A survey of parasitoid species within Eriogyna pyretorum (Lepidoptera: Saturniidae) in Fuzhou Region of China

Eriogyna pyretorum Westwood is a notorious defoliator of Cinnamomum camphora (L.) J. Presl that causes large economic and ecological losses in planted forests. To understand the importance of suppress population of E. pyretorum on natural parasitoids, a two-years investigation was conducted in the field. Four parasitoid species were identified from E. pyretorum Gregopimpla himalayensi s (Cameron, 1899), Theronia depressa (Gupta, 1962), Xanthopimpla konowi (Krieger, 1899) and Kriechbaumerella longiscutellaris Qian et He. G. himalayensi s and T. depressa were first reported parasitoid wasps within E. pyretorum . Parasitism rates were 18.76% for K. longiscutellaris , 2.10% for G. himalayensi s , 7.55% for T. depressa and 0.83% for X. konowi . Longevity, offspring and sex ratio were compared in four hymenopteran species, and K. longiscutellaris was the abundant parasitoid of E. pyretorum in Fujian province of China.
