Phillips, P.A., & Sherk, C.J. 1991 To control mealybugs, stop honeydew-seeking ants.. California Agriculture 45(2): 26-28.

Notes: Abstract: Recent increases in obscure mealybug (Pseudococcus affinis) infestations in central-coast vineyards have been associated with Argentine ant (Iridomyrmex humilis) activity. Infestations were reduced by controlling these honeydew-seeking ants in the spring, using chemical treatments directed at the base of the vines. This control strategy avoids full coverage treatments disruptive to beneficials. Keywords: biological control.
