Evaluation of acylurea insecticides for the control of stigmella malella

, : Evaluation of acylurea insecticides for the control of stigmella malella. Fruit Science Reports (Skierniewice) 12(3): 121-126

Diflubenzuron, triflumuron and CME 134 appeared to be most effective for the control of Stigmella malella applied both before egg laying as well as during the initial stages of caterpillars feeding in the mines. An insecticide CGA 112913 was also effective when applied before and after egg laying or at the beginning of caterpillar hatching. Cyromazine was less effective. Applied at the same time as CGA 112913 caused the death of caterpillars but somewhat later than other insecticides. None of the investigated insecticides applied at the recommended concentrations appeared to be an effective ovicide.
