INTRODUCTION:
Approximately 80% of animal species on earth are insects, 99% are invertebrates. They are the pollinators, undertakers, leaf litter sweepers, garbage collectors, soil conditioners and natural fertilizer producers of nature.

THEIR IMPORTANCE
Humans depend on natural ecosystems of water, oxygen, sources of food and building materials, therefore the activities of insects in the following areas are of importance:-

1. POLLINATION: Flower color, shape and scent has evolved to attract their insect pollinators; e.g. bumble, solitary and squash bees, beetles, butterflies, flies and ants.

2. DECOMPOSITION & NUTRIENT CYCLING: Insects and their arthropod relatives are responsible for much of the nutrient cycling, conditioning and aeration of the soil; e.g. dung beetles, flies, carrion beetles, millipedes, cockroaches, & termites.

3. FOOD FOR WILDLIFE AND IN MEDICINE: Many different kinds of animals eat insects making them essential parts of the food chain; e.g.: amphibians, reptiles, birds, fish, arthropods and other invertebrates, mammals (primates including humans).

4. PREDATORS, PARASITES & PARASITOIDS: Some insects provide natural population control of other insects, arthropods and vertebrates; e.g.: ladybird beetles, lacewings, parasite wasps

It simply means that when the owner of the farm fails to apprehend the thief in time, the thief will apprehend the owner and label him the thief. The proverbial encounter between the farm owner and the thief aptly explains the drama that came to a climax this past week, precisely on Thursday, February 22nd 2014 with the suspension of the Governor of the Central Bank of Nigeria, Sanusi Lamido Sanusi on grounds of “financial recklessness and misconduct”.

The stage was set on September 25 2013 when Sanusi Lamido wrote to President Goodluck Jonathan accusing the Nigerian National petroleum Corporation (NNPC) of failure to repatriate $49.8 billion (about 8 trillion naira) into the Federation Account between January 2012 and July 2013. In essence, the CBN Governor had accused the NNPC of failure to account for 76% of the total value of crude oil liftings within the given period. The CBN Governor then recommended to Mr. President the following:
