Abstract:An outbreak of Nysius raphanus Howard occurred in the San Joaquin Valley of California during the spring of 1959 and 1960. Population build-up occurred on Sisymbrium irio L., Capsella Bursa-pastoris (L.) Medic. and Lepidium nitidium Nutt. Migration to cotton occurred in mid-May, with resultant destruction of seedling plants. In field experiments endrin and heptachlor gave satisfactory control while Sevin® (1-naphthyl methylcarbamate) was relatively ineffective. In laboratory experiments using a bioassay vial method of exposure, the approximate micrograms of several toxicants needed to give 50% mortality were: malathion 0.0017, dieldrin 0.3, endrin 1.0, Dipterex® (dimethyl 2,2,2- trichloro-1-hydroxyethylphosphonate) 1.6, toxaphene 30, DDT 80, and Sevin 50. Laboratory results with Sevin were erratic and inconclusive.
