Potential of Napier millet, Pennisetum purpureum × P. glaucum, as a trap crop for managing Chilo partellus populations on maize
International Journal of Pest Management 58 (1), 1-7
Abstract: As a part of a habitat management strategy aimed at controlling Chilo partellus Swinhoe, Napier millet (Pennisetum purpureum × P. glaucum) was evaluated as a trap crop surrounding maize during 2008 and 2009 at Ludhiana, North India. Napier millet borders surrounding maize were compared to chemically protected maize and control maize plots for their effects on C. partellus oviposition, plant infestation and grain yield. Further experiments were carried out to determine whether adult experience could affect subsequent oviposition on test plants. Maize plots surrounded by Napier millet had fewer plants with borer eggs than control maize plots, although the results were significant only for the 2009 season. Percentage plant infestation and percentage dead hearts were less in Napier millet surrounded maize plots than in control maize plots during both seasons. Different treatments did not vary in terms of grain yield during the 2008 season, whereas maize plots surrounded by Napier millet had higher grain yield than control maize plots during the 2009 season. The preference of C. partellus females for Napier millet did not alter following experience with maize.
