Morphology of eggs of Dioctophyme renale Goeze, 1782 (Nematoda: Dioctophymatidae) and influences of temperature on development of first-stage larvae in the eggs

this study aims to provide information on morphological data of d. renale eggs, as well as on first-stage larvae development into eggs kept at different temperatures. eggs were obtained by centrifugation of infected dog urine, placed in petri dishes, and stored in bod chamber for a 90-day period. each treatment (gi - 15 oc, gii - 20 oc, and giii - 26 oc) was repeated five times. eggs showed average measures of 67.23 x 42.78 μm, and the mean incubation time was inversely proportional to the incubation temperature. larvae motility was observed one week after being observed in eggs.
