Achatina fulica or "giant African snail" is an exotic species, considered to be one of the world's hundred most invasive species, causing serious environmental damages. In the present study we report, for the first time, the occurrence of Aelurostrongylus abstrusus infecting A.fulica in the Amazon region. This nematode is described parasitizing mainly the pulmonary system of felines, which causes "aelurostrongilose", also known as feline cardio-pulmonary strongyloidosis. New morphometric data of third stage larvae are presented herein. The present study demonstrated that 40% of all the snails were infected by A. abstrusus. Achatina fulica specimens were collected from three different areas in Manaus namely: rural; east and west areas. The east area presents the highest prevalence of 80%. The large number of A.fulica found in inhabited areas increases the chances of emergent zoonoses, which highlights the need of further studies so as to better control this disease.

O molusco exótico Achatina fulica é classificado como uma das mais preocupantes espécies invasoras do mundo, sendo considerado sério problema ambiental, de saúde pública e econômica, sendo frequentemente encontrado em ambientes antrópicos, e em vários locais do Brasil. Esse molusco pode estar associado ao tipo de ambiente e a sua capacidade de se adaptar, principalmente, em bairros que propiciam locais com muito entulho, lixo e umidade, em que este molusco se adapta com muita facilidade. Este trabalho tem o objetivo de avaliar o grau de conhecimento dos moradores e estudantes do bairro Marajoara II, em Várzea Grande-MT, a respeito do caramujo africano, e dispor soluções para o controle populacional da espécie. Um questionário foi aplicado na comunidade do bairro e na escola Estadual Maria Leite Marcoski para saber o grau de conhecimento dos moradores sobre o caramujo africano. Os resultados da pesquisa apontaram que tanto os entrevistados do bairro, quanto os da escola não têm informações sobre o molusco A. fulica, o que gera a necessidade de palestras educativas com a comunidade escolar e do bairro, para mais informações sobre o assunto.Palavras-chave: Conhecimento Local. Espécie Exótica. Molusco.AbstractThe exotic mollusk Achatina fulica is classified as one of the most troublesome invasive species in the world and is considered a serious environmental, public and economic health problem, often being found in man-made environments, and in many parts of Brazil. This mollusk may be associated with the type of environment and its ability to adapt, especially in neighborhoods that provides places with a lot of garbage, trash and moisture where it fits very easily. This study aims to assess the degree of knowledge of the residents from Marajoara II district of Várzea Grande-MT, about the African snail, and propose solutions to control this species population . A questionnaire was applied to the neighborhood community and the state school Maria Leite Marcoski to know the inhabitants knowledge degree of the African snail. The survey results showed that both respondents in the neighborhood, as the school has no information about the mollusk A. fulica, which creates the need for educational lectures with the school community and neighborhood, for more information on the subject.Keywords: Local Knowledge.

Abstract Isodontia mexicana (Hymenoptera, Sphecidae), a New Invasive Wasp Species in the Fauna of Ukraine Reared from Trap-Nests in the Crimea. Fateryga, A. V., Protsenko, Yu. V., Zhidkov, V. Yu. - Th e North American wasp Isodontia mexicana was found for the first time in Ukraine in trap-nests operated near Pushkino (southern coast of the Crimea) in 2012. Th ree nests contained five cocoons, from which only one adult wasp emerged in 2013, allowing the positive identification; other cocoons were either empty (one) or destroyed by Melittobia acasta (three). Such a find of a newly established invasive species in Ukraine represents the easternmost point in its European range and possibly the most remarkable jump-dispersal event in its distribution.

