Pryeria sinica Moore (Lepidoptera: Zygaenidae), an invasive pest of Euonymus, is susceptible in the second instar to the Bacillus thuringiensis Berliner product Thuricide®, and to several strains isolated from other B. thuringiensis products. Third instars are also susceptible, whereas susceptibility declines in the fourth (last) instar. The susceptibility of second-instar P. sinica to B. thuringiensis is comparable to that of second-instar gypsy moth, Lymantria dispar (L.), a pest commonly controlled with B. thuringiensis. Pryeria sinica, thus, should also be controllable with B. thuringiensis.
