Study of the biology and ecology of the Muscidae Family (Insecta: Diptera): Collections

Adults can be predators, hematophagous and detritivores or feed on numerous types of exudates from plants or animals. They can be attracted to various substances including sugars, sweets, tears, and blood. Larvae appear in a variety of habitats, including decaying vegetation or animals, dry or moist soil, insect, or bird nests, fresh or stagnant water, and droppings. The objective of the mini review consists of bibliographical research on the muscoid dipterans of the Family Muscidae. The research was carried out in studies related to quantitative aspects of the Family and Species (taxonomic groups) and in conceptual. A literature search was carried out containing articles published from 1971 to 2021. The mini review was prepared in Goiânia, Goiás, from August to September 2021, through the Online Scientific Library (Scielo), internet, ResearchGate, Academia.edu, Frontiers, Publons, Qeios, Portal of Scientific Journals in Health Sciences, https://goo.gl/gLTTTs and https://www.growkudos.com/register. Although some species are very common worldwide, such as the housefly and the stablefly due to their synanthropy, most species do not have this behavior, so they are restricted to some territorial areas, sometimes-small dimension.

Biology study of white grub Holotrichia nagpurensis (Scarabaeidae: Melolonthinae)

Biology of polyphagous insect pest Holotrichia nagpurensis was studies in laboratory during 2019-2020. H. nagpurensis beetles (all types mated, unmated, male and female) were collected by using Light traps (fitted with 6-8 watts mercury tube Light; ACTINIC BL, PHILIPS) placed nearby host Neem trees, Azadirachta indica, Guava, Psidium guajava, Bakayan, Melia azedarach, in evening time from 7:45 to 9: 45 pm in the moths of June-July from Noorpur village in Ghaziabad district of Uttar Pradesh, India (28.7444° N, 77.5526° E) and identified by National Bureau of Agricultural Insect Resources, Bengaluru, Indian Council of Agricultural Research. All collected beetles kept individually in 1 liter capacity containers with moist soil. The mated female laid eggs an average of 29.800±3.247 eggs singly at a depth of 5-10 cm in the moist soil. The incubation period of the eggs was 12.960±0.501 days. 1st instars lasted 17.660±0.510 days; subsequent 2nd and 3rd instars were lasted for 35.140±0.530 and 86.120±0.800 days, respectively. The pupal period was recorded about 25.860±0.515 days and adult longevity was observed 101.860±3.575 days. Total life cycle recorded 277.960±3.371 days with 59.840±4.676 % survival and 0.518±0.039, 3.548±0.080 and 0.368±0.026 larval growth index, pupal growth index and developmental index respectively. All grubs feed on live maize roots in controlled conditions up to pupation. The simple methodology for rearing of root grubs on live maize roots under laboratory conditions was attempted and life cycle of H. nagpurensis was studied successfully.

Assessing the soil color by traditional method and a smartphone: a comparison

Based on the hypothesis that there is a high agreement between pedologists and a smartphone application in the assessment of soil color; the objective was to compare the perceptions of pedologists and an application in obtaining the color of an Argissolo [Lixisol] (A, E and B horizons). Ten aggregates of each horizon were collected. In a single day, under the same lighting conditions, three pedologists described the color components (hue, value, and chroma) of each aggregate (dry and moist soil) using the Munsell soil color chart. Each one of the ten aggregates, from each horizon, was photographed (dry and moist soil sequence) using the camera of a Motorola Moto G4 Plus smartphone. The distance of the camera to the aggregates was 25 ± 5 cm. Also, each aggregate was placed on a white sheet of A4 size paper (background). The application used was Soil Analysis Pro. The percentage of agreement between pedologists and application was obtained concerning hue, value, and chroma. The data were subjected to analysis of variance, in a completely randomized design, with ten replicates. Action Stat® software was used for statistical analysis. It was concluded that the agreement between pedologists and the smartphone application was medium for hue and chroma and low for value. For the dry soil condition, there is a high agreement between pedologists and the smartphone application, especially in the perception of hue and chroma. Thus, the smartphone application has the potential to be used in routine descriptions of soil color.

Modern views on the diversity and taxonomy of Euglenoids. Current state and challenges for the future in the field of diversity, ecology, and biogeography of photosynthetic euglenoids

Photosynthetic euglenoids represent a large group of flagellates, which could be found in most freshwater, marine and brackish habitats, but also in extreme environments with low pH or in moist soil. The existence of this group has been known for a relatively long led to the description of wide morphological variability. In my contribution, I briefly summarize the possible causes of this morphological variability (effect of the environment and phenotypic plasticity during ontogenesis) and current knowledge about the taxonomy of these protist organisms, showing the most recent changes and descriptions of new genera.

Possibly Invasive New Bioenergy Crop Silphium perfoliatum: Growth and Reproduction Are Promoted in Moist Soil

The cup plant (Silphium perfoliatum) is a new and promising bioenergy crop in Central Europe. Native to North America, its cultivation in Europe has increased in recent years. Cup plant is said to be highly productive, reproductive, and strongly competitive, which could encourage invasiveness. Spontaneous spread has already been documented. Knowledge about habitat requirements is low but necessary, in order to predict sites where it could spontaneously colonize. The present experimental study investigates the growth and reproductive potential of cup plant depending on soil moisture, given as water table distance (WTD). In moist soil conditions, the growth and reproductive potential of cup plant were the highest, with about 3 m plant height, 1.5 kg dry biomass, and about 350 capitula per plant in the second growing season. These parameters decreased significantly in wetter, and especially in drier conditions. The number of shoots per plant and number of fruits per capitulum were independent of WTD. In conclusion, valuable moist ecosystems could be at risk for becoming invaded by cup plant. Hence, fields for cultivating cup plant should be carefully chosen, and distances to such ecosystems should be held. Spontaneous colonization by cup plant must be strictly monitored in order to be able to combat this species where necessary.

Gambaran Infeksi Soil Transmitted Helminth Pada Petani Di Desa Gelgel Kabupaten Klungkung

Soil transmitted helminth (STH) infections is kind of helminth infection which transmitted by contact with warm and moist soil especially affect the farmer. The purpose of this study was to investigate the profile of STH infection and the intensity of STH infection among farmers in Gelgel Village, Klungkung, Bali. The cross sectional study was conducted in Gelgel Village, Klungkung District, Bali and obtained stool and quitionaires from farmers by informed consent. Kato-Katz technique was used to diagnose the STH infection and to determine the intensity of infection based on the number of eggs per gram feces (EPG). Total 162 stool samples were collected from farmers aged 25-80 years, 22 farmers was positive of STH infection and 140 farmers was negative of STH infection. The result showed prevalence of STH infection was 13,5%, single infection of A. lumbricoides was 1.85%, 9.26% of T. trichiura single infection, and 0.61% of Hookworm single infection. The mixed infection was detected that were 1.23% of A. lumbricoides with T. trichiura, and 0.61% of A. lumbricoides with Hookworm. STH infection is the health problem among farmer. The farmer must be admitted antihelminthic drugs for preventing and eleminating STH infection.
