Résumé :

Twelve species of biting midges of the genus Atrichopogon reported by Kieffer (1912, 1916a,b, 1921, 1922) from Taiwan are redescribed, illustrated and/or interpreted. They are included in the subgenus Psilokempia Enderlein (A. myrmedon Kieffer, 1912) and in the subgenus Atrichopogon s. str. (A. argus Kieffer, 1916, A. flaviceps Kieffer, 1912, A. haemorrhoidalis Kieffer, 1921, A. insularis Kieffer, 1921, A. minimus Kieffer, 1916, A. pruinosus Kieffer, 1921 and A. ruber Kieffer, 1916). Five new synonyms are proposed for the following species: A. ruber Kieffer, 1916 (=A. formosanus Kieffer 1918), A. myrmedon Kieffer, 1922 (=A. quadrispinosus Remm, 1993; =A. pectinacaudalis Yu & Yan, 2006), A. insularis Kieffer, 1921 (=A. citrinipes Kieffer, 1922) and A. flaviceps Kieffer, 1912 (=A. mendax Kieffer, 1922, as var. of A. flaviceps). Atrichopogon crispantis Liu, Yan & Liu, 1996 is resurrected from synonymy with A. insularis Kieffer, 1921. Atrichopogon rufescens Kieffer, 1921 is recognized as a nomen dubium, while A. atriceps mentioned by Blech & Rohlfien (1987) is considered a nomen nudum. A key to the species described by Kieffer from Taiwan is provided.

Résumé :

Diabetes Mellitus (DM) is one of the major health problems in the world and Indonesia. The prevalence is more increasing and also shows the trend of events is shifting to young age. Diabetes mellitus treatment requires high costs and also a lifetime. Most of the people of Indonesia still use traditional methods of treatment, especially herbs from various biological substances that are available in the environment. Undur-undur (myrmeleon sp.) is believed to have the effect of anti-hyperglycemia, and also anti-viscosity. The aim of this study was to determine anti-hyperglycemia and anti-viscosity of myrmeleon sp. extract in diabetic rats. The design of study is randomized experiment. Diabetic rats were induced by streptozocin 100mg/ kg BW intraperitoneal. Fifty rats were divided into 2 groups administered by Myrmeleon sp. extract dose 0,01ml/ 200 gram BW (100%) and 0,005ml/ 200 gram BW (50%). Myrmeleon sp. shows the effect of anti-hyperglycemic and anti-viscosity in diabetic rats. There was a difference between 50% and 100% doses. The effect of anti-hyperglycemia and anti-viscosity occurs after the second day. Conclusion: the extract of myrmeleon sp. could be considered as one of the traditional treatments of diabetic patients.

Résumé :

Negative effects on health will occur in excessive use of paracetamol. The main objective of this study was to determine the hepatoprotective activity of Propolis Trigona spp., Hibiscus sabdariffa, and Myrmeleon sp. in rats induced by paracetamol. The study was conducted on 36 Sprague Dawley rats with 6 rats in each group. Group 1 (normal control), group 2 (positive control, temulawak 42.86 mg/kg BW), group 3 (negative control), group 4 (infusion of Myrmeleon 10 mg/kg BW), group 5 (propolis extract 0.02 ml/kg BW), and group 6 (Hibiscus sabdariffa infusion 0.02 ml/kg BW). Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations were determined spectrophotometrically and microscopically for liver histopathology. The results showed that during three weeks of treatment with Propolis Trigona spp., Hibiscus sabdariffa, and Myrmeleon sp. in rats, this treatment could decrease ALT and AST activity as the positive control. The ALT activity values of the three materials were 69.26, 51.00, 51.00, 43.67, U/I with AST values of 110.29, 97.33, 91.00, 91.33 U/I. Based on Duncan's test, there were significant differences between all treatments with negative and positive control groups. Likewise, with the histopathological scoring results, the negative control was found to be significantly different from all treatments. Therefore, treatment with propolis Trigona spp., Hibiscus sabdariffa, and Myrmeleon sp. may have hepatoprotective benefit.

