Mouthpart structure and elemental composition of the mandibles in the coffee berry borer (Coleoptera: Curculionidae: Scolytinae)
The various parts of the mouth in the coffee berry borer, Hypothenemus hampei (Ferrari), have been visualized and identified using scanning electron m icroscopy. The labial and maxillary palpi are three jointed and connected by a membrane that allows for t elescoping. The maxillary palpi contain two types of sensilla (basiconic and campaniform) within an apic al cuticular depression in the third segment of the palpus. The sides of the third segment of the maxillary palpus exhibits rod-shaped depressions, known as sensilla digitiformia. Sev eral cuticular elements were detected in the mandibles, including Al, C, Ca, Cl, Mg, Na, O, P, and Zn. Zinc, a heavy metal, was only detected in the incisors and could provide abrasion resistance.
