Opis:
Scots pine (Pinus sylvestris L.) is the most spread forest tree species in Polissya and the most damaged by foliage browsing and stem insects. The aim of this study was to reveal the changes in the distribution of different forest site conditions for 2010–2019 in Scots pine forests of the selected forestry enterprises of Polissya and possible consequences for the spread of foliage browsing insects. Database of Production Association ‘Ukrderzhlisproekt’ (by 2010 and 2019) was analysed for five State Forest Enterprises (FE) that are located in the Central (Zhytomyr Region) and Western (Rivne and Volyn Regions) Polissya, where the large scale outbreaks of stem pests were registered last decade. The types of forest site conditions were designated in accordance with the Ukrainian typology. Distribution of the forest area by trophotops and hygrotops was evaluated for the forest-covered area, for Scots pine stands, and for pure Scots pine stands in 2010 and in 2019. For 2010–2019, the area of all Scots pine forests and its proportion in the forest-covered area has significantly decreased in the most of analysed forest enterprises. The change for 2010–2019 in the distribution both by the trophotops and by hygrotops of the entire forest-covered area, the area of all Scots pine forests and pure pine forests is not statistically significant. However, in assessment year 2019, the proportion of stands in the moist types of forest site conditions slightly increased. It may be the result of the stands’ mortality in the driest sites after an outbreak of bark beetles. A greater decrease in the proportion of Scots pine forest area in the dry poor, fresh poor, and dry relatively poor forest site conditions was found in the western direction. Therefore, the noted decrease in the foci areas of foliage browsing insects in Polissya in 2010–2012 compared to the 2000–2002 could be associated with a decrease in the most preferred stands, namely the poorest and driest types of forest site conditions.

Opis:
Developments in bioengineering natural products from insects with potential use in modern medicines as well as in utilisation of insects as models for studying essential mammalian processes such as immune responses to pathogens are discussed in this review. The significant recent advances in developing insect derived natural products as potential new medicinal drugs and the use of medicinal plants for the treatment of human diseases has long been practised since the beginning of human civilization. To date, insects have been relatively neglected as sources of modern drugs although they have provided valuable natural products, including honey and silk, for at least 4-7000 years. The use of insect derived products as an alternative medicinal source is an exciting and rapidly expanding new field since insects are hugely variable and have a high biodiversity index. Insects products, such as silk and honey, have already been utilised commercially for thousands of years and extracts of insects used to produce for use in folk medicine around the world, nowadays several other insect products such as venoms which insects use for prey capture and defences, are also used to produce new medicinal drugs which are capable of fighting against a number of diseases like arthritis, inflammation, several cancers, neurological diseases and AIDS too. In the present decade the increasing price of biochemical medicines for the treatment of certain deadly diseases like cancer, AIDS etc is creating a huge economical burden to the common people in the developing countries like India. The search for alternative cost effective and easily available medicines for combating the upcoming diseases is an utmost need in the present decade. The emergence of this kind of alternative medicinal sources like that from the adult insects as well as from their different life history stages or their secretions which are available in plenty in the nature will open up new vistas in the recent researches based on development of medicinal drugs for human diseases.

Obecnie wymieranie owadów zapylających staje się problemem ogólnoświatowym. Jest to istotne nie tylko z punktu widzenie utraty bioróżnorodności, ale ma ogromne znaczenie dla rolnictwa i gospodarki żywnościowej świata. Tradycyjne sposoby ochrony owadów i innych zapylaczy postrzega się, albo w kategoriach ochrony gatunkowej, albo ochrony biotopowej, w ich naturalnych lub półnaturalnych siedliskach. Jednak coraz czyściej podejmuje się próby ochrony tej grupy owadów w środowiskach silnie zmienionych przez człowieka, jak na przykład aglomeracje miejskie i towarzysząca im infrastruktura. Istnieją też inne propozycje, jak na przykład zakładanie pewnego rodzaju upraw - „Ostoje Zapylaczy”, na niewielkich poletkach w sąsiedztwie pól uprawnych lub miejscach nie przydatnych gospodarczo. W obecnej sytuacji wszystkie propozycje ochrony, zarówno te starsze - klasyczne, jak i te nowe, powinny być stosowane w sposób kompleksowy, bo tylko to może przynieść poprawę sytuacji owadów zapylających.