Résumé :

Abstract The remarkable diversity of antlions in the Afrotropical region is counterbalanced by the scarce knowledge of their biology and ecology. In particular, their larval stages are largely unknown and the morphology of African pit-building species was never investigated in detail. The larvae of three pit-building species attaining a wide distribution across the whole continent, namely Myrmeleon caliginosus, M. obscurus and M. quinquemaculatus are described, illustrated and compared with congeners for the first time. Moreover, M. caliginosus is reported for the first time from Namibia, notably extending the known range of this antlion, with implications on the taxonomy and the identification of African Myrmeleon species. The larvae of these three species highlight the overall conservative morphology across the whole genus, differing in relatively minor characters such as size, proportions, pattern and chaetotaxy.

Résumé :

AbstractA bronze olpe in which a hoard of cyzicenes was found in 2003 in Myrmekion is discussed. The vessel belongs to a group of bi-conical bronze olpai singled out by Thomas Weber as Type III. B and should be dated to the first half, or possibly the second quarter, of the 5th century BC (the hoard in the olpe was hidden in the second quarter of the 4th century BC). Further the hoards of coins in bronze olpai and hoards of cyzicenes in bronze vessels are discussed, including the find of 1989 during excavations at Vaste in Messapia of a similar bronze olpe, where the core of the hoard consisted of coins minted in Tarentum between 272 and 235 BC. It is highly likely that certain similarities with regard to the long gaps between the concealment of the hoards in the bronze olpai and the date of the manufacture of the actual vessels mean that in both cases the hoards can be linked with temple treasuries, in which olpai figured prominently.

Résumé :

2016 - 2017
This dissertation aims to investigate the most relevant passages of Myrmedon, focusing on the analyse of a not well-known poem of Giovanni Pascoli. Moving from an overview of the theme of memory in Pascoli, linked with the motif of phylogenetic memory, the INTRODUCTION, in five chapters, reconstructs the theoretical assumptions and the artistic purposes of Myrmedon, and separates the interpretation of this poem from the exegesis of Pecudes and Canis (all this poems are part of the Ruralia). The most substantial source of Myrmedon is Virgil’s Georgics (4, 1-115; 149-280); this point has been analyzed in the fourth chapter. Finally, the introduction explains the poem’s greek title and the inscription. This section is followed by TESTO E TRADUZIONE, and then by six chapters dedicated to a close reading of the vv. 1-14 (6 PROTASI); 22-32 (7 I CARUSI SICILIANI); 33-40 (8 LA VISTA DELLE FORMICHE); 225-238 (9 SCHIAVE); 261-290, 65-75 and 223-224 (10 ANCORA SUL LESSICO DEL MYRMEDON); 301-312 (11 NOZZE). These chapters contain a specific introduction about the motives and peculiarities of the sections, and a wide commentary on: formal aspects, biographical notice, and psychological, theoretical, intertextual influences of the poem. The final chapter (ASPETTI STILISTICI E FIGURATIVI DEL MYRMEDON) analyzes some fragments of the poem clearly linked to impressionistic tendencies and to the fin de siècle decorativism (Myrm. 61-64 and 97-99). A particular attention has also been given to phonosymbolic phenomena and to the more expressive and frequent hexametric formulas. [edited by Author]

Résumé :