В статье предлагается концепция жизни и творческого роста В.М. Шукшина сквозь призму тезаурусного и кластерного подходов. Объяснительными «персональными моделями» для интерпретации биографического текста писателя являются кластеры Мартина Идена, Гамлета и Степана Разина. Ранее биографы и литературоведы указывали на важность этих персон для Шукшина, но разрозненно. Впервые предпринята попытка свести указанные персональные модели воедино, в целостный сюжет становления писателя в пространстве культуры. На разных этапах эволюции автора доминирует одна из указанных моделей, последовательно сменяя друг друга, но не вытесняя, а «внахлест». Ранний этап творчества, ориентированный на стратегию Мартина Идена, является попыткой «вписаться» в наличный культурный мейнстрим. Выражено это в следовании поэтике соцреализма. Второй этап подспудно начинается с реабилитации отца Шукшина в 1956 года, когда актуализируется «гамлетовский комплекс», проявляющийся в чувстве вины перед отцом, через стратегию утаивания подлинного «я», мотивы чудаковатости. Третий этап связан с личностью реального исторического лица, Степана Разина, и выражается в открытом протесте против власти. Все важные для В.М. Шукшина поведенческие модели объединены мотивом одинокого противостояния враждебному социуму и имеют трагический финал, что обусловило ранний уход писателя и порождение мифов о насильственном характере его смерти. В.М. Шукшин одновременно был фигурой неординарной и типичной, что позволило его биографии стать «персональной моделью» для последующих авторов, выходцев из сельской глубинки. The article proposes the concept of life and creative growth of V.M. Shukshin through the prism of the thesaurus and cluster approach. The explanatory "personal models" for interpreting the biographical text of the writer are clusters of Martin Eden, Hamlet and Stepan Razin. Earlier, biographers and literary critics pointed out the importance of these people for Shukshin, but it was scattered. For the first time, an attempt was made to bring these personal models together into an integral plot of the formation of the writer in the space of culture. At different stages of the writer’s evolution, one of these models dominates, successively replacing each other, but not crowding out, but “overlapping”. The early stage of creativity, focused on Martin Eden’s strategy, is an attempt to “fit in” the current cultural mainstream. This is expressed in following the poetics of socialist realism. The second stage implicitly begins with the rehabilitation of Shukshin’s father in 1956, when the “Hamletian complex” is actualized. It is manifested in a sense of guilt towards his father, the strategy of concealing the true “I”, eccentricities. The third stage is connected with the personality of a real historical person, Stepan Razin, and is expressed in an open protest against the authorities. All important for V.M. Shukshin's behavioral models are united by the motive of a lonely confrontation with a hostile society and have a tragic ending, which led to the early departure of the writer and the generation of myths about the violent nature of his death. V.M. Shukshin was an extraordinary and typical figure at the same time. That allowed his biography to become a “personal model” for subsequent authors who came from the rural outback.

The article presents the results of research of the using light traps (luminescent lamp Actinic 6W) for collecting Coleoptera in the Saratov city. Entomological material was collected by the second author in the period from 1.06 to 2.10.2019. In 2019, 52 species of Coleoptera of 22 families from different ecological groups were recorded. A relatively high proportion of adventitious species remains in 17.3– 30.7% of the presented fauna was presented. For two years the 14 species of alien and cryptogenic Coleoptera species were observed, that is 24.5% of the adventive fauna of the Saratov Province. Among invasive species Attagenus smirnovi, Stegobium paniceum, Atomaria lewisi, Harmonia axyridis, Gnatocerus cornutus, and Orchestes steppensis were record for the first time in 2019. It to use bringing on light as one of the available and low-cost ways to identify alien and cryptogenic organisms in urban areas is recommended.

This paper reviews recent work examining two topics of economic research vital for invasive species policy—integration and valuation. Integration requires bioeconomic models that blend invasive biology with economic circumstances and the feedback loops between the two systems. Valuation requires nonmarket valuation associated with human and environmental damages posed by invasive species. We argue for a second-level of integration in invasive species economics—valuation based on integration models. Policy prescriptions based on integration models need valuation work; valuation surveys need integration models—the two are complements. Valuation could be enhanced with integration in mind; integration could be made better with valuation in mind. An example from blending the two research areas is presented and its merits demonstrated.

Among the principal causes producing detrimental effects on global biodiversity are introductions of alien species. Very few attempts to control introduced amphibians and reptiles in Middle America (Mexico and Central America) can be identified, so listings are provided for 24 exotic species, 16 translocated species, and 11 species that were removed from the introduced species listing because of lack of substantiating evidence that they are from established populations. Biosecurity methods are also identified that can be applied for preventing, controlling, and managing introduced and especially invasive species.

Angiostrongylus costaricensis is a nematode parasitic of rodents. Man may become infected by ingestion of the third stage larvae produced within the intermediate hosts, usually slugs from the family Veronicellidae. An epidemiological study carried out in a locality in southern Brazil (western Santa Catarina State) where these slugs are a crop pest and an important vector for A. costaricensis has documented for the first time the natural infection of Deroceras laeve with metastrongylid larvae. This small limacid slug is frequently found amid the folds of vegetable leaves and may be inadvertently ingested. Therefore D. laeve may have an important role in transmission of A. costaricensis to man.
