Repellent effects of different products of the neem tree on the Red locust, Nomadacris septemfasciata Serv., in maize fields in the southwestern parts of Madagascar

Abstract: The repellent effect of 3 different neem formulations was tested on red locust, Nomadacris septemfasciata Serv., in a maize field in the southwest of Madagascar. A simple water extract from neem seed kernels (200 l and 600 l per ha), an enriched neem ULV-formulation (2 l per ha) and a dust, prepared on the base of neem seed cake (5 kg per ha) were applied. All four treatments provided protection from attack for at least five days. The water extract was significantly active until 7 days, the neem-ULV-formulation until 9 days after treatment. The application of neem seed kernel water extract could be a simple means for Malagasy farmers to protect their fields against red locust.
N. septemfaciata is a very interesting test organism because it is much easier to work with this species compared to the taxonomical closely related desert locust (Schistocerca gregaria Forsk.).
