Sexual Dimorphism in Antennae of Mexican Species of Phyllophaga (Coleoptera: Scarabaeoidea: Melolonthidae)

Adult Phyllophaga Ephilida Host Plant Feeding Preference

Limited biological information about Phyllophaga ephilida , a major sweet potato pest in Louisiana, is available. In 2001 and 2002, a study was conducted in the laboratory to investigate the feeding preference of adult Phyllophaga ephilida (Say) (Coleoptera: Scarabaeidae) for the foliage of eight woody plant species: water oak ( Quercus nigra L.), live oak ( Quercus virginiana Mill.), red maple...

Sexual dimorphism in antennal receptors of Phyllophaga ravida Blanchard (Coleoptera: Scarabaeoidea: Melolonthidae).

The external morphology of sensilla on the antennae of males and females of Phyllophaga ravida Blanchard is described using scanning electron microscopy. Sexual dimorphism in body and antennal dimensions and in antennal receptor types was found. The female's body is slightly larger than the male's, although male antennal lamellae are longer than in females. Sixteen types of sensilla were identi...
