 traps were evaluated. Each treatment (trap) was repeated three times and in three different insect population densities (3 insects per kg, 7 insects per kg and 15 insects per kg) artificially infested into 10 kg cowpea grains contained in plastic storage buckets. Traps were inspected every 24 hours for five days, data collected were subjected to ANOVA and means were separated using Students Newman Keuls test at 5% confidence level. Ambient light source was the best mean in probe trap catch of <i>C. maculatus</i> infesting stored cowpea. Therefore, ambient light source should be incorporated into probe traps for early detection and management of cowpea weevils.&picture=http://www.aascit.org/aascit/decorators/img/journal/903.jpg)

The unlighted probe traps are effective in detecting cowpea weevil in stored cowpea but due to time constraint, its use has been neglected. In order to improve on the performance of this important Integrated Pest Management tool for early detection and management of C. maculatus, investigations were carried out to search for means that can improve the performance of the trap and light was reviewed to be a workable means to giving reliably early indications of insects that move readily in grains for necessary control measures to be initiated. Seven different probe traps comprising of six different color lighted probe traps and a control (unlighted) traps were evaluated. Each treatment (trap) was repeated three times and in three different insect population densities (3 insects per kg, 7 insects per kg and 15 insects per kg) artificially infested into 10 kg cowpea grains contained in plastic storage buckets. Traps were inspected every 24 hours for five days, data collected were subjected to ANOVA and means were separated using Students Newman Keuls test at 5% confidence level. Ambient light source was the best mean in probe trap catch of C. maculatus infesting stored cowpea. Therefore, ambient light source should be incorporated into probe traps for early detection and management of cowpea weevils.
