As Neocapritermes taracua termites age, they develop a suicidal toxic apparatus that bursts during aggressive encounters. By nature, defensive behavior is risky. In social insects, such behavior is more likely to occur in individuals whose potential for other tasks is diminished. We show that workers of the termite Neocapritermes taracua develop an exceptional two-component suicidal apparatus consisting of copper-containing protein crystals, stored in external pouches, and internal salivary… 

Molecular Mechanism of the Two-Component Suicidal Weapon of Neocapritermes taracua Old Workers.

This work identifies both components of this activated defense system and describes the molecular basis responsible for the toxicity of N. taracua worker autothysis, a sticky and toxic cocktail harmful to opponents.

Involvement of the Salivary Glands in the Suicidal Defensive Behavior of Workers in Neocapritermes opacus (Blattaria, Isoptera, Termitidae)

The suicidal mechanism in workers of the Neotropical termite Neocapritermes opacus, which involves salivary gland autothysis followed by body cuticle rupture and the release of a defensive secretion, was investigated.

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.

Comparative Study of the Labial Gland Secretion in Termites (Isoptera)

The results highlight the dual role of labial gland secretion, i.e. the defensive role in soldiers and workers of several termite species, and the digestive function in workers.

The labral gland in termite soldiers

This study is the first to provide a comprehensive picture of the structure of the labral gland in soldiers across all Termite taxa, and suggests that thelabral gland is involved in communication rather than defence as previously suggested.

Termite Valkyries: Soldier-Like Alate Termites From the Cretaceous and Task Specialization in the Early Evolution of Isoptera

Valkyries are the first termite reproductives known with defensive features and suggest that phragmosis arose at least in the Early Cretaceous, and support the hypothesis that the division between reproductive and defensive tasks has not always been complete in termite history.



Structure and function of defensive glands in soldiers of Glossotermes oculatus (Isoptera: Serritermitidae)

The structure and function of defensive glands in Glossotermes oculatus soldiers aiming to understand their use in combat are investigated and it is hypothesized that this self-sacrifice is an efficient way of blocking a gallery under attack.

Chemical warfare in termites.

A review on self-destructive defense behaviors in social insects

An overview of the self-destructive defense mechanisms that eusocial insects have evolved is provided and avenues for future research into this form of altruism are discussed.

Regulation of division of labor in insect societies.

A key feature of the division of labor in insect colonies is its plasticity, which enables it to continue to grow, develop, and ultimately produce a new generation of reproductive males and females despite changing colony conditions.

Feeding ecology and phylogenetic structure of a complex neotropical termite assemblage, revealed by nitrogen stable isotope ratios

1. In the current ecological classification of termites, four feeding groups (I–IV) are recognised, corresponding to a gradient of decomposition from sound wood to highly mineralised organic matter

Cleavage of Structural Proteins during the Assembly of the Head of Bacteriophage T4

Using an improved method of gel electrophoresis, many hitherto unknown proteins have been found in bacteriophage T4 and some of these have been identified with specific gene products. Four major

Off-line coupling of capillary electrophoresis to substrate-assisted laser desorption inductively coupled plasma mass spectrometry.

A novel off-line coupling of capillary electrophoresis (CE) and inductively coupled plasma mass spectrometry (ICPMS), based on the connection of a separation capillary to a deposition capillary via a liquid junction maintaining high separation efficiency and sample utilization is reported here.

The analysis of ranked data derived from completely randomized factorial designs.

The procedure, which is an extension of the Kruskal-Wallis ranks test, allows for the calculation of interaction effects and linear contrasts in ranked data arising from completely randomized factorial designs.
