Habitat

edit

Firebrats prefer relatively warm temperatures (36–39 °C) and require some humidity.[2] They are commonly found indoors near heat sources such as furnaces and boilers. They feed on a wide variety of carbohydrates and starches that are also protein sources such as dog food, flour and book bindings. They are distributed throughout most parts of the world and are normally found outdoors under rocks, plant litter, and in similar environments, but are also often found indoors where they are considered pests. They do not cause major damage, but they can contaminate food, damage paper goods, and stain clothing. Otherwise they are mostly harmless.

Behavior

edit

Firebrats utilize pheromones to lead other firebrats to attract one another and congregate. To maintain a group, firebrats must remain in contact with one another.[3]

Breeding

edit

At 1.5 to 4.5 months of age the female firebrat begins laying eggs if the temperature is right (32–41 °C or 90–106 °F). It may lay up to 6000 eggs in a lifetime of about 3–5 years. After incubation (12–13 days), the nymphs hatch. They may reach maturity in as little as 2–4 months, resulting in several generations each year.

Meiosis

edit

The sequential changes occurring during the prophase I stage of meiosis in T. domestica ovaries have been described in detail.[4]
