摘要

The spiraling whitefly, Aleurodicus dispersus Russell (Hemiptera: Aleyrodidae), is a highly polyphagous pest that poses a major threat to tropical and subtropical agriculture. Its rapid proliferation across multiple crop species is influenced by host plant quality, which significantly affects its development, reproduction, and survival. This study evaluated the influence of ten different host plants (cassava, cotton, guava, papaya, banana, mulberry, chilli (Capsicum annuum), Acalypha indica, eggplant, and Indian beech) on the developmental and reproductive parameters of A. dispersus under insect-proof screen house conditions. Developmental and reproductive traits varied significantly among host plants. The total developmental period (TDP) ranged from 24.2 ± 2.39 days on mulberry to 31.9 ± 3.35 days on banana (F = 6.06; df = 9, 90; P < 0.001). Egg hatchability and adult emergence were highest on cotton (98.7% and 98.2%, respectively) and lowest on Indian beech and eggplant. Fecundity was highest on cassava (28.5 ± 3.72 eggs per female) and lowest on eggplant (13.1 ± 1.79 eggs per female) (F = 27.20; df = 9, 90; P < 0.001). Female longevity was longest on cotton and cassava. A strong positive correlation was observed between egg hatchability and adult emergence (r = 0.85; P < 0.001), whereas a significant negative correlation was found between TDP and fecundity (r = − 0.78; P < 0.001). These results demonstrates host plant species significantly influence the biological performance of A. dispersus. Cassava, cotton, and guava supported comparatively faster development and higher reproductive output, indicating their suitability for population buildup. The findings provide useful insights for host-based pest management and highlight the potential role of less suitable host plants in reducing whitefly population growth within integrated pest management (IPM) programs.
