The family Chrysopidae has several genera of which the genus Chrysoperla is more important of them. These lacewings are beneficial insects when they have high potential for predation on harmful aphids which can be used in their biological control programs. Due to high importance of these lacewings in Ardabil province in northwest zone of Iran, identification of their species was done. By examining the collected specimens with morphological features, wing venation, male reproductive organ, and claws shape (as the best way to identify the species) fi nally 4 species were identified including Chrysoperla carnea (Stephens), Chrysoperla kolthoffi Navas, Chrysoperla lucasina Lacroix, and Chrysoperla sillemi Esben-Petresen.

The cytological features including chromosome numbers and detailed chromosome measurements of 46 populations of ten Achillea species (A. aleppica, A. bibersteinii, A. eriophora, A. filipendula, A. millefolium, A. nobilis, A. pachycephala, A. tenuifolia, A. vermicularis, and A. wilhelmsii) were reported from Iran. Sample plants and seeds were collected from diff erent geographical regions of Iran. Total chromosome length, long/ short arm ratio, centromere index, total form percentage, inter and intra-chromosomal index, different relative lengths of the mitotic chromosomes were calculated. The populations showed one basic chromosome number x = 9 with two ploidy levels (2x and 4x). The chromosome numbers of A. filipendula, A. nobilis and A. pachycephala, for the first time are new to science and new ploidy levels are reported for A. biebersteinii (4x) and A. wilhelmsii (2x). The mean of chromosome length ranged from 3.8 μm in A. millefolium from Semnan, Chasham, Sirat to 6.37 μm in A. nobilis from Golestan, Agh Emam. Karyotype analysis indicated that chromosomes of Achillea taxa have predominantly median and sub-median centromeres. Several karyological aspects of these taxa are discussed in the light of the cytogenetic data.

Microplastics (MPs) – consisting of small plastic particles with size less than 5 mm – have become ubiquitous environmental contaminants. Even though plastics are mass produced and proved to be useful in many applications, they may have potentially negative impacts on environment and human health. Multiple sizes, shapes, and polymer types, and their various sources can influence the environmental and human health effects of MPs. Being present in oceans, freshwater, soils and air, MPs can cause human exposure via ingestion, inhalation, and dermal contact, resulting possibly in oxidative stress, inflammation, altered balance in metabolism and immune system, neurotoxicity, reproductive toxicity, and cancer risk. Also, MPs can act as vectors of toxicants or microorganisms. All the same, public awareness towards MPs is currently low, and a lot of studies related to MPs are still ongoing. Further research is needed for a better understanding of MPs’ occurrence in environmental systems and their human health effects.

Saffron cultivation is a viable alternative for marginal areas where low soil fertility and water availability severely limit the cultivation of other crops with higher water and input requirments. Under these conditions, arbuscular mycorrhizal fungi (AMF) are an essential alternative for maintaining fertility and water conservation, stimulating growth, and providing plant protection against soil-borne diseases. The aim of this work is to highlight the diversity of the arbuscular mycorrhizal fungi communities associated with saffron roots in plantations of different ages (two, four and ten years old) in the region of Taliouine (Morocco). The highest number of endomycorrhizal spores was recorded in the rhizosphere of saffron plants harvested at the level of plots that have carried saffron for two years (138.66/100 g soil), while the lowest number was observed in the rhizosphere of plants of plots that are occupied for 10 years by saffron. All collected spores from plots under study represent 17 morphotypes belonging to 5 genera: Glomus (7 species), Acaulospora (7 species), Rhizophagus (one species), Densicitata (one species), and Funneliformis (one species).

At present very few walnut cultivars can be said to be cosmopolitan cultivars, grown widely in the walnut-producing countries of the world. Walnut (Juglans regia L.) has poor ecological adaptability, as its cultivation is greatly influenced by low temperatures during the winter dormancy period and in early spring. The breeding activities conducted in various countries are therefore of great significance. Choosing suitable locations for cultivation is of key importance if optimum yield stability is to be achieved. The introduction of foreign walnut cultivars regularly runs into problems if, despite their high yielding ability, they are unable to adapt to the Hungarian climate. In Hungary the most critical weather events for walnuts are the frequent frosts in early spring. Buds therefore need to burst late to avoid damage to the flowers. Many papers have dealt with the frost tolerance of stone fruit, but only limited information has been published on the frost tolerance of walnut. For the first time in Hungary, artificial freezing tests were performed in the present work to determine the frost tolerance of the cultivars available in Hungary. The results could be of service to Hungarian growers in choosing the most suitable cultivar.

Extracellular polymeric substances (EPS) produced by laboratory strains Bacillus cereus and Pseudomonas aeruginosa were extracted from cultures incubated at various incubation periods (24, 48, 72, 96 and 120 h). At each sampling time, the EPS were analysed for yield, quality, functional groups present, and their efficacies in copper (Cu(II)) biosorption (using 30 and 50 ppm EPS). Results revealed that EPS yield was influenced by incubation period, with 48-h culture of B. cereus and 96-h culture of P. aeruginosa producing the highest yield of EPS at 8.30 mg and 6.95 mg, respectively. The EPS produced at various incubation periods have similar characteristics in solubility, quality and major functional groups (C-O, CH3, C=C, O-H) present. Efficacy of Cu(II) biosorption was influenced by the amount of EPS used and the EPS-metal incubation time. Although Cu(II) removal was higher for EPS from 24-h B. cereus (18.96%) and 48-h P. aeruginosa (19.19%) when 30 ppm was used, application of 50 ppm EPS demonstrated no distinct differences in amount of Cu(II) removed. This suggested that higher biomass of EPS used and longer EPS-metal incubation period, superseded the efficacy of EPS from various incubation periods.

