Callosbruchus maculatus is a warehouse pest that attack many various of nuts. One of the food preservation techniques from the threat of pests in Indonesia is the use of chemical pesticides and fumigants. However, it can interfere the human health, contaminate the environment and non-target organisms. The aims of this study is to compare the extraction method of dimethyloctane dioic acid and analyze the effectiveness of dimethyloctane dioic acid nanoparticles in controlling C. maculatus. The research method consisted of sample preparation, dimethyloctane dioic acid extract, like-dislike test and GC-MS analysis. The results showed that compounds extracted using the sampling headspace aeration method were more effective and right on terget than body extract method. The compound of dimethyloctane dioic acid from body is very high evaporation rate than headspace aeration. The Independent Sample T Test gave significant results between C. maculatus response to headspace aeration and body extract method. © Published under licence by IOP Publishing Ltd.
