Determination of Malathion levels and its effect on the development of Chrysomya megacephala (Fabricius) in South China

Post-embriononic development of Chrysomya putoria(Diptera: Calliphoridae) on a diet containing ampicillin in different concentrations

“…This pathology is caused by species of the Calliphoridae family, mainly C. putoria, which has scavenger/necrophagic behaviour and develops in dead tissues (corpses) or necrotic wounds of living hosts (Guimaraes and Pavavero 1999). It is known that certain chemicals and hormones exert a deleterious effect on insect development (Carvalho et al 2001, 2012, Liu et al 2009, Gosselin et al 2011. However, the effect of antibiotics such as ampicillin on the development of fl y larvae remains unknown.…”

“…To evaluate the effects of different substances on fly development, many authors have used guinea pig tissues (Carvalho et al 2001, George et al 2009, Liu et al 2009) in addition to natural diet along with the substance to be tested (Grella et al 2007, Parry et al 2011. However, artifi cial diets can be used to homogeneously introduce substances in treatments, dispensing with the need for cobaios, which are expensive to handle (Soto 2008).…”

“…Many substances as drugs, or their metabolites, can affect the development of arthropods of forensic importance when present in the cadavers that they colonize (Introna et al 2001). Substances such as scopolamine, buscopan, malathion, diazepam and methadone decrease the development rate of insects (Carvalho et al 2001, 2012, Grella et al 2007, Liu et al 2009, Gosselin et al 2011. In addition, increased larval development was observed when insects were exposed to heroin, methamphetamine, codeine and paracetamol (Goff et al 1991, Carvalho et al 2004, O`Brien and Turner 2004.…”

Analysis of Some Selected Persistent Organic Chlorinated Pesticides in Marine Water and Food Stuffs by Differential Pulse‐Cathodic Stripping Voltammetry

“…The detector and the injector temperature were maintained at 280 8C. The column was held isothermally at 50 8C min À1 , then the temperature was programmed at 25 8C min À1 to 150 8C and finally programmed at 10 8C min À1 from 125 to 280 8C with a holding time of 10.5 min and injection volume of 2 mL [18]. A digital micropipette 10-100 mL (Volac) was used for transferring the sample solutions to the electrochemical cell.…”

“…chlorinated pesticides, polychlorinated biphenyls in the environment [1]. The determination of pesticides and herbicides in many environmental matrices is generally determined by SPE-LC-ESI-MS/MS [7], UPLC-MS/MS [8], HPLC [9], GC/MS [10,11] and LC-MS/MS [12] and polarographic [15,16] and voltammetric [17][18][19] methods. Recent years have seen an upsurge of interest for rapid and sensitive analyti-cal methods for the determination of chlorinated pesticides in environmental samples e.g.…”