Mushrooms are macroscopic fruit bodies of fungi; one of the most diverse groups of living organisms distributed all over the world. In recent past, they have gained significant scientific attention for their profound nutraceutical potentiality. The objective of the present study was to explore the diversity and ecological distribution of mushrooms in different forest areas of Bankura district. The study area includes intermittent dense forest and flood plains from middle-east to eastern part of Bankura district. However, this area received very little attention from a conservation perspective, and there is no such documentation on mushrooms of this area. The survey was conducted from August 2019 to October 2020 including vivid field surveys in the forest depots. The study has revealed a total of 53 identified mushroom species belonging to 40 genera and 30 families. The study has also identified 25 edible, 18 inedible and 15 medicinally potential mushrooms. The genus Russula and the family Russulaceae dominates the myco-population. The finding shows that this region is rich in macrofungal diversity complicatedly linked to the functioning of the local ecosystem. The present study opens new possibilities regarding the exploration and utilization of wild mushrooms in India.

Sixteen rice genotypes were screened against combined salinity and submergence stresses to find out potential salt-submergence tolerant genotypes. Rice seedlings were subjected to submergence stress including two salinity levels viz., EC-6 dSm-1 and EC-8 dSm-1 for 10 days. Imposition of combined stress considerably decreased the growth parameters in rice seedlings, however ACM-18, ACM-35, and RC-251 demonstrated the maximum value for growth attributes such as leaf live (%), root and shoot length, plant fresh and dry biomass. The results of correlation and regression revealed a significant and negative association of leaf lives (%), root length, fresh weight of root and shoot, and root dry weight with mean tolerance score under combined stress indicating their importance as the useful descriptors for the selection. Euclidean clustering was categorized the rice genotypes into three major clusters, i.e., A-susceptible, B-tolerant and moderately tolerant, and C-highly tolerant. Results of cluster analysis showed that the highly tolerant genotypes namely ACM-18, ACM-35, and RC-251 were placed in the same cluster. Similar results were further confirmed by principal component analysis having the highly tolerant genotypes in the same group. Combining the morphological and multivariate analysis, ACM-18, ACM-35, and RC-251 were selected as promising genotypes for developing high-yielding salt-submergence tolerant rice.

Salvia officinalis L. and Glycyrrhiza glabra L. are two valuable medicinal plants from Kermanshah province in Iran. In this study, chemical analyses of their essential oils were performed by gas chromatography-mass spectrometry and the effects investigated on functional response of Habrobracon hebetor Say on larval stage of Sitotroga cerealella Olivier. Accordingly, emerged females of H. hebetor were treated by LC30 of the isolated essential oils for 24 h. Then, six wasps were accidentally selected and introduced to densities of host larvae for 24 h. The results showed that naphthalene, decahydro-4a-methyl and alpha-thujone were dominant compounds in both essential oils, respectively. Holling model (1959) by using regression analyses confirmed functional response type III in the control wasps and type II in both essential oils treatments. The highest and lowest attack rates were observed in the control wasps (0.0443 ± 0.00278 h-1) and S. officinalis treatment (0.0349 ± 0.00257 h-1), respectively. Moreover, the treated wasps by G. glabra essential oil showed shorter handling time than S. officinalis treatment (0.4497 ± 0.0373 h versus 0.5196 ± 0.0589 h). Accordingly, G. glabra due to lower negative effects on the functional response of H. hebetor was more compatible than S. officinalis for their combination in integrated pest management schedules.

In this study, chemical analyses of their essential oils were performed by gas chromatography-mass spectrometry and the effects investigated on functional response of Habrobracon hebetor Say on larval stage of Sitotroga cerealella Olivier. Accordingly, emerged females of H. hebetor were treated by LC30 of the isolated essential oils for 24 h. Then, six wasps were accidentally selected and introduced to densities of host larvae for 24 h. The results showed that naphthalene, decahydro-4a-methyl and alpha-thujone were dominant compounds in both essential oils, respectively. Holling model (1959) by using regression analyses confirmed functional response type III in the control wasps and type II in both essential oils treatments. The highest and lowest attack rates were observed in the control wasps (0.0443 ± 0.00278 h-1) and S. officinalis treatment (0.0349 ± 0.00257 h-1), respectively. Moreover, the treated wasps by G. glabra essential oil showed shorter handling time than S. officinalis treatment (0.4497 ± 0.0373 h versus 0.5196 ± 0.0589 h). Accordingly, G. glabra due to lower negative effects on the functional response of H. hebetor was more compatible than S. officinalis for their combination in integrated pest management schedules.","PeriodicalId":34918,"journal":{"name":"Acta Biologica Szegediensis","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45361147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
