Astegopteryx


Astegopteryx is a genus of aphids in the family Aphididae. The genus has an oriental distribution.

Life cycle and ecology

Some species of Astegopteryx have host alternation between their primary host plants, Styrax trees, on which they form multiple-cavity galls, and secondary host plants, mainly bamboos and palms. Individuals on primary and secondary hosts are morphologically very different and have been misclassified as representatives of different species and genera. "Soldier" morphs occur on both primary and secondary hosts. However, many species can live exclusively on their secondary hosts with parthenogenetic reproduction.
Some Astegopteryx are considered pest insects, e.g., Astegopteryx formosana and Astegopteryx formosana on bamboos and Astegopteryx rhapidis on oil palms.
