The nematode phylum Nematomorpha contains organisms which are also known as horsehair worms or Gordian worms. We report here a male specimen of worm from horse farm in Balıkesir province, Turkey. body the was brown color and length about 38 cm. After fixed ethyl alcohol (80%) scanning electron microscopic (SEM) observations were carried out. Based on macroscopic SEM findings identified Gordius ...

A new nematode species in the order Mononchida, Miconchus prokini sp. nov., found Lake El'gygytgyn (Chukotka, Russia) is described and illustrated. The largest member of genus known to date. It morphologically close rex big body size, vulva position females, number precloacal supplements males relative length pharynx both sexes, but it has a longer (L = 7.7–13.1 mm M. vs. L 6.5–7.0 rex) spicule...

Sirex nigricornis F. (Hymenoptera: Siricidae) is a native woodwasp in eastern North America that inhabits dead and dying pine trees during its univoltine development. Sirex noctilio is native to Eurasia and North Africa and was discovered in the northeastern United States in 2004 after a century of accidental introductions across the Southern Hemisphere. Since then, it has spread to seven state...

The Atlantic anchoveta, Cetengraulis edentulus (Cuvier, 1829) is one of the most commercially important fish species in littoral Brazil. present study evaluates parasitic fauna this engraulid from southeastern Brazilian coast. Between October 2019 and March 2020, a total 100 specimens C. Sepetiba Bay, Rio de Janeiro, Brazil (22°57’44”S; 43°52’28”W), were examined. Eighty-five parasitized by at ...

Age, growth and reproduction were investigated for Chondrostoma regium, collected monthly (November 2007- August 2008) from the Dimeh Spring region, Zayandeh Roud River, Iran. The maximum age of collected female and male fish were estimated based on scale increments as five and four years respectively. Von Bertalanffy growth equations were calculated as L_t=246[1-e^(-0.206(t-0.034))], W_t=163.2...

ABSTRACT High infection rates of wild olive (Olea europaea sp. sylvestris) feeder roots and soil infestation by a new root-knot nematode were found in sandy soil at Vejer de la Frontera (Cádiz), southern Spain. Morphometric traits and analyses of the nematode esterase electrophoretic pattern as well as of the internal transcribed spacer 1 (ITS1)-5.8S gene and D2-D3 fragment of the 28S gene of r...
