Citrus greening disease is seriously hindering citrus production in the United States, but generating widespread adoption of the best integrated pest management practices among growers is a challenge, especially when livelihoods are on the line. Recognizing the strong economic factors at play in management decisions will help improve plans for increasing IPM adoption.
In many areas where the Asian citrus psyllid spreads citrus greening disease to commercial groves, it can evade control efforts by infesting residential citrus trees. A new attract-and-kill device, however, is being evaluated for managing psyllids on citrus in residential areas.
Tracking the movements of the diminutive pests is a challenge, but a new study shows that DNA analysis of psyllid gut contents can reveal what plants psyllids have fed on, thereby pinpointing the non-crop "whistle stops" psyllids make before infesting crop fields.
Sticky traps used to monitor orchards for the Asian citrus psyllid often catch an array of larger non-target organisms. But a thin layer of mesh fabric—the same kind used in bridal veils and ballet tutus—makes an effective screen to eliminate most bycatch while still catching the target pests.
