The Growth of Tribolium castaneum (Herbst) and Lasioderma serricorne (Fabricius) on Feed Media Dosed with Flavour Volatiles Found in Dry Cocoa Beans

Abstract

Acetophenone, ethyl butyrate and 2-phenyl ethanol were used as additives to media on which Tribolium castaneum (Herbst) and Lasioderma serricorne (Fabricius) were cultured for 65 days. Acetophenone and ethyl butyrate had a positive impact on the weight and multiplication of the insects. The weight and rate of multiplication was higher in feed media containing acetophenone alone. The amount of the flavour volatiles added was high enough to deter the Lasioderma from feeding well, which affected their growth. This attraction to specific flavour volatiles in some stored products could be used in the formulation of effective control measures for insect pests.

Differentiation of Chocolates According to the Cocoa’s Geographical Origin Using Chemometrics

“…Even if the compounds responsible for the characteristic aroma of cocoa have been widely studied over the past century, these compounds are still of interest in view of various papers and studies published more recently − . The compounds that give cocoa and chocolate their flavors are molecules such as pyrazines, aldehydes (cocoa aroma, nut), esters (fruity aroma), and phenolic compounds (astringent property).…”

Analysis of volatiles from feces of released Przewalski’s horse (Equus przewalskii) in Gasterophilus pecorum (Diptera: Gasterophilidae) spawning habitat

“…Jonfia-Essien et al . 36 , 37 found that acetophenone had a positive effect on the growth and development of red flour beetle ( Tribolium castaneum Herbst) and cigarette beetle ( Lasioderma serricorne Fabricius), and it was also an active substance stimulating antennae of red flour beetle. Jeanbourquin and Guerin 20 reported that EAG response of stable fly to acetophenone from equine feces was stronger than that from cattle feces, in which low levels of acetophenone were detected.…”

Traveling across Life Sciences with Acetophenone—A Simple Ketone That Has Special Multipurpose Missions

“…Interestingly, these aggressive tree-killing bark beetles can rapidly colonize their host by producing an aggregation pheromone, which can be regulated by acetophenone-based multicomponent blends. It is interesting to note that other pest beetles are addicted to acetophenone, which had a positive impact on the weight and multiplication of the red flour beetle ( Tribolium castaneum ), a worldwide pest of stored products, and the tobacco beetle ( Lasioderma serricorne ), one of the most widespread and damaging pests for the tobacco industry, when they were treated with acetophenone-containing cultures that deter the beetles from feeding well, which affected their growth, and thus, acetophenone exhibits antifeedant properties in this case [ 47 ]. Acetophenone is also involved in complex interactions between fungal symbionts of the ambrosia beetle Platypus cylindrus and the cork oak ( Quercus suber ), an interesting plant that is the primary source of cork for wine bottle stoppers.…”
