In 2019 there were forest fires in Sumatra, Indonesia, which co-occurred with a strong positive IOD. The forest fire disaster caused the thick smoke containing dusts such as particulate matter with a size of 2.5 μm (PM2.5). In this study, a model simulation was conducted to predict the distribution of PM2.5 using the WRF–Chem model when forest fires in 2019 occurred. The prediction was produced by adding the latest version of fire inventory from NCAR (FINN) input data, version 2.5. The prediction result was verified and compared with ground station data from the Ministry of Environment and Forestry (KLHK) station and NASA’s EOSDIS satellite imagery. There are three ground stations that were used for verification: the Jambi, Palembang and Pekanbaru stations. Of the three stations, the prediction results at the Palembang station are the best in correlation and RMSE value. Spatially, the distribution of PM2.5 from the model result is similar and can follow the pattern of smoke distribution from satellite imagery observations. Even though, generally the WRF–Chem model equipped with the latest FINN data still cannot produce an accurate prediction for the 2019 forest fires event yet in Sumatra region.
Modelling population dynamics of Orius laevigatus and O. albidipennis (Hemiptera: Anthocoridae) to optimize their use as biological control agents of Frankliniella occidentalis (Thysanoptera: Thripidae)
Authors: Sanchez J.A. , Lacasa A. 
Published: August 2023

AbstractOrius laevigatus (Fieber) and O. albidipennis (Reuter) play an important role in the control of Frankliniella occidentalis (Pergande) in crops and natural vegetation in the Mediterranean area. The biological parameters of the two anthocorids were studied and modelled in relation to temperature to optimize their use in thrips control programmes. Development times and reproductive parameters of O. laevigatus and O. albidipennis were determined at 20, 25, 30 and 35°C. Pre-imaginal development times ranged from 34.6 and 37.2 days at 20°C to 12.3 and 10.2 days at 35°C in O. laevigatus and O. albidipennis, respectively. The lower thermal development threshold was significantly higher for O. albidipennis (14.2 ± 0.9°C) than for O. laevigatus(11.3 ± 0.7°C). No significant differences in fecundities between the two anthocorids were observed at 20, 25 and 30°C. At 35°C, O. albidipennishad a significantly higher fecundity than O. laevigatus. Non-linear models were used to explain reproduction and female survivorship in relation to temperature. The upper reproductive thresholds were estimated at 40.9 ± 0.3 and 35.5 ± 0.1°C for O. albidipennis and O. laevigatus, respectively. The different optimum temperatures may explain, at least in part, the different distributions of the two species in the Palaeartic region and their population dynamics in greenhouses and natural vegetation in the south of Spain. The estimation of rmas a function of temperature showed high variability between years. Three release rates of 0.75–0.25 Orius per plant are recommended from early March to mid May to deal with thrips outbreaks in pepper crops.
Mitochondrial DNA sequence divergence among Schizaphis graminum (Hemiptera: Aphididae) clones from cultivated and non-cultivated hosts: haplotype and host associations
Authors: Anstead J.A. , Burd J.D. , Shufran K.A. 
Published: August 2023

AbstractA 1.0 kb region of the mitochondrial cytochrome oxidase subunit I gene from the greenbug aphid, Schizaphis graminum (Rondani), was sequenced for 24 field collected clones from non-cultivated and cultivated hosts. Maximum likelihood, maximum parsimony and neighbour-joining phylogenies were estimated for these clones, plus 12 previously sequenced clones. All three tests produced trees with identical topologies and confirmed the presence of three clades within S. graminum. Clones showed no relationship between biotype and mtDNA haplotype. At least one biotype was found in all three clades, suggesting exchange among clades of genetic material conditioning for crop virulence, or the sharing of a common ancestor. However, there was a relationship between host and haplotype. Clade 1 was the most homogenous and contained 12 of 16 clones collected from cultivated hosts and five of the six collected from johnsongrass, Sorghum halepense, a congener of cultivated sorghum, S. bicolor. Four of the six clones collected from Agropyron spp. were found in clade 2. Clade 3 contained two clones from wheat, Triticum aestivum, and four from non-cultivated hosts other than Agropyron spp. A partitioning of populations by mtDNA haplotype and host suggests the occurrence of host adapted races in Schizaphis graminum.