Vänerns stränder håller på att växa igen av buskar, träd och vass, detta hotar den biologiska mångfalden runt sjön Många vikar och sund täcks av vass och detta är en stor orsak till att de hotade arterna får svårt att överleva, möjliga orsaker till igenväxning är ökat kvävenedfall, markdeponerat kväve från jordbruk, minskad skötsel i form av bete eller slåtter samt reglering av vattenståndet i sjön. Många arter kräver en öppen solbelyst miljö för sin överlevnad, så även Liten myrlejonslända (Myrmeleon bore) som kan fungera som en indikator för hög biologisk mångfald. Syftet med denna rapport är att ge en bild av vilka faktorer i naturen som gynnar liten myrlejonslända. Detta för att eventuellt kunna bidra med underlag vid vidare arbete med restaurering av Vänerns stränder och omgivande mark. Liten myrlejonslända föredrar torra väl solexponerade sandslänter i söderläge där den finns en bit upp från strandkanten. Inventeringen av larver av Liten myrlejonslända på stränder gjordes med hjälp av linjetransekter med 2 meters mellanrum, där man räknar fångstgroparna som byggs av myrlejonsländans larver. De miljövariabler som mättes i undersökningen för att kunna se ett eventuellt samband med förekomsten av Liten myrlejonslända var trädtäthet, väderstreck på stranden, avstånd till annan strand med förekomst av Liten myrlejonslända, kornstorlek, lutningen av stranden, andel blottad sand på stranden, andel vegetation på stranden samt förekomst av tall i strandområdet. Analysen visar att den viktigaste förklaringsfaktorn för förekomst av Liten myrlejonslända är närhet till annan strand där det förekommer Liten myrlejonslända. Som förklaringar till variationer i tätheten hos Liten myrlejonslända finns sluttning på stranden främst följt av andelen blottad sand på stranden.
The beaches of Lake Vänern in Sweden are in a stage of being overgrown by bushes, trees and reeds. Today many of the bays and channels are covered with reeds, and this is one of the main reasons for the loss of species around the beaches of Lake Vänern. Causes that may be affecting, for example, increased nitrogen deposition, increased amounts of ground deposited agricultural nitrogen, reduced maintenance in the form of grazing or mowing, and also the fact that the water levels are being regulated in the lake which reduces the natural fluctuations that may otherwise contribute to a more open beach environment. Many species are dependent of an open sunlit area for their survival and amongst them is the small antlion (Myrmeleon bore), who can serve as an indicator species for the biodiversity of an area. The purpose of this report is to provide a frame of what factors in nature that favors small antlion. This is to possibly provide a basis for further work on the restoration of the shores of Lake Vänern and surrounding land. The small antlion prefers dry, well sunlit sand slopes, where it can be found somewhat uphill from the shoreline. The inventory of larvae of small antlion on beaches were made using line transects with 2 meter intervals, from where the conical traps built by the antlions where counted. The environment variables that were measured in the survey in order to see a possible link with the presence of small antlion was tree density, cardinal on the beach, distance to another beach with the presence of small myrlejonslända, grain size, the slope of the beach, proportion exposed sand on the beach, proportion of vegetation on the beach and the presence of pine in the beach area. The analysis shows that the most important explanatory factor for the occurrence of small antlions is proximity to another beach where there are small antlions. As explanations for variations in the density of small antlions, slope of the beach was number one followed by the proportion of bare sand on the beach.

The land arthropod secretory system is formed by structures called Malpighian tubules. These tubules are extremely important in insects because they maintain osmoregulation. They are located in the body cavity. They are either free or inserted in the rectum wall, forming an arrangement known as the cryptonephridial system.

Secondary specializations are found in Malpighian tubules, in which a region of the tube may be involved in the production of some substances, while other regions are responsible for other products. This is what occurs in cases of certain species of the order Neuroptera, which utilize tubules to produce cocoon silk thread during the last larva stage. The cells of Malpighian tubules of Myrmeleon sp undergo endoreduplication during the species' larval development, and they become highly polyplodic in the last larvae stage. However, this increased ploidy does not establish itself in all parts of the tubule, but only in select regions, which suggests that only some parts of the tubule undergo these modifications for silk production while the other regions of the tubule are still used for basic functions of osmoregulation.

Résumé :

Following the first record of Myrmeleon bore (Tjeder, 1941) in the Dresden Heath area in 2019 (KURTH 2020, Sächs. Entomol. Z. 10: 71-80), the population size and density of the species was determined. M. bore mainly was found in open, sparsely vegetated, sandy areas with direct sunlight exposure. The area-weighted density of the entire study site (4.05 hectares) was 0.177 larvae/m2. Population size estimates based on random quadrat counts lead to a figure of 4000-7000 individuals - the largest known population of this species. The positive correlation between larval size and pit diameter known for this species from laboratory trials was confirmed at our study site. This correlation may allow researchers to estimate the age structure of wild populations. Given the special responsibility of Germany for the protection of this species and the size of the population, we urge the protection of the site and a prioritisation over other protected species found in the area.

Résumé :

The minute moth Conopomorpha cramerella is a dainty insect that poses a serious threat to the cacao industry in Southeast Asia – the cocoa pod borer. This insect is responsible for losses to the Indonesian cacao industry of some $500 million annually, and unfortunately, it has been reported from northern Australia. Cacao is also attacked by two lepidopterans (Eulophonotus myrmeleon and Zeuzera coffeae) and a weevil (various Pantorhytes species), which bore through the stem of the tree, causing considerable damage. This chapter examines the life cycles of these cocoa pod borers and cocoa stem borers and looks at how an understanding of their biology and ecology can help to manage these pests.
