Abstract: Frankliniella intonsa (Thysanoptera: Thripidae) is a polyphagous pest that causes significant economic agricultural losses by damaging flowers, vegetables, and fruit trees. We performed an age-stage two-sex life table analysis to evaluate the performance and adaptability of F. intonsa against nine common vegetable crops cultivated in Guangxi: cowpea ( Vigna unguiculata ) (Fabales: Leguminosae), green beans ( Phaseolus vulgaris ) (Fabales: Leguminosae), soybean ( Glycine max ) (Fabales: Leguminosae), catjang cowpea ( Vigna cylindrica ) (Fabales: Leguminosae), courgette ( Cucurbita pepo ) (Cucurbitales: Cucurbitaceae), wax gourd ( Benincasa hispida ) (Cucurbitales: Cucurbitaceae), bitter gourd ( Momordica charantia ) (Cucurbitales: Cucurbitaceae), cucumber ( Cucumis sativus ) (Cucurbitales: Cucurbitaceae), and chieh-qua ( Benincasa hispida ) (Cucurbitales: Cucurbitaceae). Among the tested host crops, green beans, cowpea, and courgette significantly accelerated the growth rate and favored the reproductive success of F. intonsa . Green beans, cowpea, and courgette facilitated rapid growth and reproductive success. The mean generation times (T) and net reproductive rates ( R 0 ) were as follows: 14.90 d, 17.09 d, 21.03 d, and 104.04, 45.51, 32.61. Bitter gourd and chieh-qua significantly suppressed population growth (T: 49.49 d, 0 d; R 0 : 0.73, 0). Wax gourd, catjang cowpea, cucumber, and soybean exhibited moderate effects characterized by delayed development and lower reproductive output (T: 22.30 d, 20.30 d, 19.51 d, 32.73 d; R 0 : 7.17, 25.22, 13.74, and 12.54). These findings highlight the critical role of crop type in F. intonsa population dynamics. Therefore, the agricultural production of green beans, cowpea, and courgette crops necessitates improved control measures and monitoring. Similar measures are needed for cucumber, catjang cowpea, soybeans, and wax gourds because they pose risks as potential hosts.
