NOTES RELATED TO IMMATURE OVARY OF THE FOREST CATERPILLAR HUNTER ADULT CALOSOMA SYCOPHANTA (LINNAEUS, 1758) (COLEOPTERA: CARABIDAE)-LIGHT AND ELECTRON MICROSCOPY STUDIES
Get PDFCalosoma sycophanta (Linnaeus, 1758) (Coleoptera: Carabidae) is one of the most important predators of pine processionary moth, Thaumetopoea pityocampa (Denis & Schiffermüller) (Lepidoptera: Thaumetopoeidae) larvae and pupae. Therefore, it is an important species in biological control. Relatively few studies have focused on the female reproductive system in C. sycophanta. We use light and electron microscopy to study the female reproductive anatomy and histology of C. sycophanta. The female reproductive organs of C. sycophanta consist of paired ovaries, lateral oviducts, a common oviduct, and a genital chamber. Each ovary is formed of about 12 polytrophic meroistic ovarioles. In the longitudinal section of the ovary, it was noticed that the vitellarium region located after the germarium contains egg chambers that develop in a linear order, and it is distinguished that each chamber consists of an oocyte and nurse cells formed by incomplete cytokinesis from the same germ cell. The ovary connects to the lateral canal through a pedicel, and within each chamber, there's an oocyte alongside 16 food cells, all encircled by follicular cells. The epithelium of the pedicel and lateral oviduct is formed of monolayered cells overlaid by a muscle layer. The intima layer is distinguished on the side of the epithelium facing the lumen. Spines are seen in the intima. The purpose of this study is to describe ovarian histoanatomy in C. sycophanta and compare it with other coleopteran species, including Carabidae

THE SMALL CHINA-MARK CATACLYSTA LEMNATA (LINNAEUS, 1758) (LEPIDOPTERA: CRAMBIDAE: ACENTROPINAE) IN SERBIA
Get PDFThe Western Palaearctic moth Cataclysta lemnata (Linnaeus, 1758) is considered one of Europe’s most common water moths. However, there are limited data regarding the larval stages, particularly in eastern and southeastern Europe. During the 2017-2021 aquatic macroinvertebrate survey, C. lemnata was detected at seven sites in the Pannonian region of Serbia. All sightings were of the larval/aquatic phase and originated from both heavily polluted habitats and relatively unpolluted waterbodies. A consistent feature at all sites is duckweed (Lemna sp.), confirming the preference of C. lemnata for this plant. Our findings contribute to a better understanding of the presence of this species in the region and suggest that it may be more abundant in its various aquatic habitats. As the adult stages are simpler to identify, and with the advent of public online databases (Alciphron, biologer.rs), there have been multiple records of adult moths in recent years. Regarding the aquatic stages, there is a need for more comprehensive surveys with a primary emphasis on suitable habitats throughout the region and the use of molecular methods for the identification of early larval stages would be beneficial
FIELD EVALUATION OF NEW STRATEGIES IN INTEGRATED MANAGEMENT OF RICE STRIPED STEM BORER (CHILO SUPPRESSALIS) IN RICE FIELDS
Get PDFThe present study comprised three separate experiments to evaluate the effectiveness of biocompatible strategies in controlling Chilo suppressalis Walker in rice fields. The results of the first experiment showed that the lowest number of infested tillers, number of larvae, pupae, and dead hearts was related to the oil-spraying treatment with an interval of 7 days. The results of the second experiment in part 1 showed that mineral oil, 5% kaolin, mineral oil + kaolin, and diazinon caused 79.20, 58.40, 83.21, and 77.27% reductions in dead heart and 77.86, 69.47, 88.04, and 93.13% reductions in the white head in rice plants and 72.00, 50.74, 76.89 and 97.37% reduction in C. suppressalis ovipositing, respectively, compared to the control. According to the results of the second experiment in Part 2, 3% mineral oil, 