Opis:
Monitoring systems should be simple, time and cost effective, and collect as much information as possible, regarding the diversity of the communities under study. Most of studies use ultraviolet light traps to survey moths, although is known that the spectral sensitivity of moths has other wavelengths absorption peaks. As wider is the spectrum emitted by the lamps the wider is the fauna attracted and possible to be collected. The wider spectrum of actinic light, once it emits a large part of the ultraviolet wavelength as well as a peak at the blue, attracted more species than the ultraviolet light. In 2018 and 2019 the actinic light captured more species in 75% of the surveyed areas, while in 2020 in all areas. In 2018 and 2019, the power of the actinic light was 15 W and the ultraviolet light only 8 W. The actinic light trap captured, in 295 samples (50%), more species than the UV light trap which had a better performance in 201 samples (34%). In 2020 both light traps have the same power, 8 W, and results were similar, the actinic light collected more species in 123 samples (50%) than the ultraviolet light which in 48 samples (35%) collected more species than the actinic light.

Opis:
Red-headed crickets were kept in glass insectariums equipped with drinkers, food containers and peat boxes for laying eggs. In the first stage of the experiment, the insects were divided into three groups, kept at 20°C, 25°C and 29°C, respectively. Three days after placing the crickets in the insectariums, the eggs were counted. In the second stage, the eggs (15 pcs.) were placed in boxes with peat in insectariums and exposed to the same temperatures as the females were kept at 20°C, 25°C and 29°C respectively, and the time in which the larvae hatch in each container was observed. It was found that the thermal conditions of the environment influence the number of eggs laid by female Gryllus assimilis and the length of the embryonic period in red-headed crickets. It is estimated that in the temperature range of 20–29°C, increasing the temperature by 1°C shortens the time needed to hatch the larvae from the eggs by 2 days.

Opis:
The paper presents an application of signal processing and computational intelligence methods to detect presence of the wood boring insects larvae in the wooden constructions (such as the furniture of buildings). Such insects are one of the main sources of the degradation in such objects, therefore they should be detected as quickly as possible, before inflicting serious damage. The presented work involved the acoustic monitoring for detecting the presence of the larvae inside pieces of wood. An accelerometer was used to record the sound, further analyzed by a computer algorithm extracting features important for artificial-intelligence (AI) based classification employed to detect the old house borer’s (Hylotrupes bajulus L.) activity. The presented task is difficult, as the sounds made by the larvae are of relatively low amplitude and the background noise caused by people, electrical appliances or other sources may significantly degrade the accuracy of detection. The classification of sounds is needed to separate sources of noise which deteriorate the proper larva detection and should be suppressed if possible. The employed classification was based on features defined in the time domain followed by the support vector machine used as the binary classifier. The results allowed us to assess the effectiveness of the old house borer’s detection by the acoustic analysis enhanced with the AI algorithm.

Opis:
The Upper Cretaceous Capacete Formation, from the intracratonic Sanfranciscana Basin, central Brazil, consists of epiclastic sediments with a significant aeolian contribution. This unit has been traditionally interpreted as deposited by alluvial fans distally grading to braided rivers in an arid- to semiarid climate within the central part of southwestern Gondwana. Locally, some expositions with wide lateral extension show architectural elements indicative of deposition in meandering rivers, such as floodplain fines (FF) interbedded with crevasse splay (CR), lateral-accretion macroforms (LA), and channels (CH). Bioturbation within the meandering fluvial deposits is commonly associated with the floodplain element, mainly occurring in fine-grained sandstone and mudstone. The lateral-accretion elements and channel deposits are barren of trace fossils. Sandstone with climbing ripples (Sr) from the element CR show low bioturbation of meniscate trace fossils assigned to Taenidium, Beaconites, and Scoyenia ichnogenera. Simple vertical and horizontal burrows identified as Skolithos and Palaeophycus occur associated with Taenidium and Camborygma in sandstone facies (Sr, St and Sh), as well as rhizoliths, representing the Scoyenia ichnofacies. The predominance of trace fossils related to the FF and CR architectural elements attests to the colonization mostly by insects in episodic and vegetated flood plains of the meandering river system from the Capacete Formation. Thus, despite the primarily arid to semiarid conditions interpreted for the inner parts of the newly formed South American continent during the Upper Cretaceous, our new data support deposition under humid conditions in some intervals of the Capacete Formation from the Sanfranciscana Basin.

