The LD50 of dimethoate was 1.9 g larva-1 48 h after oral exposure of larvae at day 4. Additional do-related effects on pupal mortality were noted.
After a chronic intoxication, the NOAEC (No Obrved Adver Effect Concentration) for larval mortality at day 7 was 2.5 mg kg-1, whereas a NOAEC of 5 mg kg-1 was
found at day 22 for delayed effects on the reduction of adult emergence.
