The first report of Agrypon canaliculatum (Hym.: Ichneumonidae) as parasitoid of Yponomeuta evonymella (Lep.: Yponomeutidae) from Iran

During the study of natural enemies of insect pests of forest trees and shrubs in Arasbaran forest of Iranian province of East Azarbaijan, a number of larvae of Yponomeuta evonymella L. were collected on wild cherry trees. The specimens were reared in the laboratory, where parasitoid wasps of the family Ichneumonidae emerged and later identified as Agrypon canaliculatum (Ratzeburg, 1844). The identification was confirmed by the second author. This species is newly recorded from Iran

First report of an entomopathogenic nematode, Steinernema kraussei (Rhabditida, Steinernematidae) from Iran

During conduction a survey of entomopathogenic nematodes throughout Arasbaran forests and rangelands, north west of Iran in 2007-2008, an entomopathogenic nematode was isolated using Galleria baiting method from soil samples collected from rangelands, near Chichakloo, Varzeghan, East Azarbaijan. It was identified as Steinernema kraussei (Steiner, 1923) Travassos, 1927 based on morphology and morphometric characters, cross breeding test, as well as molecular data. This species can be separated from other members of the genus by medium body length of infective juvenile (818 μm), lateral field with eight ridges in which the central pair is less distinct than others, head smooth, long cephalic papillae, secretory-excretory pore located at the level of middle of esophagus and anterior to the nerve ring; broad, slightly yellowish and short spicules, low D% value and tail with fine mucron in males. The analysis of ITS-rDNA sequence placed Iranian population of S. kraussei in the âfeltiae - kraussei - oregonenseâ group in the clade that containing different isolates of the species. It has some morphological and morphometric differences such as long cephalic papillae of IJ, more curvature of spicules and absence of mucron in some males as compared with type species. The mentioned differences are considered as intraspecific variations, and the described population from Iran is another isolate of S. kraussei. This is the first record of S. kraussei from Iran

Morphology and molecular study of an entomopathogenic nematode, Steinernema bicornutum (Nematoda, Rhabditida, Steinernematidae) from Iran

An entomopathogenic nematode was isolated by Galleria baiting technique from soil samples collected near Marand, East Azarbaijan province, North-west of Iran during 2003. Based on morphological and morphometric characters, as well as molecular data it was identified as Steinernema bicornutum Tallosi, Peters & Ehlers, 1995. Morphometrics comparison of the isolate with the type species showed no obvious differences between them. Differences in ITS-rDNA PCR-RFLP were found between the Iranian isolate, i.e. IRA7, with the type (Yugoslavian) isolate. The RFLP analysis was able to distinguish Iranian isolate from the type population of S. bicornutum in the HinfI (four restriction sites in the type vs three restriction sites in the IRA7), Hin6I (550, 250 and 250 bp in the studied isolate vs 541 and 474 in the type isolate) and AluI profiles (715, 177 and 123 in the type and 710 and 220 in the IRA7). These molecular differences are considered as intraspecific variations, and the described population from Iran is another isolate of S. bicornutum

A survey on the response of the last instar larvae of acorn weevil, Curculio glandium (Col.: Curculionidae), to entomopathogenic nematodes Steinernema bicornutum and Heterorhabditis bacteriophora in the laboratory

The acorn weevil, Curculio glandium Marsham, is an important forest pest of oak trees in most of countries as well as Iran. The pest disturbs regeneration of host trees by feeding on their acorn. The necessitate to control the pest as well as limitations of chemical pesticide application in natural resources, different indigenous entomopathogenic nematodes (EPNs): Heterorhabditis bacteriophora and Steinernema bicornutum were tested under laboratory conditions upon the fifth instar larvae of acorn weevil collected from Arasbaran forest. In the first experiment, penetration assay was conducted using a suspension of 4000 IJs of the EPNs per 1 ml distilled water in multi-well plates. The plates were incubated for 40 h at 25ºC and dead larvae were dissected. Penetration percentage was %1.6 for H. bacteriophora and %0.55 for S. bicornutum. In the second experiment, H. bacteriophora and S. bicornutum were applied at different concentrations (0, 150, 250, 500, 1000 and 2000 IJs per 1ml of distilled water) in the 9 cm Petri plates lined with filter papers in order to test their capability of parasitization of the fifth instar larvae of C. glandium. The experiments were conducted at two temperature ranges (21-24ºC and 25-28ºC). Maximum mortality caused by H. bacteriophora and S. bicornutum were %58.3, %25 (at 21-24ºC) and %63.5, %30.5 (at 25-28ºC), respectively. Therefore, H. bacteriophora caused higher larval mortality comparing to S. bicornutum at both temperature ranges. Analysis of variance revealed significant nematode species and concentration as well as temperature effects on larval mortality. By increasing of concentration of nematode and temperature, larval mortality was raised. The highest penetration in larva and the highest mortality of fifth instar larvae of C. glandium was observed for H. bacteriophora under the both temperature ranges. Based on probit analysis, the LC50 of H. bacteriophora at two temperature ranges of 21-24ºC and 25-28ºC were determined 1331 and 1037 IJs/ml, respectively. Regression analysis showed significant relationship between concentrations and larval mortality in both nematodes and both temperature ranges. Therefore, H. bacteriophora comparing to S. bicornutum is more effective and can be suggested for complementary studies toward finding a suitable biocontrol agent of the pest

