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.

Chemical communication in cucujid grain beetles

Males of five sympatric species of economically damaging cucujid grain beetles,Cryptolestes ferrugineus (Stephens),C. pusillus (Schönhen),C. turcicus (Grouvelle),Oryzaephilus mercator (Fauvel), andO.

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.

Olfactory and Feeding Preferences of Cryptorhynchus lapathi L. (Coleoptera: Curculionidae) Among Hybrid Clones and Natural Poplars

Abstract Hybrid poplar clones show varying levels of attack by Cryptorhynchus lapathi (L.), a wood-boring weevil. We studied differences in olfactory and feeding behavior among four different hybrid

Feeding habits, movement, and reproduction of the predatory flat bark beetles Cathartus quadricollis (Coleoptera: Silvanidae) and Leptophloeus sp. (Coleoptera: Laemophloeidae) in Hawaii coffee and macadamia nut

Hawaii has a multitude of scolytine (Coleoptera: Curculionidae: Scolitinae) pests including Hypothenemus hampei , coffee berry borer, which is apest of coffee, Hypothenemus obscurus, tropical nut

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.

Isolation and identification of two macrolide pheromones from the frass ofCryptolestes ferrugineus (Coleoptera: Cucujidae)

Two synergistic macrolide aggregation pheromones were isolated from Porapak Q-trapped volatiles obtained from the frass ofCryptolestes ferrugineus (Stephens) and given the trivial names ferrulactone I and II.

Olfactory response to beetle-produced volatiles and host-food attractants by Oryzaephilus surinamensis and O. mercator

Male and female beetles of both species were attracted to pentane extracts of Porapak Q trapped volatiles from beetles, frass, rolled oats, and brewer's yeast over a wide range of stimulus concentrations.

Evidence for a male-produced aggregation pheromone in the rice weevil.

A male-produced aggregation pheromone in Sitophilus oryzae (L.) was detected in two closed laboratory bioassay systems. This pheromone proved to be equally attractive to virgin and mated 6- to

Determination of chirality of alcohol or latent alcohol semiochemicals in individual insects

The results indicate that considerable variability exists within populations of some insects in the composition of their chiral semiochemicals, whereas others produce substances of constant composition.

Stored Grain Pests.

In India, post-harvest losses caused by unscientific storage, insects, rodents, microorganisms etc., account for about 10 per cent of total food grains. The major economic loss caused by grain
