The survival, developmental time, and reproductive rates ofAmphorophora agathonicaHottes were measured in the laboratory on 4 red raspberry cultivars. Mortality was greatest on Canby>Malling Exploit>Washington>Latham (susceptible). It occurred primarily in the 1st and 2nd instars on Canby and Malling Exploit, but was distributed throughout all instars on Washington. Development was slow on Canby and Washington, while developmental time on Malling Exploit was comparable to the susceptible Latham. Fecundity was lowest on Canby
