Update & Correction Concerning Collection Of Sugarcane Aphid In Kentucky Grain Sorghum

Aug 26, 2015

By Doug Johnson, Extension Entomologist, University of Kentucky.

This note is provided for clarification of where in Kentucky Sugarcane aphid has been collected and identified. The first two collections were reported as Fulton and Graves counties. This was incorrect it should have read Fulton and Calloway Counties, KY. The Calloway Co. infestation was reported by the Graves Co. Extension agent and I confused the location.

Since that report two further infestations in KY counties were confirmed. They are Lyon and Caldwell counties. To the best of my knowledge none of these infestations were at the economic threshold for control.

Though we are approaching maturity for most of our grain sorghum fields, it might be worthwhile in planning for next year to know how far north and east this insect has penetrated. If you have opportunity to check any sorghum fields (grain, sweet or forage) and find aphids, please feel free to send me a sample.

Video: Finding a Balance of Innovation and Regulation - Dr. Peter Facchini

Regulations help markets and industry exist on level playing fields, keeping consumers safe and innovation from going too far. However, incredibly strict regulations can stunt innovation and cause entire industries to wither away. Dr. Peter James Facchini brings his perspective on how existing regulations have slowed the advancement of medical developments within Canada. Given the international concern of opium poppy’s illicit potential, Health Canada must abide by this global policy. But with modern technology pushing the development of many pharmaceuticals to being grown via fermentation, is it time to reconsider the rules?

Dr. Peter James Facchini leads research into the metabolic biochemistry in opium poppy at the University of Calgary. For more than 30 years, his work has contributed to the increased availability of benzylisoquinoline alkaloid biosynthetic genes to assist in the creation of morphine for pharmaceutical use. Dr. Facchini completed his B.Sc. and Ph.D. in Biological Sciences at the University of Toronto before completing Postdoctoral Fellowships in Biochemistry at the University of Kentucky in 1992 & Université de Montréal in 1995.
