Chemical defense of an earwig (Doru taeniatum)

  title={Chemical defense of an earwig (Doru taeniatum)},
  author={Thomas Eisner and Carmen Rossini and Maria Eisner},
Summary. The earwig Doru taeniatum (Dermaptera, Forficulidae) has a pair of defensive glands, opening on the 4th abdominal tergite, from which it discharges a spray when disturbed. It aims the discharges by revolving the abdomen, a maneuver that enables it simultaneously to use its pincers in defense. The secretion contains two quinones (methyl-1,4-benzoquinone and 2,3-dimethyl-1,4-benzoquinone) present in the glands as a crystalline mass, together with pentadecane and a (presumably) aqueous…

Benzoquinones from scent glands of phalangiid harvestmen (Arachnida, Opiliones, Eupnoi): a lesson from Rilaena triangularis
The pungent-smelling secretion was analyzed by gas chromatography–mass spectrometry and found to contain mainly 1, 4-benzoquinone along with 1,4-naphthoquinone and caprylic (=octanoic) acid.
Biosynthetic origin of benzoquinones in the explosive discharge of the bombardier beetle Brachinus elongatulus
The results refute the previous claim that 1,4-hydroquinone is the precursor of all substituted benzoquinones in bombardier beetles and reveal that they are biosynthetic products of two independent pathways.

The shore earwig when bitten by anole lizards, Anolis carolinenesus, spits a rotting-flesh odor that deceives these insectivores into rejecting prey, the first report of insects releasing sulfur-containing compounds that may mimic carrion-fecal odors as a deceptive defense against vertebrate predators.
Noxious Menu: Chemically Protected Insects in the Diet of Caracara cheriway (Northern Crested Caracara)
Analysis of regurgitated pellets of Caracara cheriway (Northern Crested Caracaras) at a site in south-central Florida produced a wide variety of insects and spiders from 34 families and at least 72 genera, indicating the list of noxious chemicals ingested by these raptors with their insect food may be even more extensive than is now evident.
Chemical composition of anther volatiles in Ranunculaceae: genera-specific profiles in Anemone, Aquilegia, Caltha, Pulsatilla, Ranunculus, and Trollius species.
It is shown that most species belonging to the same genus have similar chemical compositions, including aliphatic compounds, aromatics, mono- and sesquiterpenoids, and nitrogen-bearing compounds.
Multiple Lines of Egg Defense in a Neotropical Arachnid with Temporary Brood Desertion
It is proposed that the presence of multiple lines of egg defense may have evolved as a way of lowering the costs imposed by intra- and interspecific egg predation during periods of temporary brood desertion.
Maternal care provides antifungal protection to eggs in the European earwig
This study shows that maternal egg attendance in the European earwig has a social defense function protecting offspring against mold infection, probably through both the mechanical removal of spores and the continued application of chemical substances on the egg surface.


Defense of Phalangid: Liquid Repellent Administered by Leg Dabbing
The phalangid Vonones sayi has a pair of exocrine defensive glands that secrete quinones that effects dosaged delivery of the mixture by brushing it on the assailant with the tips of its forelegs.
Fine structure of insect epidermal glands
The present review is devoted to the exocrine glands derived from epidermis; glands associated with the preoral cavity (mandibular, salivary, etc) and genital apparatus are not dealt with except for
