Photoreactions of Partially Blinded Whip-tail Scorpions
The experiments dealt with in this paper were devised to ascertain (1) the relative effectiveness as photoreceptors of the whip-tail scorpion's median eyes, lateral eye groups, and cutaneous sensitive areas, and (2) the effect on orientation produced by symmetrical and by asymmetrical interference with the photoreceptive mechanism. Each of the receptors was eliminated unilaterally and bilateral...
متن کاملNew products of defense secretion in south east Asian whip scorpions (Arachnida: Uropygi: Thelyphonida).
Secretion products from the opisthosomal defense gland of south east Asian whip scorpions were identified for the first time by gas-chromatography and mass-spectrometry. Specimens of the genera Hypoctonus, Typopeltis and Ginosigma were tested. While some ingredients are present in large concentrations, others are possibly only side products and may be synthesized more incidentally. For this rea...

متن کاملPhotoreactions of Nitrodiphenyl Ethers
Photoinduced nucleophilic substitution reactions of thirty p-nitrodiphenyl ethers including the herbicides nitrofen and chlornitrofen with a variety of amines were examined. The reaction took place by liberating nitrophenoxide or nitrite, depending on the substituents. Nitrofen liberated mainly nitrophenoxide by reactions with pyridine and 4methylpyridine to give N-phenylpyridinums, whereas chl...
متن کاملScorpion Sheds ‘Tail’ to Escape: Consequences and Implications of Autotomy in Scorpions (Buthidae: Ananteris)
Autotomy, the voluntary shedding or detachment of a body part at a determined cleavage plane, is a common anti-predation defense mechanism in several animal taxa, including arthropods. Among arachnids, autotomy has been observed in harvestmen, mites, and spiders, always involving the loss of legs. Autotomy of the opisthosoma (abdomen) was recently reported in a single species of the Neotropical...
