Long-term dynamics density of populations of interspecific cereal aphids (homoptera, aphididae) throughout the growing season of winter wheat under steppes Ukraine
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2017, Vol 9, Issue 1
Abstract
Goal. Study features seasonal fluctuations in long-term dynamics of harmful insect herbivores state of development of interspecific populations of cereal aphids in winter wheat crops under steppes of Ukraine. Methods. Comparative, analytical, field, statistical and mathematical. Results. The results of long-term observations of the dynamics of the density of harmful insect herbivores cereal aphids in winter wheat crops. Determined that the highest density of pests in crops of winter wheat in 2016 was in the range of 6.0 to 17.0 copies per 1 plant in the spring and summer growing season crops, and in autumn the highest density was in 2016 at around 10, 0 - 50.0 copies per 100 strokes nets. Conclusions. Based on our own research suggested making timely monitoring of harmful insect herbivores cereal aphids to install and needs EPSH chemical crop protection from herbivores winter wheat. Proposals to make timely route inspection records pest density in two winter wheat growing season: spring, summer and autumn.
