Whiteflies
Guides
Aleurodicinae
whiteflies
Aleurodicinae is a subfamily of whiteflies (Aleyrodidae: Hemiptera) distinguished by morphological features of the pupal case, including the arrangement of setae and pore structures. The subfamily contains over 40 species in Belize alone, with substantial diversity throughout the Neotropical region. Members are phloem-feeders on vascular plants, with some species established as invasive pests in introduced ranges including the western Palaearctic, Pacific, Southeast Asia, and Canary Islands. At least one genus secretes distinctive blue-iridescent wax.
Aleyrodinae
whiteflies
Aleyrodinae is the largest subfamily of whiteflies (Hemiptera: Aleyrodidae), containing the majority of described species. Members are small, sap-sucking insects with powdery white wax-coated wings in adults. 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.
Aleyrodoidea
whiteflies
Aleyrodoidea is a superfamily of small hemipteran insects commonly known as whiteflies. The superfamily contains a single family, Aleyrodidae, with more than 1,550 described species. Whiteflies are phytophagous insects that feed on plant sap, typically from the undersides of leaves. Several species are significant agricultural pests, including the citrus blackfly (Aleurocanthus woglumi) and the Bemisia tabaci species complex.
Azotidae
Azotidae is a small family of chalcidoid wasps containing a single genus, Ablerus Howard, 1894, with approximately 92–94 described species. The family was elevated from subfamily status within Aphelinidae in 1966 and is now recognized as a distinct family in Chalcidoidea. Azotidae are obligate hyperparasitoids that attack primary parasitoids of hemipteran pests, particularly those associated with scale insects (Diaspididae), whiteflies (Aleyrodidae), and mealybugs. Their biology makes them significant tertiary consumers in agricultural food webs.
Orius vicinus
minute pirate bug
Orius vicinus is a predatory minute pirate bug (Hemiptera: Anthocoridae) studied extensively for biological control potential. Under laboratory conditions at 26°C, it completes development from egg to adult in approximately 18–23 days, with females living 15–17 days and producing 31–61 eggs. The species exhibits Type II or Type III functional responses depending on prey stage, with adult prey generally preferred over eggs. It has been observed feeding on spider mites, whiteflies, thrips, and other small arthropods in agricultural settings. Unlike some congeners, O. vicinus does not enter reproductive diapause and continues oviposition through winter conditions.
