Chaitophorus populeti (Panz) is a pest of various poplar clones in Iran and many parts of the world. Oenopia conglobata (L.) is one of the most active predators that has been collected from populus trees infected with this aphid in Guilan province. To determine biology of this lady beetle in the laboratory conditions, eggs were collected from populus trees Populus caspica (Bornm) infected with the aphid C. populeti in the year 2000. In order to rear collected samples in laboratory, eggs were separately kept in Petri-dishes (10 cm) under laboratory conditions and larvale developed from the egg were daily fed with C, populeti. All of the experiments were carried out at 25°C,65% RH and LD 14:10 in the growth chamber. The results of this experiment showed the average developmental period of incubation,1-4 larval instars, prepupa and pupa as 2.36±0.08, 1.9±0.05, 1.73±0.08, 1.7±0.08,4.1±0.05, I and 4.1±0.05 days, respectively. The adult females laid eggs in batches of 7-41 on upper or lower surface ofthe leaves. The average number of daily egg laying, total eggs laid and egg laying period were 39.22±0.97, 2645.83±41.81 eggs and, 67.66±1.28 days, respectively. Average daily feeding rate for 1-4 larval instars as well as female and male adults were 19.6±0.39, 26.73±1.17, 48.33±0.75, 67.91±1.01, 44.19±0.5 and 40.92±0.71 aphid.

Oak leaf roller, Tortrix viridiana L. (Lep.: Tortricidae) is one of the important pests of oak forests. However this pest has been a quarantine pest for Mazandaran province in Caspian coast till the year 2000 which it was detected in the area. Due to serious damage inflicted by the pest to forests in northern Iran, two pheromone products (foreign product and Iranian product made by Pest and Disease Research Institute) were used to monitor oak leaf roller, Tortrix viridiana population and dispersal pattern. Pheromone traps of wing and delta designs were randomly placed in various localities (sites and heights) in Mazandaran province. For this purpose the foreign product pheromone traps were used. For comparison of foreign and Iranian pheromones, nine traps containing each product were placed in Zare forest Park and National Forest Park on 15 May 2002.Delta traps were placed within the oak tree canopy at 2 m in height and 50m minimal apart. Traps were collected on 25 May 2002 and male oak roller as well as other captured moths were counted. This pest was trapped from Sari, Neka, Beh-shahr, Galandrood, Chalus forests, Ghaem-shahr Kalar Park and Noore Forest Park. Population of the pest was higher at National Forest Park (protected Forest of Department of Environment) in Sari. Comparisons of total Iranian and foreign pheromone products did not show any significant difference between the two products (p:0.3), but both products were significantly different in terms of relative attractiveness to alternate moths (p=0.0027). In this regard, Iranian product acted more selectively to capture male oak tortrix.

In the course of study, severely infested elm trees were cut and logs divided into sections and different pest growth stages were collected. Different aspects of the biology, including egg and pupa location, larva feeding route, were studied. Host range and infestation rate were also determined on urban trees. The pest was identified as Aeolesthes sarta Solsky (Col.: Cerambycidae), The pest overwinters as larva, pupa or adult. Adults appear gradually from April to May. Life cycle of the pest lasts two years. Further to elm other host trees include, plane and willow. Overall two chemical control methods of 7 treatments including insecticidal paste (two different percentages of the compound), aluminium phosphid used as whole or half tablet as well as the control were evaluated in this study. Complete Aluminum phosphid tablets have had the highest effect on pest mortality.

