History Of Cockroaches

The word “Cockroach’’ comes from Spanish word “Cucaracha” which means “Crazy Bug”

Cucaracha transformed by 1620s English Folk Etymology into Cock and Roach (Cockroach)

120 million years before Dinosaurs 50-60 species in United States Prefer warm,humid and dark areas Favorite Food; Decaying and Organic matter Can live without head for an entire week Earliest Cockroaches like fossils(Roaches) from

Carboniferous Period 350 million years ago

Dinosaur-Age Cockroach

Important Species American Cockroaches (Periplaneta americana) Brown Banded cockroaches (Periplaneta

brunna) German Cockroaches (Blattela germanica) Oriental cockroaches (Blatta orientalis)

Distinguished Features Omnivores Reddish brown, 3 to 5 cm in length

and 1.5 to 2cm in breadth Nocturnal Oval, flattened body shape Thorax covered by large

plate(pronotum) Chewing (Mandibulate mouthparts)

Compound eyes and simple eyes or ocelli like spotsMale genetalia asymmetrical and cerci larger than styleLong and Setaceous ( Bristle like) AntennaEggs present in Ootheca, (Chitinous bodyHypognathousTegmina legs Cursorial

Comparison Of Blattaria And Mantodea

Blattodea Head is not mobile in all

directions Pronotum is shield like

and cover the part of thorax

Body is flattened Antenna long and

setaceous Legs are cursorial type Ootheca is chitinous Omnivores Common family; Blattidae

e.g. American Cockroach

Mantodea Head is mobile Pronotum is elongated

and do not cover the head

Body elongated and some cylindrical

Long and filiform antenna

Legs are raptorial type Carnivores Common family;

Mantidae e.g. Preying mantid

Morphology of male and female cockroach

Typical Mouthparts and Leg

Chewing Type Mouthparts

Cursorial Leg of Roach

Engrossing Features Can run on two legs and speed

almost 5 ft per second and Maximum speed 3 miles per hour

Higher radiation resistance than vertebrates

4 times faster than Cheetah The world’s heaviest cockroach They can live full month without any

food and two weeks without water Species have wings but not ability to fly

like German Cockroach

Litter bug

Do not speak but one variety is exception . The Madagascar Hissing Cockroach is being only insect that uses its air passageway to produce sound CRAMUsed in Movies Super food in future Racing Cockroach Novel SPRC World Record Song “La Cucaracha” Half life (Science-fiction video game)

EFFECTS OF COCKROACHES Food contamination Inoculation of disease causing

bacteria Cockroaches biting Invasion of body parts Food poisoning Asthma Allergies

REMEDIES Keep your house clean Clean the food preparation area Empty dustbins in your kitchen

should be cover always Sealed containers Never keep old newspapers ,

magazines and books Avoid use of foggers , bombs or

aerosol sprays Cockroaches baits and sprinkle Boric

acid Block all entrances

Catnip Tea (Nepetalactone)Use Bay leaves (powerful fragrance)Sugar + Baking Soda SolutionPine sol + BleachBoraxListerine (act as hindrance)Cayenne Pepper+ Garlic + Clove+ OnionCoffee groundsMint Oil sprayGarlic PowderFipronilGuardian powder

Significance In Ecosystem Considered Mother Nature Recyclers Involve in Pollination Part of food chain Used in Medicine: Lafcadio Hearn (1850-

1904) Cockroach Tea used for Tetanus, By Aristotle Silphe used for Injury

A poultice of boiled cockroaches placed over wound

Fried with garlic for digestionFarming in ChinaSeveral species like Blaptica dubia as a food for insectivores

Used for space tests: A cockroach given name “Nadezhda” was sent into space by Russian Scientists during Foton-M Test

Become first terrestrial animal to give birth in space

Vostok Spacecraft

Clusia aff. sellowiana

As a Pollinator

Part of food chain As a Token insect in MoviesIt could Potentially live up without headCan be trained like dogsAs a food for birds, lizard and larger insects
