K. Naskar, S. K. Raut


The ants Pheidole roberti were offered eight different types of foods having different weights and sizes, in their foraging area to note their food carrying strategy. It is revealed that the ants P. roberti are habituated to apply any of the four food carrying strategies viz. lifting strategy, pulling strategy, pushing strategy, and group strategy through the application of pushing and pulling strategy in a coordinated way. It is also well evident that the application of food carrying technique is very much dependent on the weight and/or size of food particles to be transported to the nest. Depending upon the weight/size of the food article P. roberti are accustomed to modify the food carrying technique accordingly, to ensure food transportation success.
