“…The mymrecophagic jumping spider Habrocestum pulex also uses 6-methyl-5-hepten-2-one as a foraging cue, which may be released by their ant prey (Clark & Jackson, 2000). An attracting function of 6-methyl-5-hepten-2-one has been documented in a range of insects, including as a mating aggregation pheromone in several African malaria vector mosquito species (Mozūraitis et al, 2020) and as a male-produced aggregation pheromone of the curculionid beetle Acrotomopus atropunctellus (Rodríguez et al, 2016). It is also found in plant odours (Knudsen, 2006) and its presence in intact peach shoots is attractive to the oriental fruit moth, Cydia molesta (Lu & Qiao, 2020).…”

Alarm signals are a common feature of social species and are thought to be a means of alerting others to an external threat (e.g., Gill & Bierema, 2013;Kaplan, 2014;Townsend & Manser, 2013). Among cooperatively breeding mammals and birds, individuals may give an alarm call in the presence of natural enemies, thereby allowing others to take defensive action, ranging from hiding to mobbing the intruder (Caro, 2005). The different responses to alarm calls indicate that they can convey specific information about the nature of the threat, including the kind and proximity of the predator, allowing the receivers to respond appropriately. For example, the alarm calls of vervet monkeys Chlorocebus pygerythrus differ according to the threat: avian predators elicit "eagle" calls and receivers then hide in bushes, while receivers move into trees when they hear "leopard" calls (Seyfarth et al., 1980). Thus, alarm calls are thought to have "functional reference" (Evans, 1997;Macedonia & Evans, 1993), where the receivers react to the alarm calls similarly to how they would react to the threat itself (

Comparative analysis of volatile compound profiles of propolis from different provenances

2018

BACKGROUND: Propolis is a complex mixture that honey bees produce from the exudates of various plants and presents many medicinal properties. Its chemical composition varies according to the phytogeography characteristics of each region, among others. The aim of this study was to identify and characterize the volatile organic compounds (VOCs) present in Venezuelan propolis and compare with reference samples such as Brazilian and Argentinian propolis. RESULTS:A total of 90 VOCs were identified in a series of propolis samples using both solid-phase microextraction and dynamic headspace (DHS), both coupled to a gas chromatograph-electron ionization mass spectrometer. In the case of Venezuelan propolis, sesquiterpenes, esters, aromatic compounds, and aliphatic hydrocarbons were identified. Limonene was found only in Venezuelan samples, this being the first time it has been identified in samples from this country. In the case of green propolis, -caryophyllene and nerolidol were the major compounds. As for the Argentinian samples, prenyl acetate, benzyl acetate, and 2-phenylethyl acetate were detected only in these samples.CONCLUSIONS: Possible chemical markers of natural sources such as limonene were detected using DHS extraction. Several compounds have also been identified for the first time in Venezuelan propolis. Cluster analysis allowed the relating of the propolis VOCs profile to their provenance.

Male-Produced Aggregation Pheromone of Coffee Bean Weevil, Araecerus fasciculatus

et al. 2017

The coffee bean weevil (CBW), Araecerus fasciculatus (De Geer, 1775), is a cosmopolitan stored-product pest, especially in tropical and subtropical areas. Previous reports showed evidence for aggregation behavior of CBW and this study aimed to identify and evaluate the aggregation pheromone of this pest. Whole-body solvent extractions were analyzed by coupled gas chromatography-mass spectrometry and comparison of male and female extracts showed a male-specific compound which was identified as squalene, 2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosahexaene. This compound was shown to attract male and female CBW in Y-tube olfactometer and storage trap assays. The longevity of septum lures was also evaluated in a warehouse. Squalene could be useful in monitoring and controlling this pest.
