Abstract
Since 2018, increased infestation by the fall armyworm Spodoptera frugiperda (FAW), an invasive pest worldwide, has negatively affected Asian crop production. Seasonal migratory activities drive regional outbreaks of this pest, but it remains unclear whether there is direct transboundary movement between East Asian and South Asian regions. From 2019 to 2023, FAW moth movements were monitored in Ruili of Yunnan Province, a city at the border area of China and Myanmar which is located in the insect migratory route between China and South Asian countries such as India and Bangladesh. The results showed that there was regular seasonal migratory activity of the pest, which could be divided into spring–summer (April–June) and autumn (October) peak migration periods. Further analysis using trajectory simulation model indicated that the FAW moths in spring–summer migration mostly come from Myanmar, the northeastern states of India and Bangladesh, and returns to the three countries in autumn from Southwest China. Our study clarifies the regional migration pattern of the FAW moth in China and South-Southeast Asia, providing a theoretical basis for constructing a regional early warning and management systems of this pest.
期刊介绍:
Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues.
Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates.
Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management.
Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
