Poplar leaf aphid is considered as a sucking pest of poplar in Iran. The aphid reported from most parts of the country cause damage in some years. As, host plant species and clones may have effects on feeding behavior of insect pests; growth and developmental parameters of the aphid were studied on eleven poplar clones belonging to Populus euramericana, P. deltoids and P. nigra species. Poplar cuts of 10 cm length and one cm diameter from each clone placed in rearing cages containing wet cotton pieces. Two adult aphids were released on each clip cage closed to poplar leaves. After 24 hours, five new borne nymphs were placed on each cut and the rest were removed. Then number of living nymphs and immature aphids were counted and recorded daily till their maturity. On the first nymph became matured, the other nymphs were deleted and the number of nymphs were daily counted. In order to evaluate the longevity of aphids, they were retained till they died. The experiment repeated 8 times and was carried out in a controlled chamber at 24±1º C, 50-60% RH and photoperiod of 12:12 (L: D). Based on the collected data, growth and developmental parameters of the aphids include pre-adult and post adult periods, longevity and fecundity were calculated on every tested clone. Aphid development time on P. euramericana 242 and P. deltoides missoriensis were longer than the other clones, while this period was the shortest on P. deltoids 72/51. Number of nymphs per female on P. deltoides 72/51 and P. deltoides missorensis were 98 and 49 respectively.

In the course of the survey of insect fauna associated with forests and rangelands of Iran (1993-2003), we started the investigation of Scarabaeid beetles fauna. Specimens were collected by light trap, banana trap, pitfall trap, sweep net or caught directly by hand. Following transfer of insect specimens to the respective laboratory, preliminary identifications were carried out using diagnostic keys as well as close cooperation of Dr. Oliver Montreuil of Muséum national d' histoire natural (Paris) who determined or confirmed the identifications. All specimens together with relevant localities are currently maintained in Arthropod Museum of Research Institute of Forests & Rangelands. A total of 31 species belonging to 10 families identified. We expect to have many more data in the future.

Although the point source pollutants have been somehow controlled in the word, major improvements in alleviating pollutants effluents and their flows to water resources are still lacking. ZarivarLake is one of the exceptional tourist attraction points in the west of Iran which has been placed on the wetlands list of World Environment Organization. Farmers use the water of the lake as an irrigation source.
This research contains 2 distinct steps: Field runoff sampling and analyzing for: BOD5, total Phosphorous, total Nitrogen and total suspended solids and statistical analysis of the recorded data. Based on this study the basin has four major land use types: forest, pasture, farming and urban. The run off coefficient was calculated for each land use type by rational method and then confirmed by curve number method. The project had four treatments and three replications. The concentration and the value of pollutants for any land use type were compared by analysis of variance and comparing the means. Then the land uses were sorted descendingly based on the pollutants load they produce, and ultimately the annual pollutant load flowing into the lake was estimated. The results indicated significant difference between land uses, with the farming operations as the most pollutant type.

Decline and dieback is the most important diseases of eucalypt trees in Khuzestan province. In order to determine disease resistance of existing eucalyptus, four species and one provenance include Eucalyptus camaldulensis, E. camalulensis 9616, E. sargentii, E. microtheca and E. gillii, were evaluated using two different methods of “detached stems technique” and “seedling infection”. In detached stems technique, 8 branches (1 cm.diameter and 25 cm. length) from each species were selected and following surface sterilization with ethanol, five mm diameter bark disks were removed and inoculated centrally with a disk of agar carrying mycelium of highly virulent fungus obtained from diseased E. sargentii in Dobb-Hardan of Ahwaz. In the infection seedling method, 8 seedlings from each cited species were selected and wound-inoculated on stems. The rest procedures were the same as the previous technique. Each non-inoculated control plant received a P.D.A. disk. Wounds of two tests were covered with parafilm and sealed with adhesive tape. Eight replicate branches of each treatment were incubated at 35 ± 1 °C with R.H. 80 ± 5. At the end of two weeks of incubation period, the bark was removed and lesions on the cambium were examined, transferred to paper and their sizes were measured and analyzed.
Of the Eucalyptus trees evaluated in this study, E. sargentii and E. camaldulensis showed higher resistance than E. microtheca, E. gillii and E. camaldulensis 9616 in both methods mentioned. According to the results, resistance reaction of all species to N. mangiferae were the same in both methods. The most resistant species was E. sargentii while, E. camaldulensis 9616 was very susceptible species.

In the course of a survey carried out on oak gall wasps (Cynipidae: Cynipini), during 2003-2005 in West-Azarbaijan province, three new galls were collected from Quercus infectoria. The gall inducing wasps were identified based on gall shapes. The gallwasps are identified as follows:
1- Andricus curvator Hartig, 1840 (sexual generation)
Date and location of the gall collection: June 2004- Zamziran
2- Cynips cornifex Hartig, 1843 (asexual generation)
Date and location of the gall collection: August 2004- Nalas
3- Neuroterus albipes (Schenck, 1863) (= N. laeviusculus Schenck, 1863), asexual generation
Date and location of the gall collection: October 2004- Ghabre Hossein
Based on studies, carried out on the Iranian oak gallwasp project, galls of three mentioned wasps were found only on Q. infectoria and only in oak forests of West-Azarbaijan province. All the three species are new for the fauna of Iran.

