| Abstract | ||
| The Mediterranean flour moth, Ephestia kuehniella (Lepidoptera: Pyrallidae) is one of the most destructive pests of flour, grains, baked goods and cereal products. The morphology of the larval antennae and mouthparts is described and illustrated with the aid of scanning electron microscopy, with particular focus on the sensilla. The antennae possess three types of sensilla: two sensilla chaetica, six sensilla basiconica, and a sensillum styloconicum. The labrum bears six pairs of sensilla chaetica. Each dentate mandible carries two sensilla chaetica on outer surface and five teeth.On the maxilla, both cardo and stipes carry one sensillum chaeticum. Each galea has three short-sharp sensilla basiconica, two large sensilla styloconica and three sensilla chaetica. The distal segment of the maxillary palp possesses seven sensilla basiconica, and one sensillun styloconicum. Each labial palp bears distally a cone-shaped sensillum chaeticum and an elongate sensillum styloconicum. In addition, the functions of these sensilla are discussed by comparing them with those of other Lepidopteran larvae. | ||
