Here we report the presence of Cybocephalus nipponicus Endrödy-Younga, 1971 from Iran, which has been collected on mulberry in Gilan province, as well as on bitter orange and Japanese spindle in Mazandaran province, northern Iran. The specimens were collected while feeding on scale insects, Pseudaulacaspis pentagona (Targioni Tozzetti, 1886), Unaspis euonymi (Comstock, 1881) and Lepidosaphes gloveri (Packard, 1869) (Hemiptera: Diaspididae). Photos of habitus and genitalia with some taxonomic comments are presented.

To date, Kazakhstan is an underexplored territory regarding the study of leaf miners. This article aims to present new data on the defoliators of silver birch (Betula pendula Roth) in cultivated plants of North-Eastern Kazakhstan (the Pavlodar Region). Occurrence of Fenusa pumila Leach, 1817, as well as additional new data on the previously known leafminer species are presented for the first time for the Pavlodar Region. Groups of birch-defoliating insects were chosen as model objects. The research conducted in the territory of the Pavlodar Region revealed six species of leaf miners belonging to three genera Stigmella Schrank, 1802, Phylloporia Heinemann, 1870, and Fenusa Leach, 1817. All representatives are obligate miners that develop at the larval stage in the mesophyll of birch leaves. This group of insects harmfully affects plants, often causing their death, which in turn proves the importance of studying them.

Diversity, community structure, and estimation of flower fly species richness (Diptera: Syrphidae) were measured in Darab damask rose plain, Fars province, Iran. Four Malaise traps were installed in a nearly 500-hectare site from April to October 2019 and checked periodically. The 4-step integrated approach was used to assess the sample completeness profile, to infer true diversities of entire assemblages, to standardize the sample coverage, and to infer diversity via an evenness profile. To estimate the species richness of the Syrphidae community, two models and seven non-parametric indices were used. As a result, a totally of 96 specimens representing 18 species were collected in 18-Malaise trap months (MTM) sampling efforts. One species, Paragus auritus Stuckenberg, 1954 was recorded for the first time from Iran. The aphidophagous hoverflies included 76.3% of all collected specimens. The dominant species were Sphaerophoria scripta (Linnaeus, 1758), Eupeodes corolla (Fabricius, 1794), and Eumerus ahmadii Barkalov & Gharali, 2004. The estimated sample completeness profile showed that our data covers 85% of the total species in this community. Shannon and Simpson diversity indices are measured at 10.88 and 7.04, respectively. The models and non-parametric estimators estimated the species richness of syphids varied from 19 – 24 species. The biodiversity of Syrphidae community in the world's largest rain-fed organic damask rose plain, located at high altitudes of ca. 2600 m a.s.l. of the Zagros Mountains ranges in the south of Iran, provides fundamental data for any future conservation efforts of pollinators and predators and biocontrol programs of sucking pests.

This paper reports a new addition to the national bumblebee fauna of the Indian Himalayas. The newly recorded species viz., Bombus cryptarum (Fabricius, 1775) (Hymenoptera, Apidae) is fully described from the Gurez Valley (Jammu and Kashmir) and Panamik (Ladakh) in the Western Himalayan range. Males of the B. cryptarum have thoracic dorsum and T2 lemon yellow without black hairs. Gonostylus with the anterior apical process with long hairs and penis valve greatly broadened and flared outwards. With the addition of a new record, the Indian Himalayan region is now represented by 57 species of bumblebees. The species diagnosis, current distributional range, and host plants of this species are also provided.

The book "Lepidoptera Iranica" is a comprehensive and meticulously researched publication that explores the butterfly and moth fauna of Iran. Edited by Hossein Rajaei and Ole Karsholt, the book includes contributions from seventy-three Iranian and international researchers over 13 years. The book provides a historical review of lepidopterology in Iran and discusses the general patterns of Lepidoptera fauna in the country. It also estimates the number of Lepidoptera species waiting to be discovered in Iran and includes a gazetteer of elusive localities of Iranian Lepidoptera records. The final chapter is a comprehensive catalogue of the Lepidoptera of Iran, including a checklist of all 4,812 known species, as well as information and notes on their taxonomy, distribution, and biology. The book serves as an important tool for scholars, preservationists, and enthusiasts, and highlights the importance of continued research and conservation efforts in the country.

