Dacus dorsalis

Pheromone (sex attractant). Ether extract of the stem, produced equivocal effect on Aspiculuris tetraptera, female and male Dacus dorsalis, male Mediterranean fruit flies, and male and female melon flies " k Pheromone (signaling). Ether extract of the stem, produced equivocal effect on Aspiculuris tetraptera, female and male Dacus dorsalis, male Mediterranean fruit flies, and male and female melon flies " k Phospholipidemic effect. Oil, administered to phospholipids transfer protein knockout (PLTPO)-deficient mice, produced an increase of phospholipids and free cholesterol in the VLDL-LDL region of PLTPO mice. Accumulation of phospholipids and free cholesterol was dramatically increased in PLTPO/HLO mice compared to PLTPO mice. Turnover studies indicated that coconut oil was associated with delayed catabolism of phospholipids and phospho-lipids/free cholesterol-rich particles. Incubation of these particles with hepatocytes of coconut-fed mice produced a reduced removal of phospholipids and free cholesterol by SRBI, even though SRBI protein expression levels were unchanged .

Eugenol has been used as a feedstock in the production of isoeugenol, which is needed in the manufacture of vanillin. Methylation of eugenol yields methyleugenol, which acts as a sex attractant for a certain type of fly (Dacus dorsalis) [7,8]. 

Some entomologists believe that methyleugenol, the attractant for the oriental fruit fly Dacus dorsalis Hendel), is a sex attractant because the chemical attracts only the male and its action is so powerful 89). However, it appears to be a food lure, because the flies avidly devour the chemical 89).
