''Aulacophora'' is a genus of beetles in the family Chrysomelidae, commonly known as pumpkin beetles; some species are pests of agricultural crops. The genus was named in 1836 by the French entomologist Louis Alexandre Auguste Chevrolat, in Pierre François Marie Auguste Dejean, Dejean's ''Catalogue des Coléoptères''. The name, from Ancient Greek, signifies "furrow-bearer"' from ''aulax'', "furrow". Description Beetles in this genus are oval insects up to about long and can be recognised by their presence on the Host (biology), host plant. Distribution Pumpkin beetles are found in Africa, Asia and Australasia. Some of the more important pest species are ''Aulacophora foveicollis, A. foveicollis'' from Africa, Europe and Asia, ''Aulacophora similis, A. similis'' from southern and southeastern Asia, ''Aulacophora coffeae, A. coffeae'' from Malaysia, ''Aulacophora flavomarginata, A. flavomarginata'' from Malaysia and Indonesia, ''Aulacophora femoralis, A. femoralis'' from Myanmar ...

Description The beetle is relatively small with a hard, black exoskeleton containing faint yellowish dots around the sides. The head is a deep, bright orange, while ''A. nigripennis'' has a large orange compartmentalized thorax. Feeding A. nigripennis is a pest that feeds off of the 28 species in the '' Dianthus'' and '' Tricosantes'' genera of plants by creating a circular "trench" using its mandibles. After circularly cutting through the leaf, the trench overflows with sticky phloem sap that, through cohesion, sticks to form a semicircle around the beetle. The beetle then sucks the sap using its mouth. Pest control Researchers at the Journal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
