Fruit Bites July 7-9 Scales
AW: Scale insects can either be covered by a soft shell or a hard-armored shell. One example is the San Jose scale, commonly found in apple and pear orchards, and when feeding on fruit, can leave a small red spot. Higher populations feeding on twigs and limbs can cause tree decline or death.
BL: So, how do I find San Jose scale?
AW: From now until harvest, look for red spots on fruit. Scales hide in the crevices of the bark, so ensure thorough coverage and include a good horticultural oil.
But that’s not the only red, or mark scales have left. In the early 1500s when Spaniards arrived in Mexico, they saw the cochineal (KAA-CHUH-NEAL) scale being collected from prickly pear cacti and ground into the richest red powder used for dye; coveted by artists and royalty.
