Cockroaches use pheromones to attract mates, and the males practice courtship rituals, such as posturing and stridulation. Like many insects, cockroaches mate facing away from each other with their genitalia in contact, and copulation can be prolonged. A few species are known to be parthenogenetic, reproducing without the need for males. [27]
Like other cockroaches, T. petiveriana uses chemical pheromones to communicate with each other. When disturbed, they are said to raise their wings and evert lateral glands on the second and third abdominal segments. Their glandular secretions were found to contain volatile compounds N-3-methylbutylacetamide (MBA) and N-3-methylbutylpropanamide ...
Immature cockroaches emerge from egg cases in 6–8 weeks and require 6–12 months to mature. After hatching, the nymphs feed and undergo a series of 13 moultings (or ecdysis). Adult cockroaches can live up to an additional year, during which females produce an average of 150 young. The American cockroach reproductive cycle can last up to 600 ...
Ahead, entomologists explain why you don't really need to worry about cockroach bites—but rather how they can make you sick if you have an infestation. Ahead, entomologists explain why you don't ...
The discovery could explain why cockroaches are considered such great survivors and able to adapt to inhospitable surroundings. Study: Cockroaches may be creepy, but they have distinct ...

Cockroaches are experts at surviving indoors, hiding in kitchen pipes or musty drawers. A new study uses genetics to chart cockroaches' spread across the globe, from humble beginnings in southeast ...
Blaberus giganteus is considered one of the largest cockroaches in the world, with males reaching lengths of up to 7.5 cm (3.0 in) and females 10 cm (3.9 in), [2] although others list 9 cm (3.5 in) as the maximum length. [3] These cockroaches are lightly built with flattened bodies, allowing them to hide in cracks from predators.
