Carboniferous Period 350 million years ago
Dinosaur-Age Cockroach

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
