“…The ability of S. frugiperda pupae to survive and develop at high temperatures in the soil, therefore, provides an advantage for this pest in terms of its development and survival. The estimated lower development threshold of 13.01 ± 0.10 • C for eggs is near the thresholds estimated by Ali et al [29] (12.69 ± 1.37 • C) and Hogg et al [37] (13.4 • C), but lower than the 16.95 ± 1.35 • C threshold reported by Barfield et al [38]. Busato et al [31] reported different lower development thresholds (9.3 and 8.1 • C) for eggs of the corn strain of S. frugiperda collected in two geographically different areas in Brazil, and 8.1 • C for eggs of the rice strain, regardless of the area sampled.…”

“…• C in the current study was faster than those reported by Busato et al [31], which were 41.9 days at 18 • C and 11.1 days at 32 • C. Larval mortality was the lowest between 26 and 30 • C, with 70% of larvae that died at 18 • C and 28% at 32 • C. Barfield et al [38] also reported S. frugiperda larval mortality to be higher at 18 and 37 • C than at 26.7 • C.…”

The fall armyworm (Spodoptera frugiperda) is a pest of tropical origin which recently invaded Africa, the Far East and Australia. Temperature, therefore, plays an important role in its invasion biology, since this pest does not go into diapause. The aim of this study was to determine the development rate of S. frugiperda at different temperatures and to calculate the number of degree-days (°D) required for each stage to complete its development. This study was conducted at five different temperatures—18, 22, 26, 30 and 32 ± 1 °C. Larvae were reared individually in Petri dishes with sweetcorn kernels provided as food. The development rate of S. frugiperda increased linearly with increasing temperatures between 18 and 30 °C and larval survival was the highest between 26 and 30 °C. The optimal range for egg, larval and egg-to-adult development was between 26 and 30 °C. The optimum temperature with the fastest larval development rate and lowest mortality was at 30 °C. The pupal development period ranged between 7.82 and 30.68 days (32–18 °C). The minimum temperature threshold for egg and larva development was 13.01 and 12.12 °C, respectively, 13.06 °C for pupae and 12.57 °C for egg-to-adult development. Degree-day requirements for the development of the respective life cycle stages of S. frugiperda were 35.68 ± 0.22 for eggs, 204.60 ± 1.23 °D for larvae, 150.54 ± 0.93 °D for pupae and 391.61 ± 1.42 °D for egg-to-adult development.

“…When winter temperatures fall below the tolerance level of the overwintering stage of an insect, it cannot survive. Note that in the United States, the fall armyworm (Spodoptera frugiperda), which is a species of tropical origin, is able to overwinter only in the southern parts of Texas and Florida (Luginbill 1928;Barfield et al 1978). In spring, this pest advances northward by flight, each generation spreading farther north.…”

PIMENTEL, D. 1994. Insect population responses to environmental stress and pollutants. Environ. Rev. 2: 1-15.Insects and other related arthropods make up about 90% of all plant and animal species in the world. They are vital to the functioning of the ecosystem and biosphere, and neither of these systems can operate effectively without insect interactions. Because of their major ecological and economic roles in nature and society, the beneficial and pest activities of insects need to be clearly understood. Insect populations are being stressed directly by the action of temperature, moisture, and a wide array of chemical pollutants (pesticides, fertilizers, air pollutants, and numerous other chemicals) that are dispersed through air, water, and soil. Insects are affected by this same group of stresses indirectly, through their food plants, parasites, and predators. Depending on the species and the particular stress affecting it, insect populations respond by increasing or decreasing in numbers. The responses of insect populations to various direct and indirect environmental stresses and chemical pollutants are assessed. Some insect populations increase, while others decline. The responses were determined by the particular environmental stress, the insect species, and the stage at which they were exposed to the stress.
