how to live in greater biological harmony with the planet
. One thing humans already share with several species of insects is a practice known as “eusociality”. This is the highest form of social behaviour.
Why are entomologists important?
Professional entomologists contribute to the betterment of humankind by
detecting the role of insects in the spread of disease
and discovering ways of protecting food and fiber crops, and livestock from being damaged. They study the way beneficial insects contribute to the well being of humans, animals, and plants.
What is the importance of insects in agriculture?
Insects and other arthropods serve in a number of beneficial ecological roles (sometimes called ecosystem services) in agricultural and natural systems: As decomposers,
helping to mediate the breakdown of plant and other organic residues
, and the mineralization and recycling of plant nutrients from those residues.

Without insects, our lives would be vastly different.
Insects pollinate many of our fruits, flowers