Published: August 2023

AbstractInsects migrating over two sites in southern UK (Malvern in Worcestershire, and Harpenden in Hertfordshire) have been monitored continuously with nutating vertical-looking radars (VLRs) equipped with powerful control and analysis software. These observations make possible, for the first time, a systematic investigation of the vertical distribution of insect aerial density in the atmosphere, over temporal scales ranging from the short (instantaneous vertical profiles updated every 15 min) to the very long (profiles aggregated over whole seasons or even years). In the present paper, an outline is given of some general features of insect stratification as revealed by the radars, followed by a description of occasions during warm nights in the summer months when intense insect layers developed. Some of these nocturnal layers were due to the insects flying preferentially at the top of strong surface temperature inversions, and in other cases, layering was associated with higher-altitude temperature maxima, such as those due to subsidence inversions. The layers were formed from insects of a great variety of sizes, but peaks in the mass distributions pointed to a preponderance of medium-sized noctuid moths on certain occasions.
Histological studies of damage by pod-sucking bugs (Heteroptera: Coreoidea) associated with cowpea Vigna unguiculata ssp. unguiculata in Nigeria
Authors: Soyelu O.L. , Akingbohungbe A.E. 
Published: August 2023

AbstractHistological studies were conducted on cowpea pods fed upon by the coreoid pod-sucking bugs, Anoplocnemis curvipes (Fabricius), Clavigralla tomentosicollis Stå;l, C. shadabi Dolling, Riptortus dentipes (Fabricius) and Mirperus jaculus (Thunberg). Various degrees of tissue and cellular disruption were apparent, especially in the brachysclereids. They were manifested in terms of plasmolysis, cell enlargement and cell wall disintegration depending on the coreoid species involved. The feeding site and its periphery had all the cells of the brachysclereids plasmolysed, with the parenchyma having broken cell walls in the case of A. curvipes. Riptortus dentipes and M. jaculus showed similar patterns of feeding activity but less extensive levels of damage. The Clavigralla spp., however, caused cell enlargement in the brachysclereids, and broken cell walls in both the brachysclereids and the parenchyma. Damage symptoms were observed in cells far away from the feeding sites of the bugs, suggesting the possibility of sucrase activity which has been reported to cause osmotic pump feeding in the Coreidae.
Selecting the right statistical model for analysis of insect count data by using information theoretic measures
Authors: Sileshi G. 
Published: August 2023

AbstractResearchers and regulatory agencies often make statistical inferences from insect count data using modelling approaches that assume homogeneous variance. Such models do not allow for formal appraisal of variability which in its different forms is the subject of interest in ecology. Therefore, the objectives of this paper were to (i) compare models suitable for handling variance heterogeneity and (ii) select optimal models to ensure valid statistical inferences from insect count data. The log-normal, standard Poisson, Poisson corrected for overdispersion, zero-inflated Poisson, the negative binomial distribution and zero-inflated negative binomial models were compared using six count datasets on foliage-dwelling insects and five families of soil-dwelling insects. Akaike's and Schwarz Bayesian information criteria were used for comparing the various models. Over 50% of the counts were zeros even in locally abundant species such as Ootheca bennigseni Weise, Mesoplatys ochroptera Stål and Diaecoderus spp. The Poisson model after correction for overdispersion and the standard negative binomial distribution model provided better description of the probability distribution of seven out of the 11 insects than the log-normal, standard Poisson, zero-inflated Poisson or zero-inflated negative binomial models. It is concluded that excess zeros and variance heterogeneity are common data phenomena in insect counts. If not properly modelled, these properties can invalidate the normal distribution assumptions resulting in biased estimation of ecological effects and jeopardizing the integrity of the scientific inferences. Therefore, it is recommended that statistical models appropriate for handling these data properties be selected using objective criteria to ensure efficient statistical inference.

Published: August 2023

AbstractInformation on longevity and on the effect of ageing on pheromone signalling in Bostrichidae infesting stored products is important because pheromones play a crucial role in mediating aggregation by the species in storages. The longevity of starved and unstarvedProstephanus truncatus(Horn) andRhyzopertha dominica(Fabricius) were determined at 28±1°C, 65±2% RH and L12:D12 cycle. Additionally, the effects of ageing on rate of pheromone emission were investigated inR. dominicaby comparing emission rates of the aggregation pheromones Dominicalure-1 (DL1) and Dominicalure-2 (DL2) released by adult males ranging from 4, 8, 12, 24 and 48 weeks of age. Mean survival time of starved male and femaleP. truncatuswas 8.6±0.6 and 9.1±0.4 days, respectively. StarvedR. dominicamales lived for 5.7±0.2 days, and females for 4.7±0.1 days. However, mean survival times were not significantly different for starved males vs. females of either species. Mean survival time of unstarved male and femaleP. truncatuswas 27.5±2.0 and 18.0±3.3 weeks, respectively, and for unstarved male and femaleR. dominicawas 26.1±2.8 and 16.7±2.9 weeks, respectively. Difference in mean survival times of unstarved males vs. females in bothP. truncatusandR.dominicawere significant. Between species, no significant difference was observed in mean survival time between unstarved males ofP. truncatusorR. dominica, nor between females of both species. Rate of pheromone emission inR. dominicawas higher when the insects were relatively young (4, 8 and 12 weeks old), but declined by almost 55% in treatments where the insect were at about 24 or 48 weeks old, suggesting that recruitment potential ofR. dominicamight reduce substantially as the insects age.

