Summary: Queens of the pharaoh's ant Monomorium pharaonis (L.), like several other ant species, feed on larval secretions as their main nourishment and their fecundity is positively correlated with the number of large larvae present in the nest. The surplus of secretions produced by larvae is stored in a temporary caste of replete workers, which comprises young workers who remain in the nest and store liquid nourishment. Repletes are characterised by a conspicuously large gaster, caused by… 

Dietary influence on larval storage proteins of the pharaoh's ant, Monomorium pharaonis (Hymenoptera: Formicidae)

This preliminary study reported the influence of dietary protein levels on larval storage proteins of the Pharaoh's ant, Monomorium pharaonis, and found that there appeared to be variation in protein storages among different larval stages.

Functional morphology of the postpharyngeal gland of queens and workers of the ant Monomorium pharaonis (L.)

The PPG serves different purposes in pharaoh's ants: it is likely that the PPG of workers and virgin queens is used to feed larvae, and in mated queens the gland probably plays a role in providing the queen with nutritious oils for egg production.

Food storage and morphological divergence between worker and soldier castes in a subterranean myrmicine ant, Carebara perpusilla

Using dissections supplemented by micro-CT visualisation, a comparison of the crop of workers, soldiers and virgin queens and its capacity for considerable expansion was compared and food dyes revealed the storage of fat in the crop.

The roles of the queen, brood, and worker castes in the colony growth dynamics of the pharaoh ant Monomorium pharaonis (Hymenoptera: Formicidae)

The results showed that the number of caste components required for colony success was much lower than expected: A mere 50 workers and one queen were sufficient for colony survival and productivity irrespective of the presence of brood.

Pharaoh ant colonies dynamically regulate colony demography by culling young queen and male-destined larvae

The success of social insect colonies is dependent upon efficient and dynamic allocation of resources to alternate queen and worker castes. The developmental and molecular mechanisms regulating the

Egg-Laying “Intermorphs” in the Ant Crematogaster smithi neither Affect Sexual Production nor Male Parentage

It is concluded that intermorph-laid eggs typically do not survive and that the storage of nutrients and their redistribution as eggs by intermorphs is effectively altruistic.

Pharaoh ant colonies dynamically regulate reproductive allocation based on colony demography

This study systematically manipulate colony demography to elucidate the social regulatory mechanisms of caste allocation in the ant Monomorium pharaonis and develops a conceptual model depicting how colonies integrate numerous individual-level caste determination decisions to regulate colony- level caste allocation.

Extraordinary starvation resistance in Temnothorax rugatulus (Hymenoptera, Formicidae) colonies: Demography and adaptive behavior

This study is the first to comprehensively study mechanisms of starvation resistance in ant colonies, linking demography and behavior, and found brood to be the only significant predictor of colony starvation resistance, but not the degree of polygyny.



Food Distribution and Storage in Colonies of Monomorium pharaonis (L.) (Hymenoptera: Formicidae)

Peanut oil, like the 1 M sucrose solution, was rapidly distributed among and stored internally by adult workers, and was distributed rapidly to all larval stadia.

Stimulation of fire ant queen fecundity by a highly specific brood stage.

Fourth instars of the fire ant stimulate ovarian development and egg-laying in the queen and suggest that a specialized group of workers transfers a fecundity-stimulating anal factor from early postmeconial brood to the queen.

Die Pharaoameise, Monomorium pharaonis (L.) (Hym., Myrmicidae)

This complex especially concerns laboratory experiences with artificial breeding and the effect of insecticides and pheromones as well as the strategy of control with sodium arsenate baits (as a model of control strategy based on the bait principle).
