Humans are fairly new on the planet compared to insects and they are still learning about them and how to live with them. The University of Wisconsin Department of Entomology is making a study on insect biology and their effect on the ecology
Honey bees are the most important insect to life without them there would be no crops. They are intelligent and have a complex communication system. They produce honey, which is a whole food, beeswax used by humans as an ointment, and pollen that humans use as a food supplement. Beekeepers are hired out by farmers throughout the country to pollinate their fields.
Silk worms have been used by man for millennia. It is the larva of the Bombyx mori, a moth originating in Asia. Because it eats only mulberry leaves it is now extinct in the wild. They are raised from eggs in captivity and when the caterpillar spins its cocoon it is unraveled for the silk.
Insects help in the development of medicines, research for diseases and mechanics.
Many insects pose a problem for man, locusts destroy corps, mosquitoes transmit malaria and ticks carry lime disease. They often spread diseases from one person to another or from animal to animal. Horseflies and deerflies carrying equine infectious anemia from horse to horse.
The human/insect equation is complex and though man has dealt with the situation from the time of existence it is a relatively new concept.