The current study gives more information on Lepidoptera (butterfly) diversity and their food plant resources in the conifer woods of Shimla Water Catchment Wildlife Sanctuary, Himachal Pradesh. The study was carried out during the three distinct seasons; summer, monsoon, and autumn from March 2019–April 2022. A total of 1650 butterflies, representing 68 species and 6 families were recorded. The Nymphalidae comprised the greatest number of species (28 species), followed by the Lycaenidae (15), Pieridae (13), Papilionidae (7), Hespiradie (4) and Riodinidae (1). Species abundance and richness were more in mixed forest type which owing water and grass-cover availability supported most unique butterfly assemblages as compared to pure conifers and oak forest. The months from April to November harbor the greatest abundance of species. An overall reduction in species abundance was seen from December through January and until the end of March. This study provides an understanding of butterflies and has inspired additional investigation for the restoration of forest habitats in this protected area. The current study on diversity shows the importance of preserving biodiversity and monitoring climate change. It offers a basic identification, gathers data from a comparative viewpoint, allows synthesis, and develops and stimulates ideas and hypotheses that are applicable to other fields.

A vast number of tropical and subtropical mites belong to the family Tarsonemidae Canestrini & Fanzago, 1877, with the tribe Tarsoenmini under subfamily Tarsoneminae having the most diverse assemblage. In order to better understand the distribution, community structure, and host specificity of these mites, it is important to investigate the Tarsonemini mite fauna of India, particularly in the highly biodiverse state of West Bengal. A total of 1154 mite specimens were obtained from 69 distinct plant species belonging to 44 families and distributed over six agroclimatic zones in West Bengal. The mites were classified into 8 distinct genera and 38 morphospecies. We developed bipartite trophic networks for Tarsonemini mites for the first time to show how these different communities of these mites are associated to various host plant species in six different agroclimatic zones. Different network descriptors such as Connectance, H2, Niche Overlap and Robustness were calculated from the mite-plant networks of six agroclimatic zones. Northern Hill Zone had the highest diversity followed by New Alluvial and Teesta-Terai Zone whereas, Red Laterite Zone had the least diversity of mite species. More than 70% Tarsonemini mites were found as generalist plant inhabitants which is consistent with their epiphytotic microbivorous feeding strategy.

Here, the species richness of Campopleginae, a diverse subfamily of the Darwin wasps was studied in an almost organic damask rose plain located at 2600 m a.s.l., the south of Iran. Sampling was done using four Malaise traps for six months from April–October 2019. The total sampling efforts were 18 trap months. The integrated approach was used to assess the sample completeness profile, to infer true diversities of entire assemblages via asymptotic diversity estimates, to standardize the sample coverage via rarefaction and extrapolation, and to infer diversity via an evenness profile. I also used Homogenous, Homogenous (MLE), Chao1, Chao1-bc, iChao1, ACE, ACE-1, 1st order jackknife, and 2nd order jackknife to estimate the species richness of the studied Campopleginae community. Malaise traps yielded 491 individuals belonging to 24 morphospecies. Diadegma majale (Gravenhorst, 1829) included 64.7% of the total individuals collected, representing the highly dominated species. The estimated sample completeness profile showed that our data covers 59% of the total species in this community and thus 41% of species are undetected. The values for Shannon and Simpson diversity indices are 4.53 and 2.29, respectively. The models and non-parametric estimators estimated the species richness of Campoplegines from 24 – 50 species. This study provides a wealth of baseline data for the subfamily Campopleginae in the south of Iran in terms of biological control and conservation.

