In which regions is the Comstock mealybug found in the United States?

only in the state of CA
in the state of CA and several states in the eastern part of the US
only in the citrus producing states of the US
in a group of midwestern states

The correct answer is: in the state of CA and several states in the eastern part of the US

The Comstock mealybug is indeed found in California as well as in several states in the eastern United States. This pest is particularly prevalent in regions with climates conducive to its survival and reproduction, which includes both coastal areas and warmer inland regions. This distribution is significant because it highlights the impact of climate and host availability on pest populations. The Comstock mealybug has been observed in various agricultural settings where hosts such as grapevines and fruit trees are prevalent, which are common in both California and certain eastern states. The other options are too restrictive or inaccurate regarding the geographical spread of the Comstock mealybug, as they limit its presence to one state or specific regions that do not encompass the range where this pest has been documented. Understanding the distribution of such pests is crucial for effective pest management and regulatory measures.
