We evaluated the potential of Mesocyclops annulatus as a control agent of Aedes aegypti in La Plata city (Argentina). Mosquito larval survivorship due to predation by these copepods was estimated at weekly intervals during the oviposition period of A. aegypti. Mean weekly A. aegypti larval survivorship in cylindrical plastic containers (12 cm height and 11 cm diameter) with copepods was signifi...
A method for the identification of three ixodid tick species; the cow tick (Boophilus annulatus), the camel tick (Hyalomma dromedarii) and the cattle tick (Hyalomma anatolicum excavatum) based on restriction enzyme analysis of the second internal transcribed spacer (ITS-2) in the nuclear ribosomal DNA was adopted. PCR products with MW 1375 bp, 1650 bp and 1835 bp from B. annulatus, H. dromedari...
گلرنگ از جمله گیاهانی است که به لحاظ بومی بودن و سازگاری با شرایط اقلیمی کشور، از ویژگی های ارزشمندی برخوردار است. در حال حاضر هدف اصلی از زراعت گیاه گلرنگ استخراج روغن موجود در دانه آن است. مگس گلرنگ، acanthiophilus helianthi یکی از آفات مهم گلرنگ در سرتاسر جهان می باشد که هر ساله خسارات زیادی به این محصول وارد می کند. به منظور بررسی نوسانات فصلی مگس گلرنگ و شناسایی پارازیتوئیدهای آن در سال 13...
Ticks are obligate haematophagous ectoparasites of wild and domestic animals as well as humans, considered to be second worldwide to mosquitoes as vectors of human diseases, but the most important vectors of disease-causing pathogens in domestic and wild animals. Babesia spp. are tick-borne pathogens that cause a disease called babesiosis in a wide range of animals and in humans. In particular,...
The present study evaluates the acaricidal properties of crude ethanolic extract of Cassia fistula leaves for controlling Rhipicephalus (Boophilus) annulatus based on adult immersion test (AIT). The percentage of adult mortality, inhibition of fecundity and hatching of ova laid were studied at different concentrations of the extract ranging from 50 to 100 mg / ml. The results were compared usin...
A survey was carried out to investigate the prevalence of hard tick species (Acari: Ixodidae) on cattle in Mazandaran province, Iran. A total of 953 ticks were collected from 86 infested cattle during activating seasons of ticks during 2004-2005. Nine species were identified: Boophilus annulatus (51.3%), Rhipicephalus bursa (16.8%), Haemaphysalis punctata (6.3%), Ixodes ricinus (6.8%), Hyalomma...
We observed the mating behavior of the neck-banded snake Scaphiodontophis annulatus (a common species of colubrid in the South Pacific of Costa Rica) in the pre-montane wet forest of Las Cruces Biological Station (San Vito de Java, Costa Rica). Three S. annulatus were observed during courtship between 10-12 AM in a patch of primary forest. The two males were observed to interact with the female...
When Hereford heifers infested with Boophilus annulatus (Say) were treated with a single Ivomec SR Bolus, the concentration of ivermectin in the serum of the treated cattle reached a maximum of 8.8 +/- 0.9 ppb at 2 wk posttreatment. The single bolus treatment resulted in 84.4% control of standard engorging B. annulatus females on treated cattle over the 20-wk trial. Although fewer engorged tick...
