An RNAi-Based Vulnerability in the White-Backed Planthopper: Silencing SfHSP70-8 Impairs Thermotolerance and Insecticide Susceptibility in a Key Rice Pest

Agronomy
Heat shock protein 70 (HSP70) serves as a critical molecular chaperone governing environmental stress responses in insects. This study aimed to characterize the expression pattern of SfHSP70-8 and determine its functional role in thermotolerance and ...

Assessment of fall‐back MRLs for revoked CXLs previously implemented in the EU legislation and review of the JMPR evaluation of the toxicological data related to pyrasulfotole, pyraziflumid, spiropidion and tetraniliprole

EFSA Journal, Volume 22, Issue 5, May 2024.
Abstract In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to propose fall‐back maximum residue levels (MRLs) for recently revoked Codex MRLs that have been previously implemented in the EU legislation. Overall, MRLs for 12 a.s. are concerned, i.e.

Genome-wide identification of ABC transporters and their contribution to triflumezopyrim susceptibility regulated by microRNAs in Laodelphax striatellus.

Pesticide Biochemistry and Physiology
The small brown planthopper (SBPH), Laodelphax striatellus, is a highly destructive pest, which seriously threatens the production of high-quality rice. Triflumezopyrim, a novel insecticide widely used against planthoppers, which will inevitably produce ...

Overexpression of the transporter SfABCH4 contributes to metabolic resistance to triflumezopyrim in Sogatella furcifera (Hemiptera: Delphacidae).

Pest Management Science
BACKGROUND The white-backed planthopper, Sogatella furcifera (Horváth), is a major migratory pest of rice in Asia. Triflumezopyrim (TFM) is highly effective against S. furcifera, but the mechanisms underlying resistance remain poorly understood.

Neonicotinoids and Other Insect Nicotinic Receptor Competitive Modulators: Progress and Prospects

, 2018
Neonicotinoids (neonics) are remarkably effective as plant systemics to control sucking insects and for flea control on dogs and cats. The nitroimines imidacloprid, clothianidin, thiamethoxam, and dinotefuran are the leaders among the seven commercial ...
