Field Identification
A small jumping plant-louse that feeds on citrus flush and is the vector of the bacterium causing huanglongbing (HLB). Adults tilt their bodies when disturbed; nymphs produce waxy tubules on tender growth.
Brownish adult about 3–4 mm, feeds with head down at a 45° angle. Yellow-orange nymphs on new growth; feeding causes twisted tips (psyllid burn).
How to Deal With It
Organic Control Methods
Do not move uncertified citrus material; scout flush weekly; in HLB areas, follow regional quarantine and removal guidance for infected trees.
Conserve Tamarixia radiata and Diaphorencyrtus aligarhensis parasitoids and generalist predators; flowering insectaries near groves support biocontrol.
Avoid synchronized heavy flushes when possible; reflective mulches and pruning strategies are sometimes used experimentally to alter psyllid landing.
Fine mesh on container citrus excludes adults; sticky traps monitor populations.
Oils, soaps, neem, or pyrethrin (botanical) may knock down adults with good coverage; none replace area-wide IPM—timing to flush protects beneficials as much as possible.
