When feeding on rolled oats, male square-necked grain beetles,Cathartus quadricollis (Guér.), produced the aggregation pheromone (3R,6E)-7-methyl-6-nonen-3-yl acetate, for which the trival name “quadrilure” is proposed. The pheromone was highly attractive to both sexes in a two-choice, pitfall olfactometer modified to retain responding beetles by placing a food stimulus (an oat flake) in the glass vials containing the experimental and control stimuli. TheS enantiomer of the pheromone was… 

Semiochemical-Mediated Flight Responses of Sap Beetle Vectors of Oak Wilt, Ceratocystis fagacearum

Flight responses of this beetle were similar in Illinois and Minnesota populations, and both sexes of the beetle responded synergistically to a combination of the three-component pheromone and fermenting whole-wheat bread dough.

1-Octen-3-ol, attractive semiochemical for foreign grain beetle,Ahasverus advena (Waltl) (Coleoptera: Cucujidae)

L Laboratory bioassays in a two-choice, pitfall olfactometer modified to retain responding beetles revealed that 1-octen-3-ol serves as an aggregation pheromone for A. advena.

Fungal volatiles: Semiochemicals for stored-product beetles (Coleoptera: Cucujidae)

Responses by five species of cucujid grain beetles (mixed-sex adults) to various volatiles were assessed by means of a two-choice, pitfall olfactometer by finding racemic and chiral 1-octen-3-ols were strong attractants for Cryptolestes ferrugineus (Stephens) and 3-methylbutanol enhanced positive response to their respective cucujolide aggregation pheromones.

1-Octen-3-ol is Repellent to Lps pini (Coleoptera: Curculionidae: Scolytinae) in the Midwestern United States

The testing of 1-octen-3-ol in combination with ipsdienol suggests that the compound is potentially repellent and interrupts the response of beetles to their aggregation pheromone, and is consistent with previous reports of its inhibition of aggregation behaviour in other bark beetles.

Pheromone-mediated aggregation in nonsocial arthropods: an evolutionary ecological perspective.

It is shown that aggregative behavior by individuals through the use of pheromones can profoundly affect ecological interactions and advocate further evolutionary and ecological investigations of phersomone-mediated aggregation.

Aggregation pheromones of the grain beetle,cryptolestes turcicus (Coleoptera: Cucujidae)

Two biologically active macrolides were isolated from Porapak Q-captured beetle and frass volatiles ofCryptolestes turcicus and identified spectroscopically as (Z,Z)-5,8-tetradecadien-13-olide (I) and (Z), which reported the first reported instance of enantiomeric synergism in the Cucujidae.

Both sexes responded to the odor of beetle populations of mixed sex as well as to the scent of males, indicating that males produce a true population aggregation pheromone.
