Chlorophorus robustior Pic, 1900 (Coleoptera: Cerambycidae) is a new record for the Turkish fauna and a new sainfoin (Onobrychis sativa Lam.) pest for Turkey. Its biology, damage, and infestation ratio were studied in Erzurum (Turkey) during 1996 and 1997. The biological stages of the pest are briefly described. The pest overwinters within galleries in roots of sainfoin as mature larvae. Pupation in the galleries begins in mid-May. At the end of June, the adults appear. The females lay their eggs individually into the stem base 7-10 days after emerging. The first larva begins to construct a gallery in the root. Each gallery has one larva, and each plant has one gallery. The last instar larva overwinters in the same gallery toward mid-September. Consequently, C. robustior produces one generation a year. Infestation level may reach up to 14-16%.
