Many calls we are receiving about spittlebugs in pecan orchards at this time. It is easy to spot the immature stage of the insect which creates a ‘spittle’ mass to protect themselves from enemy insects and also from drying out. This insect is listed as a pest of pecan in our Southeastern Pecan Grower’s Handbook. The good news is that it is rarely ever a problem. It is better to ignore them.
Some growers have observed nuts aborting recently. We are still seeing general physiological nut drop right now, which is unrelated to the spittlebugs. If you feel like you have to do something for them, imidacloprid is recommended.
