Abstract

In 2002, we evaluated the performance of imidacloprid-treated spheres topped by newly developed, rodent-protected, sugar/paraffin discs (that released sugar as needed, feeding stimulant onto the sphere surface) against apple maggot flies, Rhagoletis pomonella (Walsh). Commercial orchard plots (30 m × 30 m) surrounded by odor-baited, imidacloprid-treated, plastic spheres topped by 150-g discs (not replaced during the 12-week period of deployment) received no more immigrant adults or fruit injury than plots surrounded by odor-baited, imidacloprid-treated, wooden spheres topped by 50-g discs (replaced after 6 weeks), plots surrounded by odor-baited sticky-coated spheres, or plots sprayed two or three times with insecticide to control this insect. Approximately half of all apple maggot flies placed on imidacloprid-treated spheres not receiving additional sugar following retrieval from the plots died following exposure to spheres in the laboratory, irrespective of field-exposure duration (6, 9, or 12 weeks). Nearly all flies died when placed on orchard-exposed spheres that did receive additional sugar following retrieval. Future studies will aim at refining disc construction to ensure that all apple maggot flies alighting on imidacloprid-treated spheres will encounter feeding stimulant and be killed.

Résumé

En 2000, nous avons évalué la performance de sphères traitées à l'imidaclopride et recouvertes de disques de sucre/paraffine, nouvellement conçus et protégés contre les rongeurs, dans la lutte contre la mouche de la pomme, Rhagoletis pomonella (Walsh); les disques libèrent autant de sucre que nécessaire sur la surface de la sphère comme stimulant alimentaire. Des parcelles de vergers commerciaux (30 m × 30 m) entourées de sphères de plastique à appât odoriférant, traitées à l'imidaclopride et couvertes de disques de 150 g (non remplacés pendant les 12 semaines de l'expérience) n'ont pas reçu plus d'adultes immigrants, ni subi plus de dommage aux fruits que des parcelles entourées de sphères de bois à appât odoriférant, traitées à l'imidaclopride et couvertes de disques de 50 g (remplacés au bout de 6 semaines), ou des parcelles entourées de sphères à appât odoriférant couvertes de glu, ou encore des parcelles arrosées 2 ou 3 fois pour la lutte contre cet insecte. Environ la moitié des mouches placées sur des sphères traitées à imida clopride, sans avoir reçu de sucre après leur retrait des parcelles, sont mortes après avoir été exposées à des sphères au laboratoire, quelle que soit la durée de l'exposition de la sphère dans les vergers (6, 9 ou 12 semaines). Presque toutes les mouches placées sur des sphères exposées dans les vergers qui ont reçu du sucre additionnel après leur retrait du verger sont mortes. Les travaux futurs viseront à raffiner la construction des disques pour assurer que toutes les mouches qui se posent sur les sphères traitées à l'imidaclopride soient mises en présence du stimulant alimentaire et qu'elles soient éliminées.
