Hellemans, A., & Goossens, F. 2000 Bestrijding van gewone dopluis (Parthenolecanium pomeranicum) op Taxus. [Control of common scale (Parthenolecanium pomeranicum) on Taxus.]. Verbondsnieuws 44(19): 27-29.

Notes: Studies were carried out in 1998 in Belgium to compare the efficacy of Mitac (200 g amitraz/litre), Deltanet 400 EC (400 g furathiocarb/litre), Confidor 200 SL (200 g imidacloprid/litre), Applaud (250 g buprofezin/litre), and Karate 25 WG (2.5% lambda-cyhalothrin) for the control of P. pomeranicum on 7- and 8-year-old T. baccata. Treatments were carried during the last larval stage (22 and 29 April 1998) and after ova budding (29 June and 8 July 1998). The most effective insecticides for the first period (last larval stage) were Mitac, Deltanet and Confidor, and Mitac, Deltanet and Karate for the 2nd period.