Physicochemical and sensorial properties of grapefruit jams as affected by processing

Jam is an effective and tasty way of preserving fruit. Jam processing procedures as well as storage conditions and duration are important factors for jam quality. Traditional jam processing involves the application of severe thermal treatments that imply undesirable changes in the product quality characteristics such as colour, texture, flavour and nutritional and functional value. In this work, osmotic dehydration (OD) and/or microwave energy (MW) was proven as adequate to obtain jam with the typical characteristics of water content, degree Brix, pH and water activity of jam obtained by conventional thermal heating. The sensory evaluation carried out to compare the product showed that samples submitted to more intense heating treatments (conventional or MW) had significantly higher scores in colour saturation, brightness, grapefruit taste and extensibility than OD or OD+MW ones. As deduced from the obtained results, OD treatment prevents grapefruit colour changes, and mild MW heating contributes to increase the consistency and decrease the extensibility of the obtained jam. In this way, OD+MW jam was preferred by assessors mainly due to its higher consistency. The sample obtained by this procedure was stable during storage.The authors would like to thank the Ministerio de Educacion y Ciencia for the financial support given throughout the Project AGL 2005-05994.

Nematode endoparasites do not codiversify with their stick insect hosts.

Host-parasite coevolution stems from reciprocal selection on host resistance and parasite infectivity, and can generate some of the strongest selective pressures known in nature. It is widely seen as a major driver of diversification, the most extreme case being parallel speciation in hosts and their associated parasites. Here, we report on endoparasitic nematodes, most likely members of the mermithid family, infecting different Timema stick insect species throughout California. The nematodes develop in the hemolymph of their insect host and kill it upon emergence, completely impeding host reproduction. Given the direct exposure of the endoparasites to the host's immune system in the hemolymph, and the consequences of infection on host fitness, we predicted that divergence among hosts may drive parallel divergence in the endoparasites. Our phylogenetic analyses suggested the presence of two differentiated endoparasite lineages. However, independently of whether the two lineages were considered separately or jointly, we found a complete lack of codivergence between the endoparasitic nematodes and their hosts in spite of extensive genetic variation among hosts and among parasites. Instead, there was strong isolation by distance among the endoparasitic nematodes, indicating that geography plays a more important role than host-related adaptations in driving parasite diversification in this system. The accumulating evidence for lack of codiversification between parasites and their hosts at macroevolutionary scales contrasts with the overwhelming evidence for coevolution within populations, and calls for studies linking micro- versus macroevolutionary dynamics in host-parasite interactions

The studied material is deposited in the arthropod collection of Research Institute of Forests and Rangelands

The Predictive Role of Emotional Intelligence and Perceived Parenting Styles in Happiness of Students

This study sought to determine the contribution of the variables of parenting style and emotional intelligence to happiness of high school students. The sample of the study was 345 students in Noorabad Mamasani, chosen through multi-stage random cluster sampling. For the purpose of data collection, three questionnaires were used, Oxford Happiness Questionnaire, Emotional Intelligence Questionnaire by Petrides and Furnham and Parenting Style Questionnaire by Baumrind. In order to compare happiness in terms of the variable of gender, independent-samples t-test was used. The findings showed that happiness was significantly different in males and females. Moreover, the results of analysis of regression showed that parenting styles and the components of emotional intelligence had a significant effect on happiness in both males and females. In addition, authoritative parenting style, self-awareness and permissive parenting style, respectively, accounted for 50% of happiness in males. However, in females, social skills and authoritative parenting style accounted for only 17% of happiness. Generally speaking, the findings suggest that the adopted parenting styles and their emotional intelligence play a very important role in explaining happiness
