(Silvestri, 1901)

Constrictotermes cyphergaster [1] is a Neotropical species of open-air foraging nasute termite within the genus Constrictotermes . [2] This species is distributed widely throughout South America and lives within xeric habitats such as the savannas found in Paraguay, Bolivia, Central Brazil, and Northern Argentina. [3] [4] C. cyphergaster primarily builds arboreal and transient epigeic nests and mainly consumes dead woods at varying stages of decomposition. [5]

Description

Biology

Nests of C. cyphergaster are mostly arboreal and are typically found between 0.4 and 3 meters high on a host tree. [5] The nests vary between a reddish brown and grayish brown in color, are oval and the texture of the surface is reticulated. [6] Growth and proliferation of nests coincides with seasonal changes. Most of the new small nests that emerge during the wet season are satellite colonies, which is associated with increased seasonal polycalism within C. cyphergaster. In the Caatinga region of Brazil, common host trees include Croton blanchetianus, where most new small nests are found on, and Caesalpinia pyramidalis, which have a higher percentage of large nests. Some nests are more epigeic - i.e. present on the ground. Epigeic nests are associated with ephemeral residence and are believed to be satellite constructions of nearby colonies serving as refuge for workers moving in-between nests and possibly for storing food. The largest recorded population for a nest of C. cyphergaster was around 118,000 individuals, with a soldier:worker ratio of 1:2.8 respectively. [7] [5]

Constrictotermes cyphergaster is primarily active during the night and early morning where it forms extensive foraging columns out in the open via one or two openings from the nest. Soldiers spearhead column formation 30 minutes before the arrival of workers within the foraging exodus. Leading soldiers branch off different routes from the main foraging column, while soldiers upstream assume defensive positions at the flanks of the foraging column to protect inbound workers. Once a feeding spot is located (typically a rotted tree trunk or branch), workers will gather around and consume material before returning with their new forage stored in their gut (unlike their Indomalayan counterparts which carry back food in their mandibles). On average, colonies forage over an area of 369.6±242.7 m2 during the dry season and 190.8±170.1 m2 during the wet season. The number of individuals involved in foraging varies by season with the largest number of workers involved in a single session, an estimated 87,000 individuals, being observed during a foraging bout in the wet season while during the dry season the largest recorded was 51,000 individuals. A maximum trail length of 18.5 meters was also observed for C. cyphergaster, which is smaller than the values recorded for other species of open-foraging termite. [5]

Foraging bouts are most frequent during the wet season and less so in the dry season, coinciding with seasonal variation in the availability of resources and foraging cycles. Somewhat contradictory, the biomass of colonies were observed to increase during the dry season, likely due to increased production of reproductive individuals (alates). Presumably the termites in preparation for adverse conditions forage more frequently in the wet season when resources are plentiful and when conditions are more favorable for foraging. Collected food is then stored within cells of the inner basal portion of the nest. These cells contain a dark material — digested balls of cellulose, which contain a high diversity of lignocellulosic ascomycetes fungi which help nutritionally enrich the food stores. The larvae of C. cyphergaster presumably feeds on these food stores, as well as Inquiline species of termite. [8] [5]

Reproduction

Colonies swarm in the following months: March, April, and May. The fully claustral royal pair likely found colonies within the ground which migrate to form arboreal nests later during the colony's lifecycle.

Termites are a group of detritophagous eusocial insects which consume a wide variety of decaying plant material, generally in the form of wood, leaf litter, and soil humus. They are distinguished by their moniliform antennae and the soft-bodied and often unpigmented worker caste for which they have been commonly termed "white ants"; however, they are not ants, to which they are distantly related. About 2,972 extant species are currently described, 2,105 of which are members of the family Termitidae.

Blattodea is an order of insects that contains cockroaches and termites. Formerly, termites were considered a separate order, Isoptera, but genetic and molecular evidence suggests they evolved from within the cockroach lineage, cladistically making them cockroaches as well. The Blattodea and the mantis are now all considered part of the superorder Dictyoptera. Blattodea includes approximately 4,400 species of cockroach in almost 500 genera, and about 3,000 species of termite in around 300 genera.

<span class="mw-page-title-main">Inquiline</span> Animal that lives commensally in the dwelling place of another species

In zoology, an inquiline is an animal that lives commensally in the nest, burrow, or dwelling place of an animal of another species. For example, some organisms, such as insects, may live in the homes of gophers or the garages of humans and feed on debris, fungi, roots, etc. The most widely distributed types of inquiline are those found in association with the nests of social insects, especially ants and termites – a single colony may support dozens of different inquiline species. The distinctions between parasites, social parasites, and inquilines are subtle, and many species may fulfill the criteria for more than one of these, as inquilines do exhibit many of the same characteristics as parasites. However, parasites are specifically not inquilines, because by definition they have a deleterious effect on the host species, while inquilines have not been confirmed to do so.

<span class="mw-page-title-main">Blond capuchin</span> Species of New World monkey

The blond capuchin is a species of capuchin monkey endemic to northeastern Brazil. This endangered species was rediscovered in 2006. It can live in exceptionally large groups of over 150 individuals, and like other capuchin species, exhibits a complex and high level of sociality. It is threatened by loss of habitat due to agriculture, primarily sugarcane fields. In many cases this has caused sugarcane to make up a large portion of their diet, which would otherwise consist of mostly fruit and small animals. The blond capuchin is known to inhabit both the Atlantic forest and Caatinga biomes, although the habitation of the Caatinga may be a recent choice caused by human encroachment into its former habitats. Like other primate species, the blond capuchin is also threatened by poaching and capture for the illegal pet trade.

Constrictotermes is a genus of Neotropical higher termites within the subfamily Nasutitermitinae. They form large open-air foraging columns from which they travel to and from their sources of food, similar to the Indomalayan species of processionary termites. Species of this genus commonly build epigeal or arboreal nests and feed on a variety of lichens, rotted woods and mosses.

Rhynchotermes is a genus of Neotropical higher termites within the subfamily Syntermitinae, represented by 8 known species. Species of this genus are known for their soldiers which have highly developed sickle-shaped mandibles and a pronounced frontal tube superficially analogous to the fontanellar guns of true nasute termites. Most species forage above the surface in the open where they primarily feed on forest leaf litter. Nests are subterranean or are shallow and epigeic.
