متن کاملActivity and Persistence of Steinernema carpocapsae and Spodoptera exigua Nuclear Polyhedrosis Virus against S. exigua Larvae on Soybean.
Experiments were conducted to assess the effects of the entomopathogenic nematode Steinernema carpocapsae and Spodoptera exigua multinucleocapsid nuclear polyhedrosis virus (SeMNPV), alone and in combinations, on mortality of the beet armyworm, S. exigua, larvae on soybean. In 1991 tests, field-grown soybean plants were treated with S. carpocapsae at 0.3 and 0.6 nematodes/cm(2) of leaflet, SeMN...
متن کاملبررسی سیتوژنتیکی چند گونه مریم گلی salvia lachnoclyx, s. verticillata, s. virgata, s. hydrangea
این پژوهش به منظور شناخت تنوع ژنتیکی 8 جمعیت متعلق به 4 گونه گیاه دارویی salvia (مریم گلی) با استفاده از بررسی کروموزم های سلول های مریستمی نوک ریشه بذور با روش استو-فریک-هماتوکسیلین صورت گرفت. عدد کروموزومی جمعیت های هر گونه ثابت و گونه salvia hydrangea دارای 14=x2=n2، گونه s. virgata دارای 16=x2=n2، گونه s. lachnoclyx دارای 22=x2=n2 و گونه s. verticillata دارای 32=x4=n2 بودند. به منظور تعیین ...

The seasonal occurrence of the beet armyworm, Spodoptera exigua (Hübner), and the southern armyworm, Spodoptera eridania (Cramer), was monitored over a 2year period using International Pheromones, Ltd. Moth Traps baited with rubber septa impregnated with pheromone blends identified from conspecific females and also with pheromone emitted by live female beet armyworm moths. The pheromone blend...
متن کاملSynthesis of MWCNTs Using Monometallic and Bimetallic Combinations of Fe, Co and Ni Catalysts Supported on Nanometric SiC via TCVD
Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...
