ABSTRACT
Essential oils that were extracted by steam distillation from Origanum onites L. from northwest Turkey were analyzed using an Agilent GC-MSD system. Carvacrol was the major component (64.3%) of the oil. Both pure commercial carvacrol and essential oil at concentrations of 1.5%, 3.2%, 6.25%, 12.5%, 25%, 50%, and 100% (v/v) were tested for their effects against engorging Rhipicephalus turanicus, which were collected from cattle breeding in the region. Pure carvacrol killed all the ticks following 6 h of exposure, while 25% and higher concentrations of the oil were completely effective in killing the ticks by the 24th-hour post-treatment (p < 0.05). The concentrations of 6.25% and 12.5% killed all the ticks by day 2. Lethal concentrations for 50% (LC(50)) and 90% (LC(90)) of 2.34% and 7.12%, respectively, were detected 24 h post-treatment. These findings indicate that the essential oil of O. onites L. has potential to be utilized at reasonable concentrations to control tick infestations.

Myiasis is a disease caused by fly larvae. Although adult cases have been reported, neonatal myiasis is a rare condition and there are few reports about this subject. In this article, we report a 12-day-old female neonate who was referred to us due to larvae in her eyes and ears. She was infected with Lucilia spp. larvae and was treated with proper antibiotics.

Sixty four samples of house dust were examined in order to detect the prevalence of the mite species and to identity them in houses in Bursa. Thirty two houses with or without central heating system were included in the study. A total of 22 (34.38%) houses were found to be infested with house dust mites. The rate of infestation was 18.75% and 50.00% in the houses with and without central heating system, respectively. The mite species and their prevalence were as follows: 58.34% Dermatophagoides pteronyssinus, 16.67%, Glycophagus domesticus 12.50% Dermatophagoides spp., 4.16% D. farinae, 4.16% Tyrophagus spp. and 4.16% unidentified Acarid species.
