We are delighted to announce the upcoming congress commemorating the 100th anniversary of the first description of the entomopathogenic nematode Steinernema kraussei by Gotthold Steiner in 1923 (Steiner, 1923). This event will be a unique opportunity to celebrate a century of scientific achievements in the field of nematology and entomology. Join us in celebrating the centenary of the discovery of Steinernema kraussei and contribute to the advancement of knowledge and solutions for sustainable agriculture and pest management.

The congress will be held in Logrono, Spain from Wednesday 10th April, 2024 until Friday 12th of April, 2024. Organized by Raquel Campos-Herrera, this event will take place right before the 2024 meeting of the European Society of Nematologists ( in Cordoba, providing participants with an opportunity to attend both events and maximize their knowledge and networking experiences.

We will bring together renowned experts, researchers, and students from around the world to discuss the latest findings, innovations, and challenges related to entomopathogenic nematodes. Symposia will be organized to include competent experts in the field to summarize existing knowledge and provide valuable insights and perspectives on the history, evolution, and future of nematode research. Poster presentations, workshops and networking opportunities will allow participants to engage with their peers and learn from the best in the field. We look forward to welcoming you to the congress and experiencing an unforgettable celebration of a century of nematology and entomology.

Calle San Millán, 23 - 25, 26004 Logroño, La Rioja

The Palacio de Congresos y Auditorio de La Rioja, better known as Riojaforum, is located in the Parque de la Ribera del Ebro, in an easily accessible area, five minutes walking distance from the center of Logroño. This proximity and accessibility can be extrapolated to the excellent communications available in Logroño.

Logroño is the capital of the Autonomous Community of La Rioja. It is bathed by the Ebro River, which it embraces in its growth and development.
Among the best known virtues of the city, it is worth mentioning the culture of wine, gastronomy, the Camino de Santiago, the Old Town or the character of First Commercial City of Spain.

The size of the city invites visitors to stroll around and enjoy its significant enclaves. The Paseo de El Espolón, the co-cathedral of Santa María de La Redonda; the convent of La Merced, current seat of the regional Parliament; the characteristic Portales street, the church of Santiago El Real, or the church of Santa María de Palacio, are some examples of interest that cannot be missed.

La Rioja
This region, located in the western vertex of the Ebro valley, presents a privileged variety of landscapes, flora and fauna, due to the different geographical characteristics of its natural regions, giving life to the rivers that cross it to fertile plains.

Being the smallest region of Spain, it has taken part in all the historical moments of this one. Occupied by the Romans and Muslims, in the Middle Ages it was the center of disputes between Navarre, Castile and Aragon. In this same period, the Camino de Santiago was a determining phenomenon for its cultural development, becoming a center of influence of the first order, especially through its monasteries, true foci of knowledge and where the first written text in Castilian was forged. Thus, the road is marked by monumental towns of great beauty such as Calahorra, Arnedo, San Millán de la Cogolla, Santo Domingo de la Calzada, and Logroño, already founded by the Romans and nowadays

Special activity: "Jornada de especialización. Nematodos en los viñedos: problemática, desafíos y bioindicadores de la salud del suelo"
Please, visit the link below for additional information:


Dear EPNers We are all very enthusiastic to meet our research community at the meeting in Logrono. For sure a big point of discussion will arise again (as usual): which one has better attacking and defending strategies, the nematode, or the bacteria? Which one is faster, which one is responsible for the final success? Concerning that, we may have the opportunity to see scientists (ladies and gentlemen) from both sides in their display of abilities in the small football field. So, there will be a couple of bacteria vs nematode football matches during the large coffee break. If you are interested to participate and you fulfill these two requirements: i) You like EPN, ii) you are younger than 110 years old, please contact Carlos Molina ( Depending on the number of participants, we will come later with more detailed information.
