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.

Olfactory coding in the perception of semiochemicals
Journal of Chemical Ecology, 1988Information processing in the olfactory pathway underlying the perception of semiochemicals by insects is discussed. Both the chemical message for mates and the message for food consist of blends of chemicals. Olfactory receptors in an insect species are tuned to the detection of those compounds which comprise such chemical messages for that species ...

Semiochemicals via epoxide inversion
Journal of Chemical Ecology, 1996A sequence of reactions is presented for inverting the configurations of both epoxide carbons in 1,2-disubstituted epoxides. As examples, (+)-disparlure was converted to its enantiomer, (-)-disparlure, andexo-endo conversion of a cyclohexene oxide was demonstrated.

Olfactory Semiochemicals of Tephritids
2020Olfactory semiochemicals are volatile chemicals that modify the behavior of tephritids and can be classified as attractants, repellents, stimulants, deterrents and arrestants. Plant kairomones and allomones that influence tephritid behaviors can be both host-plant and non-host-plant in origin.

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.

Pheromones and Other Semiochemicals of the Acari
Annual Review of Entomology, 1985In contrast to the exceptional diversity of semiochemical-regulated behavior in the insects, chemical communication in the Acari is restricted to a few limited roles. These include clustering, mate-finding processes, host- and food-finding processes, and dispersal.

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.

Applied research on semiochemicals at T.N.O.
Agriculture, Ecosystems & Environment, 1988Abstract T.N.O. has been active in pheromone research since the late 1960s. The emphasis was originally on isolation and identification. T.N.O. research resulted in the identification of trail pheromones of termites and an ant, sex pheromones of 7 lepidoptera and a cockroach, the alarm pheromones of several aphids, aggregation pheromones of ...
