Extract

Gravid females of the red locust, Nomadacris septemlasciata (Serv.), were initially influenced by the microclimate in the selection of oviposition sites, and a laboratory investigation showed that females preferred to lay in well-illuminated areas with a soil temperature between 43 and 37°C., and avoided areas of very high surface humidity. Final acceptance of the soil took place only after the locust had probed with its ovipositor, and experiments demonstrated that particle size, compaction, moisture content and chemical composition of the soil all influenced the choice of oviposition site, while pH did not.
