Mamadou Sétamou, Ph.D., is professor of citrus entomology at the Texas A&M University Kingsville Citrus Center. He says sticky traps for monitoring for the Asian citrus psyllid (Diaphorina citri) in orchards often catch other insects such as lady beetles or lacewings, and even lizards and birds. Looking to reduce such bycatch, Sétamou and colleagues turned to a simple solution: tulle mesh fabric, which acts like a sieve, allowing psyllids to pass through to the sticky trap but keeping larger nontarget organisms out.
