Chinese oak silkworm ( Antheraea pernyi ) and mulberry silkworm ( Bombyx mori ) are economically important insects used for silk production and food resource. Entomopathogenic nematodes (EPNs) from the families of Steinernematidae and Heterorhabditidae are beneficial organisms currently considered in biological control. In this paper, we evaluated survival of two silkworm species exposed to four Steinernema species which are widely applied in pest control. The results showed that among four Steinernema species, S. bicornutum and S. feltiae did not have an effect on the larval survival to the two silkworm species, whereas S. carpocapsae and S. glaseri did have an effect. Each Steinernema species poses no threat to hatchability of eggs, pupation rate, larval durations and cocoon shell ratio.
