- Abstract
Under the conditions of climatic warming, the long-term research at SCDA Turda (2006-2015) revealed that the main insect pests of wheat, represented by thrips, wheat flies, aphids, leafhoppers, wheat fleas and cereal leaf beetle, etc. have reached higher numerical potential in soil conservative no tillage crops than in conventional plowing crops. The paper states that these differences have increased in recent years (2015-2018) by increasing the share of pest groups in no-tillage winter wheat crops. Also, the pest attack has increased, reaching dangerous values with potential to compromise production, in the spring of 2018-2019, especially in aphids, leafhoppers, wheat flies and fleas. The populations of aphids and leafhoppers have caused the outbreaks of yellow dwarf viruses and mycoplasma in the case of early winter wheat sowing in the 2018-2019 vegetation year. The reported situation requires the planning and application of an integrated pest management (IPM) system under these conditions. IPM in this case and in the current situation of the biological and attack potential of wheat pests begins with the agro-technical methods, destruction of volunteers and the optimal sowing period especially, the insecticide seed treatment, and the insecticides treatments at two optimal spring-time moments (at the end of tilling and at the bellows phenophase - beginning of ears appearance) plus a continuous check on the occurrence and dynamics of insect pests for insecticidal warning interventions in case of attack caused by unexpected population explosions.
