Currently, over one million cubic meter of wood is imported from Russia to supply local needs for wood material which is 2 milion cubic meters per year. However introduction of exotic pathogens poses major threats due to lack of proper monitoring and effective quarantine policies and procedures. In this regard, Northern harbours (Anzali and Astara in Guilan, Noshahr and Amirabad in Mazandaran) were visited and imported woods were sampled. As a result of this survey 22 genera and 33 species of Ascomycetes, Anamorphic fung, Basidiomycetes and Myxomycetes were identified. The identified fungi are as follows: Acremonium cf. alternatum Link, Acrostalagmus luteoalbus (Link) Zare, W. Gams & Schroers , Alternaria cicina*E.G. Simmons 1994, Aspergillus caespitosus* Raper, K.B.; Thom, C., 1944, A. flavus Link, A. niger Tieghem, , A. terreus Thom, A. unguis Dodge, A.vitis Novobranova Chaetomium indicum* Corda, A.C.J., 1840, Cladosporium sp., Clonostachys rosea Schroers; Samuels; Seifert; Gams, W., Epicoccum purpurascens Ehrenberg. , Eurotium amstelodami Mangin, Fusarium cf. concolor *Reinking Fusarium oxysporum Schltdl, Geosmithia spp*, Graphium spp., Hyphodontia sp*., Melanospora sp*.,Nattrassia mangiferae (Syd. & P.

Oak trees are among the most important hosts of cynipidae gall wasps. In this investigation alternation of generations and hosts in oak gall wasps of the genus Andricus were studied on two oak species inLorestan province in 2003-2005. There are two oak species, Q. infectoria and Q. brantii with different dispersal patterns in Lorestan province. Q. brantii belong to Cerris section with wide dispersion in this province and Q. infectoria belong to Quercus section which occurs only in Ghalaii region. To determine dispersal pattern of oak gall wasps and their relationship with oaks species, sampling procedures were conducted for 3 years on the galls. Overall, 14 gall wasps species of Andricus genus were collected on two oak species; Quercus infectoria and Q. brantii in Lorestan province. Results of this investigation revealed the occurrence of host-alternation in four species, Andricus lucidus, A. cecconi, A. grossulariaeand A. multiplicatus in Lorestan province.

Camarotoscena fulgidipennis Loginova is considered as an important sucking pest of poplars in Iran. During 1991-1992, damage rate of C. fulgidipennis was evaluated on 15 native & exotic poplar species and clones in Alborz Research Center of Karaj Experimental species include: Populus trichocarpa Torr., Populus simonii Carr., Populus ciliata Wall, Populus nigra L.and Populus alba L.. A randomized complete block design with 3 replications was applied. Each block included 25 seedlings. Buffers were ignored and 6 seedlings were examined for psyllid damage at 15 day intervals starting in mid-June until late September. In order to sample, damage of leaves percentage were estimated on seedling. A numbering method was applied (0-4) to measure damage rate. Data were analyzed by MSTAT- C software and Duncan test (α=1%) was applied to compare the means. Based on two years results, there was significant difference (α=1%) between poplar species and clones. In 1991, of all poplar clones, P. nigra 42.78, P. nigra 47.3 and P. nigra 56.33followed by P. nigra 56.32 and P. nigra 42.53 showed high damage. In 1992, mentioned clones and P. trichocarpa placedin one group had the highest damage. Based on the results, there were no damage onP. alba, P. ciliata, as well as the other clones of P. nigra.

Country pastures, are considered as major sources of sustained forage production and their preservation, restoration and development, is very important. Therefore, in recent years through carrying out range projects, their management and protection across the country has been assigned to the stakeholders. In this regard, since the year 1993, pasture lands in khorasan Razavi province has been partly assigned. Accordingly, the total goal of this study is to determine the economic scale of pasture considering the number of livestock productivity and the scale of the land and also assessing the technical and economic factors affecting the productivity of pastures. To this end, of the 221 range management project in Khorasan Razavi province, 38 projects of 11 cities have been selected using a two-stage cluster sampling. Questionnaires were completed in the year 2006. Then, the total productivity of the affecting factors was calculated using the Tornquist-theil Index and the optimal area of Range Management Projects was calculated taking into account the number of livestock productivity and the scale of the land. The Results of productivity model showed the optimum land area as 267 hectares for any single stakeholder. Considering the average share of each beneficiary in Range Management Projects of Khorasan which is currently 253 hectares, the size of pasture lands in most Range Management plans, are economically suboptimal. The calculated optimal number of livestock units also is 3437 unit. Since the average number of livestock sampled in Range Management units is 4359, obviously the present number of livestock units in Range Management Projects, is over the desirable number in most projects; so, reducing the number of livestock units in these projects will eventually increase pasture productivity.

