The Buzz on Insecticides: A Review of Uses, Molecular Structures, Targets, Adverse Effects, and Alternatives

open access: yesMolecules, 2023
Insecticides play a critical role in controlling the spread of insect-borne diseases and preserving crop health. These chemical substances are specifically formulated to kill or manage insect populations.

Nicotinic acetylcholine receptor modulator insecticides act on diverse receptor subtypes with distinct subunit compositions

open access: yesPLoS Genetics, 2022
Insect nicotinic acetylcholine receptors (nAChRs) are pentameric ligand-gated ion channels mainly expressed in the central nervous system of insects. They are the directed targets of many insecticides, including neonicotinoids, which are the most widely ...

Interaction of Insecticides and Fungicides in Bees

open access: yesFrontiers in Insect Science, 2022
Honeybees and wild bees are among the most important pollinators of both wild and cultivated landscapes. In recent years, however, a significant decline in these pollinators has been recorded. This decrease can have many causes including the heavy use of

The Metarhizium anisopliae Strains Expressing dsRNA of the NlCHSA Enhance Virulence to the Brown Planthopper Nilaparvata lugens

open access: yesAgriculture, 2022
Metarhizium anisopliae is a broad-spectrum entomopathogenic fungus with large-scale applications in pest control; however, its slow-killing action is a limiting factor. To enhance fungal virulence, we constructed transgenic M.

Pathogenicity induced by indigenous Beauveria bassiana isolate in different life stages of the cotton leafworm, Spodoptera littoralis (Boisduval) (Lepidoptera: Noctuidae) under laboratory conditions

open access: yesEgyptian Journal of Biological Pest Control, 2021
Background 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

Disruption of a C69-Family Cysteine Dipeptidase Gene Enhances Heat Shock and UV-B Tolerances in Metarhizium acridum

open access: yesFrontiers in Microbiology, 2020
In fungi, peptidases play a crucial role in adaptability. At present, the roles of peptidases in ultraviolet (UV) and thermal tolerance are still unclear. In this study, a C69-family cysteine dipeptidase of the entomopathogenic fungus Metarhizium acridum,

Phytotoxicity of the combination of some insecticides and fungicides on the ornamental species Petunia sp. [PDF]

open access: yesPoljoprivreda, 2016
In the production of ornamental plants, it is often necessary to combine plant protection products (PPPs) for simultaneous pest control. The use of a combination of PPPs often leads to phytotoxicity.

Ethanol Dehydrogenase I Contributes to Growth and Sporulation Under Low Oxygen Condition via Detoxification of Acetaldehyde in Metarhizium acridum

open access: yesFrontiers in Microbiology, 2018
The entomopathogenic fungi encounter hypoxic conditions in both nature and artificial culture. Alcohol dehydrogenases (ADHs) are a group of oxidoreductases that occur in many organisms.

Do novel insecticides pose a threat to beneficial insects?

open access: yesProceedings of the Royal Society B, 2020
Systemic insecticides, such as neonicotinoids, are a major contributor towards beneficial insect declines. This has led to bans and restrictions on neonicotinoid use globally, most noticeably in the European Union, where four commonly used neonicotinoids
