Computer-based image analysis to estimate the area of sticky trap occupied or contaminated by pests.

Original language description

Traps are tools frequently used to monitor and control pests. The instant active area of a trap (the instantly available area of a trap that is able to capture a pest) is a determinant of trap efficacy. Therefore, we de-veloped a technique of computer image analysis of digital photography to evaluate the instant active trap area, occupancy (area of insect bodies captured on the trap) and contamination (area of filth left by pests on the trap, such as wing-scales or faeces) of it. This study illustratesits use with two types of sticky traps applied to moni-tor the German cockroach, Blattella germanica, and the Mediterranean flour moth, Ephestia kuehniella. We found that moths decreased the capacity of the sticky surface more than cockroaches because ofits contamination by wing-scales. The sticky trap area covered by wing-scales was nearly as large as the area occupied by moth bodies. Cockroaches contaminated the sticky surface by their faeces but the contaminated area was less than 2%
