“…Spittlebug management strategies must be used together so that the control of this pest is sustainable and efficient. Among the management strategies used in Brazil, we highlight the diversification of pastures [13], chemical control [14], biological control [15,16], and the use of resistant plants [17]. The use of insecticides and botanical repellents is a widespread strategy, and studies of this nature are necessary for the management of forage pests.…”

In this study, we evaluate the olfactory responses of Mahanarva spectabilis adults to aqueous extracts from the following non-host plants for the pest insect: garlic (Allium sativum L.), rue (Ruta graveolens L.), cinnamon (Cinnamomum verum J. Presl), lemongrass (Cymbopogon citratus Stapf.), clove (Syzygium aromaticum L.), star anise (Illicium verum Hook.f), eucalyptus (Eucalyptus globulus Labill.), tobacco (Nicotiana tabacum L.), and thyme (Thymus vulgaris L.) applied to the host plant, elephant grass (Pennisetum purpureum Schum.). The bioassays were performed using a Y olfactometer, and the combinations of the plant extracts applied to the host plant were tested against fresh air and against the host plant without the extract. The results show that the extracts of tobacco and star anise were non-attractive to M. spectabilis adults. The extracts from the remaining plants did not alter the response of M. spectabilis to the host plant.
