Cockroaches commonly known as cockroaches, cockroaches are Insecta head (blattaria), the world's known about 3,700 species, mostly in tropical and subtropical areas, a few distributed in temperate regions. China has 60 genera and 18 families recorded 240 kinds, are distributed throughout the country. Shape: oval adult cockroaches, dorsal flat, the elderly body up to 100mm, while only a small 2mm, usually 10 ~ 30mm, takes the shape of brown or dark brown, vary by species, with a glossy surface sheen. Head: small and bent down so easily, y-shaped bonnet seam obvious, covering most of chest. Large compound eyes, antennae around the base; the monocular 2. Slender whip-like antennae were up to more than 100 sections. Mouthparts of chewing. Chest: chest well developed, oval or slightly rounded back, and some types of surface with markings; during and after a smaller chest, can not be clearly differentiated. Leathery wing, left wing on the right wing in the next, each coverage; membranous hind wings. Few types of wingless. The availability and size of the shape of the wings is classified according to one of the cockroaches. Hairy feet thick, flat base section of the vast, covering almost all of the web, for Rush. Abdomen: flat wide, divided into 10 sections. 6, 7 have scent glands on the back of the opening section; Section 10 Health and one pair on the back of the tail section to be. End of sessions required, also the length and shape classification. The web of the last male of abdominal stab Health 1, no female abdominal spines, whereby male and female, respectively. Female's web for the last lobulated structure, with a sheath holding the role of eggs. Life history: for the gradual metamorphosis of insects, cockroaches, life history have eggs, nymphs and adults three developmental stages. Eggs and egg pods: females lay eggs excrete a substance prior to the formation of ootheca (egg pods). The sheath hard, dark brown, mostly for long 1cm, purse-like shape. Eggs arranged in pairs within which the queue. Female egg pod discharged, often after the end of the folder in the abdomen, until hatching a small number of species, most species and then secrete sticky substances that adhere to objects on the egg cases. Each ootheca contains 16 to 48 eggs. Ootheca egg shape and number of cockroaches contain important basis for classification. Egg egg sheath usually 1 to 2 months after hatching. Nymph: nymph cockroaches have a pre-period, that has just hatched, the antennae, mouthparts and feet were collected and fixed in the ventral, subject to a molt, did not become normal active state of nymphs. Nymphs small, pale wingless, immature reproductive organs, habits and adults are similar. Nymphs after 5 to 7 age development before emergence of adults. Each age is about 1 month. Mating immediately after adult emergence, about 10 days after mating began to lay eggs. Life of a female can lay several or dozens of sheath ranges. The time required for the entire life cycle of insect species, temperature, nutrition varies, it generally takes several months or more. Female life expectancy of about six months, male life expectancy is shorter. Ecology: 1. Feeding roach is omnivorous insects, and animals' food, faeces and secretions, and garbage can for food, especially meat addicted to sugar classes and class, and need regular water. Cockroaches of the anti-hunger strong force, German cockroaches in the water can survive without food when 10 to 14 days, there is food in the water when the survival of 9 to 11 days without food in the water can survive under conditions of 1 week . In excessive hunger, and sometimes cannibalism seen cockroaches and egg cases of its kind. 3. Seasonal fluctuation and seasonal dynamics of wintering cockroaches influenced by temperature, the same insect species in different regions may show different seasonal distribution. In most parts of China, cockroaches are usually only found in April, reached a peak from July to September, October and then gradually reduced until it disappears. When the temperature is below 12 ℃, it took adults, nymphs or eggs in the dark, hidden places without winter wind. Cockroaches our main categories: 1. German cockroaches (blattella germanica) body length 1.2 ~ 1.4cm, pale brown. Pronotum with two black vertical lines on. Eggs small and flat, thin sheath, containing 20 to 40 eggs. Is the dominant species widely distributed in China, more common in cars, boats, aircraft and other transport vehicles. 2. American cockroach (periplaneta americana) body length of 3.5 ~ 4.0cm, dark brown. Antennae very long. Pronotum yellow edge bands, middle brown butterfly spots. Egg sheath with eggs 16. Also the dominant species widely distributed in China. More common in kitchens, storage rooms and toilets, etc.. In addition, the Australian cockroach (p.australasiae), Periplaneta fuliginosa (p.fuliginosa) and the Oriental cockroach (blatta orientalis). Relationship with disease Cockroaches through the body surface or body (in gut-based) to carry a variety of pathogens and mechanically transmitted diseases. In recent years, reports the disease from bacteria isolated from cockroach body 5, Salmonella paratyphoid A and B strains 5, 43 Pseudomonas aeruginosa, Proteus 8, Penicillium, Aspergillus and other fungi, adenovirus 60, enterovirus serotype 15, polio virus, 8 and hepatitis B surface antigen, also detected the worm (roundworm, hookworm, whipworm, pinworm, tapeworm, etc.) eggs and amoeba, Giardia package capsule. Cockroaches can be used as long Hymenolepis, beautiful tube worm, tube worms East, read the first strains of insects and reduce spine Hymenolepis the intermediate host. In addition, foreign reports can be a cockroach allergens, causing allergic reactions. Prevention Keep indoor sanitation, proper food preservation, and timely garbage collection is a fundamental measure to control cockroaches. Cockroaches season activities under both the law and concentrate, repeated assault, to completely eliminate it. 1. Ootheca manual removal cabinets, boxes, cabinets and other cracks in the egg cases, kill to be burned or hot. 2. In addition to adult trapping with box traps or hunting, the main use of chemical drugs to kill. In recent years, permethrin, deltamethrin,-cypermethrin and other pyrethroids made "cockroaches pen" out of place in the cockroach scrawling, or made into tablets, paper, medicine, medicine board to place its venues, or spray paint on interior walls made of the results are good, for home use. In addition to the family, but on hotels, restaurants and cars, boats and other vehicles also need to take measures. It is believed that in these places, the use of spray (such as Permethrin) plus bait (such as trichlorfon) prevention and control system can receive a more significant effect. But pay attention to safety and the timely removal of dead parasites. In addition, it was reported cockroach resistance to the pyrethroid is easy to produce, it is worth attention. Cockroaches can also be used as medicine, common land turtle species is Ji (polyphagaplancyi), back to Long abdomen, chest hair; winged males, females wingless. Chinese soft-shelled turtle (p.sinensis). Release name: stone ginger, negative plate, sliding insects, insect woman tea, incense lady. Smells: salty, cold, toxic. Indications: bleeding, Kennedy disease, cold and heat, under the gas, Lee blood. With this known side cockroach cockroaches, Suzhou folk for the treatment of children caused by Queru Xingshou Shenpi, bloating diarrhea on sickness.

This model can be effective against the escape and the temperature is a better mode of large-scale breeding cockroaches. Can be built in an enclosed indoor pool or a fight, and then placed in culture in which box. 2, with a wooden support. This model for the early small-scale attempts to raise that in a wooden box across the multi-layer, full use of space to farm. 3, mixed farming land per cockroach. This model can effectively improve the breeding efficiency, indoor use in the soil per breeding their similarities and differences, the main element is buried soil and the cockroaches are not buried this feature effectively complement each other.
