Anoplophora glabripennis (Motschulsky) (Coleoptera: Cerambycidae) is a recently introduced non-native invasive species in North America that has the potential to destroy several tree species in urban and forest habitats. Adult survival, reproduction, and egg hatch of A. glabripennis from two populations (Ravenswood, Chicago, IL, and Bayside, Queens, NY) were evaluated at seven constant temperatures (5, 10, 15, 20, 25, 30, and 35 degrees C), and adult survival was evaluated at -1 degrees C. Nonlinear regressions were used to estimate the temperature optimum and thresholds for each life history parameter. The estimated optimum temperature for median longevity was 18 degrees C, and upper and lower thresholds were 39 and -3 degrees C for females and 38 and -2 degrees C for males. The estimated upper and lower thresholds for fecundity were 35 and 11 degrees C for the New York population and 34 and 14 degrees C for the Illinois population. The estimated optimum temperature for maximum fecundity was 23 and 24 degrees C for the New York and Illinois populations, respectively. Both longevity and fecundity declined as temperature increased or decreased from the optimum. Oviposition was arrested at temperatures <= 10 and >= 35 degrees C, and either eggs did not mature or were reabsorbed by females that did not oviposit at the higher temperatures. Days to first oviposition approached infinity near 10 degrees C and declined exponentially to a minimum of 16 d at 30 degrees C. The lower threshold for egg hatch was estimated as 10 degrees C and the upper threshold at 32 degrees C, and eggs would be predicted to hatch the fastest at 29 degrees C. Maximum percentage hatch was estimated to occur at 23 degrees C, and the estimated upper and lower thresholds were 34 and 12 degrees C, respectively. These results indicate that summer temperatures throughout most of the lower 48 United States should support beetle survival and reproduction, although oviposition may be suspended and adult survivorship would decline when day or more at or above 30 degrees C, and there are no cooler addition, although beetles may survive into the fall, and those eggs may not hatch until spring. These res used for predicting the potential geographical range models to predict the timing of egg hatch and adult programs.
