ORTHOPTEROIDEA FAUNA OF LESOTHO

Grzegorz Kopij — Mon, 26 Feb 2024 00:00:00 +0100

In total, 134 species in 110 genera and 20 families of the former cohort ‘Orthopteroidea’ were recorded in Lesotho. All records (localities, data of collection, information source) in Lesotho are listed for each species. In southern Africa, the numbers are higher by an order of magnitude, which may indicate how much of the Lesotho fauna is unrecorded. The most speciose order of ‘Orthopteroidea’ in Lesotho is Orthoptera (93 species within 77 genera), and the most speciose family within this order is Acrididae (62 species within 45 genera). All families of ‘Orthopteroidea’ recorded in southern Africa are listed, and the number of species and genera are given separately for the whole subcontinent and Lesotho to elucidate how much is known about Lesotho fauna. At least 10 species of ‘Orthopteroidea’ are endemic to Lesotho: Hyposphaeria guillarmodi, Oxypilus inscriptus, Conocephalus basutoanus, Gymnogryllus politus, Basutacris inflatifrons, Eremidium basutho, Qachas fastigiata, Sphingonotus basutensis, Xiphocera fissa, and Brachyphymus basuto.

Dilian Georgiev, Stoyan Beshkov, Ana Nahirnić-Beshkova — Mon, 01 Jul 2024 00:00:00 +0200

The study presents new records of Psocoptera (Insecta) species from Albania, Bulgaria, and Serbia, enhancing the understanding of barkfly diversity in the Balkans. Noteworthy findings include the first records of Hemineura dispar Tetens, 1891 (species complex) from Albania, Mesopsocus immunis (Stephens, 1836) from Albania and Serbia, and Amphigerontia intermedia (Tetens, 1891) from Bulgaria. Additionally, Ptycta nadleri Galil, 1981, a species with limited distribution, was documented in Bulgaria, extending the known range of this species.

ARADIDAE (HETEROPTERA) IN THE ENTOMOLOGICAL COLLECTION OF THE NATURAL HISTORY MUSEUM IN BELGRADE

Ljiljana Protić, Aleksandar Stojanović — Mon, 01 Jul 2024 00:00:00 +0200

The 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.

NOTES RELATED TO IMMATURE OVARY OF THE FOREST CATERPILLAR HUNTER ADULT CALOSOMA SYCOPHANTA (LINNAEUS, 1758) (COLEOPTERA: CARABIDAE)-LIGHT AND ELECTRON MICROSCOPY STUDIES

Nurcan Özyurt Koçakoğlu, Hicret Arslan, Selami Candan — Wed, 05 Jun 2024 00:00:00 +0200

Calosoma 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

Tue, 23 Apr 2024 00:00:00 +0200

The 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

Fri, 21 Jun 2024 00:00:00 +0200

The 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.

Aleksey S. Sazhnev — Thu, 27 Jun 2024 00:00:00 +0200

The first record of Heterocerus woodruffi Pacheco, 1975 (Coleoptera: Heteroceridae) in Peru is presented. The discovery raises the number of Heteroceridae species in the Peruvian fauna to six. H. woodruffi has since been recorded in Argentina, Bolivia, Brazil, Paraguay, and now in Peru. The article features images of the male H. woodruffi and its aedeagus.
