Displaying 1 - 6 of 6 datapoints.
Species: Mallard duck (Anas platyrhynchos)
Chemical Toxicity Endpoint Type Endpoint Description Endpoint Value Sample Size Life Cycle Stage Study Duration Type
METHYLPARATHION TOX-REPRO - reproductive success number of eggs per incubated nest and percent fertility of eggs compared with controls no effect 12 pairs/group Adult until ducklings were 5 d old Toxicity Factor Datasets
METHYLPARATHION TOX-REPRO - physiology proportion of hens laying and number of eggs laid per hen compared to controls decreased if treatment initiated during egg laying 12 pairs /group Adult until ducklings were 5 d old Toxicity Factor Datasets
METHYLPARATHION TOX-MORT - dose-response data incidence of adult mortality during incubation compared with controls 2/12 when treatment initiated during early incub.; 2/11 when treatment initiated during late incub. 12 pairs/group Adult until ducklings were 5 d old Toxicity Factor Datasets
METHYLPARATHION TOX-Non-Repro-Sublethal - behavioral effects incidence of nest abandonment compared with controls increased when treatment initiated during early or late incub. 12 pairs/group Adult until ducklings were 5 d old Toxicity Factor Datasets
METHYLPARATHION TOX-REPRO - reproductive success number of hatchlings per nest, percent hatchability, hatchling survival and body weight to 5 days compared with controls no effect 12 pairs/group Hatchling until ducklings were 5 d old Toxicity Factor Datasets
METHYLPARATHION TOX-Non-Repro-Sublethal - behavioral effects food consumption compared with controls decreased when treatment initiated during laying, early or late incub. 12 pairs/group Adult until ducklings were 5 d old Toxicity Factor Datasets
