What do cockroaches eat?
Cockroaches are generally omnivorous; the American cockroach ( Periplaneta americana ), for example, feeds on a great variety of foodstuffs including bread, fruit, leather, starch in book bindings, paper, glue, skin flakes, hair, dead insects and soiled clothing. Many species of cockroach harbor in their gut symbiotic protozoans and bacteria which are able to digest cellulose. In many species, these symbionts may be essential if the insect is to utilize cellulose; however, some species secrete cellulase in their saliva, and the wood-eating cockroach, Panesthia cribrata, is able to survive indefinitely on a diet of crystallized cellulose while being free of microorganisms.

How many species of cockroaches are there?
Cockroaches are members of the order Blattodea, which includes the termites, a group of insects once thought to be separate from cockroaches. Currently, 4,600 species and over 460 genera are described worldwide. The name " cockroach " comes from the Spanish word for cockroach, cucaracha, transformed by 1620s English folk etymology into "cock" and "roach". The scientific name derives from the Latin blatta, "an insect that shuns the light", which in classical Latin was applied not only to cockroaches, but also to mantids.

Blattidae. Corydiidae. Cryptocercidae. Ectobiidae. Lamproblattidae. Nocticolidae. Tryonicidae. Cockroaches (or roaches) are insects of the order Blattodea, which also includes termites. About 30 cockroach species out of 4,600 are associated with human habitats.
Why are cockroaches used in biology?
Because of their ease of rearing and resilience, cockroaches have been used as insect models in the laboratory, particularly in the fields of neurobiology, reproductive physiology and social behavior. The cockroach is a convenient insect to study as it is large and simple to raise in a laboratory environment. This makes it suitable both for research and for school and undergraduate biology studies. It can be used in experiments on topics such as learning, sexual pheromones, spatial orientation, aggression, activity rhythms and the biological clock, and behavioral ecology. Research conducted in 2014 suggests that humans fear cockroaches the most, even more than mosquitoes, due to an evolutionary aversion.
What is the name of the cockroach that digests wood?
The brown-hooded cockroach ( Cryptocercus punctulatus) digests wood with the aid of certain protozoans in its digestive tract. Some authorities consider cockroaches to be a suborder of either the order Orthoptera ( grasshoppers, crickets, and katydids) or the order Dictyoptera ( mantids and cockroaches).

What is the best environment for cockroaches?
The cockroach prefers a warm, humid, dark environment and is usually found in tropical or other mild climates. Only a few species have become pests. The insect damages more material than it consumes and emits a disagreeable odour. The diet of the roach, which includes both plant and animal products, ranges from food, paper, clothing, and books to dead insects, especially bedbugs. Insecticides are used in roach control.
How long does it take for an ootheca to produce?
The female produces the ootheca 3 days after mating and carries it for about 20 days. Three or more generations may occur yearly. Because it is small (about 12 mm [less than 0.5 inch] long), this cockroach often is carried into homes in grocery bags and boxes.
What is the name of the roach?
Alternative Titles: Blattaria, Blattodea, roach. Cockroach, (order Blattodea), also called roach, any of about 4,600 species of insects that are among the most primitive living winged insects, appearing today much like they do in fossils that are more than 320 million years old. The word cockroach is a corruption of the Spanish cucaracha.
What are the exoskeletons of arthropods?
Arthropods are characterized by their jointed appendages, which are their legs, and tough exoskeletons. An exoskeleton is essentially what it sounds like: an external skeleton. It is a protective covering made of protein and a hard substance called chitin. Although this outer covering varies in thickness and flexibility, in arthropods such as cockroaches it is akin to a coat of armor. You have probably stepped on a bug and felt the crunch beneath your feet. With cockroaches this is not so easy. Their exoskeletons are so rigid that you really have to put some effort in to kill them with your shoe.
What kingdom are cockroaches in?
The cockroach belongs in the Animalia kingdom, just like you and I. That is essentially where our commonalities end, thankfully. From there, the cockroach divides off into phylum Arthropoda, a term literally meaning ''jointed appendages.'' With over a million species, arthropods make up the most diverse and numerous group to ever inhabit the earth. When you take into account that insects are included in this group, it's easy to understand why they are found literally everywhere. Other familiar members of this phylum include crustaceans such as crabs, lobsters, and spiders.
What are the characteristics of a cockroach?
Let's look at these specific traits on the cockroach. We find the three bodily sections, as well as compound eyes and antennae on the head. Also on the head of the cockroach are mouthparts adapted for biting, chewing, and grinding. This allows these omnivorous creatures to forage just about anywhere. The search for food is what brings them as uninvited guests into our homes, as they enjoy our pantry items and leftovers.
What are the three parts of an insect?
Although highly varied, insects have many traits in common. Every insect has three distinct body sections: the head, abdomen, and thorax. On the head we find a pair of compound eyes and a pair of antennae. Mouthparts are present, adapted for piercing, sucking, chewing, or biting, depending on the creature. It comes as no surprise that many (though not all) insects have one or two pairs of wings which are attached to the thorax. In addition, three pairs of jointed legs are also present.

