Other species of cockroaches, however, can produce far more eggs; in some cases a female needs to be impregnated only once to be able to lay eggs for the rest of her life. [27] The female usually attaches the egg case to a substrate, inserts it into a suitably protective crevice, or carries it about until just before the eggs hatch.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
Cockroaches can pick up disease-causing bacteria, [19] such as Salmonella, on their legs and later deposit them on foods and cause food poisoning or infection if they walk on the food. House dust containing cockroach feces and body parts can trigger allergic reactions and asthma in certain individuals.
B. dubia can cause allergic reactions in humans, [12] although they produce relatively little odor compared to many cockroaches. [ 9 ] A study found other cockroaches ( Turkestan ("red runner") cockroaches , Madagascar hissing cockroaches ,) provided a high-protein, low fat nutrition composition similar to crickets, more so than mealworms or ...
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 ...
Male butterflies use a wide range of chemicals as sex pheromones, for example pyrrolizidine alkaloids, terpenes and aromatic compounds such as benzaldehyde. Research into the chemical communication of insects is expanding our understanding of how they locate their food sources or places to lay eggs.
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 ...
The Florida woods cockroach (Eurycotis floridana) is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). [2] When alarmed, adults can eject an extremely foul-smelling directional spray up to one metre (3.3 ft), [3] which inspired several of its other common names: Florida skunk roach, Florida stinkroach, skunk cockroach, skunk roach, stinking cockroach ...
