Core Viewpoint - The article discusses the issue of invasive species in Guangdong Province, highlighting their ecological impact and the need for effective control measures [4][39]. Invasive Species Overview - Guangdong is one of the regions in China with the highest number of invasive species, with hundreds identified that threaten local ecosystems and agricultural safety [4][5]. - Invasive species can damage crops, outcompete native plants, and disrupt ecological balance due to the absence of natural predators [5][6]. Specific Invasive Species 1. Pomacea canaliculata (Golden Apple Snail) - Originally from the Amazon basin, this species was introduced to China in the 1980s and has rapidly spread in Guangdong's rice fields [10][11]. - It has a high feeding rate, consuming up to 40% of its body weight daily, primarily targeting young rice seedlings and vegetables, which severely affects crop emergence rates [12]. - The reproductive capacity is significant, with each snail capable of laying 200-1000 eggs multiple times a year, making control efforts challenging [13][15]. 2. Mikania micrantha (Mile-a-Minute Vine) - This perennial vine, native to Central America, has spread widely in Guangdong, particularly in forested areas and orchards [20][21]. - It grows rapidly, extending over 20 cm per day, and can smother native plants, leading to their death and causing severe ecological damage [22][24]. 3. Bidens pilosa (Spanish Needle) - Originally from tropical America, this species is now common in Guangdong's farmland and wastelands [29][30]. - It has strong adaptability and prolific reproduction, competing with crops for light, water, and nutrients, which can hinder agricultural productivity [31][32]. Control Measures - The article emphasizes the importance of public participation in controlling invasive species and provides specific strategies for managing the highlighted species [37][39]. - For Pomacea canaliculata, methods include manual collection and the use of specific pesticides while adhering to safety regulations [18][16]. - For Mikania micrantha, mechanical removal and targeted herbicide application are recommended to prevent its spread [26][28]. - For Bidens pilosa, early removal before flowering and the use of selective herbicides are suggested to minimize its impact on crops [34][36].
