Breaking up ain't hard to do… if: Remove all affected leaves as soon as you see them. may!provide!on!an!annual!basis.! To maximize insecticide efficacy and leafminer control, synchronize pesticide applications with emergence of leafminer adults and new plant growth (Hoover 2001). Adult arborvitae leafminers (Argyresthia thuiella) appear starting around mid-June into July or 533-700 growing degree days. Although chemical control is an option on susceptible cultivars, there are also many boxwood varieties that have shown genetic resistance to Boxwood Leafminer. Larvae will turn into adults and break through the lower leaf surface when fully matured. Ageniaspis citricola (female and three pupae). Chemical Control Multiple chemicals and types of application offer leafminer control options. View the Current Distribution of Citrus Leafminer in California Consider treatment when there are over 250 pinholes per trifoliate (three leaves) or if 30-40% of leaflets contain pinholes.
