The tachinid fly, Pales murina Mes. is a larval parasitoid of jujubetree (Ziziphus sp.) defoliator, Thiacidas posticaWalker (Lep.: Noctuidae) in south of Iran. The parasitoid eggs are laid on lower surface of fresh leaves. Third and fourth instars of the host larvae are parasitic after ingesting the parasite eggs. The study was conducted to determine the affecting factors on orientation, seeking and finding the host by the parasitoid using a 4-wats olfactrometer designed by authors. The first experiment was conducted in a completely randomized design with four treatments and 10 replications each using 10 gravid females. The treatments consisted of 1- individual larva feeding on leaves, 2- individual larvae, 3- shredded leaves and 4- whole leaf sample. Results showed a significant difference between numbers of females attracted to the treatments of larvae feeding on leaves and other treatments. Although no significant difference was found between the two treatments of shredded leaves and individual larvae, they attracted more flies than the treatment of whole leaves. The second experiment was conducted in four replicates and treatments including the above treatments except for the replacing a single larvae with feces instead of larvae feeding on leaves. The results of this experiment showed a significant difference between the number of females attracted to the treatment of larvae with feces and the other treatments. However, no significant difference was observed between the single larvae and whole leaves treatments. It can be concluded that the parasitoid is attracted to host tree and pest larvae by chemical volatiles emanated from damaged leaves.

Poplar leaf aphid Chaitophorus leucomelas is one of the most important pests of poplar plantations in Iran. Economic losses from this pest may be caused through sucking plant sap and excretion of honeydew as well as disruption of photosynthesis process. In view of the high densities of the pest on poplar trees, an experiment was carried out to investigate growth parameters and life table of the insect on Populus nigra 56/53 in growth chamber at 22±1 ºC, 50-60% RH with a 16L: 8D photoperiod. Some population growth parameters of poplar leaf aphid, such as net reproductive rate (R0), intrinsic rate of natural increase (rm) and finite rate of increase (l) were 12.12 nymphs/female, 0.211 nymphs/female/days and 1.24 days, respectively. These results somehow indicated a relatively high reproductive potential of the C. leucomelas on P. nigra 56/53.

Nowadays as a result of low amount of harvestable forest products, low areas of wood plantation and increasing need of wood industry to wood and cellulose products, importing wood and its different products has become one of the unavoidable necessities in order to protect forests and answer the need of wood industries. As different species of important non-native pests can inter the country with wooden products and cause severe damage, preparing and introducing scientific and technical quarantine rule for importing plants and regarding them by wood importers can play an important role in preventing the pests to inter the country. This fact can not be done without careful study and research, something that is now perfectly done in European countries, North America, China, Japan, South Korea, Australia, New Zealand and some other countries. The current quarantine rules for importing wood and wooden products in Iran are mainly planed based on international standards and results of the researches carried out in other countries. In order to facilitate importing wood and wooden products to the country, some revisions and corrections have to be done in the rules based on native researches and studies. Determination of research priorities, forming skilled scientific research groups including native professionals and researchers and trying to perform basic as well as applied researches to clear the dark points and answering the main questions and solving problems of quarantine rules of importation can be done primarily to prepare a proper field to write and compile scientific and technical rules. Such affairs are among the duties that should be taken care of by responsible authorities such as Research Institute of Forests and Rangelands of Iran as well as Iranian Research Institute of Plant Protection. It is clear that these affaires will end to facilitate importation and also protect the basic principals of plant quarantine rules. In this article after a review of wood resources, product capacity of related industries and need of the country to wood importation, role of wood and wooden products in dispersing quarantine pests in the importer country will be considered; then after emphasis on importance of observing and regarding plant quarantine rules in importing wood products, problems and limits of the current rules have been studied. Necessity of revision and correction of the current rules based on native researches and knowledge have been discussed and in the end a list of some priorities in native research that should be done to improve quarantine rules of wood and its products have been mentioned that their results affect and revise plant quarantine rules and facilitate importation of wood and its products as well s protection of plants and plants' health care.

To determine extant infected Persian oak forests to parasitic plant, Loranthus europaeus, an area of 700 ha was selected in south of Manesht mountain in north of Ilam province. In order to make an inventory of the healthy as well as infected trees, a two phase sampling procedure with continuous line was applied. First, the oak species ratio was estimated and then the ratio of infected oak trees was determined. Results showed that the total number of trees were 154.47 per ha with 80.2% of them belong to oak species. 25% of oak trees were infected and the rest were healthy. 32.1% of oak trees showed dieback. All of the infected trees by mistletoe showed dieback of branches. It can be concluded that mistletoe activity was affective on dieback of oak trees. This study also showed that the highest rate of mistletoe infection was in mid part of tree crown and the lowest rate was in upper and lower parts.

Two pests species, Ocneria terebinthina Stgr. and Thaumetopoea solitaria Frever, are among the most important pests of wild pistachio trees. The predator bug, Rhynocoris iracundus Poda was collected from Khojir protected area while it was feeding on larvae of both mentioned pests. Mature as well as immature stages of this predator of Reduviidae family voraciously feed on the pest larvae. In order to study on biological characteristics of this predator, collected specimens were breeded on larvae of Ephestia kuehniella and hen liver in laboratory. According to this study each female adult lays 50 to 85 eggs as cluster (X±SD=73.3±14.4). Incubation period is 10.3±2.2 days. This insect has 6 nymphal instars which last about 2 months. Longevity of adults is varied and takes 13 to 37 (24.1±10) days. As the insect does not have obligatory diapaus so it is possible to breed that throughout the year in proper condition. The nymphs of this predator have cannibalism and even when enough food is available, they feed on eachother. Some female adults feed on males while mating.

A detailed knowledge of species diversity of pests of each host plant and the seasonal occurrence of them is essential for an integrated pest management program. To provide such basic information, a two-year survey was conducted for the first time on injurious mites associated with coniferous and broad leaf trees and shrubs in forest parks in and surrounding of Mashhad. As a result, 14 mite species belonging to families Tetranychidae and Tenuipalpidae were collected and determined. Among them,9 species are reported for the first time from Razavi Khorasan province including 3 new records for Iranian fauna. The species, Oligonychus ununguis (Jacobi) and Tetranychus turkestani (U.& N.) were found in higher numbers and had more hosts. This article presents information on morphological characteristics as well as habits of collected mites on some common trees and bushes in woodland areas in suburbs of Mashhad city.

The parasitoid Gelis caudator of the subfamily Cryptinae (family Ichneumonidae) is here recorded for the first time from Iran. The adult specimens of G. caudator were collected under the bark of host tree, Juniperus excelsa, where the overwintering larvae and pupae of the pest Argyresthis sp. (Lepidoptera, Yponomeutidae) were occurred. Some specimens emerged from the pupae of the host.
