Entomopathogenic microorganisms: their role in insect pest management
Egyptian Journal of Biological Pest Control - Tập 31 - Trang 1-8 - 2021
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...
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
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...
Potential of phytopathogenic fungal isolates as a biocontrol agent against some weeds
Egyptian Journal of Biological Pest Control - Tập 30 Số 1 - 2020
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.
tenuissima YMM3, Chaetomium globosum YMM2, and Nigrospora oryzae YMM4 were
isolated ...
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
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...
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
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...
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
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...
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
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 ...
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
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...
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
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 fungal diseases
of sorghum is urgently needed. Results In the present study, the antagonistic
activiti...
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
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...
