Abstract
The interaction between plant viruses and insect vectors influences
pest dynamics, yet effects on vector fitness remain unclear. This study
assessed direct and plant-mediated effects of Tomato leaf curl Palampur virus
(ToLCPMV) on fecundity and development of Bemisia tabaci across seasons
using tomato (susceptible host) and cotton (non-host). On tomato, fecundity
varied with virus status, plant condition, and season; viruliferous whiteflies
laid more eggs, peaking on healthy plants during SMW 37 (129.80 ± 5.36 eggs),
while the lowest occurred in non-viruliferous individuals on infected plants in
SMW 51 (16.00 ± 1.22 eggs). Oviposition followed similar trends (4.99 ± 0.25
eggs/female/cm²/day, SMW 37). Developmental durations were primarily
temperature-driven, extending under cooler conditions. Female longevity
increased in viruliferous individuals. On cotton, viruliferous whiteflies again
showed higher fecundity (128.40 ± 2.97 eggs, SMW 28). Temperature and sunshine
enhanced fecundity, whereas humidity and rainfall prolonged development, with
initial attraction to infected plants shifting later to healthy hosts.
