Abstract
Abstract The aphid parasitoids, Aphidius colemnai Viereck and A. matricariae (Haliday) (Hymenoptera: Braconidae: Aphidiinae) have high potential as the most effective biological control agents for controlling the cotton aphis Aphis gossypii Glover (Hemiptera: Aphididae). In this investigation, the effect of five constant temperatures (10, 15, 20, 25 and 30 °C) on the reproductive parameters was studied at 65 ±5% relative humidity and a photoperiod of 16L: 8 D hours In this study, the newly laid (one- day old) eggs were reared on third instar nymphs of cotton aphid, and the pupal and adult stages of the parasitoids were recorded daily, until the last individual was found dead. The experiments were carried out with 15 replications at each temperature. The results revealed that the gross fecundity and fertility rates were significantly different at all tested temperatures for both species (P

Abstract
To determine the effective bio-control agents of water fern, Azolla filiculoides, adults and nymphs of water lily aphid, Rhopalosiphum nymphaeae (L.), were collected on A. filiculoides in Guilan Province, Iran, during October 2013. This aphid has been collected extensively from almost all water fern samples during 2013 and 2014. Although R. nymphaeae was reported from numerous host plants in Iran, this species was collected for the first time from water fern. This aphid is heteroecious holocyclic with a sexual phase on Prunus spp., but it is the first report of its sexual phase formation on water fern as secondary host plant.

Abstract
Research Subject: In recent years, smart water flooding has gained attention regarding enhanced oil recovery, and one of its driving mechanisms is wettability alteration. However, the effect of acid presence on smart water performance needs to be clarified. Thus, the main question is whether the presence of acid and potential determining ions can lead to further wettability alteration and interfacial tension (IFT) reduction. Additionally, in this study, trivalent cations were added to smart water for the first time, and the results were compared with those of divalent cations.
Research approach: In this study, seawater (SW), 4-times diluted SW, and 8-times diluted SW were prepared in distilled water, 0.001 normal HCl and 0.01 normal HCl, and the contact angle and IFT experiments were carried out. In addition, concentrations of Ca2+, Mg2+, and Fe3+ were adjusted in 8-times diluted SW prepared in 0.01 normal HCl, and the IFT and contact angle tests were conducted.
Main Results: The results showed that the presence of acid in distilled water could decrease the IFT values; however, it did have a marginal effect on contact angle reduction. Also, because of synergistic effects between acid and potential determining ions, IFT significantly declined. While adding acid to brines with different salinities resulted in contact angle reduction, the glass surface remained oil-wet. Regarding divalent and trivalent cations, the results revealed that increasing Fe3+ concentration in smart water made the glass surface water-wet. However, adjusting Ca2+ and Mg2+ concentrations changed the wettability from oil-wet to neutral-wet. Moreover, divalent and trivalent cations showed similar behavior in IFT reduction, and a four-times increase in the concentration of each mentioned ion reduced IFT by about 2 mN/m.

Abstract
Hypothesis: One potential method for improving nanocomposite mixed matrix membranes is through the use of nanoparticles and compounds containing hydroxyl and carboxyl groups, which may aid in the penetration of CO2 gas. In this study, we investigated the selectivity and permeability of a polyether block amide/polyvinyl alcohol (Pebax/PVA) nanocomposite membrane containing magnesium oxide (MgO) nanoparticles. Previous research has shown that the addition of MgO to the Pebax/PVA matrix can increase CO2 permeability by creating an intermolecular space.
Methods: Prepared a Pebax/PVA nanocomposite membrane with a weight ratio of 80:20, containing 10% MgO nanoparticles, through a solution casting method. Evaluated the performance of the Pebax/PVA/MgO nanocomposite membrane for separating CH4 and CO2 gases using various tests.
Findings: Characterized the membranes through Fourier transform infrared (FTIR), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM) tests. FESEM images showed increased surface roughness with the addition of nanoparticles, and the nanoparticles were well dispersed within the polymer matrix. XRD analysis indicated that MgO nanoparticles had more interaction with PVA chains than with Pebax chains, and peaks at 42° and 62° regions were formed due to the placement of MgO nanoparticles among the polymer chains. We studied various parameters, including polyvinyl alcohol and MgO nanoparticle content, pressure, and temperature, as independent variables and examined their effects on the permeability of CH4 and CO2 gases. We measured the permeability of the constructed membranes and found that the addition of MgO significantly increased the permeability of CH4 and CO2.

Abstract
The water fern weevil, Stenopelmus rufinasus Gyllenhal (Coleoptera: Curculionidae), is considered as the most important biological control agent of Azolla spp. in the world. Azolla spp. was introduced in Iran in 1986. In August 2017, two specimens of S. rufinasus were collected on Azolla spp. in waterways near Anzali lagoon and Rice Research Institute of Iran (RRII) in Guilan province for the first time. Identification was based on molecular sequencing. This is the first record of S. rufinasus from Iran.

Abstract
Purpose: Scorpions in the Middle Eastern countries are known as the most widely spread poisonous creatures that cause casualties and death to human being and domestic animals. These creatures are distributed and well established in subtropical regions.
Among sixteen Iranian islands in the Persian Gulf, Kish Island is the focus of important internal and foreign industrial and commercial activities, attracting, thousands of tourists willing to visit its natural beauties and site seeing places every year. The present study was carried out during 1998-99 throughout Kish Island in order to learn about the species, abundance and foci of distribution of scorpions. This was done to establish a control strategy, reduce scorpion stings, and safeguard visitors, as well as, local population.
Materials and methods: Collections were made using the night search using the direct smapling method with a UV light.
Result: A total of 371 scorpions were captured. These were identified as Buthotus jayakari 365 specimens (%98.38) and Buthacus leptochelys with only 6 specimens (%1.68) belonging to the Buthidae family. B. jayakari was collected in most parts of the island and was considered to be the dominant species. The sex ratio was 1:1.53 in favor of females. Whereas B. leptochelys was a rare species having a restricted distribution.
Discussion: Considering the high population of B. jayakari and its wide spread distribution, it can be regarded to be responsible for the majority of scorpion-stings in Kish Island.
