Synthesis of 4-(4-Methoxy-Phenyl)-3-Butene-2-on and the Activity Test as a Fruit Flies Atractant

Abstract

4-(4-methoxyphenyl)-3-buten-2-on has been synthesized from p-anisaldehyde and acetone via aldol condensation. The reaction was performed at room temperature under basic condition for 12 hours to give brown solid of product (m.p 64-65 oC) in 66.19 % yield. p-anisaldehyde itself was produced from oxidation of anetol major component of anise oil by the use of potassium permanganate as a oxidator. The structure of the products was analyzed by FTIR, 1H NMR and GC-MS. Activity test of 4-(4-methoxyphenyl)-3-buten-2-on as an attractant was carried out in Sleman with methyl eugenol as a reference. The result showed that 4-(4-methoxyphenyl)-3-buten-2-on was inactive compound as a fruit flies attractant and some of fruit flies, i.e. Bactrocera papayae, B. carambolae, B. umbrosa and B. abdolonginqua was found on the test area. Keywords: 4-(4-metoxy-phenyl)-3-butene-2-on, Bactrocera spp., attractant

Synthesis Edible Film Chitosan/Polyethylene Glycol/ Carboxymethylcellulose with Lemongrass Oils as Insect Ovipositing Repellent

“…It is one of the safest methods for handling pests because it doesn't act as an antagonist for flies. Repellent does not harm the flies, but it makes the host unattractive for flies so that the flies will not lay its egg on fruits or as called Insect Ovipositing Repellent (IOR) [10]. Among the various plasticizers, polyethylene glycol (PEG) is one of the efficient plasticizers used for polymers because of the advantage of a broad range of molecular weights, nontoxic, miscibility, and biodegradability [11][12][13][14].…”
