SUMMARY Development of the black vine weevil, Otiorrhynchus sulcatus , was investigated at constant temperatures from 9 to 27 o C. Pre‐adult development was completed in 200 and 130 days at 15 and 24 o C, respectively. Eggs and larvae developed at 27 o C, but no pupation took place at this temperature. The developmental threshold temperatures for eggs, larvae + pre‐pupae and pupae were 6, 2–6 and 12 o C, respectively. Reproductive maturation of females took place at temperatures from 12 to 27 o C, but only a few females became reproductive at 12 o C. Most females at 12 o C, like those at 9 o C, had a short maturation feed, but the ovaries did not develop. The pre‐oviposition period was temperature dependent. The females showed a cyclic oviposition pattern with three peaks. The significance of soil temperatures for the phenology and distribution of O. sulcatus in Norway is discussed.
