Gall-inducing Aphids (Hemiptera: Aphidoidea: Eriosomatinae) Associated with Salicaceae and Ulmaceae in Razavi Khorasan Province, with New Records for Fauna of Iran

A survey of gall-inducing aphids on elm and poplar trees was carried out during 2017 in Razavi Khorasan province, NE Iran. As a result, 15 species of gall-inducing aphids from 5 genera, all belonging to the subfamily Eriosomatinae, were recorded on 6 host plant species. The collected species included the genera Eriosoma, Kaltenbachiella, Pemphigus, Tetraneura and Thecabius. Pemphigus passeki Börner (Hemiptera: Aphididae) and Pemphigus populinigrae (Schrank) (Hemiptera: Aphididae) on Populus nigra var. italica (Salicaceae) were new records for the Iranian aphid fauna. Both new recorded species belong to the tribe Pem-phigini, subfamily Eriosomatinae. Among the identified species, 8 aphid species were new records for Razavi Khorasan province

Study on the gene expression of Chit1 and Chit2 in Beauveria bassiana during the parasitic interaction with onion thrips, Thrips tabaci (Thys.: Thripidae)

The host-pathogen interaction is a very complex process. Like many entomopathogenic fungi during infection process, Beauveria bassiana produces enzymes which are able to destroy the cuticle of insects in order to penetrate into the host. Chitinases are considered to be the important enzymes for the hydrolysis of chitin and play an important role in the biological control of various pests including onion thrips, Thrips tabaci Lind. In the present study, specific primers for CHit1 and CHit2 genes were designed to study the expression pattern of these two chitinases from B. bassiana IRAN 789C strain before and after interaction with the second instar larvae of onion thrips using RT-PCR. Larval inoculation was carried out using three concentrations, 104, 105 and 106 conidia per ml. The results showed that both genes were expressed in all conidial concentrations, after parasitic interaction. Increasing the conidial concentration of B. bassiana caused the upregulation of chitinases expression level. Expression of these genes during the parasitic interaction of the fungus and insect larvae reflects the importance of chitinases gene as an effective factor in biological control of target organisms

Life table parameters and development of Aphis nerri (Hem.: Aphididae) at five different temperatures under laboratory conditions

An investigation was carried out to study the life history of Aphis nerri Boyer de Fonscolombe on oleander, Nerium oleander L., under laboratory conditions (RH of 70 ± 5% and a 16: 8 (L: D) h photoperiod) based on the age-stage, two-sex life table at 10, 15, 20, 25 and 30 ºC. Duration of total pre-adult stages was 35.61 ± 0.833, 19.6 ± 0.343, 12.02 ± 0.243, 9.12 ± 0.182 and 7.42 ± 0.115 days at 10, 15, 20, 25 and 30 ºC, respectively. As temperature increased, the developmental time and longevity of the A. nerri shortened. The shortest developmental time (17.72 ± 0.244 days) and longevity (10.3 ± 0.234 days) were obtained at 30 ºC. With decreasing temperature, age-stage survivorship (lx) extended. Maximum fecundity of females was observed at 25 ºC with 25.54 ± 0.76 nymphs per female. The intrinsic rates of increase (r) at these temperatures were 0.012 ± 0.0014, 0.075 ± 0.0016, 0.13 ± 0.001, 0.23 ± 0.003 and 0.24 ± 0.003 d-1, respectively. The highest net reproductive rate (R0) was at 25 ºC (25.56 ± 0.73) and the lowest value was at 10 ºC (2.58 ± 0.28). According to our results, 25-30 ºC were the optimum temperature range for A. nerri population growth

A Study of the Prevalence of Psychiatric Disorders in Patients with Methamphetamine-Induced Psychosis

Abstract Background: The abuse of narcotic drugs and psychotropic substances such as amphetamines and ecstasy has had a growing trend. Tachycardia, increased blood pressure, hallucinations, panic attacks, and psychosis are the negative effects of methamphetamine abuse. The present study aimed to assess psychiatric disorders associated with methamphetamine-induced psychotic disorder. Methods: This cross-sectional study was performed from October 2013 to March 2014 on 165 patients hospitalized at Shahid Beheshti Hospital in Kerman, Iran, and diagnosed with psychosis induced by methamphetamine abuse within the previous 6 months. Study subjects were selected via census method. Based on the exclusion criteria and due to the lack of cooperation of some patients, 121 patients were enrolled in the study. Research data were gathered using clinical interviews, the Yale-Brown obsessive compulsive scale (Y-BOCS), Hamilton anxiety scale (HAM-A) and Hamilton rating scale for depression (HRSD), Young mania rating scale (YMRS), substance dependence severity scale (SDSS), positive and negative syndrome scale (PANSS), and clinical global impression (CGI) scale. The data analysis was performed using SPSS software, descriptive statistics, and ANOVA. Findings: Among the 121 patients of the sample group, 4 patients (3.3%) had anxiety, 58 patients (47.9%) depression, 30 patients (24.8%) obsessive-compulsive disorder (OCD), 20 patients (16.5%) bipolar mood disorder (BMD), 8 patients (6.6%) persistent psychotic symptoms, 85 patients (70.2%) personality disorder, and 36 patients (29.8%) had no personality disorders. The highest prevalence was related to borderline personality disorder (35.5%). However, 45 patients (37.2%) had no impairment associated with methamphetamine-induced psychosis. Conclusion: It seems that there is comorbidity between psychiatric disorders, including mood disorders, especially depressive disorder, childhood history of attention deficit hyperactivity disorder (ADHD), bipolar disorder, and personality disorders such as borderline personality disorder, and antisocial personality disorders, and methamphetamine abuse. Keywords: Methamphetamine, Depression, Anxiety, Obsessive-compulsive disorder, Manic disorder, Sustained psychotic symptoms, Personality disorde

AMBULATORY BLOOD PRESSURE PATTERNS IN PATIENTS WITH RETINAL VEIN OCCLUSION

Failure of blood pressure (BP) to dip during sleep (non-dipper pattern) is associated with cardiovascular disease (CVD) and stroke. The prevalence and degree of non-dipping and masked hypertension in patients with retinal vein occlusion (RVO), which is associated with stroke, has not been previously examined

Comparative development, reproduction and life table parameters of three populations of Thrips tabaci (Thysanoptera: Thripidae) on onion and tobacco

An investigation was carried out to study the developmental time, reproduction and life table of three populations of the onion thrips, Thrips tabaci Lindeman, on onion (Khorasan and Golestan populations) and also on tobacco (Mazandaran population) in the laboratory at 25°C, 50% RH and 16: 8 h L: D. The total life cycle from egg to adult of Khorasan, Golestan and Mazandaran populations were gauged as 15.22, 14.66 and 17.82 days, respectively. However, theses populations showed 30%, 38% and 58% immature mortality, respectively. The females of T. tabaci laid 29.5, 27.7 and 26.3 eggs averagely, and had a mean longevity of 18.0, 17.78 and 19.07 days in Khorasan Razavi, Golestan and Mazandaran populations, respectively. The net reproductive rate (R0) was 19.75, 18.48 and 10.84, and the intrinsic rate of increase (rm) was 0.143, 0.141 and 0.096 in Khorasan Razavi, Golestan and Mazandaran populations, respectively. Khorasan Razavi and Golestan populations (both reared on onion) had similar developmental time, mortality and life table parameters, while Mazandaran population (on tobacco) yielded significantly different values. Based on the differences of development, fecundity and life table parameters, there might be two distinct populations exploiting onion and tobacco in Iran
