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.

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.

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 ...

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.

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.

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.
