Genetic Record for a Recent Invasion of Phenacoccus solenopsis (Hemiptera: Pseudococcidae) in Asia

First Report of the Papaya Mealybug,Paracoccus marginatus(Hemiptera: Pseudococcidae), in China and Genetic Record for Its Recent Invasion in Asia and Africa

“…Similar cases have been found with other invasive Sternorrhyncha. A single haplotype of the cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) has undergone a very recent rapid invasion in China (Ahmed et al 2015), and a single haplotype of an invasive whitefly has established a global distribution (De Barro & Ahmed 2011).…”

Invasion biology of the cotton mealybug, Phenacoccus solenopsis Tinsley: Current knowledge and future directions

“…Genetic variation and diversity of P. solenopsis Based on studies of other invasive insects (Tsutsui et al 2000;Johnson and Starks 2004;Grapputo et al 2005;Yang et al 2012;Piiroinen et al 2013;Kononov et al 2016), we predict that the genetic diversity of P. solenopsis is being influenced by a number of factors, such as pre-invasion history, the number/origin of introductions, transportation, demographic events (e.g., population bottlenecks and founder events), selection, gene mutation rate, and recombination. Few of these factors have been explored, although some researchers have addressed the genetic diversity of this mealybug (Thomas and Ramamurthy 2014;Ahmed et al 2015;Li et al 2015;Wu et al 2015). Future studies will provide insights into the evolutionary process of this mealybug and its contribution to invasion success.…”

“…值得关注的是, Beltrà 等 人 [68] [70] 以及陈哲等 人 [71] 的研究发现, 扶桑绵粉蚧存在 2 个进化支系, 入 侵我国的扶桑绵粉蚧仅为其中的一个谱系. Zhao 等 人 [72] 、Ahmed 等人 [73] 和 Wu 等人 [74] 对我国其他地区 和国外部分种群的分析验证了先前的推测, 并表明 我国不同地理种群的扶桑绵粉蚧其遗传差异较小; 中国、印度、巴基斯坦和美国加州的种群构成一个支 系, 美国佛罗里达州的种群为另一支系. 此外, He 等 人 [75] 还探讨了菠萝洁粉蚧种群的遗传多样性, 发现 我国的菠萝洁粉蚧存在 3 种单倍型, 其中海南万宁种 群可能是其中的一个隐存谱系, 而大陆单倍型与菲 律宾种群相近; 推测我国 20 世纪初从东南亚大量引 进种植菠萝(Ananas comosus)可能无意使菠萝洁粉蚧 借机入侵大陆, 为入侵害虫菠萝洁粉蚧的溯源提供 了依据.…”
