The effects of ivermectin in ingested cow-dung on the mortality and oviposition of the dung fly Neomyia cornicina (Diptera: Muscidae)

Adults of the dung fly Neomyia cornicina (Fabricius) (Diptera: Muscidae) were allowed to feed on cattle dung containing known quantities of ivermectin for a single period of 24 hours. The concentrations required to kill 50% and 95% of the population, within one week of feeding, were calculated to be...

Description
Summary:Adults of the dung fly Neomyia cornicina (Fabricius) (Diptera: Muscidae) were allowed to feed on cattle dung containing known quantities of ivermectin for a single period of 24 hours. The concentrations required to kill 50% and 95% of the population, within one week of feeding, were calculated to be 0.139 and 0.393 μg/g (wet weight), respectively. Ingested ivermectin was found to reduce significantly the proportion of females ovipositing and delay significantly the onset of first oviposition. For those females which did oviposit, there was no effect of ivermectin ingestion on the number of eggs laid, but the eggs of females fed dung containing ivermectin at 0.15 μg/g showed a significant reduction in percentage egg hatch.
