Termites exhibit the most varied mechanisms of reproduction found within the social insects. The sexual reproduction is generally headed by the primary reproductives, derived from alates, which start a colony after swarming. The colony reproduction may be extended with the appearance of secondary reproductives, which are neotenic individuals generally derived from workers (ergatoids) or n…
A termite colony is composed of diverse castes with different behavior and morphology. Coptotermes gestroi and Cryptotermes brevis are the principal pest termites responsible for economical damage in urban areas of Brazil. Queens of C. gestroi present a physogastry or abdominal hypertrophy whereas queens of C. brevis do not develop it or the physogastry is incipient, once only occur an un…
Recent studies have shown a new panorama for the reproduction in termites, although many gaps still exist, mainly related to the species of the family Termitidae found at the Neotropical region. The appearance of neotenic reproductives in some species is already well established, but the contribution of ergatoid neotenics, which are derived from workers or pseudergates, to the dynamic of …
The manipulation of termite colonies by removing the primary reproductives may promote the appearance of neotenic reproductives, which are individuals originated from workers (ergatoids) or from nymphs (nymphoids) that develop their reproductive apparatus before they reach the adult phase. The impacts of neotenic reproductives on the termite colony structure, such as the differentiation o…

A termite colony may exhibit neotenic reproductives, which are young individuals that reached the maturation of their reproductive apparatus prior to the molt to imago. These reproductives are commonly of two types, namely nymphoid neotenics when derived from nymphs and ergatoid neotenics when derived from workers. Some termite species exhibit a biased production of one or another type of…
Asexual reproduction by parthenogenesis has been reported in some species of Isoptera, but recent studies focus on species of the genus Reticulitermes (family Rhinotermitidae) and there are few publications for other species of "lower termites". The genus Velocitermes belongs to the family Termitidae, which includes the "higher termites". Species of the genus Velocitermes are found in the…
