**1. Introduction**

Insects play a vital role in both natural and man-made settings. They perform critical and functional roles in ensuring the delivery of numerous ecosystem services that are critical for human life in areas such as agriculture, tourism, natural resource utilization etc. [1, 2]. Scientific investigations have shown that insect populations have been declining globally for decades [3]. Environmental scientists as well as the press, non-governmental organizations, and policymakers, have been alerted to the eminence reports of impoverished insect faunas from Europe and around the world [4]. West Africa countries are afro-tropical with a diverse flora and fauna, as do other tropical countries throughout the world. The tropics, which are home to over 70% of world biodiversity, are also a treasure trove of insect diversity, which is thought to be comparable to the region's plant richness [5].
