Aleyrodinae

Westwood, 1840

whiteflies

Genus Guides

Aleyrodinae is the largest of whiteflies (Hemiptera: Aleyrodidae), containing the majority of described . Members are small, sap-sucking insects with powdery white wax-coated wings in . The subfamily includes economically significant agricultural pests such as Bemisia tabaci and Aleurotrachelus trachoides, which cause damage through direct feeding and virus transmission. A field survey in Belize recorded nearly 200 whitefly species, with all but 40 belonging to Aleyrodinae.

Life Cycle

Development includes and multiple nymphal instars. Fourth-instar nymphs are and manually sampled from leaf blades. Nymphs produce waxy secretions. The so-called 'pupal' case () is a taxonomically important stage with diagnostic morphological characters including marginal setae and lingula .

Behavior

Oviposition and survival are functions of leaf age, with distinct probing and oviposition observed between young and mature leaves. show seasonal fluctuation; dry winter periods promote increase while rainfall acts as a natural regulating agent influencing mortality. prefer high-temperature environments.

Ecological Role

Agricultural pests causing economic losses through direct feeding damage and as for plant virus transmission. Occupies both creeping plants and tree in forest environments. Subject to by native .

Human Relevance

Major agricultural pests requiring management in crop production systems. Bemisia tabaci has caused economic losses in Brazil since 1923. are intercepted at ports of entry on imported plant material, indicating biosecurity significance. Management challenges exist in both field and protected agricultural systems.
