Insecticide activity from mangrove endophytic fungus isolate against larvae of fruit flies (Drosophila melanogaster)

Abstract

The fruit fly Drosophila melanogaster (D. melanogaster) is one of the important pests for fruit and vegetable plants. However, pest control efforts are highly dependent on synthetic insecticides. This study aimed to determine the potential of mangrove endophytic fungi as bioinsecticides for D. melanogaster and to determine the insecticidal activity of secondary metabolites of mangrove endophytic fungi against D. melanogaster larvae. The study was conducted on five types of fungi extract isolated from R. mucronata, namely E. nidulans (BPPTCC 6035), E. nidulans (BPPTCC 6038), A. tamarii (BPPTCC 6037), A. versicolor (BPPTCC 6039), and A. oryzae (BPPTCC 6036) in 500 and 1000 ppm. The results showed that the A. versicolor (BPPTCC 6039) extract was the most toxic. Tukey’s HSD test showed that the A. versicolor (BPPTCC 6039) extract was most effectively used as a bioinsecticide for D. melanogaster larvae. All extracts do not have antifeedant compounds and showed activity to inhibit larvae growth. Therefore, in this study, the A. versicolor (BPPTCC 6039) extract had the most significant potential as a bioinsecticide for D. melanogaster larvae.
