August 2012. Haiti is reporting an agricultural emergency following the infestation of Crypticeryagenistae (soybeanscale), an invasive scaleinsect (Hemiptera:Margarodidae) that is destroying crops in the northeast of thecountry (affecting 10,000 ha so far). It is of concern that this outbreak could have a large food security and economic impact in the region with the risk of spreading throughout the country.
Are there any biopesticides/biocontrol agents known that provedsuccessful for Crypticerya genistaescale control?
In response, a member from the Ministry of Agriculture, Barbados, said that ladybird beetle Anovia circumclusa(Coleoptera: Coccinellidae) gives excellent control ofthis scale. There is also a parasitic Phorid fly (found in Florida) that can give additional biocontrol. Both provide sustainable long term control. A. circumclusahas worked well in Barbados.