Opis:
Fleas are highly specialized holometabolic insects. So far, only 16 species of fossil fleas in five families have been reported due to the rare fossil records. At present, the earliest flea fossils are reported from the Middle Jurassic Jiulongshan Formation of Northeastern China. The descriptions of these earliest species pushed back the origin of Siphonaptera by at least 40 million years. It is generally accepted that saurophthirids are the “transitional” taxa from stem Jurassic fleas to living crown groups. Herein, we described a new “transitional” flea species, Saurophthirus laevigatus Zhang, Shih, Rasnitsyn, and Gao sp. nov., from the Lower Cretaceous Yixian Formation of Northeastern China, assigned to Saurophthiridae. The new species provides new evidence to support saurophthirids as a “transitional” group. Sexual dimorphism suggests significant differences in biology of opposite sexes in Saurophthirus. Analysis of described Mesozoic species demonstrates the body size reduction from the Middle Jurassic to the Early Cretaceous. Smaller body size was likely advantageous in reducing the probability of being detected and removed by the host and in minimizing flea’s demand for blood intake and energy input, indicating the adaptation of the ectoparasitic lifestyle of fleas in their early stage of evolution.

Opis:
The insecticidal efficiency of Ag-loaded 4A-zeolite (ZAg) and its formulations with Rosmarinus officinalis essential oil (RO) was evaluated against Sitophilus oryzae (L.) and Rhyzopertha dominica (F.). For comparison, different rates of ZAg (0.25, 0.5, 0.75, and 1 g kg–1 wheat) were used solely and in a combination with LC50 concentrations of RO. Mortality was assessed after 7, 14, and 21 days of insect exposure to treated wheat. The progeny production was also evaluated. The use of ZAg accomplished a complete mortality (100%) on S. oryzae and 96.67% on R. dominica as well as 100% mortality of progeny against the two insect species after the longest exposing duration (21 days), at the highest rate (1 g ⋅ kg–1). On the other hand, the complete mortalities of ZAg formulations on S. oryzae were obtained after 14 d of treatment with F1 formulation (0.605 g ⋅ kg–1 RO + 0.25 g ⋅ kg–1 ZAg) and after 7 days with the other tested formulations. In addition, the complete mortality on R. dominica was obtained only by F8 (0.059 g kg–1 RO + 1 g kg–1 ZAg) formulation after 14 days of treatment. Concerning the efficiency of the examined formulations on the progeny of S. oryzae, F1 (0.605 g ⋅ kg–1 RO + 0.25 g ⋅ kg–1 ZAg) and F2 (0.605 g ⋅ kg–1 RO + 0.5 g ⋅ kg–1 ZAg) formulations recorded 100% mortality. In addition, F3 (0.605 g ⋅ kg–1 RO + 0.75 g ⋅ kg–1 ZAg) and F4 (0.605 g ⋅ kg–1 RO + 1 g ⋅ kg–1 ZAg) formulations suppressed the progeny production. Furthermore, the complete mortality of R. dominica progeny was obtained with F7 (0.059 g ⋅ kg–1 RO + 0.75 g ⋅ kg–1 ZAg) and F8 (0.059 g ⋅ kg–1 RO + 1 g ⋅ kg–1 ZAg) formulations. ZAg, especially its formulations with R. officinalis oil, had potential effects against two stored-product insects. F1 and F8 formulations could be treated efficiently on S. oryzae and R. dominica, respectively.

