Medically important beetles (insecta: coleoptera) of Iran
Provedor de dados: 80
Autores: Nikbakhtzadeh,MR; Tirgari,S.
This study focused on coleopteran species that are responsible for the emergence of recent cases of dermatological manifestations in Iran. To the best of our knowledge, five species of the family Meloidae and nine species of the genus Paederus are by far the only beetles recognized as medically important in Iran. The staphylinids consists of Paederus ilsae, P. iliensis, P. fuscipes, P. kalalovae, P. balcanicus, P. lenkoranus, P. littoralis, P. carpathicus, P. nigricornis, while the meloids are Mylabris impressa, M. guerini, Muzimes iranicus, Alosimus smyrnensis and Epicauta sharpi. Most cases of linear dermatitis in this country occur in areas bordering the Caspian Sea. This problem is caused by beetles of the genus Paederus which are present as adults...

Bioecology and chemical diversity of abdominal glands in the iranian samsum ant Pachycondyla sennaarensis (Formicidae: Ponerinae)
Provedor de dados: 80
Autores: Nikbakhtzadeh,MR; Akbarzadeh,K; Tirgari,S.
The genus Pachycondyla is a large group of ants in the Ponerini tribe, known mostly from tropical and subtropical regions. Pachycondyla sennaarensis, the so-called Samsum ant in the Middle East, is distributed throughout the African tropics, Arabian Peninsula and Iran, where it is responsible for many cases of insect-induced dermal lesions and systemic reactions in humans. Populations of P. sennaarensis were studied in two regions of Iran and some aspects of their biology, ecology and medical importance are herein presented. Colonies of P. sennaarensis contain less than 850 workers that live in complicated underground galleries approximately one meter deep. Because of the harsh weather conditions of southern Iran, they can survive only in human disturbed...

Origin, transfer and distribution of cantharidin-related compounds in the blister beetle Hycleus scabiosae
Provedor de dados: 80
Autores: Nikbakhtzadeh,MR; Vahedi,M; Vatandoost,H; Mehdinia,A.
Cantharidin provides chemical protection for the coleopteran families Meloidae and Oedemeridae. In the present study, it was observed that cantharidin concentration in Hycleus scabiosae was slightly decreased from mated females (mean = 0.011 mg/mg of dry weight) to males (mean = 0.010 mg/mg) and considerably diminished in relation to virgin females (mean = 0.005 mg/mg). Significant concentrations of palasonin (21.69 ng/mg among virgins and 17.49 ng/mg in mated females) and palasoninimide (14.62 ng/mg in virgins and 9.17 ng/mg in mated females) were found in H. scabiosae. Palasonin, palasoninimide and cantharidinimide content of eggs were measured as 5.61, 7.69 and 7.80 ng/mg respectively. Surprisingly, males showed no trace of cantharidin-related compounds...
