Methiocarb-d3 is intended for use as an internal standard for the quantification of methiocarb (Item No. 25627) by GC- or LC-MS. Methiocarb is a carbamate pesticide with insecticidal, molluscicidal, acaricidal, and bird repellant properties.{43317,43318,43319,43320,43323} It inhibits acetylcholinesterase (AChE) activity and is toxic to the western flower thrip (F. occidentalis; IC50 = 2.1 ?M; LC50 = 3.26 ppm).{43318} Methiocarb is also toxic to the land snail M. obstructa (LD50 = 27.4 ?g/snail) and the citrus mite A. pelekassi, inducing 94% mortality when used at a concentration of 0.5 ppm.{43317,43319} It reduces the seasonal percentages of cotton bolls infested with pink bollworm (P. gossypiella) to 4%, compared with 65% infestation in untreated controls, when applied to cotton fields at a concentration of 1.86 lb/acre.{43323} Methiocarb reduces damage to grapes by song birds when applied to vineyards at a concentration of 2.5 lbs AI per 100 gal water per acre.{43320} It is an estrogen receptor ? (ER?) and ER? agonist (EC20s = 19.87 and 20.24 ?M, respectively) and an androgen receptor antagonist (IC50 = 13.89 ?M) in cell-based reporter assays.{43321} It is toxic to juvenile rainbow trout (O. mykiss) and guppies (P. reticulata) with LC50 values of 0.8 and 1.48 mg/L, respectively, at 48 hours of exposure.{43322} Formulations containing methiocarb have been used in the agricultural control of pests.
