Probe traps are effective in detecting insects in grains but neglected because it is time consuming.

The insect probe trap is not readily available in Nigeria and where available, it is expensive due to foreign exchange rates. In order to develop a locally available and more acceptable insect probe trap for integrated pest management practices during post harvest handling of cowpea (bean), locally sourced materials were used to fabricate a probe trap for monitoring bean weevil (Callosobruchus maculatus). Ambient light source was incorporated into the newly and locally fabricated probe trap as cap window to lure insects into the trap, with traps’ perforation size increased for easy passage of insects that attack stored beans. The fabricated probe trap was evaluated together with a standard (imported) probe trap in order to ascertain their difference in performance. Treatments (trap types) were repeated three times, in three different insect densities (3, 7 and 15 insects per kg respectively) artificially infested into 10 kg cowpea grains contained in plastic storage buckets and traps were inspected every 24 hours for five days. The locally fabricated probe trap was also evaluated in 100 kg cowpea sample contained in sack bags to determine the effect of grain volume on the performance of the trap. Data collected were subjected to analysis of variance (ANOVA) and means were separated using Students Newman Keuls test (SNK) at 5 % confidence level. Results showed that the fabricated trap is improved in early detection of the insects, with management thresholds determined for bean weevil controls during post harvest. Recommendation is that the modified probe trap be commercialized in order to make it readily available to the users.
