The synthesis of insect sex phermones

trans-8, trans-10-Dodecadien-1-ol is a sex attractant of the codling moth, Laspeyresia pomonella. Antennal responses (electroantennograms) to a series of monounsaturated compounds were used in determining the location and configuration of the two double bonds. The synthetic compound is very attractive to male codling moths in the field.

Management of Insect Pests with Semiochemicals

Reciprocal field tests of attraction between populations of Ips pini (Say) from California, Idaho, and New York disclosed geographic variation in pheromone systems These differences reside both in pheromone production and reception However, it is unknown whether variation in the pheromone bouquets is qualitative, quantitative, or bothIn New York, both sexes responded in higher numbers to their own pheromone than that produced by California or Idaho males In California, beetles of both sexes discriminated against New York, but in Idaho only females made this distinction In both California and Idaho, the local population showed a slight preference for the pheromone produced by Idaho males over that produced by California malesThe predator Enoclerus lecontei (Wolc) demonstrated a four-fold preference for attractants produced by males from New York over those produced by beetles from California and Idaho The parasitoid Tomicobia tibialis Ashmead showed the opposite trendThere is no evidence that geographic variation in the pheromones produced by I pini is sufficient to enforce breeding isolation between adjacent populations However, these results dramatize the necessity of considering pheromonal variability in programs applying pheromones for the survey and control of widely distributed pests

Pheromones of ips pini (coleoptera: scolytidae): variation in response among three populations

Female moths of different species but belonging to the same subfamily produce an identical compound as their sex pheromone. The sex pheromone of the almond moth, Cadra cautella (Walker), and the Indian meal moth, Plodia interpunctella (Hubner), has been isolated and identified as cis-9, trans-12-tetradecadienyl acetate.
