All the sensory apparatus of the insect are linked with the nervous system, so when you study you can discover the nature of an insect sensetive !!

I think there are many reasons for studying the nervous system of insects from the point of view of both basic and applied knowledge. A valid reason is surely that the understanding of certain physiological functions of the nervous system in insects (as well as in other animals) is necessary for understanding the mechanisms of action of chemical neurotoxic insecticides, therefore for a better knowledge of their efficacy and toxicity. Regards,

I quite agree with Rinaldo Nicoli Aldini  and Bhupendra Kumar reasons on how important to study the nervous system in insects. Also, to understand the coordination of other organs and the systems of insects in relation to their daily activities either beneficiary or injurious to man kind.  

Dear Colleague,

We can also add the following important roles of the NS in electrophysiological studies and behaviour and chemical communication experiments.

Many Insects are now tools for research because it is easy to introduce and follow any insert in insects within a short time. The brain research group is understanding the NS of insects an extrapolating from those experiments. As a matter of fact, there is an annual course on insect neuroscience organized and sponsored by TReND/ IBRO and allies fin Africa to bring such information to the grassroot, it is coordinated by Dr Lucia de Prieto for a group of young and vibrant volunteers. it is a must attend course for a mind as inquisitive as yours. best wishes Aline

Although, Insect neurosciences as a course is okey but I suggest and recommend it for postgraduate students' of Entomology. More so, Insect Physiology is an advance course for 300L or 400L students of entomology and any other animal related courses. Generally, insects are one of the common laboratory animals used for laboratory and experimental demonstrations including physiological demonstrations. Hence, any aspect of insect's anatomy and physiology can be studied.
