There are mealybug species that spend most of their time in the soil where they may feed on plant roots. This method of control is also more environmentally friendly than chemical treatments on the soil. The efficacy of commercially available chemical insecticides and biopesticides on the cotton mealybug (CMB), Phenacoccus solenopsis, was evaluated in the glasshouse.Spirotetramat, sulfoxaflor and buprofezin were identified as key insecticides for use in integrated pest management (IPM) strategies aimed at controlling CMB without flaring other co‐occurring pests.

Thereafter the mealybug larvae will move to another part of the same host plant until they develop into an adult, which takes around 4 to 8 weeks. This feeding habit increases the difficulty of control efforts using conventional spray insecticides. The highest mortality (78%) was observed in plants treated with 10 L ha ‑1 surpassing (P=0.0252) the control achieved with 4, 6 and 8 L. Since the mortality in the untreated control was so low (2%), the efficacy on mealybug control was close to the mortality rate. Soap sprays and oil sprays can also help control mealybugs without the disruption that can be caused by toxic chemical sprays.
