Entomopathogenic microorganisms: their role in insect pest management
Egyptian 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
First report of entomopathogenic nematode Steinernema surkhetense and its pathogenic potential to larvae of the Greater Wax Moth (Galleria mellonella L.) in Vietnam
Egyptian Journal of Biological Pest Control - Tập 31 - Trang 1-7 - 2021
Phap Quang Trinh, Duyen Thi Nguyen, Linh Thi Mai Le, Tien Huu Nguyen
Entomopathogenic nematodes (EPNs) are evidently a useful nematode group for the biocontrol of insect pests. It is well known that efficacy of different EPN strains, even belonging to the same species, can be significantly varied in different localities. Therefore, exploring EPNs and testing their efficacy in various ecological regions is of crucial importance to find out more efficient EPN strains...... hiện toàn bộ
Potential of phytopathogenic fungal isolates as a biocontrol agent against some weeds
Egyptian 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 oils
Egyptian 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 beet
Egyptian 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.) plants
Egyptian 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
Pathogenicity induced by indigenous Beauveria bassiana isolate in different life stages of the cotton leafworm, Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) under laboratory conditions
Egyptian Journal of Biological Pest Control - Tập 31 - Trang 1-7 - 2021
Yasmin Adel Fergani, Elsayed Abd Elhameed Refaei
The invincible effects of the entomopathogenic fungi (EPF) under appropriate circumstances compensate for the flaws of chemical insecticides in the control programs. Beauveria bassiana is one of the most elaborated EPF of pest control all over the world. The potential of using the B. bassiana isolate (Y-F_ITS1) was examined against different larval instars (L2, L3, L4, and L5), pupae, and eggs of ...... hiện toàn bộ
Efficacy of Thai indigenous entomopathogenic nematodes for controlling fall armyworm (Spodoptera frugiperda) (J. E. Smith)(Lepidoptera; Noctuidae)
Egyptian Journal of Biological Pest Control - Tập 31 - Trang 1-7 - 2021
Wandee Wattanachaiyingcharoen, Ongpo Lepcha, Apichat Vitta, Det Wattanachaiyingcharoen
Under laboratory and greenhouse conditions, the virulence of 2 isolates of Thai indigenous entomopathogenic nematodes (EPNs) in controlling the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera; Noctuidae), was demonstrated. Six EPNs dosages were tested against 2 larval instars of FAW under the laboratory conditions, while 2 different concentrations were tested under the greenh...... hiện toàn bộ
In vitro antagonistic activity of Trichoderma harzianum and T. viride strains compared to carbendazim fungicide against the fungal phytopathogens of Sorghum bicolor (L.) Moench
Egyptian Journal of Biological Pest Control - Tập 31 Số 1 - 2021
Mohamed Taha Yassin, Ashraf A. Mostafa, Abdulaziz A. Al–Askar
Abstract Background High losses of sorghum crops due to fungal diseases, such as grain mold and stalk rot, are economically harmful and cause increased use of environmentally damaging chemical fungicides, which also are detrimental to human health. Hence, finding safe and effective ways to manage fu...... 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
