Soldier defense secretions ofTrinervitermes bettonianus (Isoptera, Nasutitermitinae): Chemical variation in allopatric populations

  title={Soldier defense secretions ofTrinervitermes bettonianus (Isoptera, Nasutitermitinae): Chemical variation in allopatric populations},
  author={Glenn D. Prestwich and Doris C. Chen},
  journal={Journal of Chemical Ecology},
The soldier defense secretions of major and minor soldiers of the East African nasute termiteTrinervitermes bettonianus were analyzed chromatographically and spectrometrically, and the diterpene and monoterpene constituents were determined for three allopatric populations. Incipient colonies from one population raised on food from a second population produced their population-specific terpene pattern independent of food source. Secretion compositions are thus genetically rather than… 

Extreme intraspecific chemical variability in soldier defense secretions of allopatric and sympatric colonies ofLongipeditermes longipes

Three new natural products are included in this remarkable and unprecedented example of structural diversity among different colonies of a single species of primitive glue-squirting nasute termite.

Diterpene composition of defense secretion of four west AfricanTrinervitermes soldiers

The diterpene composition of the defensive secretions of minor and major soldiers is described for four sympatricTrinervitermes from the Ivory Coast to suggest that the differences between minor andMajor soldiers is as large within a nest as between different nests.

Isolation, identification, and biological activity of trail-following pheromone of termiteTrinervitermes bettonianus (Sjöstedt) (Termitidae:Nasutitermitinae)

The principal compound which posseses trail-following activity at low concentration has been isolated from workers and from female alates of the grass feeding termiteTrinervitermes bettonianus. Male

Sesquiterpenes in the frontal gland secretions of nasute soldier termites from New Guinea

In five New GuineaNasutitermes the sesquiterpenic fraction of soldier frontal gland secretion is equal to that of the monoterpenes.

Chemical warfare in termites.

Two New C‐20 Substituted Trinervitane Diterpenes from a Neo‐Guinean Nasutitermes SP(1)

Two new 1 (15), 8 (19)‐trinervitadiene derivatives have been isolated from the frontal secretion of an undescribed species of nasute termite (Nasutitermes sp PNG (F)). They have been identified as

Ecology of Termites

The ecological role of termites is examined and explored and it is shown that these tiny insects are a center of attraction because they damage the human economy as wood pests.

Evaluation of the chemical defense fluids of Macrotermes carbonarius and Globitermes sulphureus as possible household repellents and insecticides

The results demonstrate the potential use of termite defense fluid for pest management, providing repellency and insecticidal activities comparable to those of other green repellent and termiticidal commercial products.

Isolation, structure determination, synthesis, and biochemistry of the low-molecular-weight compounds of the secretion of exocrine glands of termites are described, with an emphasis on pheromones and



Isotrinervi-2β-ol. Structural isomers in the defense secretions of allopatric populations of the termiteTrinervitermes gratiosus

The defense secretions of 3 allopatric populations of the nasute termiteTrinervitermes gratiosus were analyzed. One population afforded a new trinervitene, isotrinervi-2β-ol, a missing link in the

Defensive behavior of a termite (Nasutitermes exitiosus)

It is suggested that in nature, sprayed incapacitated enemies might be covered over by the workers with feces and soil, a behavior that could bring about a more timely blockage of the alarm signal.

Chemical defense by termite soldiers

The chemistry of the defensive secretions of termite soldiers is reviewed. The structural variety of the chemical weapons, the uses of these substances in defense, and some potential biosynthetic

Behavior of the North American termite Tenuirostritermes tenuirostris, with special reference to the soldier frontal gland secretion, its chemical composition, and use in defense

Tenuirostritermes is a small genus of Neotropical termites with two species ranging northward into warm temperate, semi-arid areas of southwestern Texas or beyond into southeastern Arizona, as a member of the Nasutitermitinae.

Determination of the enantiomeric composition of several insect pheromone alcohols

Details are given for the determination of the enantiomeric composition of several insect pheromone alcohols. The two methods used in the determination were: formation of the derivative with
