Many arthropod agricultural pests have become resistant to pesticides through inappropriate usage. A consequence of this resistance is often cross-resistance with other pesticides with similar or related modes of actions. As a result of increasing pesticide resistance, a movement to alternative, ‘green’ botanical pesticides has been growing. A new formulation of volatile oils, extracted from a variety of plants allows for slow-release and longer duration in the field. In this publication we present results of the efficacy of one of these products against the cotton aphid Aphis gossypii on cucumber plants in replicated choice tests. The slow release Ap2, a Bio-Pel product from Newseal Mineral and Coatings Ltd. (hereafter Newseal), significantly reduced the population of aphids on test plants and prevented their movement upwards on the plant. Additionally, four Newseal products caused no mortality to the aphid parasitoid Aphidius colemani or to the generalist predator, Orius laevigatus.
