Solenopsis invicta virus 1 decreases the foraging activity and influences the diet of its host

In the article “Viral infections in fire ants lead to reduced foraging activity and dietary changes” recenty published in Scientific Reports, Hung-Wei Hsu, Ming-Chung Chiu, DeWayne Shoemaker, and Chin-Cheng Scotty Yang reveal that Solenopsis invicta colonies infected with the Solenopsis invicta virus 1 (SINV-1) had a reduced foraging performance, a reduced lipid intake, and a shifted food preference towards carbohydrate-rich food. In this Photoblog contribution, Scotty Yang shares pictures and a video related to this article.
