Efficacy of Ground ULV Application of NyGuard (10% Pyriproxyfen) Against Aedes albopictus Larvae in St. Augustine, Florida
Abstract
Semi-field experiments were conducted on the efficacy of ground ultra-low volume (ULV) application of NyGuard Concentrate (10% pyriproxyfen) on adult emergence of Ae. albopictus larvae exposed as late third and early fourth instar. Direct contact was evaluated by direct exposure of pyriproxyfen to larvae in water collected when ULV conducted in the streets. Indirect contact was evaluated by removing treated vegetation from the streets and soaking the leaves in water for 24 hours before adding larvae in the laboratory. Both experiments indicated that ground ULV of NyGuard (10% pyriproxyfen) exhibited adult emergence inhibition > 85%. Operationally, these results suggest that ground ULV application of 10% pyriproxyfen would suitably inhibit adult emergence of Ae. albopictus. We recommend that further testing be conducted so that this insect growth regulator can be labeled for area-wide ULV application as a larvicide.