5% kaolin, 5% kaolin + trap crop, and 3% mineral oil + trap crop had a 57.50, 64.67, 96.47, and 92.83% repelling effect, respectively, against adult rice striped stem borer (RSSB) insects and reduced oviposition. These treatments reduced the number of dead hearts by 66.07, 76.75, 89.45, and 85.64% and the number of whiteheads by 57.80, 65.12, 73.90, and 69.02 compared to the control. The results of the second experiment in Part 3 showed that mineral oil, kaolin 5%, and mineral oil + kaolin caused 42.83, 64.24, and 78.59% reductions in the number of infested tillers, respectively, compared with the control. In the third experiment, mineral oil and mineral oil + kaolin reduced the number of C. suppressalis larvae by 80.65 and 90.32%, respectively. These treatments also resulted in 55.56 and 75% in dead hearts and 73.29 and 79.45% in whiteheads, respectively. The findings show that mineral oil and kaolin can be applied individually and in combination with each other or in combination with trap cropping to control C. suppressalis
NEW RECORDS OF THE INVASIVE SPECIES SCELIPHRON CAEMENTARIUM (DRURY, 1773) (HYMENOPTERA: SPHECIDAE) IN ADDITIONAL COUNTRIES AND REGIONS
Get PDFSceliphron caementarium (Drury, 1773) is a Nearctic mud-dauber wasp, accidentally introduced in various parts of the world. The occurrence of this species was first recorded in Algeria, Turkey, Curaçao, Colombia, and Vanuatu, as well as the island of Crete and the archipelago of Tremiti Islands. Moreover, an additional 27 regions across several countries and 11 new islands have been identified as locations where the species occurs
ARADIDAE (HETEROPTERA) IN THE ENTOMOLOGICAL COLLECTION OF THE NATURAL HISTORY MUSEUM IN BELGRADE
Get PDFThe Entomological Collection of the Natural History Museum contains specimens from 19 species of the family Aradidae from the Palearctic region and 14 species from the Neotropical and Oriental regions. There are 16 species documented in Serbia, 14 of which are found in the collection. This paper presents three new species for Serbia: Aradus betulinus Fallén, 1807, Aradus brenskei Reuter, 1884, and Aradus somcheticus Kiritshenko, 1913. Aneurus laevis (Fabricius, 1775) was recorded on Mt. Cer after a hiatus of 100 years of being recorded in Serbia
NEW RECORDS OF ACONTIA CANDEFACTA (HUBNER, 1831) (LEPIDOPTERA: NOCTUIDAE) FROM CROATIA, SLOVENIA AND BOSNIA AND HERZEGOVINA
Get PDFIn 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

DESCRIPTION OF SURFACE STRUCTURE OF EGGS AND FIRST INSTAR LARVAE OF AGAPANTHIA OSMANLIS REICHE & SULCY (COLEOPTERA: CERAMBYCIDAE): BASED ON SCANNING ELECTRON MICROSCOPY
Get PDFMorphology of eggs and first instar larvae of Agapanthia osmanlis Reiche & Saulcy, 1858 (Coleoptera: Cerambycidae) are described for the first time, with illustrations of the structural features obtained using light and scanning electron microscopy (SEM). A. osmanlis feeds only on hosts in the Dipsacaceae family and collected on Cephalaria procera Fish & Lall. (Dipsacaceae) from Bayburt (Kop Mountain Pass, Turkey). The female lays single eggs inside the stalks of C. procera, where the larva feeds internally. The egg is cylindrical, white, dorsally wide, narrower toward the front and back, and rounded anteriorly and posteriorly. The egg is 3.10-3.80 (3.35) mm long and 0.45-0.85 (0.58) mm wide. Under the dissection microscope, the chorion appears to be smooth, but in scanning electron microscope (SEM) magnifications, the chorion is covered with chorionic spines except for the anterior micropylar region. Each egg possesses a knob-like micropylar process at one end. Newly emerged larvae of A. osmanlis are cylindrical, C-shaped after leaving their galleries, whitish-grey, and legless
FIRST RECORDS OF PLINACHTUS IMITATOR (REUTER, 1891) (HETEROPTERA: COREIDAE: COREINAE) IN CROATIA, BOSNIA & HERZEGOVINA AND MONTENEGRO, WITH NOTES ON NEW HOST-PLANT RECORDS
Get PDFThe 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
