Manduca
hornworms, hawkmoths, sphinx moths
Manduca is a genus of hawkmoths (Sphingidae) established by Jacob Hübner in 1807. The genus contains approximately 70 species distributed primarily in the Americas. Several species, notably Manduca sexta (tobacco hornworm) and M. quinquemaculata (tomato hornworm), are extensively studied as model organisms in biological research due to their large size and ease of laboratory rearing. The larvae, commonly called hornworms, are significant agricultural pests of solanaceous crops.
Nauphoeta cinerea
Cinereous Cockroach, Speckled Cockroach, Lobster Cockroach
Nauphoeta cinerea is a circumtropical cockroach species native to northeastern Africa that has achieved global distribution through human association. Commonly known as the cinereous, speckled, or lobster cockroach, this species is frequently used as a laboratory model for studying social behavior, neurobiology, and reproductive physiology. Males establish strict dominance hierarchies that determine territorial rights and mating access, with social status mediated through pheromonal communication and acoustic stridulation. The species has been documented harboring Wolbachia endosymbionts of the F clade, which may provide nutritional benefits.
