Author Description

Excerpt from Entomological News, 1960, Vol. 71 The worker caste individual in the fungus-growers, as is normal among ants, is a female which has reduced reproductive organs, a smaller thorax without wings or sutures for them and other morphological differences. In colonies deprived of the functional female (the queen) the ovaries of one or more work ers may form viable eggs that develop into males, again a com mon ant pattern. It is frequently observed that the females among ants are more durable than the worker and survive unfavorable conditions longer. New-colonies usually start from isolated females that leave the parental nest and dig into the soil to form a new nest in which eggs are laid and to which food may be brought to the subsequent larvae. While these differences between the queen and the worker are Obvious, a direct study of the contrasting behavioral pat terns of the two castes when confronted with a novel situation is not so often made. Following is an account of an experiment that supports the belief that the worker differs from the female in the reduction of her instincts.
