Globitermes Sulphureus
''Globitermes sulphureus'' (suicidal attack ants) is a species of termite that is very common in central and southern Vietnam and also present in other areas of South East Asia, including Cambodia, Thailand, and Peninsular Malaysia. They live in nests made of earth that can be up to 1.5 m tall and can contain tens of thousands of individuals. Between five and 10 per cent of the population are soldier termites which can be recognised by their yellow abdomen and two large, curved mandibles. The termites use autothysis as a defense mechanism. Defense When the nest is damaged, the soldier termites defend the nest and workers rapidly repair any damage to the nest walls. The soldiers stand on alert on their legs and scan the area with their antennae. If the nest is attacked by ants, for example ''Oecophylla smaragdina'', the workers immediately escape by retreating into the nest, while the soldiers remain outside to defend the nest. They will first attempt to catch and pierce the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autothysis
Autothysis (from the Greek roots ''autos-'' "self" and ''thysia'' "sacrifice") or suicidal altruism is the process where an animal destroys itself via an internal rupturing or explosion of an organ which ruptures the skin. The term was proposed by Ulrich Maschwitz and Eleonore Maschwitz in 1974 to describe the defensive mechanism of ''Colobopsis saundersi'', a species of ant. It is caused by a contraction of muscles around a large gland that leads to the breaking of the gland wall. Some termites (such as the soldiers of ''Globitermes sulphureus'') release a sticky secretion by rupturing a gland near the skin of their neck, producing a tar effect in defense against ants. Termites Groups of termite whose soldiers have been found to use autothysis to defend their colonies include: '' Serritermes serrifer'', '' Dentispicotermes'', '' Genuotermes'', and '' Orthognathotermes''. Several species of the soldierless Apicotermitinae, for example those of the '' Grigiotermes'' and '' Rupti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Termite Genera
Termites are small insects that live in colonies and have distinct castes (eusocial) and feed on wood or other dead plant matter. Termites comprise the infraorder Isoptera, or alternatively the epifamily Termitoidae, within the order Blattodea (along with cockroaches). Termites were once classified in a separate order from cockroaches, but recent phylogenetic studies indicate that they evolved from cockroaches, as they are deeply nested within the group, and the sister group to wood eating cockroaches of the genus '' Cryptocercus''. Previous estimates suggested the divergence took place during the Jurassic or Triassic. More recent estimates suggest that they have an origin during the Late Jurassic, with the first fossil records in the Early Cretaceous. About 3,106 species are currently described, with a few hundred more left to be described. Although these insects are often called "white ants", they are not ants, and are not closely related to ants. Like ants and some bees a ...

Amitermitinae
Amitermitinae is a disputed subfamily of "higher termites" now often merged with the subfamily Termitinae and is considered by ITIS as a synonym; it had previously been placed in the family Rhinotermitidae. Amitermitinae have as typical characteristics: a usually rounded head with a bilobed clypeus. The mandibles of their soldiers usually has a single median tooth. They have evolved the ability to have many reproductives in their colony, up to a hundred, which allows very large colonies. As with other members of their family, Termitidae, they have lost most of their cellulose-digesting protozoa. Instead, they eat fungi, which digest cellulose and other organic matter. As a result, the Termitidae can make use of a wide variety of foods; not only rotten wood, but also grass, seeds, dung, soil, and detritus are all used by one species or another. In addition, some species can synthesize nitrogen compounds. Many members of the Amitermitinae have evolved a very effective way of ...

Yunnan
Yunnan , () is a landlocked province in the southwest of the People's Republic of China. The province spans approximately and has a population of 48.3 million (as of 2018). The capital of the province is Kunming. The province borders the Chinese provinces of Guizhou, Sichuan, autonomous regions of Guangxi, and Tibet as well as Southeast Asian countries: Vietnam, Laos, and Myanmar.

Yunnan is situated in a mountainous area, with high elevations in the northwest and low elevations in the southeast. Most of the population lives in the eastern part of the province. In the west, the altitude can vary from the mountain peaks to river valleys by as much as . Yunnan is rich in natural resources and has the largest diversity of plant life in China. Of the approximately 30,000 species of higher plants in China, Yunnan has perhaps 17,000 or more. Yunnan's reserves of aluminium, lead, ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...
