Eriogyna pyretorum Westwood is a notorious defoliator of Camphora officinarum Nees that causes large economic and ecological losses in planted forests.To understand the importance of suppressing the population of E.pyretorum on natural parasitoids, a four-years investigation was conducted in the field.Four egg parasitoid species Ooencyrtus kuvanae Howard, Trichogramma chionis Ishii, Telenomus sp.

and Anastatus dexingensis Sheng & Wang were captured in the wild.One of these is the dominant endoparasitoid species Cage T.chionis, which has a quicker developmental time (8.33 d), more offspring (8.

39/egg) ECINACEA LOZ and a greater parasitism rate (89.54%).With different elevation distributions, the parasitism rates for Kriechbaumerella longiscutellaris Qian & He, Gregopimpla himalayensis (Cameron), Theronia depressa (Gupta) and Xanthopimpla konowi (Krieger) were 17.29%, 2.

10%, 4.23% and 0.83%, respectively.Female longevity (47.

75 d), offspring (13.36/pupa) and sex ratio (1.16:1) were compared in four pupal parasitoids and K.longiscutellaris was the most abundant species of E.

pyretorum in Fujian Province.
