HORTICULTURE

Detailed explanation-1: -A chewing insect has a pair of mandibles, one on each side of the head. The mandibles are caudal to the labrum and anterior to the maxillae . Typically the mandibles are the largest and most robust mouthparts of a chewing insect, and it uses them to masticate (cut, tear, crush, chew) food items.

Detailed explanation-2: -The basic segmental character of the mouthparts is most apparent in insects that bite off fragments of food and then chew it before ingesting it (Fig. 1). Insects that do this are said to be “mandibulate” because the mandibles are relatively unmodified compared with those of fluid-feeding insects (see below).