For identification of termites, different castes, particularly soldier cast, were collected from different parts of Iran and were preserved in vials containing 75% ethyl alcohol. Samples were examined in laboratory and scientific names were determined. The bioclimatological study of termite fauna of Iran had been carried out based on De Martonne's climatic classification. De Martonne's climatogram is based on parameters such as aridity index (IA), mean of the minimum temperature of the coldest months (m), mean annual precipitation (P) and mean annual temperature (T). In this circumstances, localities were plotted on the climogram. Twelvs species of termites which are injurious to forest trees and shrubs are reported in this survey as the followings: Kalotermitidae, Postelecterotermes pasniensis Akhtar; Rhinotermitidae, Psammotermes rajasthanicus Roonwal & Bose and Recticulitermes lucifugus (Rossi); Hodotermitidae, Anacanthotermes ahngerianus (Jacobson) and A. vagans (Hagen); Termitidae, Microcerotermes buettikeri Chhotani & Bose, M. chhotani Ghayourfar, M. diversus Silvestri, M. gabrielis Weidner, Amitermes kharuazii Ghayourfar,A. stephensoni Harris and A. vilis (Hagen).

Black spot (Anthracnose), Marssonia iuglandis (Lib.) Magn. is one of the most important and serious diseases of walnut, which have recently occurred widely in Qazvin province. Through an extensive survey in walnut growing areas of the province, two infected sites, one in mountain (Alamout) and the other in lowland areas (Ziyabad Takestan) were located. In the course of study, sampling procedures and examining the cycle of the diseases and recording the temperature and humidity rate were regularly conducted. We also examined the results, obtained in laboratory. According to the results, the main factors affecting the infection rate are as follows: early-season occurrence of infected leaves and fruits were the most important sources of primary inoculums of the disease. When relative humidity stabled at80% for 24h, and temperature was in the range of l0- 20°C together with wind blowing, over 80% of ascospores were released. Where as, high humidity and wind during growing season are necessary for secondary infection occurrences and non-sexual spore dispersal.

Beech (Fagus orientalis Lipsky) is one of the most valuable forest tree species of lran. Live as well as felled beech trees have been subjected to attack by wood-inhabiting fungi from early times. One fungus reported for the first time in this research, is Creolophus cirrhatrzs (Pers.: Fr.) P. Karst. The fungus was collected on a beech stump in Kord-kuy beech forests of 1900 meter altitude in spring of 2001, Gorgan province. The sample stored in a solution consisted 7%o Formalin, g3Yo distillated water, 25 g.liter so4zn, and currently is housed in Alborz Research Complex in Iran. The fungus was studied based on macroscopic and microscopic characteristics, spores scaling and identified as creolophus cifthatus (Hericiaceae), from tooth fungigroup. The fungus causes white rot on beech wood.

During 1999-2001 the biology of Ocneria terebinthina Stgr, (Lep.: Lymantriidae) was studied on wild pistachio trees, in Khojir protected area in east of Tehran. According to the results, this pest over winters as larva inside the bark crevices on infected trees, under debris and dried leaves around tree bases. Activity of the over wintering larvae usually starts from late April. Pupae are formed on host leaves or in the soil. Male followed by female adults appear from mid-July. Females lay egg batches on the lower surface of leaves. The number of eggs in a single batch can be quite different and have ranged from few to more than 200 eggs. Hatched larvae feed on parenchyma around the egg batches and after molting migrate on other leaves and branches.
The 1st, 2nd and 3rd larval stages feed on parenchyma and beneath epidermis of leaves and skeletonize the leaves, but last larval stages feed on the whole leaves except for the main vein. Males and females have five and six larval stages, respectively. This insect has two generations per-year in Khojir areas. First and second generations begin from early June and late July, respectively. This insect goes to winter diapause from late September as 2nd, 3'd, and 4th larval instars. Some of natural enemies were collected as follow:
- Egg parasitoid wasp, Ooencyrtus masiiMercet. (Hym.: Encyrtidae).
- Pupa parasitoid wasp, Brachymeria intermedi Nees. (Hym.: Chalcididae)
- Pupa parasitoid midge, Exorista sp.( Dip.: Tachinidae)
- Predator bug, Rhinocoris iracundus Poda. (Het.: Reduviidae)
These natural enemies together play effective role in lessening pest population in Khojir area.