AbstractEnvironment-friendly farming techniques seek to increase invertebrate biodiversity in part with the intention of encouraging greater numbers of predators that will help to control crop pests. However, in theory, this effect may be negated if the availability of a greater abundance and diversity of alternative prey diverts predators away from feeding on pests. The hypothesis that access to alternative prey can lead to reduced pest suppression under semi-field conditions was tested. Alternative prey type and diversity were manipulated in 70 mesocosms over 7+ weeks in the presence of the carabidPterostichus melanarius(Illiger), a known predator of slugs, and reproducing populations of the slugDeroceras reticulatum(Müller). Significantly fewer slugs survived where no alternative prey were provided. Maximum slug numbers and biomass were found in treatments containing either carabids plus a high diversity of alternative prey (many species of earthworm and three of Diptera larvae) or a single additional prey (blowfly larvae,Calliphora vomitoriaLinnaeus). In these treatments slug numbers and biomass were as high as in plots lacking predators. The effects of alternative prey were taxon-specific. Alternative prey strongly affected carabid fitness in terms of biomass and egg load. The fittest predators (those with access to high alternative prey diversity orC. vomitorialarvae) reduced slug numbers the least. The mean individual slug weights were greater in treatments with alternative prey than where no alternative prey were provided to the carabids. These results suggest that pests may survive and reproduce more rapidly in patches where predators have access to alternative prey.

Published: August 2023

Abstract
As a non-contact, couplant-free and nondestructive technique, the laser ultrasonic technology has great potential for detecting surface defects. In this paper, we propose a surface defect identification method based on broadband laser-generated Rayleigh wave with wavenumber filtering in an area scanning mode. Firstly, a particular lowpass filter is constructed in frequency-wavenumber domain to extract the scattered wave generated by the defects, and then a surface defect image can be reconstructed based on the broadband scattered wave wavenumbers. Secondly, a threshold denoising method is employed to enhance the signal-to-noise ratio and improve the image sharpness. Thirdly, the experimental validation is carried out, in which a laser ultrasonic detection system is used to detect the surface defects of aluminum alloy specimens and identify their different parameters. The experimental results verify that the proposed method can identify the location, size and orientation of surface defects effectively, meanwhile, its imaging effect shows significantly superior to that of the conventional reflected wave energy and standing wave energy methods. Furthermore, the correlation between maximum local scattered wave energy and the depth of defects is found, which can characterize the severity of the surface defects.

Authors: Tian Weixin , Chai Junrui , Cao Jing 
Published: August 2023

Abstract
This study looked into the way graphene oxide (GO) affects the porosity and thermal conductivity of composite materials fabricated from cement. Different concentrations ascribed to GO at 0.02%, 0.05, 0.07, and 0.1% were added to the cement samples (as per cement mass). The porosity showed a trend of first decreasing and then increasing, with the decrease in macroporosity being particularly pronounced. The porosity and thermal conductivity of GO-cement composites were measured. The findings demonstrated by incorporating GO, the thermal conductivity of GO-cement composites was firstly boosted, which later decreased with the largest enhancement at 0.02%. This study holds the promise of providing a basis for GO’s multi-field coupling of cement under multiple enhancements of mechanics, heat conduction, and hydration and contributing significantly to the application of GO.

Authors: Miao Teng , Liu LinSheng 
Published: August 2023

Abstract
In this paper, InAs, GaAs, and InGaAs nanowires are grown by CVD using a dual-temperature zone tube furnace. The grown nanowires are characterized and analyzed. Based on the traditional chemical vapor deposition method, a small quartz tube is innovatively used to first deliver group III materials to fuse with gold particles, thus forming a higher quality eutectic alloy. It then pushes in InAs and GaAs source materials for normal growth. With growing InGaAs nanowires, the source temperature of InGaAs nanowire growth is controlled by using a dual-temperature zone to achieve the control of InGaAs nanowire components.

