Abstract:This article mainly compares the similarities and differences between Prima produced by Malaysia Pupuk Alam company and protein bait for Bactrocera dorsalis (Hendel) developed by our research institute. The biological test was used to compare attractive effects, and High Performance Liquid Chromatography with Precolumn Derivatization (AccQ·Tag) was used to analyse the kinds and contents of amino acids. The results showed the attractive effects of Prima and protein bait were similar, and the two protein baits all contained 17 kinds of free amino acids and 18 total amino acids. Prima contained 52.847 6 mg/mL of total amino acids, 5.736 4 mg/mL of free amino acid, and 47.111 2 mg/mL of peptides. The protein bait was consisted of 65.624 3 mg of total amino acids, 6.301 0 mg of free amino acid, 59.323 3 mg of peptides in one milliliter. Besides, the attractive effect of hydrolyzed protein was stronger than before. The results can provide a basis for monitoring protein bait quality on the industrial production.
