    The family Drosophilidae includes over 3750 species worldwide and over 2000 of these are species of Drosophila. Spotted wing drosophila (SWD), Drosophila suzukii is one of the most dangerous species in this family. The insects live on undamaged ripening fruits, using its peculiar serrated ovipositor to break the skin of fresh ripening fruits and lay eggs in it. Drosophila species are very difficult and practically impossible to detect at larval stages. The present investigation was conducted at the All-Russian Plant Quarantine Center and Agrarian and Technological Institute of RUDN University, Moscow, Russia in 2018-2020. The aim of this study was to investigate the method of accurate and rapid identification of D. suzukii, and to design specific primer pairs for pest identification by Real-Time PCR method. The real-time quantitative PCR is a fast, sensitive, repeatable and accurate method for quantifying gene transcript levels. In this study, we designed specific primers (4.Dsuz.FRP) for Real-Time PCR to identify D. suzukii from other relative species. Although D. suzukii is absent in the Russian Federation and has not been reported so far, the project could be a precautionary measure.БСмСйство Drosophilidae насчитываСт Π±ΠΎΠ»Π΅Π΅ 3750 Π²ΠΈΠ΄ΠΎΠ² ΠΏΠΎ всСму ΠΌΠΈΡ€Ρƒ, ΠΈΠ· Π½ΠΈΡ… ΠΊ Ρ€ΠΎΠ΄Ρƒ Drosophila относится Π±ΠΎΠ»Π΅Π΅ 2000 Π²ΠΈΠ΄ΠΎΠ², ΠΏΡ€ΠΈΡ‡Π΅ΠΌ, Drosophila suzukii считаСтся ΠΎΠ΄Π½ΠΈΠΌ ΠΈΠ· самых опасных прСдставитСлСй этого сСмСйства.

    Developing an accurate empirical correlation for predicting anti-cancer drugs’ dissolution in supercritical carbon dioxide

    This study introduces a universal correlation based on the modified version of the Arrhenius equation to estimate the solubility of anti-cancer drugs in supercritical carbon dioxide (CO2). A combination of an Arrhenius-shape term and a departure function was proposed to estimate the solubility of anti-cancer drugs in supercritical CO2. This modified Arrhenius correlation predicts the solubility of anti-cancer drugs in supercritical CO2 from pressure, temperature, and carbon dioxide density. The pre-exponential of the Arrhenius linearly relates to the temperature and carbon dioxide density, and its exponential term is an inverse function of pressure. Moreover, the departure function linearly correlates with the natural logarithm of the ratio of carbon dioxide density to the temperature. The reliability of the proposed correlation is validated using all literature data for solubility of anti-cancer drugs in supercritical CO2. Furthermore, the predictive performance of the modified Arrhenius correlation is compared with ten available empirical correlations in the literature. Our developed correlation presents the absolute average relative deviation (AARD) of 9.54% for predicting 316 experimental measurements. On the other hand, the most accurate correlation in the literature presents the AARD = 14.90% over the same database. Indeed, 56.2% accuracy improvement in the solubility prediction of the anti-cancer drugs in supercritical CO2 is the primary outcome of the current study

    D. suzukii is one of the most dangerous quarantine insects in the world. In this research, some of the important biological and reproductive characteristics of this fly including the average daily egg in two selective and non-selective tests, the length of larval and pupal periods, the percentage of hatching eggs, the percentage of total insect excretion and sex ratio on six different plant hosts persimmons, Clementine mandarin, Valencia oranges, Golden apple smoothie, Red apples, and pears (Mashhad) were measured in laboratory conditions. Among the studied hosts, pear contributed to the highest average egg density of 4.74 eggs per individual fly/day and a hatching percentage of (62.79%). Moreover, it exhibited a short duration of larval stages (4. 10 days) and pupation (7.76 days), the most favorable host for Drosophila suzukii was determined. In contrast, Valencia oranges were identified as the most undesirable host because of the low average egg density and egg hatching percentage (zero and 67.49%), respectively. Due to the high sensitivity of pear fruits to this pest, it is recommended to exercise prudence in the construction of new pear orchards, especially mixed with citrus

