要 The vegetable leafminer Liriomyza sativae has been well established on many vegetable crops in Vietnam, but have never invested the leafminer relative abundance and its associated parasitoids. A surve...y was conducted in three locations of the Hochiminh region of Vietnam during the rainy and dry season (July2003-Janary 2004) with arm at recording associated parasitoid species complex and relative abundance of the leafminer and its parasitoids on the cucumber fields. Infestations of L. sativae occured in the field during the rainy season with low densities and became more serious in the dry season. Sampling of leadminer-infested leaves from cucumber plants yielded 7 species of hymenopteran parasitoids. The most abundant species were Neochrysocharis sp. and Asecodes delucchii, accounting for 43.7-69.6% and 18.5-46% parasitism, respectively. The pest population was low when parasitism was high in all foelds sampled. The results suggest that these parasitoids play a very important role in L sativae suppression in the cultivated cucumber fields.続きを見る