Authors: Lu Yimiao , He Bo , Sun Yufei , Wang Jinbao 
Published: August 2023

Abstract
Considering the viscoelastic of soft clay, the fractional kelvin model is used to describe the constitutive relationship of soft clay. At the same time, considering that both sides of the soft clay layer have certain permeability, the two-sided semi-permeable boundary is used as its boundary condition. Combined with the cyclic load of different waveforms, the one-dimensional consolidation settlement of saturated soft clay is analyzed. Firstly, the consolidation equation is obtained through Laplace transformation, and the semi-analytic result is obtained by Laplace inverse transformation. The accuracy of the solve method and the model’s applicability are checked by the degradation of boundary conditions and the model. Finally, one-dimensional consolidation settlement under cyclic load with different waveforms is compared.

Authors: Hou Lanxin , Hu Yifeng 
Published: August 2023

Abstract
In this paper, the Gurson-Tvergraad-Needleman (GTN) model is used to study the damage of stainless steel springs at high temperatures. The basic material and GTN damage parameters are determined from the stress-strain curves of tensile tests. Then the damage evolution of springs at 300 °C to 900 °C is analyzed based on finite element simulations. The results show that below 600 °C, the change of volume fraction of holes in the spring, along with the increase of load, has an obvious low growth stage, followed by a rapid growth stage. But above 600 °C, there is only a stable and rapid growth stage. The fracture positions predicted by finite element damage analyses agree with the experiments for round bars.

Abstract
In 2011, a serious nuclear accident occurred in Fukushima, Japan, and one of the major causes was the destruction of the cladding material mainly made of Zr alloy due to a violent chemical reaction with high-temperature water vapor. Since then, scholars in various countries have been trying to find a better nuclear fuel cladding material. Because of its high temperature strength, ferritic/martensitic(F/M) steel is used in thermal power units. Over the past hundred years, the high temperature performance of ferritic/martensitic steel has developed simultaneously with the operating temperature of thermal power system. F/M steel is widely used in nuclear power system as well as thermal power, The fatigue life of nuclear fuel cladding material is an important parameter to study its service life, due to the special shape of the cladding material, especially for the pipe with a thickness of less than 0.5mm, it is difficult to directly measure its mechanical properties, this paper through special experimental materials and fixtures F/M pipe steel at room temperature and high temperature tensile test, as well as low cycle fatigue performance test, and its fracture port, surface crack analysis. Through the analysis and processing of experimental data, typical stress-cycle life curves, total strain amplitude-life curves, elastic strain amplitude-life curves, hysteresis curves with different strain amplitudes, and fatigue life prediction curves were obtained.

Authors: Lai Fuming , Zhao Min , Tong Shengfu 
Published: August 2023

Abstract
The Wulff construction methodology proves to be a highly useful approach in predicting the morphologies of nanoparticles. However, this approach requires the precise determination of surface energies for all orientations, which can be a challenging task due to the inherent complexity of measuring surface-free energies. In this work, the inverse Wulff construction is employed to effectively predicted surface energies from brookite TiO2 particle morphologies. This method can provide guidance for researchers to understand how to control the brookite TiO2 crystal morphology according to the synthetic method used.

Abstract
Strong blasting disturbance leading to damage or even destruction of weak and fractured rock masses is a crucial problem to be solved during the construction process of underground engineering. For the blasting construction problem of advanced consolidation grouted rock near the excavation contour, the safety effect of blasting shock waves on grouted rock is investigated using a theoretical analysis method. The interaction process between blasting shock waves and grouted rock was studied based on the propagation characteristics of shock waves and the strain rate effect of rock strength. Considering the critical failure state, a safe vibration velocity model was established to analyze the effects of proportional distance, age, and grouting material. Results show that the first transmission and reflection effect creates the most dangerous state for grouted rock. SVV of super rapid strengthening cement is larger than that of ordinary cement. Choosing a suitable grouting material is essential to the following blasting design.

Abstract
In recent years, all inorganic perovskites have proven to be excellent photocatalytic materials. However, its poor stability and severe recombination of photogenerated electrons and holes have hindered its wide application. Herein, we employed a convenient and rapid one-pot sonochemical method to incorporate CsPbBr3 into Pb-MOF, aiming to enhance the stability and efficiency of photogenerated electron transfer. The CsPbBr3@Pb-MOF shows good photocatalytic efficiency, and 70% tetracycline hydrochloride (TCH) water solution is decomposed at 60 min visible light (λ>420 nm) irradiation. Meanwhile, CsPbBr3@Pb-MOF exhibits excellent photocatalytic stability.
