Abstract : Studies were conducted to upgrade and modify the acoustical system to detect insect larvae in post-harvest commodities described by J.C. Webb et al. in 1988. The system can detect one-day-old fruit fly larvae in grapefruit, mangoes and other similar fruit, and lepidopterous and coleopterous larvae in individual kernels as well as bulk grain. The detectors have been modified so that they can be adjusted to accept fruit of various sizes and shapes. A computer system and software have been developed to monitor the feeding activity of the immature insect for its complete life cycle.
