Abstract:Experiments were performed in 1975, 1976, and 1977, for control of larvae and needle mining of Coleotechnites near milleri (Busck) in southern California by utilizing 19 insecticides and 3 application methods. Needle acephate residues were recorded and interpreted for 1976 and 1977 experiments. Acephate sprays and trunk implants were very effective against larvae; dimethoate implants were effective against larvae. Acephate spray residues degraded rapidly initially, whereas solution implant residues increased rapidly, and Medicap® implant residues increased slowly. Increasing larval mortalities and implant residues suggested ca. 4 wk should elapse before acephate mortality determinations. Permethrin spray was very effective in preventing 1st-instar mines; resmethrin was ineffective; and against older larvae, sprays of Pydrin® (benzeneacetic acid, 4-chloro-alpha-(1-methylethyl)-, cyano(3-phenoxyphenyl) methyl ester) or Decis® (S-alpha-cyano-3-phenoxybenzyl d-cis-3-(2,2-dibromovinyl)- 2,2-dimethyleyclopropanecarboxylate) were effective. Phosmet spray was effective in preventing 1st-instar mines but ineffective against 4th instars. After 4 wk, malathion spray was less effective against 2nd and 3rd instars than acephate spray. Fenitrothion spray was effective against 4th instars.
