Performance of entomopathogenic nematodes on the mealybug, (Hemiptera: Pseudococcidae) and the compatibility of control agents with nematodes.

The performance of nine isolates of and one of on the mealybug (Hemiptera: Pseudococcidae), were evaluated. The most virulent isolates were evaluated for nematode vertical and horizontal dispersal, and for efficiency at concentrations of 0 (control), 25, 50, 75, and 100 infective juveniles (IJs)/cm on adult females of the insect. A compatibility assessment was also carried out with commercial products, registered or in the process of registration, for use in the cassava culture.
