Mealybug Identification

How to Distinguish Among Different Mealybugs



Vine Mealybug Look-a-like

The solanum mealybug (Phenacoccus solani) occurs in Sonoma County and closely resembles the vine mealybug. This mealybug is generally found on the crown and roots of weeds. Malva (cheeseweed) is a common host in Sonoma County. The solanum mealybug has also been documented on a wide variety of plants throughout North America. Females give birth to live young and unlike vine mealybugs, no egg masses are present.
