Identification of the sex pheromone of Phyllophaga cuyabana (Coleoptera: Melolonthidae)

Feeding and oviposition preference of Phyllophaga cuyabana (Moser) (Coleoptera: Melolonthidae) on several crops.

Laboratory and greenhouse experiments were carried out to study food and oviposition preference by Phyllophaga cuyabana (Moser) on different plant species as Cajanus cajan L. (pigeon pea), Crotalaria juncea L. (sun hemp), Crotalaria spectabilis Roth (showy crotalaria), Crotalaria ochroleuca G. Don (slenderleaf rattlebox), Glycine max [L.] Merrill (soybean), Gossypium hirsutum L. (cotton), Helia...

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

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...

Identification of an important component of the contact sex pheromone of Callidiellum rufipenne (Coleoptera: Cerambycidae).

Adult male and female Callidiellum rufipenne (Motschulsky) (Coleoptera: Cerambycidae) aggregate on severely stressed or fallen trees and cut logs of cypress species (Cupressaceae) that are the hosts of their larvae. Our studies showed that male C. rufipenne actively search for females on these trees and only respond to females after contacting them with their antennae. Removing cuticular hydroc...