The aim of this study is to make an inventory of the fauna of the Odonata in Theniet El Had National Park, which helps managers to make appropriate decisions for the conservation of these species. The site is entirely forested (Cedrus and Quercus species) with numerous intra-forest natural environments (clearings, grasslands, rocky habitats, springs, pools and ponds, etc.), this mosaic of habitats harbours a remarkable wealth of fauna and flora. Our study focused on the natural and artificial temporary forest ponds, scattered throughout the park, which are of biological and ecological interest for a very wide range of insects, most notably the hemimetabola. These are characterised by a larval stage that is quite different from the adult stage in terms of habitat and lifestyle, namely odonates, where the larvae are aquatic whereas the adults have an aerial life. The inventory of odonates was carried out through monthly surveys of 8 water bodies (7 forest ponds and one hill reservoir) during one year, from March 2017 to February 2018. This preliminary inventory allowed us to inspect 240 individuals of odonates belonging to 18 species i.e. 11 genera and 5 families. The species recorded at the end of this study are the subject of a cartographic representation showing their distribution at the local scale (in the park) and at the national scale.

The fall webworm, Hyphantria cunea (Drury, 1773) (Lepidoptera, Erebidae), is one of the most important pests of forest trees in northern Iran. In order to identify the native parasitoids of this pest a survey was conducted in Guilan province, in 2019. The larvae and pupae of the fall webworm suspected being parasitized, were collected from different host trees and wood piles, and reared under laboratory conditions until the parasitoids emerged. This pest was found parasitized with five species of Hymenoptera, Brachymeria lasus (Walker, 1841) (Chalcididae), Chouioia cunea Yang, 1989 (Eulophidae), Psychophagus omnivorus (Walker, 1835) (Pteromalidae), Pimpla rufipes Brulle, 1846, Virgichneumon dumeticola (Gravenhorst, 1829) (Ichneumonidae), and four species of Diptera, Compsilura concinnata (Meigen, 1824), Exorista larvarum (Linnaeus, 1758), Pales sp. (Tachinidae), and Megaselia scalaris (Loew, 1866) (Phoridae). Among them six species (e.g., P. rufipes, V. dumeticola, B. lasus, E. larvarum, C. concinnata and Pales sp.) are newly reported as the parasitoids of H. cunea from Iran.

Chalcidoidea play an important role in the biological control of many agricultural pests. The present study determines and compares the diversities of this superfamily in four ecosystems in the Lake Urmia basin. It is the largest hypersaline lake in the world with a large basin of different ecological conditions in northwest Iran. These stations were: Khajeh (K) and Tasuj (T) in Lake Urmia Basin (LUBin) and Khoda-Afarin (KA) and Tikme-Dash (TD) out of their (LUBout). Four months of Malaise trapping in these habitats resulted in a total of 512 specimens from 11 families of Chalcidoidea, including 6, 9, 10 and 10 families in K, KA, T and TD, respectively. Maximum abundance was observed in the T station with 192 and the minimum was in the K station with 38. However, the families, Encyrtidae and Chalcididae have maximum abundance in T and KA, respectively. The maximum activity of chalcidoid wasps was observed during June-August. The majority of the species were belonging to the family Mymaridae (25%), in LUBout habitats peaked at 47 specimens in TD during the sampling period, while the corresponding LUBin habitats peaked at 40 specimens in T. The two LUBout habitats had greater community similarity (60%) than found between in and LUBout habitats (42%) and diversity of chalcidoid wasps in LUBout was found much more than LUBin. Biodiversity studies showed that the KA station has the greatest values of diversity, evenness, and richness of Chalcidoidea. This station is located outside of Lake Urmia basin with the warmest and most humid climate and forest ecosystem on the margins of the Aras River.

