Population growth parameters of Tetranychus urticae Koch on four bean varieties including Talash (Colorado bean), Sadaf (Navy bean), Goli (Kidney bean) and Parastoo (Black-eye bean) were investigated in laboratory conditions at 25 ± 1°C, 60 ± 5% RH and a photoperiod of 16: 8 (L: D) h. In this experiment, one-day old eggs of T. urticae were selected and reared in growth chamber until the death of the last female mite, and the survival rate and female progeny of the mite were measured. Net reproduction rate (R0) on four bean varieties, was 8.822, 3.622, 4.908 and 2.043, intrinsic rate of increase (rm) was 0.142, 0.079, 0.095 and 0.038, and finite rate of increase (λ) was 1.152, 1.082, 1.099 and 1.039, respectively. Mean generation time (T) was determined 15.381, 16.283, 16.715 and 18.308 and doubling time (DT) was 4.901, 8.787, 7.292 and 18.125 days, respectively. The results indicated that the rate of population growth of T. urticae on Talash variety was more than other varieties. The rates of population parameters on Parastoo variety were the least.

The life history of an acarid mite, Tyrophagus putrescentiae (Schrank), on Fusarium graminearum Clade was investigated at 25 ± 1°C, 60 ± 5% RH and a photoperiod of 16: 8 (L: D) h. Incubation period for egg hatch, larval and nymphal periods and adult longevity were 2.22 ± 0.06, 3.46 ± 0.12, 4.84 ± 0.16 and 10.05 ± 0.9 days, respectively. The average life span of males and females were 22.22 ± 1.21 and 19.08 ± 1.37 days respectively. Pre-oviposition, oviposition and post-oviposition periods were 2.22, 5.77 and 1.4 days respectively. Gross and net fecundity rates were obtained 76.2 and 23 eggs per female per generation respectively. Net reproduction rate was 12.5 female eggs per female per generation, and average daily oviposition rate was 5.7 eggs. The intrinsic and finite rates of population increase were 0.15 and 1.16 day-1 respectively. The mean generation time (T) and the mean doubling time (DT) were 16.74 and 4.59 days respectively. The population mainly (78%) consisted of eggs and larvae, and nymphs and adults represented only 22% of the population.

A study was carried out to determine the suitable spraying time for phosalone against alfalfa weevil, Hypera postica (Gyllenhal) (Col.: Curculionidae), with the least adverse effects on its major parasitoid, Bathyplectes curculionis (Thomson) (Hym.: Ichneumonidae). Plots of 10 m2 were sprayed with phosalone (35%) at 3.0 kg/ha, using a knapsack sprayer. The residues of phosalone in parasitoid cocoon and alfalfa foliage were measured at different time intervals after treatment using high performance liquid chromatography. Residues of phosalone on B. curculionis cocoons treated by dipping method were 0.751, 0.466, 0.245, 0.115, 0.075, 0.044 and 0.019 µg/cocoon in 2 hours, 1, 3, 7, 14, 22 and 30 days after treatment, respectively. Results of this experiment revealed that there was no penetration of the insecticide into the cocoon. In fresh foliage, the residues of phosalone were 74.066 ï± 6.9, 47.319 ï± 2.1, 16.345 ï± 1.99 and 3.743 ï± 0.33 mg/kg at 2, 4, 7 and 14 days after spraying, respectively. The residue level on foliage at day 7 is critical and this must be considered as the least interval time between the application of the phosalone and the peak of parasitoid population.

In the current study, the information on occurrence, distribution and host aphid-plant associations for the species of Praon Haliday in Iran are presented. Eight species of Praon were found in the areas under study, which include four previously reported species, viz. Praon absinthi Bignell, Praon barbatum Mackauer, Praon exsoletum (Nees) and Praon volucre (Haliday), and four new records, Praon orpheusi Kavallieratos, Athanassiou & TomanoviÄ, Praon rosaecola Starý, Praon abjectum (Haliday) and Praon yomenae Takada, of which P. volucre was the most common species. The presence of P. yomenae as a parasitoid of Uroleucon aphids, instead of Praon dorsale (Haliday), which does not occur in Iran, is documented. A key for identification of the Praon species occurring in Iran is presented.

Age-specific life table parameters of Aphis gossypii Glover (Homoptera: Aphididae), one of the major pests of cotton in the Gorgan region, were determined on Gossypium hirsutum L. at different periods during 2002 and 2003 growing seasons. Population projection matrices were used to calculate aphid population elasticity and sensitivities to the changes of aphid survival and fecundity rates. A. gossypii attained its optimum growth and reproduction rates at early season (July). At this condition, the net reproductive rate (17.16 female/female), intrinsic rate of increase (0.349 female/female/time) and finite rate of increase (1.42) were the largest, while population doubling time (1.96 days) was the smallest. At mid and late seasons (August and September) the intrinsic rates of increase were 0.257 and 0.208, respectively. The lowest intrinsic rate of increase (0.073) was observed during a short period in early August. Survival curves of the aphid population were near to Deevyâs type III. The elasticity and sensitivity of nymph survival rates were higher than the adult fecundity rates and decreased relative to the age increasing.

