Pharaoh ant

A list of the pharaohs is contained on a papyrus scroll called The Blood of the Pharaohs. One copy is kept in the library of Brooklyn House , which includes the name Kane written in hieroglyphs. Those with the blood of the pharaohs are currently being persecuted by the House of Life for following the Path of the Gods.

Sadie and Carter have begun to use Osiris 's djed to call others like them to Brooklyn House. Anyone who has the blood of the pharaohs has the right to become the Pharaoh of the House of Life. Carter Kane eventually took up this position after Apophis was destroyed. According to Thoth , those who have the blood of the pharaohs always have the ability to summon boats to take them to the Duat if needed. The Kane family has the ability to summon the Egyptian Queen and can also use Ra 's sunboat.

Many invasive ants display unicoloniality. The adaptive value of this nonaggression among colonies has to do with avoiding unnecessary injury and allowing proper resource allocation , ensuring success for all the colonies. Low nestmate recognition, caused in part by polygyny, also has a biochemical basis in M. Cuticular hydrocarbons are compounds, often found on antennae , that allow for communication in many social insects. In ant species, these compounds play an especially key role in nestmate recognition. Differences in cuticular hydrocarbons are detected by other ant species, who respond accordingly.

However, all pharaoh ant colonies have the same hydrocarbons on their antennae. This leads to ineffective nestmate recognition, and nonaggression between colonies. Pharaoh ant colonies contain many queens. The ratio of queens to workers is variable and dependent on the size of the colony. An individual colony normally contains 1,—2, workers, but often a high density of nests gives the impression of massive colonies. In a small colony, there will be more queens relative to workers.

In addition, individuals will be larger than those in a more populous colony. Larvae that will produce workers have characteristic hairs all over them, while larvae that will produce sexual males or females are bare. It is thought that workers can use these distinguishing features to identify larvae.

Workers may cannibalize larvae in order to ensure a favorable caste ratio. This decision to cannibalize is largely determined by the present caste ratio. If plenty of fertile queens are present, for example, the workers may eat sexual larvae. The caste ratios are controlled in an attempt to maximize the growth of the colony.

This in turn increases the potential for reproduction, allowing colony growth. Conversely, in a large colony, the high worker to queen ratio maximizes the foraging capacity of the nest, helping sustain the population size.

The Pharaoh ant is a polygynous species that has a relatively low worker to queen ratio of around This allows the pharaoh ants to be able to exert social control over the size of the colony and the size of each caste. This low worker to queen ratio is usually associated with swift changes in the nest and may be why pharaoh ants form many new nest buds quickly. Mating for pharaoh ants occurs within the nests with males that are usually not from the colony which ensures genetic diversity.

The queen can typically produce eggs in batches of 10 to 12 at once, but can lay up to eggs every time she mates. The eggs that are produced take up to 42 days to mature from an egg to an adult. Each queen within the nest lives between 4 and 12 months. During copulation , sperm is transferred from male to female inside a spermatophore.

There are several theories regarding the adaptive value of using a spermatophore.

In either explanation, the spermatophore prevents the female from reproducing with another male. Pharaoh ant copulation, like that of many social insects, is harmful to the female. The penis valve contains sharp teeth, which latch onto a thick, soft cuticular layer in the female. This method of copulation too has an evolutionary basis. The teeth ensure sex lasts long enough for sufficient sperm transfer.

Also, the pain caused to the female may, in some ways, lessen her desire to mate again. When the queen ant first moves to a new nest, she will rear the first group of workers.

Once a worker threshold has been reached, resources will then be invested into new males and queens. When a new nest is formed, queens are not a necessity; workers can raise new queens after finding a suitable nest site. In pharaoh ant colonies new males and queen ants can be produced when the existing fertile queen is removed. When queens are absent, the workers in the nest can do two things: However, when there are fertile queens still within the nest, the worker ants will cannibalize the sexual larvae and will either reject or consume sexual larvae from other nests.

On the other hand, the worker ants will always accept and nurture worker larvae from other nests.

When social ants encounter ants from another colony, behavior can be either aggressive or non-aggressive. Aggressive behavior is very commonly seen; the attacking worker usually bites the opponent at the petiole. In non-aggressive behavior, antennation occurs when the two ants meet.

In the case of Monomorium pharaonis , behavior is almost always non-aggressive even when the ants are from different colonies and of different castes. After foraging, pharaoh ants will wash themselves when a worker enters the cell. Pharaoh ants will also wash after a long feed. It has been proposed that washing has a hygienic value, keeping the nest area clean, staving off disease and disorder. Right before workers leave to forage, they also may wash themselves. However, in this instance the behavior is extremely violent, often causing the ants to fall over. It is thought that here, the washing behavior has no hygienic value and instead may be a displacement activity , a sign that the ants are deliberating whether or not to exit the nest.

Budding is a major factor underlying the invasiveness of pharaoh ants. A single seed colony can populate a large office block, almost to the exclusion of all other insect pests, in less than six months. Elimination and control are difficult because multiple colonies can consolidate into smaller colonies during extermination programs only to repopulate later. Pharaoh ants have become a serious pest in almost every type of building.

They can feed on a wide variety of foods including grease, sugary foods, and dead insects. They can also gnaw holes in silk , rayon and rubber goods. Nests can be very small, making detection even more difficult. It is recommended not to attempt extermination using insecticidal sprays and dusts because they will cause the pharaoh ants to scatter and colonies to split, although non-repellent residual insecticides have been reported to be effective.

The recommended method to eliminate pharaoh ants is by the use of baits attractive to the species. Modern baits use insect growth regulators IGRs as the active substance; the ants are attracted to the bait by its food content, and take it back to the nest. Over a period of weeks the IGR prevents the production of worker ants and sterilizes the queen.
