Abstract

Several horticultural oils, an insecticidal soap, neem, garlic extract, a sugar ester, and a synthetic insect growth regulator were evaluated under laboratory conditions for their ability to inhibit pear psylla’s [Cacopsylla pyricola (Foerster)] feeding and oviposition. Supreme oil significantly reduced winterform oviposition rates in both choice and no-choice assays and reduced feeding rates in no-choice assays. Supreme oil also reduced oviposition rates of summerform females in choice tests but not in no-choice tests. In addition, summerform oviposition rates were reduced significantly by application of several mineral oils (Orchex 796E, 692, and WS2928) and garlic barrier to pear foliage in no-choice tests, and by all oils, garlic barrier, and M-Pede in choice tests. Summerform feeding rates were reduced by application of mineral oils. Data suggest that "summer type" oils and other compounds may have utility in pear psylla management programs by decreasing feeding and oviposition.

Résumé

Différentes huiles horticoles, un savon insecticide, de l’extrait de margousier, de l’extrait d’ail, un ester de sucre et un régulateur synthétique de croissance d’insecte ont été testés en laboratoire de façon à permettre l’évaluation de leur capacité d’enrayer l’alimentation et la ponte chez la Psylle du poirier [Cacopsylla pyricola (Foester)]. L’huile «Supreme» réduit significativement les taux de ponte chez les femelles d’hiver, aussi bien dans les expériences avec choix que dans les expériences sans choix, et réduit les taux d’alimentation dans les expériences sans choix. Cette huile réduit également les taux de ponte chez les femelles d’été, mais seulement au cours des expériences avec choix. De plus, les taux de ponte des femelles d’été ont été réduits significativement à la suite de l’application de plusieurs huiles minérales (Orchex 796E, 692 et WS2928) ou d’une couche d’extrait d’ail au feuillage des poiriers dans les expériences sans choix; toutes les huiles, la couche d’ail et le M-Pede ont entraîné des réductions dans les tests avec choix. Les taux d’alimentation chez la forme d’été ont été réduits par l’application d’huiles minérales. Les données semblent indiquer que les huiles «de type été», et d’autres substances également, pourraient s’avérer utiles dans les programmes de lutte contre la Psylle du poirier en en réduisant l’alimentation et la ponte.
