The present article is the result of research conducted on arthropods fauna associated with poplars species in the Alborz Research Complex of Karaj, as well as in the National Botanical Garden of Iran and Khojir region in the periods 1990 - 2011. Field samplings were carried out using a Steiner trap, hand picking, net cloths around infected tree branches & trunks, as well as rearing immature stages of the pest in controlled conditions. In this study, 55 harmful arthropod species belonging to 27 families of 6 orders and over 37 beneficial arthropod species of 8 orders and 18 families were collected on 19 native and exotic poplar species. Among them, leaf-feeder insects (19 species); mites & sucking insects of sap aerial parts (28 species), and wood borer & root feeder insects (8 species) have been identified. Of the pests, 17 species were more important in terms of the severity of their attack. In terms of host range, on 19 poplar species, the identified poplar pests can be grouped as follows: 1-Pest species that are collected exclusively on one species of poplar. 2- Pest species with a wide host range. These pests found on more than one poplar species belong to 1-4 poplar taxonomic sections.

Forests and rangelands in any country are limited resources with irreplaceable economic and environmental value. Therefore, identifying and monitoring pests and diseases of trees and shrubs in forests and rangelands is important. To study and identify pests of forest trees and rangelands in Sistan and Baluchestan province, liner sampling was performed at different times during the years 2018-2022. The results showed key pest of the Jand trees is the seed-eating beetle with the scientific name of Caryedon serratus, which causes a lot of damage to the seeds of the trees. Also, the bark-eating beetle (Scolytidae) can be seen in many habitats of these trees. In addition, the Comogaster sp. was also detected in the Jands tree's habitat. Karira trees in the province are attacked by pioneer butterflies (Anaphaeis aurota), which cause significant damage to these trees. Moringa trees are also attacked by Mite Moth, which causes a lot of damage to these trees. The purpose of this study was to identify some of the most important pests of forests and rangeland in Sistan and Baluchestan province by monitoring these pests. Their outbreak can be prevented, and effective management programs can be implemented.

Hormozgan province has an area of more than five million hectares of forests and rangelands. Saharo-sindian and Irano-Toranian plants are distributed in Hormozgan province naturally. To identify and study the harmful factors of forest and rangeland pests, samplings have been visited several times during 2015-2020. These studies included pest collection, prognosis, prevention, and control, as well as identification of order, family, genus, and species. The samples of pests were identified applying the CTAB method and COI amplified. Further analyses were done, including DNA genomic extraction and using SSR markers, including LCO1490 and HCO 2198 primers. Nine species of pests were collected and identified in Hormozgan agricultural research and natural resources and education center. The important pests identified included Thiacidas postica Walker (Lepidoptera: Noctuidae), Streblote helpsi (Holloway) (Lasiocampidae: Lepidoptera), Schistocerca gregaria (Forskal) (Orthoptera: Acrididae), Hystrix leucura (Sykes) (Rodentia: Hystridae), The longhorn beetle of the family Cerambycidae, xylophagous beetle of the family Buprestidae, Nysius cymoides (Spinola) (Hemiptera: Lygaeidae), Vanessa carduie (Linnaeus) (Lepidoptera: Nymphalidae). There are three new emerging pests causing severe damage to the forests, including Streblote helpsi Holloway (Lepidoptera: Lasiocampidae), a beetle from Cerambicidae, and an un-identified bark borer on Prosopis cineraria. The purpose of this study was to identify the most important pests of forests and rangeland in Hormozgan province with emphasis on new emerging pests to manage and control these pests.
