Integrated Pest Management Education: a Video-Game to Improve Management of Drosophila suzukii, Soft-Skin Fruit Pest.

The transition from the conventional global agriculture to an agroecological model poses a teaching and learning challenge to facilitate the wide variety of practices and the many biological processes involved. Games, such as board games, video-games, or mobile apps, are elements that may be used for teaching agroecology, environmental education, or animal conservation. Here, we present a video-game designed to contribute to integrated pest management education. The Spotted-Stop-It video-game is a single-player game which encourages participation, disseminates knowledge on the pest problem and its potential solutions (i.e., harvest frequency, sanitation, and management of alternative non-crop plants), and highlights the importance of good practices from an agroecological perspective at the farmer scale. In a farm-tech regional fair, we presented the game to its users and performed a simple retrospective survey. The survey results showed that most participants did not know about the fly prior to playing the game (34 ind., 68%), but were able to recognize the species among other flies after playing (23 ind., ~ 65%). Also, 21 individuals correctly responded about the effects of this pest on soft-skin fruits ("the fly lays eggs inside the fruit"). The training of future generations on new insect invasions and IPM practices with elements of their own environment may prove to be important to transmit concepts and practices at the service of sustainable crop protection.

Helminth communities of two populations of Myotis chiloensis (Chiroptera: Vespertilionidae) from Argentinean Patagonia.

Most of the studies on chiropteran endoparasites in Argentina come from the Central and Northeast regions of the country, and there is only one parasitological study of bats from the Argentinean Patagonia. The aim of this study is to describe the helminth fauna of 42 Myotis chiloensis, comparing the composition and the structure of the endoparasite communities between two populations, inhabiting different environments in Andean humid forest and the ecotone between forest and Patagonian steppe. A total of 697 helminths were recovered from 33 bats: five species of trematodes, Ochoterenatrema sp., Paralecithodendrium sp., Parabascus limatulus, Parabascus sp., and Postorchigenes cf. joannae, two species of cestodes, Vampirolepis sp. 1 and Vampirolepis sp. 2, and three species of nematodes, Allintoshius baudi, Physaloptera sp., and Physocephalus sp. All the helminths, but Physocephalus sp., were recovered from the small and large intestine. This is the first survey of M. chiloensis' helminth fauna. All the species, but A. baudi, represent new records of helminths in Patagonian bats. There were differences of parasite species richness between localities and both bat populations share almost half of the endoparasite species. Different preferences for intestinal regions were found for three species of trematodes in the bats from the site in the humid forest. Myotis chiloensis serves as both a definitive and intermediate host for endoparasites in the Patagonian ecosystem.

[Responsible ownership of dogs and human health in neighborhoods of San Carlos de Bariloche, Argentina]. / Tenencia responsable de perros y salud humana en barrios de San Carlos de Bariloche, Argentina.

Human relationship with dogs associates with numerous and varied benefits on human health; however, it also presents significant risks. The goal of this study was to describe demographic parameters and characteristics of dog ownership with possible implications on human health and to evaluate the prevalence of dog bites and traffic accidents due to dogs. Interviews were conducted in the neighborhoods of Nuestras Malvinas and Nahuel Hue in San Carlos de Bariloche. The percentage of homes with at least one dog, the average number of dogs per home, the prevalence of dog bites and traffic accidents due to dogs and the general awareness of the population on dog transmitted zoonoses were estimated. Regarding ownership characteristics, the degree of sterilization, vaccination and parasite control and the percentage of dogs allowed to roam freely in public places were evaluated. A total of 141 interviews were conducted; 87% of the households had at least one dog, with an average of 2.2 dogs. In 26% of the households someone had suffered a traffic accident caused by dogs and in 41% someone had been bitten. Antiparasite treatment was administered to 83% of the dogs in the last 12 months, on average 1.4 times (recommended 6 times), 51% were sterilized, 55% were allowed to roam freely. This study shows a disturbing situation regarding the canine population of the evaluated neighborhoods. The number of dogs allowed to roam freely and the low level of parasite control and sterilization provide suitable conditions for the spread of zoonoses.

La relación entre el hombre y el perro se asocia a numerosos y variados beneficios sobre la salud humana; sin embargo también presenta importantes riesgos. El objetivo de este trabajo es describir parámetros demográficos y características de la tenencia de perros con implicancias sobre la salud humana y evaluar la prevalencia de mordeduras y accidentes de tránsito causados por perros. Se realizó una encuesta en los barrios Nuestras Malvinas y Nahuel Hue de San Carlos de Bariloche. Se estimó el porcentaje de viviendas con al menos un perro, la media de perros por vivienda, la prevalencia de mordeduras de perro y de accidentes de tránsito causados por perros y el conocimiento de la población sobre zoonosis transmitidas por perros. Respecto de la tenencia, se evaluó el grado de esterilización, vacunación y desparasitación y el porcentaje de perros con libre acceso a la calle. Se realizaron 141 entrevistas. En 87% de las viviendas había al menos un perro (promedio 2.2 perros/vivienda). En 26% de las viviendas alguien había sufrido un accidente de tránsito causado por perros y en 41% alguien había sido mordido. El 83% de los perros fueron desparasitados en los últimos 12 meses, en promedio 1.4 veces (óptimo: 6 veces/año), 51% estaban esterilizados, 55% tenían libre acceso a la calle. Este estudio muestra una situación preocupante respecto de la población canina de los barrios evaluados. El número de perros sueltos en la calle y el bajo nivel de desparasitación y esterilización proveen condiciones ideales para que se propaguen zoonosis.
