Abstract
This study investigates the biological characteristics and infestation
patterns of the cotton mealybug, Phenacoccus solenopsis Tinsley
(Hemiptera: Pseudococcidae), within the Chittorgarh district of Rajasthan,
India. Conducted between June 2024 and February 2025, the research highlights
the species' high prolificacy—capable of producing 12–15 generations per
year—and its adaptation to temperatures ranging from 10°C to 45°C. Host
Susceptibility: Field surveys of four distinct sites revealed a broad host
range, with the highest infestation rates found in Cotton (50%) and Hibiscus
(45%), followed by Papaya (30%) and Tomato (20%). Life Cycle & Morphology:
The study documented distinct sexual dimorphism; females undergo three nymphal
instars and are wingless, while males undergo four instars, including a pupal
stage, emerging as short-lived winged adults. Economic Impact: Damage is
primarily caused through the extraction of plant sap, leading to chlorosis,
stunting, and premature fruit drop. The excretion of honeydew further
exacerbates damage by fostering sooty mold and symbiotic relationships with
ants. The results underscore the status of P. solenopsis as a
significant invasive threat to both agricultural and horticultural stability in
southern Rajasthan, necessitating prioritized management strategies for its
primary hosts.
