Achaemenothrombium cyrusi gen. et sp. nov. (Acari, Prostigmata: Trombidioidea) is described and illustrated from larvae ectoparasitic on Catocala sp. (Lepidoptera: Noctuidae) from Tehran, Iran and Achaemenothrombium talebii (Karimi Irvanlou & Kamali, 2001) comb. nov. is redescribed. A new family, Achaemenothrombiidae is proposed for accommodating this genus. A key to families of larval Trombidi...

Introduction Varroa destructor Anderson & Trueman (2000) is an ectoparasitic mite which causes severe damage to Apis mellifera populations worldwide. Adult females of V. destructor feed directly on the haemolymph of honey bee pupae and can activate and transmit honeybee viruses. Infestation causes an increased prevalence of bee diseases and colony mortality, resulting in decline of honey produc...

Myiasis is due to the opportunistic dipterous larvae feeding on viable or necrotic tissues of the host occurring throughout the world. We report a case of oral myiasis in an immune-compromised patient suffering from non-Hodgkin lymphoma. We would like to emphasize that such ectoparasitic infections may happen in immunocompromised patients and oral hygiene should be evaluated in all of these pat...

In this paper, three separate instances of an association between an ectoparasite, Cyclocotyla bellones (Otto, 1821) (Monogenea: Diclidophoridae) and ectoparasitic isopods have been reported for the first time from the Aegean Sea coasts of Turkey. The isopods were all of the family Cymothoidae: Ceratothoa oestroides, C. parallela, Emetha audouini.

Sea lice infestations have become a major health problem for farmed salmonids throughout the world including Chile. In southern Chile, 6 geographical areas, divided into 22 geographical zones with a total of 127 salmon farming centers and 1519 sea pens, were regularly sampled from December 1999 to April 2002. A linear mixed-effects model (LME) approach was used to describe the infestations of a...

The recombinant Bm86-based tick vaccines have shown their efficacy for the control of cattle ticks, Rhipicephalus (Boophilus) microplus and R. annulatus infestations. However, cattle ticks often co-exist with multi-host ticks such as Hyalomma and Amblyomma species, thus requiring the control of multiple tick infestations for cattle and other hosts. Vaccination trials using a R. microplus recomb...

Community participation is the main strategy to sustainability of Chagas disease entomological surveillance. The purpose of this study was to evaluate the level of knowledge on triatomine insects and Chagas disease among the residents from eight localities of Diamantina, in Minas Gerais, with a view to observing any associations between their knowledge and infestations by triatomines. In order ...

BACKGROUND Lynxacarus radovskyi (fur mites) are ectoparasites found on the hair shafts of cats living in tropical environments. Diagnosis is via microscopic examination of hairs. Various anatomical areas have been reported to harbour these mites. OBJECTIVES To assess adhesive tape impressions and trichograms for detecting L. radovskyi and co-infestations; to determine host body predilection s...

The present study aimed to evaluate the occurrence of immune resistance in dogs successively infested with Amblyomma cajennense nymphs. Five animals were submitted to four consecutive infestations with A. cajennense nymphs, at fourteen-day intervals. For each infestation, 50 nymphs were used per animal and data on the parasitic and non-parasitic periods were recorded. The average recovering rat...
