Multicolored Asian lady beetle (Coleoptera: Coccinellidae) activity and wine grape phenology: implications for pest management.
We determined the phenology of the multicolored Asian lady beetle, Harmonia axyridis (Pallas), adults in relation to the phenology of wine grapes (Frontenac and Marechal Foch) in Minnesota and Wisconsin vineyards to establish a management window for H. axyridis infestations in wine grapes. In addition, we also assessed the flight activity of H. axyridis in an agricultural landscape. The phenolo...
متن کاملA Simple Method for In-Field Sex Determination of the Multicolored Asian Lady Beetle Harmonia axyridis
The multicolored Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), has become a popular study organism due to its promise as a biological control agent and its potential adverse, non-target impacts. Behavioral and ecological research on H. axyridis, including examinations of its impacts, could benefit from non-destructive or non-disruptive sexing techniques for this coc...
متن کاملEfficient synthesis of (R)-harmonine--the toxic principle of the multicolored Asian lady beetle (Harmonia axyridis).
A flexible synthetic route to (R)-harmonine ((R)-1), the toxic principle of the Asian lady beetle Harmonia axyridis (H. axyridis), via reductive olefination of the macrocyclic lactone (S)-5, is reported. High enantiomeric purity is achieved by enantioselective saponification of the lactone rac-5 with horse liver esterase. Minor modifications in the synthetic route give access to racemic and chi...
متن کاملInteractions between the Multicolored Asian Lady Beetle Harmonia axyridis and the Parasitoid Dinocampus coccinellae
Harmonia axyridis (Pallas) has been introduced either intentionally or accidentally in different areas outside its native range, where it is often regarded as invasive. Dinocampus coccinellae (Schrank) has been recorded to parasitize H. axyridis in the field, both in the native and introduced areas, Italy included. The percent of parasitism found in our field investigation was low (four percent...
متن کاملWine Grapes in the Midwest: Reducing the Risk of the Multicolored Asian Lady Beetle
Wine grape production has increased significantly in Minnesota and other Midwestern states during the past 20 years. Even though the acreage of Minnesota grapes is low (about 220 ac.), the high value of the crop, ranging from $4,000 to $7,000/ac, depending on the grape variety, has increased its importance in Minnesota and enhanced the diversity of agriculture and the economy. This growth in th...