This research was conducted on the survival, growth, biomass and vitality status of Arizona cypress (Cupressus arizonica var. arizonica Green.), Medite cypress(C. sempervirens var. horizantalis), Brutia pine (Pinus brutia Ten.) and Aleppo pine (P. halepensis Mill.) seedlings subjected to weeding as well as various combinations of organic matter and leaf litter use at Koloudeh nursery, Amol city (north of Iran).). Seeds were planted in plastic pots in a randomized block design with four replications. Two weeding treatments of 10-day (W1) and 20-day (W2) intervals and different treatments include soil 1) control soil 2) control soil+ manure (1:1), 3) control soil + decomposed litter (1:1), 4) control soil + manure + decomposed litter (1:1:1) were applied. The results obtained for each species seedlings following first growing season indicated better response of W1 compare to W2 for most of the characteristics include growth, biomass, vitality and performance. C. sempervirens in no. four soil treatment with 10 day weeding interval, showed the optimal rate of all studies traits. Decreased competition, increased light, nutrient availability could be attributed to shorter weeding interval and successful seedling establishment. Therefore, weed control applied at shorter interval (10-day) during the first growing year combined with fertile soil is recommended.

Moringa peregrina Fiori was first cited in Iranian flora in 1993 by late Dr. Javanshir. Its presence has also been reported in Persian Gulf states, Saudi Arabia and occupied Palestine. Moringa is a tree species which grows over rough train of Makran and Bashagerd mount ranges respectively in Baloochestan and Hormozgan Provinces. Major maturely distributed areas of the species include Bashagerd mount in Nikshahr through south Jazmorian. The species does have strange tolerance against lack of water. In a way, it can afford survive for years in the absence of a drop of rain. Plants root system as well as the specific bed rocks of the growing areas are the most important factors affecting the Moringa's survival. Based on the two years sampling and research results, there was not any specific insect, fungi or bacteria associated with Moringa tree. Sampling procedures conducted on the different parts of the plant collected in Sistan and Baloochestan and Hormozgan Provinces revealed only a single species of scale insect from Chanoof area. The species was identified as Parlatoria crypta of Diaspididae family. This is a polyphagaus insect with a wide range of hosts in southern Iran.

Thrips are considered as the minor pests in the pistachio orchards in Iran. However their economic importance is different at various pistachio plantations of the country. In present investigation the population fluctuations and damage of Liothrips austriacus (Karney) on cultivated (Pistacia vera linnaeus) and wild-pistachio trees (Pistacia atlantica, subspecies P. mutica (Fisher and C. A. Meyer) were surveyed in Rafsanjan, southern part of Iran. It was found that the population fluctuations of this insect is different on both examined host plants. Population density of L. austriacus began to increase from early April and reached to its peak in July and then declined thereafter gradually. This species disappeared on aerial parts of pistachio trees immediately after harvest and prior to leaves fall. However, on wild pistachio trees, the population density reached to peak in June and declined to low density conditions. The developmental period of the insect on wild pistachio trees in mountainous areas was clearly shorter than that of cultivated trees in plane areas. The present work showed that the thrips larvae cause damage on fruits due to feeding on pericarp. Liothrips austriacus causes brown spots on fruits’ hull, then injured fruits becomes dry and irregular cracks appear on fruits' pericarp. No symptoms of thrips injury were found on aerial parts of the wild pistachio trees. In the meantime, thrips-infected fruits were furthere examined for aflatoxin contamination. As, L. austriacus is commonly active on pistachio fruits, the term "pistachio fruit thrips" have been applied to describe the pest in the literature.

Recently, showy mistletoe (Loranthus europaeus) has been a major menace in the fragile ecosystems of oak forests in western part of the country. Loranthus has done symbiosis mainly with oak trees and it is not troublesome by itself, but a massive population of Loranthus species in the same tree can cause sever damage and death on the host trees. Ilam province forests occur in different climates and stands conditions and provide various ecological potentialities based on their locations and geographical situations. The present work tries to determine the ratio of Loranthus presence in Ilam province forest stands (Meyan tang) and to evaluate the present status of the tree stands. In this regard, taking into account topographic conditions and vegetation changes along with elevation increase, the randomized stochastic bandy method was used. To perform quantitative and qualitative study, twenty type bands were calculated. The distance of type bands with regard to their number was selected as 100 m. To carry down bands, a statistical network was designed in a way that the first band was randomly selected following 50 m pass and the next band was determined 100m apart. Results indicated that average number of parasitic plant in the sample in the directions of north compare to south and east differed significantly (five percent level). But average of this parameter between aspects of east and west did not show any significant difference. Oak and Crataegus were the most and least infected species respectively. Over 56% of the samples were infected and relative number of parasite occurrence was 2.75 per infected tree. Results of one-way analysis of variance didn’t show any significant correlation between average number of parasites on the samples and different slopes.
