A Laboratory Assessment of Two Local Strains of the Beauveria bassiana (Bals.) Vuill. against the Tetranychus urticae (Acari: Tetranychidae) and Their Potential as a Mycopesticide
This study was conducted to assess highly pathogenic Beauveria bassiana isolates to be used in biocontrol and to determine their potentials as mycopesticide. For this purpose, two B. bassiana isolates, which were locally isolated from T. urticae, were chosen. Firstly, three suspensions were investigated at the degree of humidity of 65 ± 5% and 100% RH. Secondly, these strains were selected acco...
متن کاملCompatibility of selected herbicides with entomopathogenic fungus Beauveria bassiana (Bals.) Vuill
The in vitro effect of five commonly used herbicides viz., pyridate, fluazifop-P-butyl, foramsulfuron, tembotrione and Smetolachlor on mycelial growth of entomopathogenic fungus Beauveria bassiana (ATCC 74040) was evaluated each at different concentrations: 100, 75, 50, 25, 12.5, 6.25 and 0% of recommended field application rate on PDA agar plates at 15 and 25°C. The herbicides tested were clas...

کنه تارتن دو نقطه ای.koch tetranychus urticae یکی از پلی فاژترین آفات شناخته شده محصولات کشاورزی در دنیا است. با توجه به اثرات نامطلوب استفاده از سموم شیمیایی و مقاومت در کنه های گیاهی، روش کنترل بیولوژیک به عنوان یک روش سازگار با محیط زیست مورد توجه قرار گرفته است.قارچ بیماریزای حشراتbeauveria bassiana (bals.) vuill. یکی از مهمترین پاتوژن ها در بندپایان است که نقش بسیار مهمی در تنظیم جمعیت کنه...
Biocontrol of almond bark beetle (Scolytus amygdali Geurin-Meneville, Coleoptera: Scolytidae) using Beauveria bassiana (Bals.) Vuill. (Deuteromycotina: Hyphomycetes).
AIMS To formulate the entomopathogenic fungus Beauveria bassiana in invert emulsion, then apply it against adults of almond bark beetle (Scolytus amygdali) under laboratory and field conditions. METHODS AND RESULTS The effect of formulated B. bassiana in invert emulsion against S. amygdali adults was shown by comparing the mortality percentage of adults exposed to the formulated fungus using ...
متن کاملPathogenicity of Metarhizium anisopliae (Metch) Sorok and Beauveria bassiana (Bals) Vuill to adult Phlebotomus duboscqi (Neveu-Lemaire) in the laboratory.
BACKGROUND & OBJECTIVES Biological control of sandflies using entomopathogenic fungi is a possible alternative to the expensive synthetic chemical control. It is potentially sustainable, less hazardous, and relatively inexpensive and merits further investigations. The objective of this study was to identify the most pathogenic fungal isolate(s) to sandflies in the laboratory. METHODS Isolates...
