Semiochemical Parsimony in the Arthropoda
Annual Review of Entomology, 1996A wide variety of arthropods have adapted their own semiochemicals to subserve multiple functions in diverse contexts. Semiochemicals, the pheromones and allomones, have been detected in arthropod species in six orders, and it has been clearly established that these compounds are used with great parsimony.

Semiochemicals modulating bed bug behaviour
Current Opinion in Insect ScienceThe common bed bug, Cimex lectularius (Cimicidae, Hemiptera), is obligate haematophagous and can carry pathogens but is not known to transmit diseases to humans in natural settings. Bed bugs are activated and guided by semiochemicals and heat by potential hosts, as well as by an aggregation pheromone when searching for food and home.

Insect semiochemicals and communication
1998The Aurelians take this Moth by Sembling; their manner is, to go out with a live Hen in a Box which is covered down with Gauze or Crape; when they are come to the Appointed place … they set the Box upon the Ground, and stand ready with their Nets; the Cocks will quickly come and attempt to get at the hen.

Females of several species of mealybugs produce pheromones which attract the males. Abdominal glands were suspected to be the source of pheromones in various species. Most of the mealybug pheromones are carboxyl esters of monoterpene alcohols and racemic mixtures were also observed to be effective than enantiomers.

As the chemical ecology of insect pests slowly becomes unravelled, new opportunities have arisen to exploit semiochemicals in different ways in order to achieve the goal of managing insect pest problems. The semiochemicals used often differ substantially both in chemical structure and in biological function from lepidopteran sex pheromones.

Ultramicrochemistry of insect semiochemicals
Mikrochimica Acta, 1998Chemical ecology of the Insecta comprises an invisible environment where semiochemicals are the principal factors regulating the mating and host-selection of the one million or more species. Biologically effective concentrations of these semiochemicals range from 10−10 to 10−3 μg at the insect antennal receptors. These levels are virtually undetectable
