Abstract

Grizzly ELS 2500/8 blower-vac was remodeled for arthropod suction sampling and possibly as a non-chemical pest management tool using readily available materials. With an installed intake nozzle (area 0.0020 m2), the modified sampler was used in conjunction with a sampling enclosure (area 0.0707 m2) for sampling arthropods associated with watermelon across 20 samples with 6 sub-samples each using 120 and 20 seconds sampling duration, respectively. Results indicated that overall, 427 individuals were collected across 10 arthropod orders and that about ¾ of the samples were extracted within the 1st sub-sampling duration. Overall, the efficiency and effectiveness of the modified machine were attributed to its lightweight, smaller intake nozzle diameter, high proportion of arthropods extracted vis-à-vis sampling duration, and easier constructability vis-à-vis previously reported ones. Additionally, cost implication was cheaper than the cost of many conventional suction samplers, particularly, the popular Dietrick vacuum (D-vac). Hence, it is recommended for use as a suitable alternative, particularly, by researchers and farmers in developing countries who may not be able to afford other more expensive suction machines.