What are the two pairs of wings that a cockroach has?
Each thoracic segment gives rise to a pair of walking appendages (known as cursorial legs). The organism bears two pairs of wings. The fore wings, known as tegmina, arise from mesothorax and are dark and opaque. The hind wings arise from the metathorax and are used in flight, though cockroaches rarely resort to flight.
What is the largest cockroach in the world?
The American cockroach ( Periplaneta americana) is the largest species of common cockroach, and often considered a pest. In certain regions of the U.S. it is colloquially known as the waterbug, though it is not a true waterbug since it is not aquatic. It is also known as the ship cockroach, kakerlac, and Bombay canary.
What is the American cockroach genome?
The American cockroach genome is the second-largest insect genome on record, after Locusta migratoria. Around 60% of its genome is composed of repeat elements. Around 90% of the genome can be found in other members of Blattodea. Genetically, the American cockroach is closer to two termite species, Zootermopsis nevadensis and Macrotermes natalensis, than it is to the German cockroach. The genome codes for a large number of chemoreceptor families, including 522 taste receptors and 154 olfactory receptors. The 522 taste receptors comprise the largest number found among insects for which genomes have been sequenced. About 329 of the taste receptors are involved in bitter taste perception. These traits, along with enlarged groups of genes relating to detoxification, the immune system, and growth and reproduction, are believed to be part of the reasons behind the cockroach's ability to adapt to human living spaces.

How many stages of life do cockroaches have?
Life cycle. American cockroaches have three developmental stages: egg, nymph, and adult. Females produce an egg case ( ootheca) which protrudes from the tip of the abdomen. On average, females produce 9–10 oothecae, although they can sometimes produce as many as 90.
What is the morphology of a cockroach?
Morphology. The American cockroach shows a characteristic insect morphology with its body bearing divisions as head, trunk, and abdomen. The trunk, or thorax, is divisible into prothorax, mesothorax and metathorax. Each thoracic segment gives rise to a pair of walking appendages (known as cursorial legs).

Most species of cockroach are about the size of a thumbnail, but several species are larger. The world's heaviest cockroach is the Australian giant burrowing cockroach Macropanesthia rhinoceros, which can reach 8 centimetres (3 in) in length and weigh up to 35 grams (1.2 oz). Comparable in size is the Central American giant cockroach Blaberus giganteus. The longest cockroach species is Megaloblatta longipennis, which can reach 97 mm (3+7⁄8 in) in length and 45 mm (1+3⁄4 in) across. A Central and South American species, Megaloblatta blaberoides, ha…
Distribution and habitat
Cockroaches are abundant throughout the world and live in a wide range of environments, especially in the tropics and subtropics. Cockroaches can withstand extremely low temperatures, allowing them to live in the Arctic. Some species are capable of surviving temperatures of −122 °C (−188 °F) by manufacturing an antifreeze made out of glycerol. In North America, 50 species separated into five families are found throughout the continent. 450 species are found in Australia. Only about four widespread species are commonly regarded as pests.
Cockroaches are social insects; a large number of species are either gregarious or inclined to aggregate, and a slightly smaller number exhibit parental care. It used to be thought that cockroaches aggregated because they were reacting to environmental cues, but it is now believed that pheromones are involved in these behaviors. Some species secrete these in their feces with gut microbial symbionts being involved, while others use glands located on their mandibles. Pheromones produced by the cuticle may enable cockroaches to distinguish between differe…

Cockroaches were known and considered repellent but medicinally useful in Classical times. An insect named in Greek "σίλφη" (silphe) has been identified with the cockroach, though the scientific name Silpha refers to a genus of carrion beetles. It is mentioned by Aristotle, saying that it sheds its skin; it is described as foul-smelling in Aristophanes' play Peace; Euenus called it a pest of book collections, being "page-eating, destructive, black-bodied" in his Analect. Virgil named the cockroach "Lucifuga" ("one that avoids light"). Pliny the Elder recorded the use of "B…
