Students will be able to recognize what insects eat based on what type of mouthparts they have. 31 March - 6 April. MORPHOLOGY OF INSECT MOUTHPARTS Erik Smith. 9) Stick and Leaf Insect Order – Phasmida Examples of Families Why should we study mouthparts? 24 March - 30 March. These consist of the labrum forming upper lip, mandibles, first maxillae, second maxillae forming lower lip, hypo pharynx and the epipharynx. TEKS: Science: 2.2a, 2.2b, 2.5a, 2.6a, 2.6b, 2.6d Insect mouthparts: ascertaining the paleobiology of insect feeding strategies.Annual Review of Ecology and Systematics, 153-193.; There have also been consulted the personal notes taken from the subject “Biology and Diversity of Arthropods” given during the course 2013-2014 at the Universidad Autònoma de Barcelona. Insect mouth parts. This strong structure provides protection for the brain, support for eyes, ocelli, antennae and mouthparts. Biting and Chewing: This type of mouth parts are supposed to be the most primitive type as the other types are believed to be evolved from biting and chewing type of mouth parts. the insect head can be found in the mouthpart module. Each species is perfectly suited to its role, and their mouthparts have evolved in ways that allow them to effectively exploit their food sources. The Mouth Parts: They have chewing mouthparts. These types of mouth parts are present in almost all the bloodsucking insects like tse-tse fly, bed bug etc. Types of insect mouthparts. Six or seven segments are condensed to form the head capsule. In dragonfly naiads (immatures), the labium has become adapted as a prehensile tool that can be rapidly extended forward to catch prey. insects Article Propolis Envelope Promotes Beneficial Bacteria in the Honey Bee (Apis mellifera) Mouthpart Microbiome Hollie Dalenberg 1, Patrick Maes 2, Brendon Mott 3, Kirk E. Anderson 3,* and Marla Spivak 1 1 Department of Entomology, University of Minnesota, St Paul, MN 55108, USA; dalen034@umn.edu (H.D. Instructions: Read the passage either in groups or as a class Objectives: Students will know the types of insect mouthparts. First, because insects are ubiquitous residents of virtually all terrestrial and freshwater habitats and have elevated taxonomic diversity and ecomorphologic disparity, their mouthparts represent a broad spectrum of feeding modes that are ideal for comparative studies. various insect mouthparts and how they are adapted for their environment. ADAPTATIONS OF THE MOUTHPARTS. Metamorphosis: They undergo incomplete (simple) metamorphosis with the nymphs looking like small versions of the adults (with underdeveloped wings). 1. No mouthpart specializations to petal-feeding are reported in flower-visiting insects. 21 April - 27 April. The mandibulate mouthparts are reduced in size allowing the insect to excavate a deep narrow hole that is used for feeding, and perhaps later, as a site for oviposition. 28 April - … The strongest muscles in the head serve the mandibles in chewing insects and the sucking pump in piercing-sucking insects. Labandeira, C. C. (1997). Significance to Humans: They can be very destructive to crops. Some butterflies and few Diptera extract nutrients from pollen by mixing it externally with saliva on their mouthparts. Metamorphosis: Holometabolous Mouthparts: Piercing-sucking, cutting-sponging, sponging, chewing, cutting-lapping Key characteristics: Second pair of wings reduced in size I may have combined some ideas from those books, but I think I mostly followed this lesson plan here for this activity. There are some other good lesson plan ideas about Insects … 14 April - 20 April. Several of the books I got from the library suggested ways to demonstrate different types of insect mouthparts. Female mosquitoes feed on … Hemimetabolous insects have similar type of mouthparts in their larvae and adults. Pollen-piercing mouthparts occur in Thysanoptera and one group of Diptera. ); spiva001@umn.edu (M.S.) 7 April - 13 April. The mouthparts of female mosquito are piercing and sucking type. one group of basal Hymenoptera. Quiz-Lecture-4. Mouth Parts in Insects! Mouthparts: Chewing Key characteristics: Forceps-like cerci at the tip of the abdomen Significance: Beneficial (05) Order: Diptera Common name: Fly, midge, mosquito, etc. Insects are incredibly diverse organisms, and they fill a variety of niches in their respective ecosystems.
