Acute effect of low-dose thiacloprid exposure synergised by tebuconazole in a parasitoid wasp Universiteit Gent
Larval oral exposure to thiacloprid : dose-response toxicity testing in solitary bees, Osmia spp. (Hymenoptera: Megachilidae) Universiteit Gent
Characterisation of Two Wood-Waste and Coffee Bean Husk Biochars for the Removal of Micropollutants from Water Interuniversitair Micro-Electronica Centrum vzw Universiteit Hasselt Universiteit Gent
The inclusion of bioaugmented low-cost biochar in current wastewater treatment technologies is a promising way to enhance the removal and degradation of emerging contaminants. In this paper, the properties of two wood waste biochars (wood waste mix - AB, and date palm fiber wood - PDF), and coffee bean husks (COF), produced at four temperatures (350, 450, 500, 550 degrees C) were compared, and investigated in the presence of Geobacter ...
Risk assessment for side-effects of neonicotinoids against bumblebees with and without impairing foraging behaviour. Vrije Universiteit Brussel
Bombus terrestris bumblebees are important pollinators of wild flowers, and in modern agriculture they are used to guarantee pollination of vegetables and fruits. In the field it is likely that worker bees are exposed to pesticides during foraging. To date, several tests exist to assess lethal and sublethal side-effects of pesticides on bee survival, growth/development and reproduction. Within the context of ecotoxicology and insect physiology, ...
Conservation biological control of key pests of Brussels sprouts (Brassica oleracea L. gemmifera) Universiteit Gent
Brussels sprouts are attacked by a variety of herbivore pests from several insect families. The most important leaf feeding ones are the cabbage aphid, Brevicoryne brassicae (L.), the cabbage moth, Mamestra brassicae (L.) and the diamondback moth, Plutella xylostella (L.). As Brussels sprouts are a high yielding crop with an almost zero damage threshold, growers want to keep the sprouts free from damage by pest insects. Several measures are ...
Corrigendum: Characterisation of two wood-waste and coffee bean husk biochars for the removal of micropollutants from water Universiteit Hasselt
Development of an analytical method based on solid-phase extraction and LC-MS/MS for the monitoring of current-use pesticides and their metabolites in human urine Universiteit Antwerpen
Pyrethroids, organophosphorus pesticides and fipronil have been listed as priority chemi-cals in human biomonitoring studies because of their wide use and potential health effects in humans. The determination of 13 pesticides, including pyrethroids (deltamethrin, cyper-methrin, permethrin, cyfluthrin, bifenthrin), organophosphorus (chlorpyrifos, chlorpyrifos-methyl, and malathion), fipronil, neonicotinoids (imidacloprid, acetamiprid and ...
Short-term lab assessments and microcolonies are insufficient for the risk assessment of insecticides for bees KU Leuven
Risk assessment studies addressing effects of agrochemicals on bumblebees frequently use microcolonies. These are queenless colonies consisting of workers only in which typically one worker will lay unfertilized male-destined eggs. In the first tier of risk assessment for bees, short-term laboratory experiments (e.g. microcolonies) are used, the results of which will determine whether higher tier (semi-)field experiments are needed. To evaluate ...
Capacitive sensor based on molecularly imprinted polymers for detection of the insecticide imidacloprid in water Universiteit Gent
This manuscript reports on the development of a capacitive sensor for the detection of imidacloprid (IMD) in water samples based on molecularly imprinted polymers (MIPs). MIPs used as recognition elements were synthesized via a photo-initiated emulsion polymerization. The particles were carefully washed using a methanol (MeOH) / acetic acid mixture to ensure complete template removal and were then dried. The average size of the obtained ...
