Consider Insect+Rod a system, Insect may apply force on Rod to accelerate or decelerate to maintain its speed but that will be an internal force and will have equal and opposite reaction from the rod. As Insect should be accelerating if stationary but as its velocity with respect to ground is constant, which means its applying force in downward direction to decelerate to maintain same speed and the rod is pushing him in upward direction. Therefore net force on rod is due to its weight and Force applied by insect, both in downward direction and therefore acceleration will be more than

Equality is a feeling of emotional well being,why do I say so? Equality is integral in every domain of life : political equality,social equality, economic equality and it goes on. One is said to be politically equal to others,if has the right to vote and participate in elections. Same goes for social equality. Economic equality is another thing,it depends on wealth, which is variable in our life. Everyone seeks for equality, though only some achieve it.
