Entomopathogenic microorganisms: their role in insect pest managementEgyptian Journal of Biological Pest Control - Tập 31 - Trang 1-8 - 2021
Bhabesh Deka, Chittaranjan Baruah, Azariah Babu
Entomopathogens are pathogenic to insect pests. Several types of naturally occurring, viz. fungus, bacteria, viruses, and nematodes, infect a range of insect pests and help manage crop growth. They offer several advantages over chemical pesticides, including being precise, safe, and ecologically sustainable. Agricultural systems are streamlined, and changes to natural ecosystems occur. Viruses, ba...... hiện toàn bộ
Potential of phytopathogenic fungal isolates as a biocontrol agent against some weedsEgyptian Journal of Biological Pest Control - Tập 30 Số 1 - 2020
Youssef M. M. Mohammed, Mohamed E. I. Badawy
AbstractBioherbicides afford satisfactory approach to overcome weed problem. Selection of new bioherbicides from phytopathogenic microbiota is essential for modern agricultural management, especially mycoherbicides. Thus, in the present investigation, 4 phytopathogenic fungi including Alternaria alternata YMM1, A... hiện toàn bộ
Increasing the efficacy of the cotton leaf worm Spodoptera littoralis nucleopolyhedrosis virus using certain essential oilsEgyptian Journal of Biological Pest Control - Tập 30 - Trang 1-7 - 2020
Waheed Ahmed Abdelhanid Sayed, Helmy El-Bendary, Alexandra El-Helaly
Baculoviruses inactivation by UV sunlight is considered one of the most important factors that reduce their potential use in insect management programs. The three antioxidant essential oils, marjoram, orange, and tea tree were tested as protective additives to the multiple nucleopolyhedrosis virus (SpliMNPV) against UV. The results revealed that the orange oil was promising for virus protection, w...... hiện toàn bộ
Evaluation of certain Penicillium frequentans isolates against Cercospora leaf spot disease of sugar beetEgyptian Journal of Biological Pest Control - Tập 28 - Trang 1-7 - 2018
Mansour M. El-Fawy, Rafeek M. I. El-Sharkawy, Kamal A. M. Abo-Elyousr
The impact of six local isolates of Penicillium frequentans recovered from healthy sugar beet (Beta vulgaris L.) leaves was evaluated against Cercospora beticola, the causal pathogen of Cercospora sugar beet leaf spot under laboratory and field conditions. In in vitro studies, all the six isolates were able to inhibit the mycelial growth of C. beticola with variation in their antagonistic capabili...... hiện toàn bộ
Antiviral activities of three Streptomyces spp. against Zucchini yellow mosaic virus (ZYMV) infecting squash (Cucurbita pepo L.) plantsEgyptian Journal of Biological Pest Control - Tập 33 - Trang 1-16 - 2023
Gamal A. M. Ghanem, Ahmed M. A. Mahmoud, Ahmed A. Kheder, Doha A. S. Gebily, Asmaa Osamy
Zucchini yellow mosaic virus (ZYMV) is the major devastating disease worldwide, which leads to substantial economic losses (up to 100%) to yield and fruits quality produced of squash plants. Application of agro-pesticides is efficient and incompatible with organic agriculture and reportedly has harmful effects on human health and ecosystem. Nowadays, Streptomyces spp., a rich source of potential b...... hiện toàn bộ
Molecular identification, characterization, and expression analysis of a novel trypsin inhibitor-like cysteine-rich peptide from the cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae)Egyptian Journal of Biological Pest Control - Tập 30 - Trang 1-7 - 2020
Muhammad Shakeel, Junaid Zafar
Trypsin inhibitor-like cysteine-rich domain (TIL)-type protease inhibitors have been reported to inhibit proteases such as trypsin, cathepsin, elastase, and chymotrypsin, and thus play a critical role in several physiological processes. However, the information about TIL peptides in insects is limited. In the present study, a novel cysteine-rich trypsin inhibitor-like protease, designated as HaTIL...... hiện toàn bộ
