Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] This interaction is mostly mediated by the secretion and detection of chemicals (semiochemical) in the environment by insects. [2] Semiochemicals are secreted by the organisms (including insects) in the environment ...
Insects have had millions of years to evolve mechanical defenses. Perhaps the most obvious is the cuticle. Although its main role lies in support and muscle attachment, when extensively hardened by the cross-linking of proteins and chitin, or sclerotized, the cuticle acts as a first line of defense. [5]
The majority of insect use in medicine is associated with Central America and parts of South America, rather than North America, and most of it is based on the medical techniques of indigenous peoples. [2] Currently, insect medicine is practiced much more rarely than in China, India, or Africa, though it is still relatively common in rural ...
mouthparts. Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata ...
Insect physiology includes the physiology and biochemistry of insect organ systems. [1] Although diverse, insects are quite similar in overall design, internally and externally. The insect is made up of three main body regions (tagmata), the head, thorax and abdomen. The head comprises six fused segments with compound eyes, ocelli, antennae and ...
An insect 's respiratory system is the system with which it introduces respiratory gases to its interior and performs gas exchange. Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system ...
Baculoviridae. Baculoviridae is a family of viruses. Arthropods, among the most studied being Lepidoptera, Hymenoptera and Diptera, serve as natural hosts. Currently, 85 species are placed in this family, assigned to four genera. [1][2][3] Baculoviruses are known to infect insects, with over 600 host species having been described. Immature ...
Insects live in a world of motion. This leaf-footed bug climbs wind blown grass and flies off. Insects (from Latin insectum) are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs ...