Intercropping is defined as the simultaneous cultivating of two or more crops together at the same time within a field. It has many advantages like pest population reduction, which increases crop yield. This study compared the impact of additive intercropping kidney bean Phaseolus vulgaris L. with some aromatic plants on Thrips tabaci Lindeman, 1889 population. The treatments included kidney bean sole crop, 100 + 50 kidney bean + coriander Coriander sativum L., 100 + 50 kidney bean + ajwain Carum copticum L., 100 + 50 kidney bean + basil Ocimum basilicum L., and 100 + 50 kidney bean + dill Anethum graveolens L. There were six sampling dates at weekly intervals after onion thrips emergence on the leaves. Kidney and bean leaves were collected on each sampling date, and the number of thrips larvae or adults was recorded. Results showed that the intercropping system significantly influences the onion thrips population. The minimum and maximum thrips per leaf were recorded in kidney bean + basil mixed and kidney bean sole crop treatments (0.208 and 0.540 Thrips/leaf). Moreover, there was a significant negative relationship between the number of thrips and kidney beans yield. The highest yield was recorded in kidney bean + basil treatments (2756 kg/ha). Besides, intercropping increased the Land Equivalent Ratio (LER) of bean monoculture. For instance, all intercropping treatments had higher LER than kidney bean monoculture. Among the intercropping treatments, the kidney bean + basil treatment had the highest LER (1.433). Finally, intercropping kidney beans with some aromatic plants could be an eco-friendly strategy in integrated pest management.

Butterflies are flagship taxa and bio-indicator of terrestrial ecosystems. Studies of butterflies are performed in different regions of Nepal, but no detailed research has been carried out in Tanahun. Hence, this study was conducted to determine the species diversity and abundance of butterflies in Byas municipality-6 of the Tanahun, Nepal, from March to November 2020. The Pollard walk method was used for the data collection. A total of six transects of 500 m, two in each habitat type (forests, settlements, and agricultural lands), were laid out randomly. The study was performed in three seasons (9 months); Pre-Monsoon (March to May), Monsoon (June to September), and Post-Monsoon (October to November). Each transect was surveyed nine times (once a month) to record species in each month. Data were pooled and analyzed with SPSS. A total of 1,753 individuals of 149 butterfly species from 92 genera and six families were recorded during the study. The overall Shannon-Wiener and Margalef diversity indices were H = 4.17 and R = 19.95. Pielou’s Evenness was E = 0.83. Nymphalidae was the most diverse, richest species, and most abundant family (H = 3.33, R = 8.30, N = 851). Species evenness was maximum in the family Papilionidae (E = 0.88). The forests comprised the maximum number of species (115 species, 898 individuals). The maximum number of species was recorded in March (106 species), while the highest species abundance was in June (268 individuals). The result of this study could be the baseline for further researches on butterflies in the Tanahun district.

Increasing roads become the serious conservation threats to the animal populations. The most direct effect of roads on them is deadly collision with vehicles, leading to high levels of injury or death. Estimates of detectability of road-killed higher vertebrates have been determined but not for the invertebrates like butterflies, although they are frequently killed insects group on roads. This is the first comprehensive mortality census of road-killed butterflies in Nepal. The main aim of this study was to estimate the detectability of road-killed butterflies in Mahendra Highway, the busiest highway in Nepal. We established eight transects, each of 500 m long within the randomly selected forest and human settlement landscapes. Pearson’s correlation was calculated to test the link between the number of road-killed and living butterflies. All together 1000 butterfly individuals were counted throughout the study periods including road-killed and living butterflies. Among them, 364 butterflies were counted raodkilled whereas 636 butterflies were living. Forest landscape contributed higher number in both road-killed and living butterflies than human settlement landscape. Also, the number of butterflies killed on the roads were significantly correlated with number of living butterflies on the road. Our results indicate that road has the significant impact on loss of butterfly population. Also, higher the number of living butterflies more will be road mortality. The public awareness and maintaining the habitats with high forbs cover, gardening, avoid depositing asphalts, etc. in the vicinity of road can denigrate the rate of road mortality of butterflies.
