Insect repellent. A mosquito coil. An insect repellent (also commonly called " bug spray ") is a substance applied to the skin, clothing, or other surfaces to discourage insects (and arthropods in general) from landing or climbing on that surface. Insect repellents help prevent and control the outbreak of insect-borne (and other arthropod ...
Repellent trail markers may help ants to undertake more efficient collective exploration. The army ant Eciton burchellii provides an example of using pheromones to mark and maintain foraging paths. When species of wasps such as Polybia sericea found new nests, they use pheromones to lead the rest of the colony to the new nesting site.
A neuron (green and white) in an insect brain (blue) Insect cognition describes the mental capacities and study of those capacities in insects. The field developed from comparative psychology where early studies focused more on animal behavior. [1] Researchers have examined insect cognition in bees, fruit flies, and wasps.
Sterile insect technique. The screw-worm fly was the first pest successfully eliminated from an area through the sterile insect technique, by the use of an integrated area-wide approach. The sterile insect technique ( SIT) [1] [2] is a method of biological insect control, whereby overwhelming numbers of sterile insects are released into the wild.
Insect olfaction refers to the function of chemical receptors that enable insects to detect and identify volatile compounds for foraging, predator avoidance, finding mating partners (via pheromones) and locating oviposition habitats. [1] Thus, it is the most important sensation for insects. [1] Most important insect behaviors must be timed ...
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 ...
Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
This nongreasy repellent staves off mosquitos for up to 14 hours and ticks, chiggers, flies and fleas for up to eight hours. You can use it on your skin and clothes, and if you hate the strong ...
