The Challenges of Gardening in the Dark

Termites, spending ⁤their lives in the darkness of their mounds and tunnels, lack functional eyesight. However,this doesn’t‍ hinder their ability to cultivate a crucial food source: fungus. According⁢ to researcher Raychoudhury, termites compensate for their blindness through⁣ highly developed senses of smell and touch, using⁤ these to identify and remove unwanted organisms from⁣ their gardens.”They can detect the environment based on advanced olfactory⁢ reception and touch, and I think this is ​what ⁢they use to identify the weeds in ⁢their gardens,” Raychoudhury explains.

To understand how termites respond to weed infestations,RaychoudhuryS team conducted experiments using Odontotermes obesus termites.

Experimental Setup: A Controlled weed​ invasion

The research team created a controlled environment using sterilized soil from termite mounds placed in⁢ glass Petri dishes. Each dish contained two fungus combs. One comb served as a control – a healthy,uninfected sample of⁤ Termitomyces ⁤ fungus,providing the termites wiht a necessary food source. “Besides acting⁣ as a control, it was also there to make sure the termites have the food because it is very⁢ hard for them to survive outside their mounds,” Raychoudhury stated.‍ The second comb was deliberately contaminated with Pseudoxylaria, a filamentous fungus known to compete with​ and overtake Termitomyces in termite ​colonies.