    The invasive pest Drosophila simulans is a dangerous insect for territory of Russian Federation and many countries.A large proportion of suspected Drosophilade in transit or discovered in orchard surveys are in the larval stages, as their feeding leads to observable damage to the produce (13). A real-time PCR protocol was set up using two D. simulans positive control samples(from different DNA and region) as well as several non-target species samples as negative controls (Table 2). The designed primer pairs that amplify D. simulans were used in a real-time PCR run on a CFX96 Touch Real-time platform (BioRad, Hercules, CA, USA). Optimization gradients of temperature (55-65Β°C). We developed and validated a rapid, highly sensitive and specific assay based on Real-time PCR. Based on DNA sequence polymorphisms, the findings of the Real-time PCR have shown that this pair of primers (5. ds) classify the exact region of the gene as well as the specific Drosophila simulans primer. The real-time method is a fastand accurate way to identify the molecular nature of a Drosophila simulans; and given that no primer has yet been developed that accurately identifies the Drosophila simulans, this primer can be very useful for researchers. We suggest using this guide in the Russian Federation and other countries in quarantine and in the other academic institutes.Π˜Π½Π²Π°Π·ΠΈΠΎΠ½Π½Ρ‹ΠΉ Π²Ρ€Π΅Π΄ΠΈΡ‚Π΅Π»ΡŒ Drosophila simulans-опасноС насСкомоС для Ρ‚Π΅Ρ€Ρ€ΠΈΡ‚ΠΎΡ€ΠΈΠΈ Российской Π€Π΅Π΄Π΅Ρ€Π°Ρ†ΠΈΠΈ ΠΈ ΠΌΠ½ΠΎΠ³ΠΈΡ… стран.

    D. melanogaster is one of the most harmful citrus fruit flies having a large number of host plants. The molecular diagnostic method has been created for identification the D. melanogaster from another non-quarantine species Drosophila spp. The proposed method for differentiation is to use the mitochondrial DNA cytochrome oxidase I gene region 709-bp. We amplified samples of DNA with primers Droso-S391 and Droso-A381 by D. melanogaster, D. suzukii, and D. Simulans collections in the laboratory samples from many countries and contrasted with sequences of other GenBank Drosophila taxa. The findings of a polymerase chain reaction (PCR) based on DNA sequence polymorphisms showed that these primers accurately identify the area of the gene as well as the unique primers of Drosophila melanogaster.D. melanogaster - ΠΎΠ΄Π½Π° ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ врСдоносных ΠΏΠ»ΠΎΠ΄ΠΎΠ²Ρ‹Ρ… ΠΌΡƒΡ…, ΠΏΠΎΠ²Ρ€Π΅ΠΆΠ΄Π°ΡŽΡ‰ΠΈΡ… цитрусовыС ΠΈ ΠΌΠ½ΠΎΠ³ΠΈΠ΅ Π΄Ρ€ΡƒΠ³ΠΈΠ΅ ΡΠ΅Π»ΡŒΡΠΊΠΎΡ…ΠΎΠ·ΡΠΉΡΡ‚Π²Π΅Π½Π½Ρ‹Π΅ растСния.

