Carpomya vesuviana Costa is one of the most important pests of Ziziphus spp. in Bushehr province. Field and laboratory studies on bionomics of this tephritid were carried out for three years (1997-1999) in Bushehr. The longevity was between 3 and 48 days in laboratory conditions. Adult longevity was from 14.6±4.2 to 25.8±6.3 days in different months. The sex ratio was 1:1. The pre-oviposition, oviposition and post-oviposition periods lasted 2 to 8, 3 to 35 and 0 to 12 days, respectively. The female lays egg after mating under fruit skin. The number of eggs/ovipunctures observed in a single fruit is generally 1 to 4 and a maximum of 8. Females laid averagely 19.1±5 eggs. Eggs-laying in most females (about 72.8%) is carried out in the first 3 to 7 days of their life. Females have higher fecundity during November and February and lower fecundity in March. The incubation period was 1-4 days and about 70.4 to 91.9 percent eggs turned out to be viable. The larval period was 6 to 22 days. Larvae had longer during December (15.5±3.6) and lived short during March (average 8.5±1.6). The maggots took 1.8 to 5 hours to prepare puparium. Pupal duration was variably different between 8-320 days. The shortest was 8 days in March-April and the longest was 320 days in September. The insect completed 8 to 10 overlapping generations each year. The shortest time for a complete cycle belonged to the flies which laid eggs in March, April and January. The longest time for a complete cycle was about 330 day which refers to the eggs laid in September-October. The over wintering and summering was a pupa within soil profile. This insect has diapose or might not have any diapose at all. Insect attack intensity was estimated between 30 and 100 percent in randomly inspected fruits. Fopius carpomyie (Hym.: Braconidae) is a larval parasitoid of C. vesuviana Costa in Bushehr province.

An investigation on Eriophyiod mites fauna was conducted in Guilan province in 2001-2002. Amrine and Manson method was applied for preparing a collection, preserving and mounting of mites on microscopic slides. In this study, one injurious species as privet rust mite (Aculus ligustri) was collected and identified from forest and ornamental privet shrubs. Morphological characteristics such as prodorsal plate, leg especially feather claw, dorsal and ventral opisthosomal micro tubercles as well as injury signs on host plants were used for identification. The privet rust mite cause browning, rusting and curling of leaves of forest and ornamental privet shrubs. Privet rust mite starts its annual activity in early spring in Guilan province. The mites population increases rapidly during spring season, and vast number of vagrant mites are observed on each leaf surface. Leaves might be tightly rolled in a way that infested twig appears to be leafless. In late spring, because of increasing temperature, mites migrate to aestival positions under privet bud scales.

Juniper is one of the most important trees in Iran which are widly distributed in different parts include Qazvin Province.
The main juniper forests of province are located in Rudbar Alamut, Rudbar shahrestan, Tarom-e-Sofla, Abyek and the prevailing species in these area is J. excelsa subsp. polycarpos.
In the course of study, samples of soil and roots were taken from juniper forests. The soil was mixed, and washed in laboratory using De Grisse (1969) method. The nematodes were extracted, fixed and transferred to glycerin. Infected roots were colored and studied in two ways: colored with and without lacto phenol foshin Acid.
In this study 11 nematode species belonging to 8 genera of Tylenchida order were identified.
These include:
1- Boleodous thylactus 2- Criconema mutabile
3- Criconemella antipolitana 4- Criconemella xenoplax
4- Cacoparus pestis 5-Helicotylenchus microcephalus
6- Helicotylenchus pseudodigonicus 7-Meloidogyne javanica
8- Pratylenchus neglectus 9-Prathylenchus thoreni
10- Tylenchorynchus latus

In this study, which was carried out in Al-Bajie area, durability and mechanical properties of Eucalyptus wood (E. camaldulensis Dehnh.) were evaluated in treated and untreated plots against rain bow fungus, (Trametes versicolor) using Koleshale methods described in Din 52176, and B. S. 838 and termite damage based on IRG/WP-1290 method.
Samples consisted wood pieces of 1.5×2.5×5 and 2×2×6 Cm for fungus effect and 2.5×2.5×2.5 and 8×8×30 Cm for termite damage. Celcure and Creosote were applied against termites.
Beech wood (F. orientalis) as control were damaged completely by termites and samples of E. camaldulensis which have been placed for 7 years, subjected to 30% damage, while samples treated by Celcure and Creosote were unaffected.

Empoasca decedens Paoli, is one of the most important poplar pests in Charmahal and Bakhtiary Province. Feeding of the pest cause discoloration, rolling, wilting, and ultimate dryness of the host leaves. This survey was carried out in nursery of poplar colons in Boldajee station in the year 2000. During the experiment it was shown that P. alba, P .d. marilandica, P. e. gelrica, P. e .triplo, P. e. vernirubensis, P. n. betulifolia are infested very severely by the pest. In other to determine host preference, sixteen trees of each colons were selected in Aug, 2000 samples consisted of four leaves from each tree taken at the breast height for every geographical direction. On each leaf the density of leaf hoppers per cm2 were determined. The data were analyzed in randomized complete design. The comparison of means was conducted by Duncan multiple range test.
The results indicated that P .d. marilandica and P. alba are highly infested with 2.84±0.11, 2.37±0.16 insect per leaf area unit respectively. These were significantly different from other colons, including P. e. triplo, P. e. gelrica, P. e. vernirubensis and P. n. betulifolia with 1.24±0.13, 1.2±0.8, 1.05±0.14, and 0.66+0.01 insect per leaf, respectively. This is the first report of the insect for the country and poplar is recorded as a new host for the world.

Arasbaran forests are located in East Azarbaijan and account as one of the most important forests of north western of Iran. Due to the impacts Khazari, Ghafghazi and Mediteranean climates, this area has wide variety of biological societies. In reach plant coverage of Arasbaran forests Horn-bean and Oak trees (Quercus petraea and Q. macranthera) are dominant species respectively.
The Oak weevil, Balaninus glandium Marsh. is one of the most important key pests (about 40% damage) of Oak trees in Arasbaran forests. The pest feeding inside the Oak fruit, cause destruction of seeds. During the biological study of the pest in Arasbaran we found some of it's natural enemies. In the course of survey of the natural enemies of the pest, a larval parasitoid wasp of Ichneumonidae familly was found and later identified as Scambus planatus (Hartig). The wasp has identified by Dr. E.Diller in German Museum of natural history and is reported here for the first time from Iran. The parasitoid wasp overwinters as adult and has a single generation in Arasbaran area. The rate of parasitism was estimated between 0.53% to 10% (average 3.93%) on its host.
