Abstract:Mortality response to a 30-min exposure to low temperature was studied for all sta!?es of the potato lea˜hop˜er, Emp.o˜sca fabae (Harris). The relationship between mortal˜ty an.d tem˜erature fit a lmear logistic regression model for each stage from egg to adult, mcluslve. This model satisfactorily described data for the egg, first and second in star, ˜nd adult female only after allowing for extra-binomial variation. For the first- and second star data, a model with common slope but different intercepts was used. A common curve described the mortality responses of instars three through five. Cold hardiness increased with dev˜lopment stage from egg through adult. Implications for predicting over wintering populahon and early migrant mortality are discussed.