    Potato ( Solanum tuberosum L.) is one of the most vital food and industrial crop and Ditylenchus destructor is an influential pathogenic potato nematode and is quarantine pest in many states and territories. As a result, the polymerase chain reaction (PCR) protocol was optimized to identify Ditylenchus destructor reliably and rapidly. The species-specific internal transcribed spacer (ITS) was used as the primer of the D. destructor ribosomal DNA gene. Some populations of this species from the Moscow region in the Russian Federation were investigated through species-specific primer PCR. New sequence from ITS-rRNA was deposited in the GenBank under accession number MN122076. The current molecular technique is more appropriate to distinguishing of nematode species, since it is practical, fast and precise.ΠšΠ°Ρ€Ρ‚ΠΎΡ„Π΅Π»ΡŒ Solanum tuberosum L. - ΠΎΠ΄Π½Π° ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ Π²Π°ΠΆΠ½Ρ‹Ρ… ΠΏΡ€ΠΎΠ΄ΠΎΠ²ΠΎΠ»ΡŒΡΡ‚Π²Π΅Π½Π½Ρ‹Ρ… ΠΈ тСхничСских ΠΊΡƒΠ»ΡŒΡ‚ΡƒΡ€, Π° Ditylenchus destructor являСтся ΠΏΠ°Ρ‚ΠΎΠ³Π΅Π½Π½ΠΎΠΉ Π½Π΅ΠΌΠ°Ρ‚ΠΎΠ΄ΠΎΠΉ картофСля ΠΈ числится Π² качСствС ΠΊΠ°Ρ€Π°Π½Ρ‚ΠΈΠ½Π½ΠΎΠ³ΠΎ Π²Ρ€Π΅Π΄Π½ΠΎΠ³ΠΎ ΠΎΡ€Π³Π°Π½ΠΈΠ·ΠΌΠ° Π²ΠΎ ΠΌΠ½ΠΎΠ³ΠΈΡ… странах ΠΈ Ρ€Π΅Π³ΠΈΠΎΠ½Π°Ρ….

    Zea mays variety 704 (single cross) was studied to investigate effect of chemical fertilizers and growth-promoting bacteria on yield and yield components of corn ( Zea mays ). A factorial experiment was conducted in a completely randomized block design with three replications at Tehran-Varamin Research Farm (Iran) in 2017. The treatments were as follows: inoculation of the seeds with growth promoters in four levels: Rhizobium , Azospirillum , Azotobacter and Pseudomonas ; Rhizobium , Azospirillum and Pseudomonas ; Rhizobium , Azotobacter and Pseudomonas ; Azospirillum , Azotobacter and Pseudomonas and use of nitrogen (N) and phosphorus (P) fertilizers at four levels: no use, 1/3, 2/3, and 100 % recommended were applied. The results showed that the use of fertilizer was significant on the traits such as several leaves per plant, number of seeds per row, number of seeds per ear, plant height and forage yield at 1 % level. The results indicated that the highest forage yield of 33.78 t ha-1 was obtained from the interaction between the use of fertilizers and biological fertilizers, Rhizobium , Azospirillum , Azotobacter and Pseudomonas , which was 42 % higher than control.Для исслСдования влияния химичСских ΡƒΠ΄ΠΎΠ±Ρ€Π΅Π½ΠΈΠΉ ΠΈ Ρ€ΠΎΡΡ‚ΠΎΡΡ‚ΠΈΠΌΡƒΠ»ΠΈΡ€ΡƒΡŽΡ‰ΠΈΡ… Π±Π°ΠΊΡ‚Π΅Ρ€ΠΈΠΉ Π½Π° ΡƒΡ€ΠΎΠΆΠ°ΠΉΠ½ΠΎΡΡ‚ΡŒ ΠΈ качСство Π·Π΅Ρ€Π½Π° ΠΊΡƒΠΊΡƒΡ€ΡƒΠ·Ρ‹ ( Zea mays ) сорта 704 (ΠΎΠ΄ΠΈΠ½ΠΎΡ‡Π½Ρ‹ΠΉ кросс) Π±Ρ‹Π» ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½ Ρ„Π°ΠΊΡ‚ΠΎΡ€Π½Ρ‹ΠΉ Ρ€Π°Π½Π΄ΠΎΠΌΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹ΠΉ Π±Π»ΠΎΡ‡Π½ΠΎΠΉ экспСримСнт с трСмя повторностями Π² 2017 Π³.
