Bionomics and economic meaning of brassica pod midge (Dasineura brassicae Winn.) in new technologies of winter rape cultivation

Original language description

Brassica pod midge (Dasineura brassicae (Winnertz)) now belongs to the most serious pests of winter rape in the Czech Republic. In the years 2002 ? 2004 field small-plot trials were established on several locations ? Prague, Uhříněves, Humpolec, Opava and Nechanice. The study was aimed at explaining bionomics, economic meaning and protection against this pest. Harmful presence of adult midges was found from the beginning of May to the half of June. Ovipositing was observed repeatedly from up to 5 cm long pods without mechanical damage. The best results in protection were obtained with application of preparations in the time of finishing blossoming or even later. In this period efficient substances in system preparations affect the larvae. When pyretroids were applied in the time of flowering, they were found as inefficient. The effect of time of treatment is statistically significant on the number of damaged pods as well as on the yield. The best variant of protection increased the yie
