More specifically, we draw attention to the importance of temperature on the occurrence of outbreaks. This variable is a limiting factor for the development of insects. Environments with higher temperatures provide a greater rate of reproduction and speed of development, leading to the occurrence of population outbreaks. Among the main species of caterpillars associated with soybean cultivation are: Anticarsia gemmatallis, Chrysodeixis includens, Rachiplusia naked, helicoverpa spp., Chloridea virescens, Elasmopalpus lignosellus, Epinotia aporema, Omyodes indicata and the complex spodoptera (Spodoptera frugiperda, S. cosmioides, S. eridania e S. albula). Through Table 1 it is possible to verify the ideal temperature ranges and their respective approximate egg-adult cycles for each of these species. We highlight that these temperature ranges are considered ideal for the development of these species, but are not considered limiting, that is, they may occur at temperatures outside the indicated ranges.
