Species Guides
1- Aleurochiton forbesii(Maple whitefly)
Aleurochiton is a of whiteflies (Aleyrodidae) primarily associated with maple trees (Acer ). The genus exhibits seasonal dimorphism, with distinct summer and winter puparial morphs linked to induction. Species within this genus are , producing rapid-developing summer and diapausing winter generations that require chilling to terminate dormancy.

Habitat
Associated with maple trees (Acer ), including Norway maple (Acer platanoides) and field maple (Acer campestre).
Distribution
Recorded from Denmark, Norway, Sweden, and Vermont, USA.
Seasonality
with summer active in July and winter generation developing from late summer; winter require spring chilling to emerge.
Diet
Phloem-feeding on maple trees.
Host Associations
- Acer platanoides - Norway maple; primary of Aleurochiton complanatus
- Acer campestre - field maple; of Aleurochiton acerina
Life Cycle
Seasonally dimorphic with distinct puparial types: delicate, pale summer that develop immediately, and heavily sclerotized, dark winter puparia with white wax patterns that enter true . Winter puparia require at least 1–2 months of chilling (0–8°C) for diapause termination; development is arrested at 20°C and strongly retarded at 15°C. Some individuals in each deviate from the typical pattern, with up to 10% winter puparia in the first generation and occasional summer puparia in the second generation.
