Entwicklung von Calliphora vicina unter Nahrungszugabe von Methadon

Methadone determination in puparia and its effect on the development of Lucilia sericata (Diptera, Calliphoridae)

“…The developmental time is similar to previous studies [16,18,37]. In our study, the window of development is similar for all treatments.…”

“…Spiked concentrations were selected based on reports of human fatalities [23] and on the previous works by Hecht et al [16] and Strehler et al [18]. Each meat batch was mixed in a Waring blender (VWR, Leuven, Belgium) for 5 min at ambient temperature to ensure a uniform spread of methadone.…”

“…Some physiological parameters such as sex-ratio and mortality are not well investigated [14][15][16] and could affect blowfly development indirectly. Entomotoxicological studies involving drugs and especially opioids (Table 1) seem to indicate different development rates responses in necrophagous flies [14][15][16][17][18][19][20]; it can be increased, retarded, or remain unchanged [21].…”

Analysis of the effect of methadone and temperature on the development rate of Calliphora vicina (Diptera: Calliphoridae): A forensically important fly

“…With respect to larval growth rates, this study determined that the development of C. vicina is affected by methadone only in high concentrations. This finding is similar to a previous study that used different species and feeding substrates (Gosselin et al 2011;Strehler 2008). Gosselin et al (2011) identified methadone and its metabolite (EDDP) in Lucilia sericata pupae only at high concentrations (8.4 µg/g).…”

Effect of different post-feeding intervals on the total time of development of the blowfly Lucilia sericata (Diptera: Calliphoridae)

“…The actual definition of the onset of the post-feeding phase, namely the leaving of the food source [10,11], was supplemented by three more preconditions to assure that the specimens had definitely reached this stage when used in the experiments. Firstly, as an initial reference point, an average minimum age of the larvae had to be fulfilled; according to Grassberger and Reiter [9], this is reached after 85 h at 25 8C by L. sericata.…”
