Abstract

Crop cabbage worm (Crocidolomia pavonana) is one of the pests that has a bad effect on the cabbage production in Indonesia. One of the efforts that has been applied to control this pest is by using bayrusil. However, the bayrusil can cause negative effects such as poisoning and environmentally polluting effects. To prevent the undesired effects, it has been developed the use of environmentally friendly insecticide and one of them is the use of insecticidal peptide. Tripsin-modulating oostatic factor (TMOF) and ist analogues is one of the peptides that has an insecticidal activity. The aim of this research is to synthesise a linear tetrapeptide (DPAP) an analogues of TMOF and to test insecticidal activities against crop cabbage worm.  A DPAP has been synthesised by Solid Phase Peptide Synthesis on 2-chlorotrytil chloride resin. Fmoc strategy was applied on the synthesis and a combination DIC/Oxime was employed in the coupling reaction.The tetrapeptidyl resin was cleaved by TFA:water:EDT (90:5:5). The peptide was purified by reverse-phase column chromatography and characterized by TOF ES-MS spectroscopy. A linear peptide was biologically tested towards the C. pavonana, showing percentage of mortality values at 1000 ppm.
