Pine oil (Norpine-65, Northwest Petrochemicals) was assessed as an oviposition deterrent for gravid female onion maggots, Delia antiqua (Meigen), in two types of laboratory experiments. When given a choice for 24 h between a control onion half treated with hexane and an onion half treated with pine oil in hexane, the females oviposited preferentially on or around the control onion half. In a no-choice experiment the females laid over three times as many eggs on or around solvent control onions as on or around onions treated with 1.0% pine oil. The DC50 (deterrent concentration50) was calculated to be 0.09%. The results suggest that pine oil (or its constituents) may have potential as an oviposition deterrent under field conditions.

L’huile de pin (Norpine-65, Northwest Petrochemicals) a été testée comme inhibiteur de la ponte chez des femelles gravides de la mouche de l’oignon, Delia antiqua (Meigen), par deux types d’expériences. En présence pendant 24 h d’un choix entre une moitié d’oignon témoin traitée à l’hexane et une moitié traitée avec l’huile de pin, les femelles ont pondu préférentiellement sur ou autour de la moitié témoin. Dans une situation n’offrant pas de choix, les femelles ont pondu plus de trois fois plus d’oeufs sur ou autour des moitiés d’oignon traitées à l’hexane, que sur ou autour de celles traitées avec l’huile de pin à 1,0%. La DC50 (concentration répulsive médiane) a été estimée à 0,09%. Les résultats indiquent que l’huile de pin (ou certains de ses constituants) est peut-être utilisable pour inhiber la ponte dans certaines conditions sur le terrain.
