ABSTRACT.
Tomato (Solanum lycopersicum L.) crops are affected by a diversity of pests. Among these pests, the whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) and the leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) cause large yield losses. The effects from these insects are often minimized by applying synthetic pesticides, although these have many drawback. To characterize novel tools for insect control, essential oils from two Asteraceae (Artemisia absinthium and Eupatorium buniifolium) were studied for their potential toxicity to beneficial insects [honey bees (Apis mellifera L.)] and phytotoxic effects against tomato seeds and vegetative parts. Our results show that seed germination was affected at application rates needed to control the leafminer T. absoluta but not at rates needed to control the whitefly T. vaporariorum. The same trend was found for honeybee toxicity: the use of these essential oils at the amounts needed to control T. vaporariorum would be not acutely toxic for bees. Finally, an experimental greenhouse trial showed that the application of the essential oil from E. buniifolium at 3% on whitefly-infested plants can cause whitefly adult mortality without affecting the crop yield.
