Se presenta una recopilación de los resultados de varios proyectos, desarrollados entre los años 2004 y 2015, sobre la presencia de los mosquitos de la familia Culicidae en el entorno de la Devesa y el Racó de l’Olla del Parque Natural de l’Albufera de Valencia (España). Se registró un total de 10 especies pertenecientes a cinco géneros (Aedes, Coquillettidia, Culex, Culiseta y Ochlerotatus), alguno de estos muy característicos de los ambientes donde fueron recolectados. Se tratan diferentes aspectos sobre la diversidad de culícidos, así como del interés ecológico y sanitario de la presencia de los mismos. Destacamos la existencia de la especie Aedes albopictus (Skuse, 1894) en un espacio acotado por viviendas, construidas en los años 1970, y no recolectada en las malladas. A compilation of the results obtained in several projects developed between the years 2004 and 2015 on the presence of the mosquitoes of the family Culicidae in the surroundings of the Devesa and Racó de l'Olla of the Albufera Natural Park of Valencia (Spain). A total of 10 species belonging to five genera (Aedes, Coquillettidia, Culex, Culiseta and Ochlerotatus) were recorded, some of them very characteristic of the environments where they were collected. Different aspects are discussed on the culicid diversity, as well as on the ecological and health interest of the presence of these species. We highlight the presence of the species Aedes albopictus (Skuse, 1894) in a space limited by housing, built in the 1970s, and not collected in the malladas.

The article presents the results of field research conducted in 2020 on the territory of the Ile-Alatau State National Natural Park. As a result of the conducted research, 32 species belonging to 2 families of hemiptera of the infraorder Pentatomomorpha I were identified. Among them, the predominant species composition of the family Lygaeidae is 21 species (66%), and 11 species are known from the family Aradidae (34%). On trophic specialization, they are divided into mycetophagy (11 species), phytophages (21 species, of which politicology – 16 types, wide oligotherapy – 3, narrow oligotherapy – 2). According to the type of food, both taking into account the number and number of species in the complex of hemiptera, phytophages clearly predominate. According to the number of generations per year, the hemiptera of the Ile-Alatau SNNP are divided into 4 groups: acyclic (different stages of development can be found simultaneously throughout the year) – 11 species, monovoltine (one generation per year) - 15 species, bivoltine (two generations per year) – 5 species, polyvoltine (several generations per year) - 1 species. There are 30 species with mesophilic ecology in the study area, only 1 species is hygromesophilus. Among the hemiptera of the Ile-Alatau GNPP, 19 species (61%) overwinter in the imago stage, 11 species (35%) in the imago and larvae stage, and 1 species (4%) in the egg stage.

Flaviviruses are largely transmitted to humans by their arthropod vectors such as mosquitoes or ticks. The dengue virus (DENV) is one of the members of the family Flaviviridae and is the causative agent of dengue fever. In the mosquito vector, DENV enters through viremic blood meal and replicates in the mid-gut. Newly formed virion particles circulate to various mosquito organs and get transmitted to the next host in subsequent bites. Aedes aegypti and Aedes albopictus have intricate immune control to allow DENV production at a sub-pathogenic level. In the mosquito, antimicrobial peptides (AMP) and RNA inference (RNAi) are the two main antiviral strategies used against DENV. Apart from innate immunity, mosquito resident microbes play a significant role in modulating DENV replication. In this review, we discuss different immune mechanisms and preventive strategies that act against DENV in two of its vectors: Aedes aegypti and Aedes albopictus.

Abstract: The Zika virus is a flavivirus spread by mosquitoes. Its primary vectors are the Aedes aegypti and the Aedes albopictus. Before 2007 it sporadically caused benign morbidity. Since 2015, it started spreading “explosively” in America, especially in Brazil. In August 2016 they reported cases from New York and Poland, too. Most of the infections don’t produce any symptoms, but can cause grave complications. The most important lesion is microcephalia that forms in fetuses. Microcephalia’s most serious consequence is mental retardation, which puts great burden on both the family and the society. The viral infection increases the incidence of Guillain-Barré syndrome. This is an acute autoimmune disease which causes demyelination and, in the worst cases, it can also be fatal. Yet we do not possess adequate and specific vaccination nor antiviral therapy, although, since July 2016, the effectiveness of a DNA based vaccine is being tested on humans. More than half of the world’s population lives in areas contaminated by infected mosquitoes so there is a great need for the development of an effective method against the vector mosquitoes. Sadly, even the vector control strategies aren’t effective enough to push back the epidemic. Pregnant or fertile women must take the highest precautions against mosquito bites, especially if they travel to regions ravaged by the epidemic. The safest solution would be to postpone both the trip and the childbearing. In Europe, the vectors aren’t spread enough to cause major threat, except maybe the warmer regions bordered by the Mediterranean Sea. However, it is possible that in the near future other viruses spread by Aedes mosquitoes could appear. Naturally, the travellers and immigrants, who came from endemic regions can also contribute to the spread of the epidemic. Thanks to the changes in global weather, there were reported findings of mosquitoes of the Aedes albopictus species in Hungary, which are slowly invading the continent, although we do not have information about their settlement in the country. The doctors may encounter introduced cases and we do not have to fear the spreading of the epidemic to our country, but in the bordering Slovakia and Slovenia infections have been reported. The future of the Zika virus is yet unpredictable, although looking at the global spread of the Dengue and Chikungunya viruses, a worldwide spread is expectable in the near future. Orv.

From June 1988 to July 1992, non-continuous samples of two species of cartilaginous fish of the family Triakidae were taken in the National Natural Park Gorgona. Stomach contents of 139 individuals of Mustelus lunulatus and 51 individuals of M. henlei were analyzed. These species predate on crustaceans (93,06%), mainly Portunus iridiscens, Squilla panamensis and Hipoconcha panamensis, secondly on mollusks of the family Loliginidae (4,32%) and fishes (2,28%) in a smaller proportion; the remaining 0,34% corresponded to digested material. Nematodes and isopods were found in the stomach contents of these fishes, but we considered them as accidentals and were not included in the analysis.

Dactylorhiza fuchsii (Druce) Soó is a terrestrial orchid belonging to the family Orchidaceae and listed in the Red Book of Kazakhstan, the Baltic region, and the most regions of Russia. D. fuchsii is an interesting object for research in many countries of the world and the study of its biological features and coenotic significance, as well as its distribution and conservation in nature is still relevant today. The article analyzes the most significant biological and coenotic features of D. fuchsii: distribution of the species; features of the structure and dynamics of coenopopulations in different regions; ontogeny; cultivation in Botanical gardens; features of reproduction, including using the method of tissue culture, etc. It reflects the main places of growth in Kazakhstan and the principles of conservation in connection with the classification of the species as rare, subject to protection at the state level. Indicators of D. fuchsii participation in plant communities have been identified on the example of forests of the State National Natural Park “Burabay” (Northern Kazakhstan).
