The monotypic genus Curiades Pascoe 1880 (Curculionidae: Entiminae: Naupactini) is redescribed based on the type species C. boisduvali (Boheman 1840), endemic to Río de Janeiro, Brazil. Curiades boisduvali shows a characteristic color pattern and vestiture composed of long erect setae that resembles species of Dasymutilla Ashmead 1899, a genus of Mutillidae (Hymenoptera) whose wingless females ...

Time has placed a halo of honour round this little book first published in 1881. It gives to-day, as it gave then, all that can be done in a case of poisoning. The use of stomach tube has been encouraged even in the case of con-osive poisons. If the gullet and the stomach have perished before the arrival of the medical man the patient is going to die in any case. Doubt has been cast on the effi...

The deadly box jellyfish (Sea Wasp, Habu-kurage in Japanese) Chiropsalmus quadrigatus Haeckel (Cubozoa) is distributed widely in the tropical Pacific region. In Japan, three fatal cases due to stings from this species have been reported officially. We successfully isolated C. quadrigatus toxin-A (CqTX-A, 44 kDa), a major proteinaceous toxin, for the first time, from the nematocysts of C. quadri...

The jewel wasp stings cockroaches and injects venom into their cerebral ganglia, namely the subesophageal ganglion (SOG) and supraesophageal ganglion (SupOG). The venom induces a long-term hypokinetic state, during which the stung cockroach shows little or no spontaneous walking. It was shown that venom injection to the SOG reduces neuronal activity, thereby suggesting a similar effect of venom...

b a ckground : scorpion sting is a major health problem in iran. the aim of current study was to measure the inci- dence rates of scorpion stings, mortality, recovery, and affected age groups. the results of treatment with and with out anti venom also were considered in the entire country during 2009 . m e t hods: all the data were collected from emergency section of different hospitals and the...

BACKGROUND Insect sting reactions are frequently reported, but population studies documenting the frequency and the relation to IgE-sensitization and serum tryptase are scarce. METHODS Questionnaire data and results from measurements of specific IgE against venom, major allergens and cross-reacting carbohydrate determinants (CCDs) were collected from 2,090 adult participants in a cross-sectio...

The present review article explains the salient features of hornet venom toxins, their physiological, biological and pharmacological effect on animals man. Hornets sting very fast inflict venom, which is more dangerous than those bees. Hornet contains both proteinaceous non-proteinaceous peptides i.e. scapin, adolapin, mellitin, mastoparans enzymes, mainly phospholipase hyaluronidase, show mult...

The parasitoid wasp Ampulex compressa induces a set of unique behavioral effects upon stinging its prey, the cockroach. It stings into the first thoracic segment inducing 2 to 3 min of transient flaccid paralysis of the front legs. This facilitates a second sting in the cockroach's head that induces 30 min of excessive grooming followed by a 2 to 5-week long lethargic state. In the present stud...

Over the span of two or three days in August, 1972, in two separate communities in eastern Massachusetts two men, one aged 39, the other 66, each without previous overt heart disease, were stung by wasps. Each went into shock rapidly after an interval of over a half-hour developed chest pain and, later, sequential electrocardiographic changes diagnostic of acute myocardial infarction. Each surv...
