How Do Violent Conflicts Between Termites Influence Their Lifespans?
Termites are relatively understudied insects within the field of entomology. This is somewhat surprising given the significant economic costs associated with termite structural damage. Termites in the United States alone cause billions of dollars each year in damages. You would think that a greater scientific understanding of termite behavior would be desired in order to more effectively combat these destructive insects. However, termites are regarded with widespread disinterest, as there are many other fascinating insects in the world that capture the curiosity of academics and scientists. Although termites may not be the most interesting of insects, the fact that termite queens can survive for a longer amount of time than any other insect species is worthy of attention. A recent study examined how intercolony conflict between termites can influence the lifespan of queen and king termites. Additionally, the study authors were able to determine how warring termite colonies resolve conflict after the death of each side’s royal pairs.
For the study, researchers collected Z. n. nevadensis termite species from the wild. These termites spend much of their lives in trees where encounters between different colonies are common. The researchers placed two different colonies into artificial arboreal conditions in order to gauge intercolony behavior. Since termite colonies vary drastically in age, encounters between two colonies of the same age is not the norm. When two termite colonies of the same age made contact in the lab, violence soon followed. The subsequent conflict resulted in the deaths of a royal pair from one colony while the royal pair from the other colony survived. The remaining workers and soldiers from the defeated colony were eventually absorbed into the victorious colony. When colonies of different ages were introduced, the older colonies killed off the younger colonies entirely, leaving the royal pair and all of their worker and soldier offspring dead. It was also found that termite queens would die unusually young if they had survived previous intercolony conflicts. The reason for this is not clear, but researchers believe that the queens may have died young due to injuries sustained during previous skirmishes. In general, colonies that are relatively large will live for a longer period of time than smaller colonies.
Have you ever seen a termite queen in a Zoo or even in the wild?
