Electron grain probe insect counter

Epsky, N.D. and Shuman, D. 2001. Laboratory evaluation of an improved electronic grain probe insect counter. J. Stored Prod. Res. 37, 187-197. 

Electronic grain probe Improvements have been made in probe trap techniques to automate the detection procedure. Reports from China and the United States indicate that probe traps fitted with either an infrared beam or piezoelectric sensors can be used for insect detection and monitoring in stored grains (Vick et al., 1991 Wei et al., 1999). Shuman et al. (1996) developed a detection device known as the Electronic Grain Probe Insect Counter (EGPIC), in which an infrared beam sensor has been installed in the probe, which identifies and records the insects as they slip...
