Introduction

This document is a 10-day chronic oral toxicity test method for adult worker bees conducted under laboratory conditions. Pollinating insects such as bees can be exposed to various pollutants over time by storing and eating contaminated food in the hive, or foraging in contaminated areas. Plant protection products (PPP) or chemicals. In order to solve the above potential risks, adult worker bees can be fed and treated in the laboratory for 10 consecutive days. Food (sucrose solution) was used for chronic toxicity testing. Before using this document to test a mixture and obtain relevant data for a specified regulatory purpose, it should be considered whether doing so (in order to and why) can provide sufficient test results to achieve the above purposes. When there is a regulation that specifically requires the mixture to be tested, there is no need to have this concern. Chemical Bee (Apismellifera L.) Chronic oral toxicity test (10-day feeding method)

1 Scope