In the course of study of Thysanoptera fauna of forests and rangelands in Khuzestan province, a specimen collected on Teucrium oliverianum Gingins and Stipa capensis Thunb. on March 2002 in the Shahion area of Dezful (500m height) was identified and confirmed as Rhipidothrips unicolor by Dr. R. Zur Strassen. Formerly, 4 species in this genus have been reported from Iran and this is a new record for the fauna of Iran. Rhipidothrips unicolor can be distinguished by antennal segment II dark brown, Setae on posterior margin of pronotum short, at the most up to 25 µm long, often only 2 pairs of these setae are present, Lower vein of fore wing with mostly 11–20 setae, or the insects are brachypterous. Apices of middle and hind tibiae are dark, tarsi likewise dark. Internal body pigment is yellow to orange colored. Fore wing brownish-gray, setae on veins grayish brown. Setae on abdominal tergum IX brownish yellow, sometimes even pale yellow. Antennal segment III 46–57 µm long, 1.2 to 1.4 times as long as segment IV which is 39–46 µm long.

Chestnut forests of Iran occur only in Guilan province as the following areas; shaft (Visrood-Taleghan-Lepundan), Talesh (Shafarood) and Fuman (Ghaleh roodkhan). These areas have been subject to chestnut blight in recent years. Protection of chestnut stands is accounted as one of the most important research goals in Iranian forests research. In this study, infected sites were visited in Visrood and Shafarood forests. All infected trees demonstrated symptoms of canker and blight on trunk and branches. Some branches were dried and trunk bark was opened. A number of orange dots occurred around opened spots. These symptoms are good signs for chestnut blight recognition. Sampling procedures was carried out on branches and main trunks. In laboratory samples were examined by microscopic observation. Perithecia, asci and ascospores were observed under microscope. In order to soften the plant tissue colored dots, samples were boiled in KOH 10% for 3 minutes. In this stage, preparations were bright and clear. Then all of preparations were fixated. On examining the preparations, many ascocarps were observed into stromata. Every ascocarp had a tall neck. Perithecia 300-400 micrometer in diameter, embedded in stroma, dark brown to black, membranous, globose to flask shaped, with slender black necks up to 600 micrometer long. Asci oblong elliptic to subclavate, 30-60 X 7-9 micrometer. Ascospores hyaline, two-celled, sometimes constricted at the septum, ellipsoid, 7-11 X 3.5-5 micrometer, with a gelatinous envelope. Based on the scientific references (Roane, 1986) and (Falahati, 1991), this fungus was determined as Cryphonectria parasitica (Murr ) Barr. This is the first report of the fungus from Iran.

In October 2005, specimens of powdery mildew were collected on oak trees from West Azarbaijan and Kordestan provinces forests. There are three species of oak trees in these forests as follows, Quercus brantii Lindl. , Q. infectoria Oliv. and Q. libani Oliv. , but symptoms of disease had seen only on Q. infectoria leaves. During the survey, two species of fungi causing powdery mildew were identified as follows:
1- Erysiphe alphitoides var. alphitoides
Mycelium on leaves, amphigenous, mostly on upper surfaces, forming patches or effused, grayish white, conidia ellipsoid-ovoid to doliform, (24-) 27-33 (-36) × 12-22.5 μm, cleistothecia subgregarious to gregarious, dark brown, (72-) 88-132 (-152) μm, appendages (4-) 6-15 (-25) in number, (60-) 80-140 (-180) μm in diameter, equatorial, hyaline, aseptate, apex 3-6 times dichotomously branched, branches close and regular, tips of the ultimate branches recurved when mature, asci 3-9 (-12) in number, sessile or with short stalks, (45-) 56-64 (-72) × (32-) 36-48 μm, ascospores (2-) 3-7 (-8) in each ascus, ellipsoid to ovoid, (15-) 18-21 (-25.5) × 9-15 μm.
These characters with slight differences in number of asci and ascospores were the same as that Braun (1987) had said for Microsphaera alphitoides var. alphitoides, however, in the studied specimens, asci and ascospores number was 3-12 and 2-8 respectively, but the above mentioned number in the Braun key (1987) are 5-16 and (4-)6-8 . According to the recent changes-based on phylogenic surveys-on the taxonomy of some Erysiphaceae proposed by Braun and Takamatsu (2000), this species is accepted as Erysiphe alphitoides var. alphitoides.
Specimens examined: on Quercus infectoria, West Azarbaijan, between Piranshahr and Sardasht, Qabr Hossein, 1440m, 4 October, 2005, Tavanaei & Zargaran, (315F1001). Kordestan, between Baneh and Mahabad, Kanisoor village, 1550m, 3 October, 2005, Tavanaei, (315F1003). Kordestan, between Saqqez and Baneh, near the Gemareh leng village, 1480m, 2 October, 2005, Tavanaei & Fatehi, (315F1006).
2- Phyllactinia guttata (Wallr. : Fr.) Lev.
Mycelium forming on lower surfaces of leaves, spots yellowish white, conidia clavate to fusiform, 44-64 (-76) × (12-) 16-24 μm, cleistothecia subgregarious, mostly not mature, mature ascocarps (180-) 220-260 μm in diameter, peridium cells irregularly polygonal, appendages 4-9, equatorial, acicular, with basal swelling, bulbous base 36-60 μm in diameter, appendages lenth 140-360 μm, asci with short or long stalks, 13-19 in each ascocarps, 68-100 × 28-40 μm , 2 spored, ascospores ellipsoid to ovoid, 28-40 × 16-22 μm in diameter.
The mentioned attributes were according completely to characters of Phyllactinia guttata that described by Braun (1987).
Based on available literatures, the fungus Phyllactinia guttata don’t reported on Q. infectoria previously in all over the world, thus, Q. infectoria is reported as a Matrix novafor mentioned fungus.
Specimens examined: on Quercus infectoria, Kordestan, near the Baneh, 1450m, 3 October, 2005, Tavanaei, (315F1101).
