Fine structure of selected mouthpart sensory organs of gypsy moth larvaeThis article is part of a larger document. View the larger document here.
Gypsy moth larvae, Lymantria dispar (L.), are major pest defoliators in most of the United States and destroy millions of acres of trees annually. They are highly polyphagous and display a wide host plant preference, feeding on the foliage of hundreds of plants, such as oak, maple, and sweet gum. Lepidopteran larvae, such as the gypsy moth, depend largely on their gustatory and olfactory sensory organs (sensilla) to find food sources. Feeding behavior is controlled by input from the mouthpart gustatory sensilla.
