entomologist Archives - DOES GOD EXIST? TODAY

We get many interesting responses to our daily articles on this website. Recently, several people responded to our emphasis on the value of insects. Bugs can indeed bother us. Some bite or sting, while others eat our vegetation encroaching on our food supply. Despite those things, we have pointed out that entomologists tell us that insects are beneficial.

Akito Kawahara, a curator at the Florida Museum of Natural History, said that most people are unaware of the value of insects. Kawahara points out that insects annually contribute 70 billion dollars to the U.S. economy by their roles in pollination and waste disposal processing. Everyone knows that insects are involved in pollinating flowering plants, but they may not realize that insects are the linchpins, holding together almost all land-based ecosystems. Also, insects provide food sources for birds, bats, freshwater fish, and numerous land animals.

Not realizing the value of insects, humans have done much to eradicate them. We have reduced their habitat, used massive amounts of pesticides, and made them victims of pollution. Sometimes, we have brought in invasive species of animals and plants that harm the ecosystems. We have also done things that accelerate climate change. The National Academy of Sciences suggests initiating a campaign to encourage people to avoid using bug zappers, practice insect conservation, do less mowing, and use insect-friendly soaps and sealants.

God set up a working system that has produced a high standard of living for thousands of years. We are threatening to unbalance the system by our capacity for high tech devices and materials. Sometimes insect populations get out of control and damage human resources, such as the locust invasions of recent years. It is often human interference with the natural controlling agents that have caused the insect infestations. People need to be aware of the value of insects to life on this planet.

Ant Farmers at Work — Leafcutter Ants at Work Taking Leaf Cuttings to the Colony

We commonly think of animals as opportunists. They find their food and eat it or store it for future eating. One of the characteristics of humans that distinguishes us from the rest of the animal kingdom is that we prepare an environment that produces our food. Farmers plant seeds and tend the crops by fertilizing, protecting from threats, and watering when necessary. They also make arrangements for future crops. Entomologists are finding more and more cases where insects do these same things. For example, ant farmers work together to produce their food.

In Fiji, a plant called Squamellaria grows in a cluster with jelly-bean shaped bubbles inside. The opening into the clusters is just the right size for the Philidris nagasau ant to get into the bubbles. As the bubbles send out shoots, the ants defecate inside the cluster, fertilizing the plant. When the plant blooms, the ants eat the nectar it produces. The ants then plant the seeds where new clusters can grow.

Another family of ant farmers is the Atta genus. In their farms, they grow a fungus species that they nourish with leaf cuttings. After cutting off leaf sections, worker ants carry them back to the colony. As the workers transport the leaf cuttings, others ride on the leaves to protect against a parasitic fly species. You might call that pesticide.

At the colony, other ants pulverize and defecate on the leaves to make them ready to nourish the fungi. The ants can’t eat the leaves, but the fungi are their food, and only one fungus species is edible. If another fungus species develops, the ants produce a toxin, which destroys only the invading fungus. This is herbicide use at its best. The Atta ants inspect the fungus several times a day, tending it carefully. The system is so efficient that one Atta nest can grow enough fungus food to feed seven-million resident ants. In the process, the ant colony produces fertile soil that promotes plant growth.

If you saw the 1994 Disney animated Lion King movie, you saw Atta ant farmers at work. Remember that fungi are not photosynthetic. No sunlight is needed for Atta ants to grow their food. They simply carry in the nutrients for the fungi to grow, and then they eat the fungi. We do the same thing with much of our meat, providing plant material for chickens or pigs to eat, and then eating the animals that we fed. In the case of the ants, they eat only one food, which simplifies farming enormously.

We know it takes incredible planning and design to manage a farm. No chance process produces most of the foods we eat. It requires meticulous planning and careful application of fertilizers, pesticides, and herbicides. As scientists study insect farming, they see a design that is carefully and intricately produced.

Data on the ant farmers came from Science News, April 25, 2020, pages 16-20. The subtitle of the article is, “Could our agricultural role models have six legs?” This reminds us of the challenge in Proverbs 6:6-8: “Go to the ant … consider her ways, and be wise. She has no guide, overseer or ruler but provides her food in the summer and gathers her food in harvest.” The title of the article is “The First Farmers.” We might amend that to be “God’s First Farmers.”
