By targeting Asian citrus psyllids on an area-wide scale and focusing on several individual properties simultaneously, growers can minimize psyllid movement between groves, reduce HLB transmission and maintain citrus production at a profitable level. Generally, most psyllid sprays are applied on a calendar or threshold basis, resulting in high-spray frequencies and associated costs. Because of the Asian citrus psyllid’s high …
Biological Control of the Asian Citrus Psyllid
Managing the Asian citrus psyllid (ACP) is critical because of its role in spreading huanglongbing (HLB). Biological control is one method for ACP control. It is essential for developing integrated and sustainable pest management strategies. Biological control has always been a vital component of citrus pest management in Florida; understanding its contribution to the mortality of ACP is crucial. Despite …
ACP Monitoring Efforts in Georgia
The citrus industry is expanding in Georgia. With that growth comes the need to slow the spread of the Asian citrus psyllid (ACP), the vector of HLB disease. Although not yet found in Georgia’s commercial citrus production, there have been confirmed HLB-positive residential citrus trees. The disease has the potential to greatly hinder the state’s citrus industry. Therefore, the University of …
Dormant Sprays for Asian Citrus Psyllid Management
Several studies have documented the positive effects of controlling the Asian citrus psyllid (ACP, Figure 1) for citrus tree health and sustainability in Florida. The mature blocks established before and after the discovery of huanglongbing (HLB) in 2005 continue to benefit from psyllid control. One psyllid is enough to infect a tree with HLB for life, and repeated infestations negatively …
