Tacoli, F., Bell, V.A., Cargnus, E., & Pavan, F. 2018 Insecticidal activity of natural products against vineyard mealybugs (Hemiptera: Pseudococcidae). Crop Protection 111: 50–57
Notes: Laboratory experiments and field trials were conducted in New Zealand in 2015–16 on Pseudococcus calceolariae (Maskell) and Pseudococcus longispinusPlanococcus ficus (Signoret) to assess the insecticidal activity of kaolin and citrus essential oil. Although kaolin increased Ps. calceolariae mortality in the laboratory, it was ineffective at controlling the three mealybug species in the vineyards. In contrast, citrus essential oil increased mortality of Ps. calceolariae and Pl. ficus in the laboratory and chereduced leaf infestations of the latter in the vineyards. Citrus essential oil could be a good alternative to synthetic insecticides against vineyard mealybugs.
