Peer review of the pesticide risk assessment for bees for the active substance imidacloprid considering the uses as seed treatments and granules

EFSA Journal, 2018
The EFSA was asked by the European Commission to perform an updated risk assessment of neonicotinoids, including imidacloprid, as regards the risk to bees, as a follow‐up of previous mandates received from the European Commission on neonicotinoids.

Interference of ATP‐Binding Cassette Transporter by Functional Nano‐Delivery System for High Efficiency Management of Insecticide‐Resistant Nilaparvata lugens

Advanced Science, EarlyView.
A ZIF‐90 nanocarrier delivers dinotefuran and suppresses NlABCG3 and NlABCH1 in resistant Nilaparvata lugens. This system combines pH/ATP‐triggered release with enhanced foliar retention, improving efficacy while sparing honeybees and promoting rice growth, offering a promising resistance‐breaking strategy.
