Efficacy Of The Rodenticide Bromethalin In The Control Of Microtus Arvalis And Nesokia Indica In Alfalfa Fields, Alireza Khalilaria, Mohsen Morovati, Mehdi Naseri Jan 2007

Efficacy Of The Rodenticide Bromethalin In The Control Of Microtus Arvalis And Nesokia Indica In Alfalfa Fields, Alireza Khalilaria, Mohsen Morovati, Mehdi Naseri

Turkish Journal of Zoology

Rodents cause huge losses to agricultural crops annually. During outbreaks, this pest can cause irreversibly high damage. Solely non-chemical control measures have not been successful in reducing the population of this pest; therefore, the use of chemical rodenticides, especially on crops like alfalfa, is unavoidable. Bromethalin is a neurotoxic, acute, single-dose rodenticide with high efficacy, and since it is mostly used in wax formulation it is not attractive to non-target organisms, and hence is not very dangerous. Bromethalin 0.01% was tested in alfalfa fields of west Azerbaijan, Tehran, and Kerman provinces in completely randomised treatment blocks with 4 treatments (bromethalin …


Biometrical Study Of Artemia Urmiana (Anostraca: Artemiidae) Cysts Harvested From Lake Urmia (West Azerbaijan, Iran), Alireza Asem, Nasrullah Rastegar-Pouyani, Naser Agh Jan 2007

Biometrical Study Of Artemia Urmiana (Anostraca: Artemiidae) Cysts Harvested From Lake Urmia (West Azerbaijan, Iran), Alireza Asem, Nasrullah Rastegar-Pouyani, Naser Agh

Turkish Journal of Zoology

Artemia urmiana was reported from Lake Urmia by Günther in 1899. The objectives of the present study were to investigate the diameter of untreated and decapsulated cysts and chorion thickness at 26 stations in Lake Urmia. One-way ANOVA (Tukey test, P < 0.05) was used for analyzing the data. Only 31 pair means of untreated cysts among 26 stations showed significant differences, but, on the other hand, 157 pair means of decapsulated cysts among stations showed significant differences. There was a high variation in cyst diameter among the different localities in Lake Urmia. It was shown that this lake consists of recognizable sections producing cysts with different hatching characteristics, which can be used for diverse aquacultural purposes.


The Taxonomy And Variation Of Leaf Anatomical Characters In The Genus Aegilops L. (Poaceae) In Iran, Navaz Kharazian Jan 2007

The Taxonomy And Variation Of Leaf Anatomical Characters In The Genus Aegilops L. (Poaceae) In Iran, Navaz Kharazian

Turkish Journal of Botany

This study concerns the evaluation of leaf anatomical characters (7 qualitative and 12 quantitative characters) among 26 accessions of the Aegilops L. species. The results of this study showed that the anatomical characters have high variation in the width of stomata, the number of long cells in the adaxial epidermis, the number of short cells in the abaxial epidermis, the number of stomata in the abaxial epidermis, the occurrence of prickles in the adaxial epidermis, and the width of phloem cells. The variations in anatomical characters were related to the cold and warm areas of Iran and commonly occurred among …

New And Interesting Moss Records For Iran, Ahmad Ghahreman, Moussa Faridi, Saeed Shirzadian, Farideh Attar

Turkish Journal of Botany

Four moss species, namely, Tetraphis pellucida Hedw. (Tetraphidaceae), Ulota crispa (Hedw.) Brid. (Orthotrichaceae), Haplohymenium triste (Ces.) Kindb. (Anomodontaceae), and Rhynchostegiella litorea (De Not.) Limpr. (Brachytheciaceae) are recorded from Iran. The specimens were collected from Kheiroodkenar Forest, Mazandaran Province (north of Iran).
