Abstract
The list of forty one subgenera of the genus Andrena from Iran is given. The list provided here is based on a detailed study of all available published data. Four subgenera and five species are recorded for the first time from Iran, including Andrena (Cnemidandrena) fuscipes (Kirby, 1802), Andrena (Lepidandrena) curvungula (Thomson, 1870), Andrena (Lepidandrena) pandellei (Pérez, 1895), Andrena (Parandrena) sericata (Imhoff, 1868) and Andrena (Platygalandrena) tecta (Radoszkowski, 1876). Ecological notes on the newly recorded species are briefly discussed.

Abstract
Sparks of transformation in Persian and Russian literature centered on Nima Yoshij and Alexander Pushkin. Fascinated and loving poets, who firstly love their individuality and secondly love the society in which they live. Poets who cannot bear the suffering of the oppressed people and sit quietly, are looking for a way to sympathize with the people and awaken the mass of the people, Both poets spent a period of their lives in exile because of their liberating thoughts, they are still in exile in love with their homeland and the nature of their land, Sometimes they despair, but they don't let despair stop them from continuing on their way, They try again and find a way to express what needs to be expressed. With their constant presence in their poetry, Nima and Pushkin eliminate the distance between the poem and the poet, bring the poem closer to their time, and actually become one with their own poetry, Nima combines reality with nature, and Pushkin combines reality with history, and they express what needs to be expressed with a new language.

Abstract
Among the 45 collected and identified species, one genus (Scoliocephalus Becker, 1903) and nine species of shore flies (Diptera, Ephydridae) are recorded for the first time in Morocco of which seven species are new to the North African region (Gymnoclasiopa aulisioi (Canzoneri, 1976), Gymnoclasiopa flavoantennata (Strobl, 1900), Hydrellia fascitibia (von Roser, 1840), Philotelma rossii (Canzoneri & Meneghini, 1979), Scatophila mesogramma (Loew, 1862), Scatophila quadriguttata (Meigen, 1830) and Scatophila signata (Loew, 1860)). New data on the distribution of 23 other species are provided: twenty, six and two species are, respectively new for the Rif, the High Atlas, and the Middle Atlas Mountains, whereas one species is new for each of the Central Plateau and the Anti Atlas Mountains. These findings increased the number of Ephydridae species recorded in Morocco to 126 species in 44 genera. They contribute significantly to the understanding of the biodiversity and biogeographical distribution of the Ephydridae family in Morocco and North Africa. The Ephydrids fauna of Morocco account for 6.1% of the world’s known species.

Abstract
Chickpea is an important pulse crop extensively grown in the arid and semi-arid areas of Pakistan. In April 2019, during routine data collection from chickpea fields in NIAB, Faisalabad, a few Convolvulus arvensis plants were observed with symptoms similar to phytoplasma infection. Four symptomatic and two asymptomatic C. arvensis samples were tested for phytoplasma presence using nested-PCR. BLASTn analysis of the obtained sequence and constructed phylogenetic tree confirmed that the detected phytoplasma is clustering with ‘Candidatus Phytoplasma australasia’ subgroup phytoplasma, which was previously reported as associated with a phyllody disease in chickpea and many other crops in Pakistan. The present study reports that, for the first time, C. arvensis is a new host for this phytoplasma in Pakistan, which may act as a primary source of spreading it in important crops.

Abstract
Bio-inoculants have potential role in plant growth promotion. The present study evaluated the potential of Pseudomonas strains as bio-inoculants in wheat on the basis of plant growth promotion and physiological characterization. The 16S rRNA gene sequencing and phylogenetic analysis revealed that four isolated strains belonged to genus Pseudomonas. These strains were positive for phosphorus solubilization and indole acetic acid production, whereas only two strains were positive candidate for their nitrogen fixing ability as determined by presence or absence of nifH gene through amplification from polymerase chain reaction. The pot experiment showed that the integrated use of Pseudomonas strains as co-inoculant and 50% applied mineral fertilizers enhanced the maximum wheat growth and development from 58 to 140% for different shoot and root growth parameters. The strain NCCP-45 and NCCP-237 were closely related to Pseudomonas beteli and Pseudomonas lini, respectively. These isolated strains can be used to increase crop productivity by using as a bio-fertilizer inoculum.

Abstract
Participatory Irrigation Management (PIM) has emerged as a significant intervention in which farmers are given more control over irrigation management. The primary goal of this study was to identify the factors that influence farmers' participation in PIM activities and compare the economic viability of participation levels. A multi-stage random sampling technique was used to collect the data from 240 farmers of Nasrana and Maduana distributaries located at the tail end of the Lower Chenab Canal (LCC) west circle in district Faisalabad, Punjab, Pakistan, using a structured questionnaire. The factors influencing farmers' participation in PIM activities were identified using an ordered Probit Regression model. The findings revealed that education level (β= 0.12; P=0.00), village leadership (β= 0.97; P= 0.00), and being a beneficiary of a water user association (β=1.20; P= 0.00) all had a significant positive influence on farmers' participation in PIM activities. On the other hand, family size (β= -0.05 P= 0.04), land ownership (β= -0.44; P= 0.05), and off-farm income (β= -0.52; P= 0.01) were found to have a significant negative impact on farmers' participation. Farmers with a high level of participation had higher farm technical efficiency and crop productivity. For these reasons, farming communities must be encouraged to participate in PIM activities in order to achieve a sustainable irrigation system.
