HABITAT PREFERENCES AND ABUNDANCE OF THE DOLICHOPODIDAE (DIPTERA) FROM INNER WEST ANATOLIA
Get PDFIn this study, the habitat preferences and abundance of Dolichopodidae species in the Inner West Anatolia (Afyonkarahisar, Kütahya and Uşak) were investigated by means of a hand net during the years 2009 to 2011. A total number of 4,327 specimens were gathered belonging to 77 species. The majority of identified species in the study area prefer moist and shaded habitats such as fenlands, reedbeds, moist coniferous woodland and moist grasslands, depending on habitat preference. Almost 45 % of the total number of collected specimens belonged to one species (Syntormon pallipes). Other abundant species were Hydrophorus balticus and Poecilobothrus regalis
APHIDIUS NEES (HYMENOPTERA, BRACONIDAE, APHIDIINAE) IN SERBIA: KEY TO SPECIES IDENTIFICATION INCLUDING PARASITOID – APHID HOST LIST
Get PDFThis study offers a comprehensive guide to the identification of 34 Aphidius species that were found in the territory of Serbia. Also, for all Aphidius species, a total of 97 aphid hosts were represented. Aphidius linosiphonis Tomanović & Starý and Aphidius balcanicus Tomanović & Petrović were described from Serbia. Aphidius ericaphidis Pike & Starý and A. banksae Kittel are allochthonous species in Serbia of North American and Asian origin, respectively. For both allochthonous species, the first records for the fauna of Europe were from Serbia
A NEW RESIDENT OF BELGRADE (SERBIA), THE MEDITERRANEAN SPIDER ZOROPSIS SPINIMANA (DUFOUR, 1820)
Get PDFA Mediterranean synanthropic spider species, Zoropsis spinimana (Dufour, 1820), was recently found in Belgrade and recorded as a new member of Serbian fauna. Several individuals of both sexes and juveniles were caught or observed. Pregnant females and their cocoons were also observed. According to our findings, this spider has established a small population in the city. Considering that this species has been recognized as a successful colonizer and could be identified by the general public, the first “Citizen Science” approach in Serbia was applied. An invitation to participate was made via social media. The manuscript includes photos contributed from other parts of the country. This confirmed our suspicion that Z. spinimana is to be found in more than one place in Serbia, which requires further investigation. This paper aims to report this species as a new member of the national and synanthropic fauna and to present the benefit of using “Citizen Science” data
THE SUBLETHAL EFFECTS OF FIVE INSECTICIDES ON HABROBRACON HEBETOR SAY PARASITISM ON EPHESTIA KUEHNIELLA ZELLER LARVAE BASED ON PHENOLOXIDASE ENZYME ACTIVITY
Get PDFEphestia kuehniella is an important cereal pest and Habrobracon hebetor is its efficient biocontrol control worldwide. The enzyme phenoloxidase is one of the major components of the insect immune system. This enzyme catalyzes the quinones and other reactive intermediates to reduce parasitoid invasion. In this study, the effects of five commercial insecticides in Iran on the parasitism percentage of H. hebetor and on the activation of phenoloxidase in the hemolymph of host larvae as an important indicator were investigated. The results showed that the percentage of parasitism was significantly lower in insecticide treatments compared to the control (F5, 42= 6.471). There were significant differences in total protein content among the control and insecticides treatments, as well as in the phenoloxidase activity in the host larvae. Accordingly, the highest activity was in the control (0.3924±0092 μM/min/mg protein) and the lowest when larvae were treated with propargite (0.1927±0.0169 μM/min/mg protein). The results confirmed that the insecticides palizin and buprofezin do not have serious negative effects on H. hebetor parasitism when combined in integrated pest management
ADDITIONAL SPIDER RECORDS FROM MT. FRUŠKA GORA (SERBIA) WITH A FIRST INSIGHT INTO WINTER SPECIES
Get PDFMonitoring spiders with pitfall traps often only includes data collected during the vegetation period. Herein, we present the results of long-term sampling at Erdelj, Fruška Gora Mountain, over 19 months in 2011/2012. Special emphasis was placed on the winter period. At three sampling sites, a meadow, an area of shrubs and a deciduous forest, 1113 adult spiders of 116 species were identified. Thirty-four species are new records for the mountain; six of them are new to Serbia. The meadow yielded the highest number of species (59), with a high proportion (40%) of species collected only in this habitat type. Eleven species were found to be active mostly or exclusively in winter. Four of them were so-called rare spiders and two of them are new records for Serbia. Of all recorded species, five are on the list of strictly protected spiders in Serbia and could be used as an additional argument for environmental protection
SYMBIOCLADIUS RHITHROGENAE (ZAVREL, 1924) (DIPTERA: CHIRONOMIDAE): A NEW FINDING FOR THE ENTOMOFAUNA OF SERBIA
Get PDFDuring hydrobiological research on the territory of Serbia in 2011 and 2012, the species Symbiocladius rhithrogenae (Zavrel, 1924) (Diptera: Chironomidae) was found in the Rača stream at three localities. Our study is the first record of this parasite in Serbia. The parasite only infected the larvae of Rhithrogena cf. semicolorata (Ephemeroptera: Heptageniidae) and was not found in any other species from the family Heptageniidae. This study contributes to the knowledge about the diversity of the family Chironomidae in Serbia
PARASITOIDS OF CHLOROPHORUS DAMASCENUS (CHEVROLAT) (COLEOPTERA: CERAMBYCIDAE) IN VINEYARDS OF SOUTHEASTERN ANATOLIA REGION
Get PDFThe survey was conducted during the period 2019-2022 in the vineyard areas of Diyarbakır, Mardin, Elazığ, Batman, and Şanlıurfa provinces. Studies were carried out to identify parasitoids of the wood-tissue pest Chlorophorus damascenus, which has recently become a problem in vineyard areas that are old and exposed to stress factors. Dolichomitus populneus (Ratzeburg, 1848) (Hymenoptera: Ichneumonidae), and Iphiaulax impostor (Scopoli, 1763) (Hymenoptera: Braconidae) were obtained from Chlorophorus damascenus. C. damascenus was a new host for D. populneus
MOLECULAR CHARACTERIZATION OF MAJOR VECTOR MOSQUITOES OF BANGLADESH
Get PDFMosquito-borne diseases are considered major contributors to vector-borne diseases, threatening more than eighty per cent of the global population. Pest management depends on proper identification techniques. The barcode region of the cytochrome oxidase subunit I gene of mitochondrial DNA has recently been proposed as a systematic tool, functional in taxonomy and evolutionary study for species definition. This work is the first attempt to identify the main vector mosquito species from Bangladesh based on the MT-COI gene. Eleven vector mosquitos were identified. AT content (69%) was found to be higher than GC content (31%) at the COI barcode region of the mosquito. The interspecific genetic divergence range of medically important mosquitoes was 0.01-0.21. Haplotype analysis revealed that Mansonia annulifera diverged highly from its immediate ancestor by the highest mutational steps (59). Phylogenetic analysis indicated that species belonging to the same family were in the same major clade. Overall, our findings contribute to a better method of identifying major vector mosquito species by COI genes and for implementing management measures against mosquito pests in Bangladesh
