background: the distribution and ecological preferences of ticks of domestic animals in north of iran were studied four times a year from 2002 to 2005. methods: a total of 1720 tick specimens were collected from cattle, sheep and goats from different localities of caspian sea areas consisting of guilan, mazandaran, golestan and ardebil provinces, iran. results: fourteen tick species were identi...

Rhynocoris marginatus Fabricius (Hemiptera: Reduviidae) is an important biological control agent against more than 25 insect pests in India. For a better understanding of the feeding adaptation of this bug, the gross morphology and histology of its head and salivary apparatus were studied using both a light microscope and scanning electron microscope. The head is more or less elongate, mobile, ...

The neuropeptide Fs (NPFs) are an invertebrate subgroup of the FMRFamide-like peptides, and are proposed by some to be the homologs of vertebrate neuropeptide Y. Although there is some information about the identity, tissue distribution and function of NPFs in insects, essentially nothing is known about them in crustaceans. We have identified and characterized NPF-encoding transcripts from the ...

We provide data on morphological characteristics and the distribution of nemipterid fish Nemipterus marginatus (Valenciennes, 1830) in estuary coastal area Thanh Hoa province, North Central Vietnam. This is also a clear location record for this species region compared to previous studies, new study area.

Dusky grouper (garoupa, Epinephelus marginatus) is an important catch for several artisanal small-scale fisheries along the Brazilian coast. It is a sedentary, monandric, and late maturing protogynous species, which makes it vulnerable to overharvesting even though it is mainly caught through hook and line or spear fishing through free diving. Lack of information on the ecology and biology of t...

BACKGROUND: Ticks are the most important vectors whichtransmit several arthropod-borne diseases such as theileriosis,babesiosis, and anaplasmosis. OBJECTIVES: An epidemiologicalstudy was conducted in Semnan area to determine thecurrent situation of tick infestation in sheep and assess theefficacy of usage of CIS-cypermethrin against tick infestationunder field condition. METHODES: Sampling was ...

Pseudothilmanus Pic, 1918 is redescribed and two species, P. alatus Pic, 1918 and P. marginatus Pic, 1918, are placed in the genus. The subgenus Drilothilmanus Pic, 1918 is synonymized with the nominotypical genus on the basis of low morphological divergence and redundancy in classification. Pseudothilmanus is newly classified in the family Rhagophthalmidae, in contrast to the original placemen...
