The effect that the shifting of the host plant has on the fitness of a polyphagous pest is critical to its prevalence and potential pest control. In order to assess the fitness changes of P. marginatus after transferal from potato (Solanum tuberosum (Tubiflorae: Solanaceae)) to papaya (Carica papaya (Parietales: Caricacea)), sweet potato (Ipomoea batatas (Tubiflorae: Convolvulaceae)), and alligator weed (Alternanthera philoxeroides (Centrospermae: Amaranthaceae)), the life table data of three consecutive generations were collected and analyzed using the age-stage, two-sex life table method. The results showed that when P. marginatus was transferred from S. tuberosum to papaya, a higher intrinsic rate of increase (r) and finite rate of increase (\u03bb) were observed. Paracoccus marginatus individuals transferred to I. batatas had the significantly lower population parameters than those on C. papaya; however, the fitness recovered for those on I. batatas after two generations. Paracoccus marginatus individuals were unable to complete development on A. philoxeroides. Our results conclusively demonstrate that P. marginatus individuals can readily adapt to C. papaya and I. batatas even after host plant shifting, and are capable of causing severe damage to these hosts.<\/jats:p>","DOI":"10.3390\/insects13090804","type":"journal-article","created":{"date-parts":[[2022,9,6]],"date-time":"2022-09-06T05:17:23Z","timestamp":1662441443000},"page":"804","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Fitness of the Papaya Mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae), after Transferring from Solanum tuberosum to Carica papaya, Ipomoea batatas, and Alternanthera philoxeroides"],"prefix":"10.3390","volume":"13","author":[{"given":"Hui-Yu","family":"Chuai","sequence":"first","affiliation":[{"name":"Institute of Quality Standards & Testing Technology for Agro-Products\/Fujian Provincial Key Laboratory of Quality and Safety of Agricultural Products, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0628-2921","authenticated-orcid":false,"given":"Meng-Zhu","family":"Shi","sequence":"additional","affiliation":[{"name":"Institute of Quality Standards & Testing Technology for Agro-Products\/Fujian Provincial Key Laboratory of Quality and Safety of Agricultural Products, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6525-8251","authenticated-orcid":false,"given":"Jian-Yu","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1037-7867","authenticated-orcid":false,"given":"Li-Zhen","family":"Zheng","sequence":"additional","affiliation":[{"name":"Institute of Plant Protection, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian-Wei","family":"Fu","sequence":"additional","affiliation":[{"name":"Institute of Quality Standards & Testing Technology for Agro-Products\/Fujian Provincial Key Laboratory of Quality and Safety of Agricultural Products, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"},{"name":"College of Plant Protection, Fujian Agriculture and Forestry University, Fuzhou 350002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1469","DOI":"10.1653\/024.097.0422","article-title":"Morphological and molecular identification of Paracoccus marginatus (Hemiptera: Pseudococcidae) in Yunnan, China","volume":"97","author":"Wu","year":"2014","journal-title":"Fla.