Opis:
In terms of flowering ecology, Pulsatilla flowers are classified as “pollen flowers” producing inconsiderable amounts of nectar. The aim of this study was to assess the length of the flowering period in Pulsatilla slavica and P. vulgaris and to investigate the structure of the epidermis of the perianth and generative elements of their flowers. Special focus was placed on the structure of hairs and the distribution of stomata. The weight of nectar released by the flowers of the two Pulsatilla species and the content of sugars in the nectar was also evaluated. In SE Poland, both species flowered for similar periods between the second half of April and the first half of May. The flower life-span of both was determined to be 9–14 days. The lower part of each sepal was observed to be covered by long hairs having cellulose-pectin cell walls of varying thickness. Hairs present on the pistil style are thinner; they may provide some protection against cold and can play a role of a secondary pollen presenter for insects. The bowl-shaped structure of the perianth and the nature of the adaxial surface of the sepal epidermis may facilitate reflection of sunlight into the inner parts of the flower, which may contribute to an elevation of the intraflower temperature. This is particularly important for the functionality of the ovary. The surface of the hairs was seen to be covered by a cuticle ensuring water impermeability. Flowers are visited by honeybees, bumblebees, butterflies, and ants, for which nectar and pollen are the main attractants. Ants, which are regarded as illegitimate flower visitors, were found to cause damage to the androecium. The number of fruits produced in the flowers of both Pulsatilla species was lower than 50% of the number of pistils.
Z punktu widzenia ekologii kwitnienia kwiaty Pulsatilla zaliczane są do kwiatów pyłkowych, które wytwarzają niewielkie ilości nektaru. Celem badań było określenie długości kwitnienia Pulsatilla slavica i Pulsatilla vulgaris oraz analiza budowy okwiatu i elementów generatywnych w aspekcie ekologii zapylania. Szczególną uwagę zwróciliśmy na budowę włosków i występowanie aparatów szparkowych. Określiliśmy również masę nektaru wydzielanego przez kwiaty dwu gatunków Pulsatilla oraz zawartość cukrów w nektarze. Badane gatunki kwitną w zbliżonych terminach od drugiej dekady kwietnia do pierwszej dekady maja. Długość życia ich kwiatów wynosi 9–14 dni. Występujące na dolnej powierzchni listków okwiatu długie włoski mają celulozowo-pektynowe ściany komórkowe o zróżnicowanej grubości. Włoski zlokalizowane na szyjce słupka są cieńsze i służą prawdopodobnie jako ochrona przed chłodem oraz mogą stanowić wtórny prezenter pyłkowy. Miseczkowaty kształt okwiatu i budowa powierzchni doosiowej epidermy listków okwiatu mogą umożliwiać odbicie promieni słonecznych do środkowej części kwiatu i skutkować podwyższeniem temperatury w jego wnętrzu. Jest to szczególnie ważne dla funkcjonowania zalążni. Powierzchnię włosków pokrywa kutykula, co czyni je nieprzepuszczalnymi dla wody. Kwiaty odwiedzane są przez pszczołę miodną, trzmiele, motyle i mrówki, dla których istotnym atraktantem jest nektar i pyłek. Mrówki zaliczane do nieuprawnionych owadów odwiedzających kwiaty powodowały uszkodzenia pręcikowia. Stwierdziliśmy, że liczba powstających owoców w kwiatach dwóch gatunków Pulsatilla wynosi mniej niż 50% w stosunku do liczby słupków w kwiecie.

Opis:
The aim of this study was to evaluate the possibility of using insect flour for sponge cake supplementation. Consumer acceptance, chemical composition, textural properties, and microbiological characteristics were determined. The addition of mealworm flour significantly increased the content of nutrients, especially protein, ash, lipid, and dietary fiber. Mealworm flour influenced the color parameters as well as textural properties. The fatty acid profile was dominated by monounsaturated fatty acids, ranging from 9.72 g/100 g for wheat flour sponge cake to 41.82 g/100 g for sponge cake with 20% addition of mealworm flour. The amino acid profile of mealworm flour was characterized by a significantly higher content of essential amino acids compared to wheat flour and sponge cakes. Sponge cake supplementation resulted in a good nutritional value of protein except for lysine which was the limiting amino acid in all samples. However, the limiting amino acid index was 63.04-63.10% compared to 30.38% for the mealworm and wheat sponge cake, respectively. The presence of insect flour reduced the organoleptic properties of the obtained sponge cakes, regardless of its quantity. The addition of mealworm flour contributed to a significant reduction in the hardness and fracturability of the sponge cakes on the baking day and during the 30-day storage. Insect flour addition did not reduce the microbiological safety of the final product. The study results indicate the possibility of using mealworm flour in the production of confectionery products.

