Improving Mitochondrial Function Protects Bumblebees from Neonicotinoid Pesticides
Global pollination is threatened by declining insect pollinator populations that may be linked to neonicotinoid pesticide use. Neonicotinoids over stimulate neurons and depolarize their mitochondria, producing immobility and death. However, mitochondrial function can be improved by near infrared light absorbed by cytochrome c oxidase in mitochondrial respiration. In flies, daily exposure to 670...
متن کاملNeonicotinoid pesticides severely affect honey bee queens
Queen health is crucial to colony survival of social bees. Recently, queen failure has been proposed to be a major driver of managed honey bee colony losses, yet few data exist concerning effects of environmental stressors on queens. Here we demonstrate for the first time that exposure to field-realistic concentrations of neonicotinoid pesticides during development can severely affect queens of...
متن کامل0033. Hypothermia protects brain mitochondrial function from hypoxia in sepsis
Methods Mice (C57/bl6) were injected intraperitoneally with lipopolysaccharide (LPS) (5 mg/kg; n = 15) or saline (0.01 ml/g; n = 6). Six hours later, the cerebral cortex was exposed and mitochondrial function assessed using the inherent fluorescence of flavin adenine dinucleotide (FAD). The mice spontaneously breathed a sequence of 21% oxygen (room air), 100%, 21%, 15%, 21% and 10% for 5 minute...
متن کاملMitochondrial telomerase reverse transcriptase binds to and protects mitochondrial DNA and function from damage.
OBJECTIVE The enzyme telomerase and its catalytic subunit the telomerase reverse transcriptase (TERT) are important for maintenance of telomere length in the nucleus. Recent studies provided evidence for a mitochondrial localization of TERT. Therefore, we investigated the exact localization of TERT within the mitochondria and its function. METHODS AND RESULTS Here, we demonstrate that TERT is...
متن کاملNeonicotinoid pesticides can reduce honeybee colony genetic diversity
Neonicotinoid insecticides can cause a variety of adverse sub-lethal effects in bees. In social species such as the honeybee, Apis mellifera, queens are essential for reproduction and colony functioning. Therefore, any negative effect of these agricultural chemicals on the mating success of queens may have serious consequences for the fitness of the entire colony. Queens were exposed to the com...
