Interpretive Summary: Oil palms are native to Southeast Asia, South America, and Western Africa. Oil palms are used in commercial agricultural in the production of palm oil; which is the most widely-produced tropical oil and constitutes 30% of total edible oil production worldwide. Palm oil also can be used to create biodiesel. However, oil palms have heavily suffered from attack by a leaf-miner. For example, most of the areas within the oil palm belt of Nigeria usually experience leaf miner infestation. This attack could cause as much as 60-70% yield loss per year. In collaboration with Nigerian scientists, we examined the chemical components collected separately from samples of male and female leaf miners fed on oil palm leaf and cuticle solvent extracts and found some sex- specific compounds. However, behavioral activities of the identified compounds need to be further examined. Biological information and knowledge of tropical and subtropical insect pests, such as oil palm leaf miner, will help growers to promote semiochemical-based applications to manage insect pest populations on similar crops in the US regions under subtropical climate; including most of California (dry-summer subtropical climate), the low deserts of the Southwest USA (hot arid type), the Gulf Coast and most of Florida (humid subtropical climate). This information will be used by scientists addressing leaf miner control or members of industry interested in palm oil and its applications.

Technical Abstract: To elucidate the characterization of probable pheromone chemical compounds in Coelaenomenodera elaeidis Mlk., volatile samples were collected and subjected to gas chromatographic-mass spectrometric analyses. These compounds were contained in active fractions: Butylated hydroxytoluene (C15H24O); 4, 4’ (P-phenylene) d: isopropyedene diphenol (C24H26O2); Benzeethanol 1, 4-hydroxy (C8H10O2); heptacosane (C27H56); Octacosane (C28H58); Euricacid (C22H42O2); 1-Docosene (C22H44); 1-heptacosanal (C27H56O); Heptacosane (C27H56O); 17-pentatriacontane (C35H70); Benzenoatanol 4-hydroxyl (C8H10O2); Tetracosane (C24H50); Heneicosane (C21H44); Nonacosane; 9, 12-Octadecadienoic acid (C18H32O2); Squalene (C30H50); 1-Docosanol (C22H46O); Cholest-5-en-3-ol (C27H46O); and 9, 12-Octadecadienoic acid (22) (C18H32O2); 2-5 methyl-6-heneicosene-II-one (C22H42O). These compounds need to be further elucidated for their attractive effects on adult males and females of C. elaeidis.
