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 کاملPotential for Modifying the Behavior of the Multicolored Asian Lady Beetle (Coleoptera: Coccinellidae) with Plant-Derived Natural Products
Bioassays were conducted to study the effectiveness of selected chemicals to prevent the multicolored Asian lady beetle, Harmonia axyridis (Pallas), from overwintering in buildings. We discovered that certain monoterpenoids elicited avoidance in adults toward treated Þlter paper within a petri dish bioassay at 1.0 mg/cm. Camphor and menthol were the most effective of the monoterpenoids tested. ...
متن کاملPredation by adult and larval lady beetles (Coleoptera: Coccinellidae) on initial contact with lady beetle eggs.
Naïve adults and larvae of the native lady beetles Coleomegilla maculata (DeGeer), Cycloneda munda (Say), Hippodamia convergens Guérin-Méneville, Olla v-nigrum (Mulsant), and the exotic lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were tested for their initial response to eggs of these five lady beetle species and for egg consumption on first contact and after 3 h. Additio...
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 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...
