Millipedes can be an unwanted nuisance particularly in greenhouses where they can potentially cause severe damage to emergent seedlings. Most millipedes defend themselves with a variety of chemicals secreted from pores along the body, although the tiny bristle millipedes are covered with tufts of detachable bristles. Its primary defence ...
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
Narceus americanus is a large millipede of eastern North America. Common names include American giant millipede, [1] worm millipede, and iron worm. [2] It inhabits the eastern seaboard of North America west to Georgetown, Texas, north of the Ottine wetlands. [3] It has a nearly cylindrical gray body, reaching a length of 4 inches (100 mm). [4]
Wild wedge-capped capuchin monkeys (Cebus olivaceus) self-anoint with millipedes (Orthoporus dorsovittatus).Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects [6] and the secretions are thought to provide protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
Polydesmida (from the Greek poly "many" and desmos "bond") is the largest order of millipedes, with more than 5,000 species, [2] [3] including all the millipedes reported to produce hydrogen cyanide (HCN). [4] This order is also the most diverse of the millipede orders in terms of morphology. [5]
Mastigoproctus giganteus lives in the southern US and in Mexico at elevations up to 6000 meters. [4] It preys on various insects, worms, and slugs. [5] It is an efficient predator that feeds at night on a variety of arthropods, primarily insects such as cockroaches and crickets, as well as millipedes and other arachnids.
Mandibulates include the crustaceans, myriapods (centipedes and millipedes), and all true insects. The name "Mandibulata" refers to the mandibles , a modified pair of limbs used in food processing, the presence of which are characteristic of most members of the group.
Pill millipedes are relatively short-bodied compared to most other millipedes, with only eleven to thirteen body segments, [2] and are capable of rolling into a ball when disturbed, as a defense against predators. This ability evolved separately in each of the two orders, making it a case of convergent evolution, rather than homology.