The genus Euphorbia L. (Euphorbiales: Euphorbiaceae) typically have a poisonous white sap in all plant parts. Weedy spurge, Euphorbia boissieriana Prokh., is a toxic deep-rooted herbaceous and perennial weed that is native to the north west of Iran. The biology of spurge clear-wing moth Chamaesphecia schizoceriformis Kolenati as a biocontrol agent of E. boissieriana was studied at field and laboratory conditions (23 ± 2ºC, 60-70% RH, 14L: 10D h) during 2002-2004 in Orumieh region. A field and laboratory observation showed that spurge clear-wing moth was a univoltine species feeding on a single host plant, E. boissieriana. The flight period extended from mid June to the beginning of August. Females, after mating, laid their eggs singly on vegetative stems, mostly on the upper part of the older plants. Females laid an average of 205 ± 29 eggs and potential fecundity was 223 ± 27. The larvae of C. schizoceriformis hatched after 7.90 ± 0.23 days at mean daily temperature of 24.2 ºC. The young larvae penetrate into the stem a few centimetres above the ground and then move into the pith and down into the root. Based on the measurements of head capsules, this moth has seven larval instars and reaches the 5th or 6th instar before winter. In the spring, the larvae mined up to the stem base and prepared an emergence hole a few centimetres above the ground and then pupated within the stem. At mean daily temperature of 20.2 ºC, the pupal period was 13.43 ± 0.27 days. Study on parasitoids of C. schizoceriformis revealed that the larvae and pupa of this moth were parasitized by Villa sesivora Greathead & Karimpour (Dip.: Bombyliidae), Bithia glirina (Rondani) (Dip.: Tachinidae) and Phaenolobus saltans (Gravenhorst) (Hym.: Ichneumonidae) in Orumieh region.

Since the use of insect cell lines for producing bio-pesticides and recombinant proteins is increasing, the establishment of new cell lines will help to enrich this industry. Therefore, several primary cultures were initiated from embryonic tissues of silkworm, Bombyx mori L. using both enzymatic and mechanical methods. The cultures were incubated in TC-100 medium supplemented with 10 and 20% concentrations of fetal bovine serum (FBS) at 27ºC. Among the methods used, homogenizing the embryonic tissue represented the best culture, which reached the confluence state sooner. Six different morphologies were distinguished in the embryonic primary cultures of silkworm including fibroblast-like cells with three sub-forms of A to C, spindle shaped cells, spherical cells and epithelial-like cells. Also, developing primary cultures from B. mori using enzymatic method is not recommended because of its low efficiency.

Woolly poplar aphid, Phloeomyzus passerinii (Signoret), is considered as an important and serious pest of poplar in Iran and many countries. During 2002-2003, resistance and susceptibility of 12 poplar clones to P. passerinii were evaluated in Hamedan province of Iran. Number of formed aphid colonies found in a surface unit was counted three times during a growing season. The clones Populus alba 58/57, P. deltoides 72/51, P. deltoides missoriensis, P. x. euramericana 214, P. nigra 62/72, P. nigra 62/140 and P. nigra 62/149 were immune to the insect pest, but the remaining of P. nigra clones were infested variously. Analysis of variance conducted on obtained data, revealed a significant difference (α = 1%) between the clones. Mean infestation of P. nigra 56/72 was significantly higher than other studied clones in all sampling dates. Mean infestation of branches (at four main geographical directions of tree) was significantly different in the first sampling date, but not in two other dates. Natural enemies of the aphid collected in this region were Exochomus nigromaculatus (Goeze), Chilocorus bipustulatus L., Sympherobius pygmaeus (Rambur), Anthocoris sp., Orius sp. and Chiracanthium sp. The species, E. nigromaculatus and S. pygmaeusâ are reported for the first time on P. passerinii. The two parasitoid species, Thaumatomyia elongatula (Becker) and Pachyneuron sp., are reported for the first time on this pest from Iran. Mean density of T. elongatula and S. pygmaeusâ were higher than other natural enemy species and placed in same LSD test class. Mean density of the parasitoid wasp, Pachyneuron sp., was less than other natural enemies.

The carob moth, Ectomyelois ceratoniae (Zeller), belongs to the family Pyralidae and the subfamily Phycitinae. In spite of some features of sexual dimorphism in size and shape in the order Lepidoptera and the mentioned family, it has not been recorded in this species. In the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and walnut) were detected using landmark- based geometric morphometric and analysis of partial warp scores and centroid sizes. The analysis showed significant wing shape differences (fore wing: P = 1.315E-011, hind wing: P = 1.168E-007) which was the same on all tested hosts. Geometric changes in the fore and hind wing of both sexes were illustrated. Analyses of size showed wings of the females are bigger than those of the males (fore wing: F = 23.19, P = 0.000; hind wing: F = 16.73, P = 0.000) on tested hosts and in spite of allometric growth in test specimens, significant shape differences are still remain in constant size.
