Abstract Ontogenetic shifts in food preference reduces intraspecific competition as immature individuals eat different types than adults. This diet plasticity could facilitate species’ ability to successfully invade and establish itself a new environment, even when co-occurring with phylogenetically close species. Here, ontogenetic of non-native piranha species (Serrasalmus marginatus) was test...
Dalopius marginatus (L.) (Coleoptera: Elateridae) is a very common click beetle species developing in forest soils an area from southwest Europe to eastern Siberia. Here, we studied the composition of female-released sex pheromone D. using coupled gas chromatography-mass spectrometry (GC-MS). Neryl octanoate, neryl decanoate, and dodecanoate, ratio approximately 1:100:3, were only volatile comp...
Of 263 patients in Tuscany, Italy, from whom ticks were removed during July 2005-May 2007, five showed signs of tick-borne encephalopathy. Of the ticks, 17 were Dermacentor marginatus; 6 (35.3%) of these were identified by sequence analysis as containing Rickettsia slovaca. Tick-borne lympadenopathy occurs in this area.
This study reports the results of a comparative test of identification of ticks occurring in Western Europe and Northern Africa. A total of 14 laboratories were voluntarily enrolled in the test. Each participant received between 22 and 25 specimens of adult and nymphal ticks of 11 species: Dermacentor marginatus, D. reticulatus, Haemaphysalis punctata, Hyalomma lusitanicum, Hy. marginatum, Ixod...
Here we report on 16 microsatellite loci designed for the damselfish Dascyllus aruanus. All loci were tested on 98 individuals and were polymorphic (seven to 35 alleles). Expected heterozygosity ranged from 0.705 to 0.942. Six loci showed Hardy-Weinberg disequilibrium due to the occurrence of null alleles. Cross-species amplifications conducted within the genus Dascyllus (D. carneus, D. strasbu...
this study conducted during 3 years period (2002-2004). tick sampling was randomly carried out from domestic animals during seasonal activity of ticks from six provinces of iran. 2170 ticks from 151 cattle , 629 sheep, 336 goats and 32 camels were collected proin 30 prosseces with a mean number of 1.9 tick per animal. 209 dermacentor ticks collected from six provinces( kordestan, ardebil, east ...
The papaya mealybug (Paracoccus marginatus) Williams & Granara de Wilink (Hemiptera: Pseudococcidae) is a main pest of plants. Attacks by these pests can cause plants failed to produce the fruit and even death. usual control technique used farmers use synthetic pesticides that have negative impact on human health environment. alternative using botanical insecticides good solution population...
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 ...
