The length of the egg and larval development of Coreus marginatus (Linnaeus, 1758) was investigated at constant temperatures of 19.2 oC, 21.0 oC, 25.0 oC and 27.8 oC. For egg development, the lower developmental threshold (LDT) temperature was estimated to be 12.9 oC and sum of effective temperatures (SET) 142.9 day degrees (dd). The larvae were fed seeds of Rumex obtusifolius L. The mortality increased with decreasing temperature. Using data for the first three larval instars, where mortality was low, LDT was calculated to be 13.9 oC. No larvae completed development at 19.2 oC and few at 21.0 oC and 25.0 oC. At 27.8 oC 75 % of the larvae completed their larval development. Using the data on developmental length at this temperature the SET for larval development was estimated to be 556 dd and SET for complete pre-imaginal development (egg + larva) 742 dd. The long developmental time and high larval mortality indicated that a diet consisting only of R. obtusifolius seeds was unsuitable for the development of Coreus marginatus. ER -
