Sensitivity of the Larvae of Two Tea Tortricids in Southern Kyushu, Adoxophyes dubia and Adoxophyes honmai (Lepidoptera: Tortricidae), to Adoxophyes orana Granulovirus

Abstract

The sensitivity of the larvae of two tea tortricids, Adoxophyes dubia and A. honmai, to Adoxophyes orana granulovirus was compared by peroral inoculation of granular inclusion bodies. A. dubia and A. honmai used in this study originated from feral moths collected in southern Kyushu, and were maintained as laboratory stocks. Although the larvae of the two species showed similar sensitivity to A. orana granulovirus during early to middle larval stages, extension of the larval period caused by the granulovirus was more evident in A. dubia than in A. honmai.
