Lethal and sub-lethal toxicities of pesticides in bees
|
Chemical hazard assessment for bees generally starts with laboratory testing of acute effects in the honeybee, Apis mellifera. Whether acute effects observed in this model species translate to different species and longer exposure periods are key issues for robust hazard assessment. effect. |

Long-term yield trends of insect-pollinated crops vary regionally
|
Abstract Time series data on crop yields for two main wind-pollinated crops (barley and wheat) and for three crops benefitting from insect pollination (turnip rapeseed, caraway, and black currant), were compiled from official agricultural statistics. |

Long-wave infrared imaging for non-invasive beehive population assessment
|
Long-wave infrared imaging is used for non-invasive assessment of the internal population of honey bee colonies. The radiometrically calibrated camera signal is related to the number of frames that are populated by bees inside each hive. |
