Read More Mature seeds of Melia azedarach were harvested from north of Iran, Mazandaran province. The seeds were dried in the shade at room temperature (about 25ºC), powdered by blender. Extraction from the seeds powder was done in the Soxhlet extractor. Water soluble and Non-water-soluble components of the seed powder extract were separated by dichloromethane/water. In addition, Tween 85 was added to the extract and an 11% formulation was made from the seed extract in the laboratory. The toxicity of formulation to the root-knot nematode, Meloidogyne incognita, was studied in laboratory and pot experiments. Application rates of formulation were 0.125, 0.25, 0.5, 1, 2, 4, 8 and 16 percent for the laboratory experiment in order to determine their effects on motility and mortality of second-stage juveniles (J2) after two different exposure times (24 and 48 h). In pot experiment, 0.125, 0.25, 0.5, 1, 2 and 4 percent of the formulation were applied on nematode activity and plant growth components of tomato (Solanum lycopersicum). Neither J2 immobility nor mortality was observed in treatments with 0.125 and 0.25% doses. Exposure time was significantly (p<5%) affected J2 mortality. After 24 h, J2 mortality was 0.0, 44.30 and 76 % following treatment with 4, 8 and 16% formulation, respectively, while 100% J2 mortality was recorded for the same concentrations, after 48 h of exposure. In the pot experiment, all of the concentrations significantly reduced the numbers of galls, egg masses and eggs in tomato roots, J2s in soil and tomato roots and overall nematode population. Treatment of 4% of formulation was toxic to tomato plants and significantly reduced tomato root and stem length and fresh weights in comparison to control. Results of the laboratory experiments show good stability of the formulation. In general, 1 and 2% concentrations of the formulation controlled root knot nematode and improved tomato growth parameters under the laboratory conditions as compared with the control. Use of the recommended concentrations of this new formulation, could be a natural and eco friendly way to control root knot nematode and to reduce hazardous effects of chemical pesticides.

Read More A survey was conducted to collect and identify the parasitoid wasps of Pieris rapae (L.) (Lep.: Pieridae) and Plutella xylostella (L.) (Lep.: Plutellidae) in cauliflower fields of Tehran province, Iran (N=35°30′, E=51°17′, 1046m a.s.l.) during 2012. Larvae and pupae of P. rapae and p. xylostella were collected and reared separately in plastic jars under laboratory conditions (22±2°, RH= 65±2%, L:D= 14:8) until the adults of butterfly or parasitoids were appeared. Five hymenopterous parasitoids were collected and identified as: Oomyzuss sokolowskii (Kurdjumovo, 1912) (Hym.: Eulophidae), Pteromalus sp. (Hym.: Pteromalidae), Cotesia vestalis (Kurdjumov, 1912) (Hym.: Braconidae), Diadegma anurum (Thomson, 1877) and Hyposoter ebeninus (Gravenhorst, 1829) (Hym.: Ichenumonidae, Campopleginae). The last species is a new record for the fauna of Iran (1, 4). Specimens of this species were deposited in the insect museum of the University of Turku, Finland and Shahed University, Iran. Hyposoter ebeninus (Gravenhorst, 1829): Material examined: IRAN, Tehran province (N=35°30′, E=51°17′, 1046a.s.l.), 5 May 2012, 1♀, 15 June 2012, 1♀ General distribution: Austria; Azerbaijan; Belarus; Belgium; Bulgaria; China; Croatia; Czech Republic; Czechoslovakia; Finland; France; Germany; Hungary; India; Italy; Latvia; Moldova; Pakistan; Poland; Portugal; Romania; Russia; Serbia & Montenegro; Spain; Sweden; Switzerland; Tunisia; Turkey; Turkmenistan; Ukraine; United Kingdom (4) and Iran (new record). Diagnostic characters: Hyposoter ebeninus can be distinguished from its nearest species, H. rhodocerae (Rondani, 1877), by the combination of the following characters: mandibles are pale yellow at the base and the hind tibia apically not or hardly darkened. In H. rhodocerae the mandibles are yellowish red to reddish brown and distinctly black at the base and the hind tibia apically darkened. The important differences are in the host selection and distribution: H. rhodocerae parasitizes exclusively Gonepteryx cleopatra and G. rhamni and has been reported from Germany, Ireland and Italy. While H. ebeninus was known as a parasite of the species of the genera Pieris and Euchloe and distributed in Central, Southern and Eastern Europe, North Africa, Western Asia to India (2, 4). Hyposoter species are considered as Koinobiont larval endoparasitoids of mostly Lepidoptera (butterflies and moths), but also beetle and wasp larvae (3).
