Summary

New Zealand Thrips obscuratus adults were exposed to combinations of temperature (0, 7, 13 or 20 deg C), air (0, 9 or 18% carbon dioxide in 2% oxygen, with the balance nitrogen), and exposure time (2, 4, 6 or 8 days). Mortality varied directly with temperature, gas and time. Two-way interactions between temperature and gas, temperature and time, and gas and time were significant. It is discussed how mortality-response surfaces can be used to help develop integrated, controlled-atmosphere programs that are both effective against the pest and sensitive to the physiological tolerance of the produce.
