The range of the beet webworm Loxostege sticticalis L. (Lepidoptera, Pyraloidea: Crambidae) in the former USSR territory and its subdivision by the number of generations per season
Entomological Review 94 (2), 200-204
Abstract: The distribution limits of the beet webworm, Loxostege sticticalis L., with its sustainable development in one, two, three, or four successive generations per season in the former USSR territory were mapped for the first time using routine GIS procedures. The expected number of generations was determined based on the sum of daydegrees (above a threshold of 12°C), critical day length value (14 h), and Selyaninov's hydrothermal index (> 0.3). The compiled map was in good agreement with that prepared for China (Luo Li-zhi and Li Guang-bo, 1993).
