AB  - BACKGROUND: Rape stem weevil (Ceutorhynchus napi Gyll.) and cabbage stem weevil (C.
pallidactylus Marsh.) can cause significant yield losses to oilseed rape (Brassica napus L.),
and chemical control is often needed to protect crops from these pests. The efficacy of six
insecticides, chlorpyriphos+cypermethrin, bifenthrin, alpha-cypermethrin, pirimiphos-methyl,
thiacloprid and tau-fluvalinate, was tested in a four year field trial. Besides the standard efficacy analysis expressed through the number of larvae per stem, a damage rating scale was
introduced and modelled using a regression model for ordinal categorical data.
RESULTS: Compared with the control, expressed through damage rating and larval number,
treatments with chlorpyriphos+cypermethrin and bifenthrin, showed higher efficacy in the
control of stem weevils compared to alpha-cypermethrin and pirimiphos-methyl. The lowest
efficacy was observed in treatments with tau-fluvalinate and thiacloprid.
CONCLUSION: This study showed that a combined efficacy evaluation expressed through
both damage rating scale and the count of larvae, supported by an ordinal regression model
for data analysis, is indispensable for obtaining accurate results.
