Temperature-Dependent Life Table Parameters of Brown Marmorated Stink Bug, (Stål) (Hemiptera: Pentatomidae) in the United States.

Brown marmorated stink bug, (Stål) (Hemiptera: Pentatomidae), is a generalist pest that causes serious injury to a variety of crops around the world. After the first detection in the USA, became a serious threat to growers resulting in significant crop damage. Understanding the effect of temperature on development will help to achieve successful control by predicting the phenological timing of the pest. Here, life table parameters (survival, development, reproduction, and daily mortality) of were evaluated for New Jersey and Oregon populations in the US. Parameters were determined from field-collected and laboratory-reared individuals. The results indicated that New Jersey populations had higher levels of egg-laying than Oregon populations and exhibited higher and earlier fecundity peaks. Survival levels were similar between populations. Linear and nonlinear fit were used to estimate the minimum (14.3 °C), optimal (27.8 °C), and maximum (35.9 °C) temperatures where development of can take place. An age-specific fecundity peak (M = 36.63) was recorded at 936 degree days for New Jersey populations, while maximum fecundity (M = 11.85) occurred at 1145 degree days in Oregon. No oviposition was recorded at the lowest (15 °C) or highest (35 °C) trialed temperatures. Developmental periods increased at temperatures above 30 °C, indicating that such higher temperatures are suboptimal for development. Altogether the most optimal temperatures for population increase () ranged from 25 to 30 °C. Survival rates of at suboptimal low temperatures of 8 °C (i.e., 61%) is comparable to previous reports. The present paper provides additional data and context from a range of experimental conditions and populations. Such temperature-related life table parameters can be used to provide determine the risk to susceptible crops.
