Overview of the Fig Whitefly and Its Hosts

The fig whitefly, scientifically known as *Siphoninus phillyreae*, has emerged as a significant pest since its introduction to the United States, particularly affecting various species within the Ficus genus, with the weeping fig (*Ficus benjamina*) being the most commonly infested. Native to southeastern Asia, this pest was first detected in Florida in 2007 and later in California in 2012, spreading rapidly across Florida and impacting numerous Ficus species. Besides the weeping fig, it may also infest F. altissima, F. aurea, and other Ficus varieties, and occasionally affects azaleas. Its presence is widespread in urban landscapes, particularly in South Florida, where it poses substantial economic impacts due to defoliation and increased maintenance costs for affected ornamental trees. The importance of preserving natural enemies is emphasized to inform pest management strategies against this invasive species.

Identifying the Fig Whitefly Life Cycle

Identifying the life cycle of the fig whitefly, *Siphoninus phillyreae*, is crucial for effective management of this pest, as each stage plays a crucial role in its population dynamics. The life cycle typically lasts about 30 days under ideal temperatures of 25°C to 30°C. The process begins with eggs laid on the underside of leaves, hatching after approximately 11 days. Nymphs, which are initially mobile, remain immobile as they mature, feeding on the leaf for about 19-20 days. The pupal stage follows, lasting a shorter duration, during which the adult develops. Finally, adults emerge, reproduce quickly, and contribute to overlapping generations, which greatly impacts infestation levels. Understanding these stages helps in implementing effective control strategies, as the fig whitefly is a major pest that can cause significant damage to Ficus species.

Damage Caused by Fig Whitefly Infestations

When fig whiteflies infest plants, you’ll likely notice leaf yellowing and eventual drop, which signals a decline in plant health.
