Cryptotermes Cynocephalus
The Indo-Malaysian drywood termite, (''Cryptotermes cynocephalus''), is a species of dry wood termite of the genus ''Cryptotermes''. It is found in Philippines, Australia, Papua New Guinea, Hawaii, and introduced to Sri Lanka. It is the smallest termite species in Australia, with 2.5 – 3.7mm in soldiers. Description *Imago - General body color is pale brown. Abdomen is darker than head and pronotum. Jointed appendages are creamy white. *Soldier - On soldier's head, there is a strongly V-shaped frontal flange. Head is complete black with orange posterior. Head strongly concave in middle. Mandibles short and stout. Teeth are weak. Eyes very small and rudiment-like. Impact The feeding preference of this species of drywood termites was found to be from most to least preferred: ''Falcataria moluccana'', ''Acacia mangium'', ''Gmelina arborea'', ''Swietenia macrophylla'', and ''Eucalyptus deglupta'' in a series of no-choice and choice feeding trials in the Philippines.

Termites
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 an ...

On the opposite spectrum, Fijians use its (''vasa'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oleic Acid
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 ''cis''-9, and a main product of Δ9 desaturase. It has the formula CH3(CH2)7CH=CH(CH2)7COOH. The name derives from the Latin word ''oleum'', which means oil. It is the most common fatty acid in nature. The salts and esters of oleic acid are called oleates. Occurrence Fatty acids (or their salts) often do not occur as such in biological systems. Instead fatty acids such as oleic acid occur as their esters, commonly triglycerides, which are the greasy materials in many natural oils. Oleic acid is the most common monounsaturated fatty acid in nature. It is found in fats (triglycerides), the phospholipids that make membranes, cholesterol esters, and wax esters. Triglycerides of oleic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system.
