Blaptica dubia , Dubia roach , also known as orange-spotted roach , , or Argentine cockroaches , is a medium-sized cockroach species that grows about 40-45 mm (1.6 to 1.8 inches). They are sexually dimorphic; adult males have full wings covering their bodies, while women have only small masked wings, their forewings are in about a quarter of their body length.
Adults are dark brown to black with a pattern of orange spots/lines that are sometimes seen only in bright light. The colors are slightly different from the environment and diet from one colony to another.
Blaptica dubia is ovoviviparous, giving birth to a young life, and can give birth to 20 to 40 nymphs per month under favorable conditions.
Dubia cockroaches are found in Central and South America, beginning in Costa Rica. It is common from French Guiana and Brazil to Argentina.
Documented specimens have been found in Brazil, Argentina and Uruguay.

Flights
Though rarely known to fly, adult males have fully developed wings, and pigmented muscles typical of cockroaches are able to meet the immediate energy needs of sustainable flight. In laboratory tests launched from the 2.5 m high road, adult men dubia are able to improve their dorso-ventral position and rapidly spread their wings to control and direct their offspring; However, active active flights do not maintain or increase their altitude. Adult females only have an imperfect forsing and muscle deficiency required to fly, and do not show flight control in the test launch.

Ascending
Both adults and teenagers can not climb a smooth vertical surface, because they do not have an arolium that develops. However, teenagers have been known to climb the surface of silicon, and the plastic side of the container.
Habitat
The ideal temperature range is the higher end of the range 24 Â ° C - 35 Â ° C. They will not breed below 20 Â ° C. They will not succeed if the moisture is too low. Dubia's cockroaches can tolerate a lower humidity than many other roach species. This roach species will also confiscate more water in its body when it is fed on fruit and water will be released during stress.
In captivity, the dampness of the cage is less important than the high-flow food supply, negating the need to obscure the cage completely compared to some other species of tropical pet insects. The catch habitat should be kept clean and dry to keep the feces stool dry and does not provide a medium for bacterial or fungal growth. Vertically stacked egg crates are helpful in this regard, as does good airflow.
Diet
Cockroach Dubia is a frugivore who prefers fruits and grains, avoiding high-protein sources such as flesh dung or wastes from other animals. They especially like the semisweet vegetable ingredients. The right bait to keep Dubia's cockroach includes: carrots, all kinds of tropical fruits (mango and papaya), apples, avocados, bananas, cherries, pears, oranges, strawberries, fresh corn, tomatoes (some individuals are not interested in tomatoes while others eat easy), and lettuce (not iceberg or romaine) - lots of other green vegetables will be welcome. All dried cat/dog based foods, fish food, crested gecko food and bearded dragon food can also be used to supplement their food. They will also consume whole-grain bran and germ-based foods such as assorted breads, unhealthy breakfast cereals (such as Cheerios or Special K), and even smoothed pastes, although such diets should be supplemented with edible vegetation and fruits a kind. provide enough water.
The high starchy tubers like potatoes and sweet potatoes are eaten in disgust and apparently only because of their water content.
Nymphia born new born seems to depend on adult waste to survive.
Too much protein in dubia can cause gout and potentially death in the colonies and animals that eat it.
Life cycle
- Marriage occurs when men keep sperm packets in women. These sperm packets inhibit females from further mating.
- B. dubia is ovovivoparous as it is, the eggs hatch inside the woman's body.
- Pregnancy about one month (28 days).
- The nymphs hatch inside the female. Between 20 and 40 young people, each about 2 mm, are produced in each clutch.
- Adult nymphs are about 4-6 months depending on the temperature and supply of food.
- Nymphs undergo 7 instars, the pronotum grows about 25% between molts, before reaching adulthood.
- Adults live 1-2 years.
Use as a feeder insect
Blaptica dubia has become a popular feed insect, especially among tarantula, amphibian and reptile enthusiasts. Keeping or breeding insects becomes easier because of their inability to jump or climb smooth surfaces, relatively slow motion, and flight shortages. They are also quiet, unlike crickets, and the requirements of the tropical environment reduce the chances of escape formation in cold, dryer climates. B. dubia can cause allergic reactions in humans, although they produce relatively few smells compared with many cockroaches.
A study found other cockroaches (Turkestan cockroaches ("red runners"), Madagascar hissing cockroaches) provide a high-protein, low-fat nutritional composition similar to crickets, more than those provided by mealworms or superworm larvae. The intestinal contents of the cockroach, depending on its diet, can provide essential nutrients that are not available from cockroaches with empty intestines. The content of vitamins and minerals in the studied cockroaches is well represented except for low calcium: a typical phosphorus ratio in cockroaches, and relatively low vitamin A and E in breeding cockroaches. This nutritional supplementation in a feeding cockroach may be recommended. A study of panther chameleon ( Furcifer pardalis ) found vitamin A deficiency shortened life span and reduced reproductive rate.
Some US states do not allow imports by the general public B. dubia , considered by some to be invasive species. A Florida man was arrested on crime charges in 2011 linked to ordering 500 B dubia via the internet using a doctor's permission, usually issued to researchers.
Reproduction
B. dubia is an ovoviviparous species, generally giving birth to young, and pregnancy in one study lasts 48-64 days, in a 26 ° C environment with 12 hours light and dark photoperiod. It carries ootheca (egg capsule), which stores about 20-35 eggs, until they are ready to hatch, or may drop earlier under stressful conditions. Adults live up to 2 years, women are longer than men. The rate of growth and reproduction is sensitive to environmental conditions, optimum 25-30 Â ° C and above 60% relative humidity.
