Cowpea yield improvement is done by adding agricultural inputs. The use of natural substances as pesticides being encouraged to fight against cowpea field pests. pesticidal potentials Azadirachta indica and Boswellia dalzielii water extracts, Metarhizium anisopliae, alone in combination with plant a commercial synthetic pesticide (Decis®) were tested on two varieties cowpeas, Vigna unguiculata ...

شته مومی کلم یکی از آفات مهم گیاهان تیره کلم می­باشد که با تغذیه مستقیم از شیره گیاهی و انتقال ویروس­های گیاهی خسارت می­زند. روش رایج در کنترل آفت مذکور استفاده از حشره­کش­های شیمیایی است. اما آثار سوء استفاده از آنها موجب افزایش توجه به استفاده از ترکیبات و عوامل سازگار با محیط شده است. لذا در این تحقیق قدرت بیمارگری جدایه­های DEMI001 و V245 از قارچ Metarhizium anisopliae (Metch.) Sorokin روی ...

Hyalomma anatolicum anatolicum and Haemaphysalis punctata larval ticks were shown to be susceptible to different strains of entomopathogenic fungi Metarhizium anisopliae under laboratory conditions. To determine the susceptibility of H. anatolicum anatolicum and H. punctata to M. anisopliae, two suspensions of conidia were used (103 and 104 spores/ml). The treatments were conducted by immersing...

Aedes aegypti is the vector of a wide range of diseases (e.g. yellow fever, dengue, Chikungunya and Zika) which impact on over half the world's population. Entomopathogenic fungi such as Metarhizium anisopliae and Beauveria bassiana have been found to be highly efficacious in killing mosquito larvae but only now are the underlying mechanisms for pathogenesis being elucidated. Recently it was sh...

BACKGROUND Increasing incidences of insecticide resistance in malaria vectors are threatening the sustainable use of contemporary chemical vector control measures. Fungal entomopathogens provide a possible additional tool for the control of insecticide-resistant malaria mosquitoes. This study investigated the compatibility of the pyrethroid insecticide permethrin and two mosquito-pathogenic fun...

The susceptibility of the egg, pupa, and adult of Haematobia irritans (L.) (Diptera: Muscidae) to isolates of the fungi Metarhizium anisopliae (Metsch.) Sor., Beauveria bassiana (Bals.) Vuill., and Paecilomyces fumosoroseus (Wize) Brown and Smith, was evaluated under laboratory conditions. Groups of 20 eggs than 4 h old, pupae less than 48h old and adults were sprayed with a conidial suspension...
