NEW DATA ON DISTRIBUTION OF CALIAESCHNA MICROSTIGMA (SCHNEIDER, 1845) (ODONATA: AESHNIDAE) IN SERBIA

2023-08-02T01:37:19+02:00

Caliaeschna microstigma is a species distributed mainly in the eastern Mediterranean, from Croatia in the west to northern Iran and Caucasus in the east. Until this study, it was reported only from a few localities in Serbia, which are located in far south. Here we have summarized all available data and presented new data on the distribution of C. microstigma in Serbia. The Eastern Spectre was detected at seven new localities (four during field study and three from publicly available databases), extending its current range in Serbia by more than 120 km to the north.

DISTRIBUTION AND HABITAT OF CARABUS HUNGARICUS (COLEOPTERA: CARABIDAE) IN SERBIA AND RECOMMENDATION FOR MONITORING

2023-08-02T01:37:19+02:00

The distribution of Carabus hungaricus in Serbia has not been summarized so far. There are only a few published records of this beetle in Serbia. Due to new findings, it was necessary to update the distribution of this species in Serbia. Recent field research revealed that the largest suitable habitat is the Deliblato Sands in the South Banat District, where this species is common. Other important areas are located near the Romanian border in the vicinity of the city of Vršac and near Mužlja (in the neighborhood of the city of Zrenjanin, Central Banat District), where the northernmost population in Serbia is located. In addition to this overview of distribution, we propose monitoring methodology for C. hungaricus. We believe that regular monitoring can bring the necessary attention to the disappearing steppe habitats and that the results can help to manage them appropriately in the future.

NEW RECORDS OF ACONTIA CANDEFACTA (HUBNER, 1831) (LEPIDOPTERA: NOCTUIDAE) FROM CROATIA, SLOVENIA AND BOSNIA AND HERZEGOVINA

2023-08-02T01:37:19+02:00

In this paper, we present new records of Acontia candefacta in Croatia, Slovenia and Bosnia and Herzegovina. From the time of the first records in Croatia in 2019, the species has spread across much of the country and has also become very common in its northern regions. The first observations have been reported for Slovenia and Bosnia and Herzegovina. In Slovenia, the species has been recorded at two localities near the Croatian border, while in Bosnia and Herzegovina, the species has been recorded in two far-apart regions, indicating that it is more widespread in the country.

THE SUBLETHAL EFFECTS OF FIVE INSECTICIDES ON HABROBRACON HEBETOR SAY PARASITISM ON EPHESTIA KUEHNIELLA ZELLER LARVAE BASED ON PHENOLOXIDASE ENZYME ACTIVITY

2023-08-02T01:37:19+02:00

Ephestia 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 (F_{5, 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.

HABITAT PREFERENCES AND ABUNDANCE OF THE DOLICHOPODIDAE (DIPTERA) FROM INNER WEST ANATOLIA

2023-08-02T01:37:19+02:00

In 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.

GUIDELINES FOR SAMPLING AND PRESERVATION OF BLACK FLIES (DIPTERA: SIMULIIDAE) – AN ATTEMPT TO STANDARDIZE FIELD AND LABORATORY PROCEDURES

2023-08-02T01:37:19+02:00

This paper provides guidelines for sampling and preserving black flies (Diptera, Simuliidae), aiming to standardize field and laboratory procedures. The authors detail the methods for processing black fly samples, from collection to identification, for each stage. They also propose a sampling protocol that considers various environmental factors influencing species distribution and abundance. The paper is based on the authors' personal experience and aims to contribute to a broader understanding of black fly ecology and taxonomy.

FIRST RECORDS OF PLINACHTUS IMITATOR (REUTER, 1891) (HETEROPTERA: COREIDAE: COREINAE) IN CROATIA, BOSNIA & HERZEGOVINA AND MONTENEGRO, WITH NOTES ON NEW HOST-PLANT RECORDS

2023-08-02T01:37:18+02:00

The paper mentions the first findings of the bug Plinachtus imitator (Reuter, 1891) in Croatia, Bosnia and Herzegovina and Montenegro. All the findings were recorded in localities along the Adriatic coast, most often on Pistacia lentiscus, a plant that was already known as a host. Plinachtus imitator was recorded for the first time on a new host plant - Pistacia terebinthus in Trsteno, Croatia.
