New soybean pest: Trochanter mealybug

Infestations of the trochanter mealybug (Pseudococcus sorghiellus, in the Order Hemiptera, Suborder Homoptera, Superfamily Coccoidea and Family Pseudococcidae), an unarmored scale insect, were first identified in Midwestern soybean crops in 2008.  They can be found on the roots of soybeans that appear to be suffering from potassium deficiency (yellowing of the leaves).