Opis:
Scientists around the world are interested in edible insects as a source of valuable nutrients. Among the most often described are crickets, which represent a source of significant amounts of protein, lipids, vitamins, and minerals. This article reports results of a study into the effect of starch-to-cricket powder (CP) addition on the free amino acid profile as well as potential odorants in gluten-free (GF) bread. A significant 2.6-fold increase was observed in the content of essential amino acids in the CP-enriched GF bread. Moreover, the CP addition resulted in the formation of many volatile compounds, such as pyrazines, furans, and sulfur-containing compounds, which exhibit strong aroma-enhancing properties. The attractiveness of the CP-enriched bread was confirmed by the results of the sensory analysis, showing a significant improvement in its flavor when compared to the traditional GF bread without CP. GF bread enriched with CP was characterized by caramel, roasty, and cooked potatoes notes. On the basis of the obtained results, it was concluded that the use of CP not only improves the nutritional value but also aroma of GF bread.

Opis:
Celem niniejszego artykułu jest próba nakreślenia sposobów, za pomocą których Samuel Beckett wiąże śmierć z figurami owadów, stanowiącymi jeden z najbardziej dopracowanych i konsekwentnych tropów zwierzęcych w jego literackim uniwersum. Jak się okazuje, w przeładowanych antropocentryzmem dziełach irlandzkiego pisarza zwierzęta zaskakują czytelnika tym, jak wiele z ich gatunków oraz okazów zamieszkuje jałowe i martwe przestrzenie Becketta. Owady nie stanowią w tej kwestii wyjątku: w światach Becketta spotykamy muchy, pszczoły, szerszenie, osy czy mrówki. Wychodząc od antropocentrycznego odczytania dzieł autora Końcówki przez Alaina Badiou, autor przesiewa tę interpretację przez maszynę antropologiczną Giorgio Agambena oraz posthumanistyczne rozważania Rosi Braidotti. W odróżnieniu od figur ludzkich, które skazane są na niekończącą się agonię pozbawioną wieńczącego ją wydarzenia, owady zostają odczytane jako byty przynależące w pełni do śmierci, sporadycznie przebijające się poprzez jej mur do świata żywych. Podążając za tym rozpoznaniem, autor stara się ukazać powyższą tezę na kilku różnych planach. W artykule zostaje zinterpretowana rola Worma (dosłownie: Robaka) w Nienazywalnym, a także jego niejasny status ontologiczny. W Molloyu zanalizowana zostaje relacja Morana do jego pszczół: obserwacja ich tańca oraz odkrycie ich śmierci oraz zwłok. W końcu, w dalszych częściach artykułu odczytana zostaje fascynująca Becketta logika roju, a także metonimiczne związki owadów z technologią, których tanatyczne aspekty ujawniają intrygujące związki ludzi i nieludzi w dziełach autora Końcówki.
In the broadest possible terms, this paper aims at exploring the relation between death and insects in Samuel Beckett with a special emphasis put on the fact that it is insects that form one of the most repetitive and complex animal figures in his oeuvre. Surprisingly, his otherwise desolate and bleak spaces – despite the inherent anthropocentric framework they are founded on – are inhabited by the plethora of nonhuman species. Insects are here no exception; Beckett’s writings are abundant in references to flies, bees, hornets, wasps, or ants. The paper begins with confronting Alain Badiou’s take on Beckett with Rosi Braidotti’s and Giorgio Agamben’s theories, including the anthropological machine. It is argued that, contrary to the human figures condemned to ceaseless agony and torment deprived of the ultimate horizon of death, insects belong entirely to the realm of death in Beckett; in other words, they struggle to breach through the wall of life. In order to prove that, I discuss the unclear ontological status of Worm in The Unnamable. Moreover, the paper reconstructs Moran’s relation to his bees, depicted in Molloy, including his insightful study of the waggle dance and the discovery of their cadavers. Finally, the paper focuses on the logic of a swarm, which Beckett seems to be fascinated with, and the metonymies of insect tropes and technology, whose Thanatic aspects disclose the unsettling connections between humans and nonhumans in Beckett’s works.
