Abstract

Spike washing and direct count methods were equally effective for sampling eggs and young larvae of millet spike worm, Raghuva albipunctella (Noctuidae: Lepidoptera) in Senegal, but spike washing is a more economical method. Most eggs (70%) were laid on emerging millet spikes and the spike apex was the preferred oviposition site. Most larvae pupated 10–30 cm from millet hills. The maximum number of pupae was found in the upper layer (< 10 cm) in loamy soil and deeper (20–30 cm) in sandy soil. Ploughing fields after millet harvest reduced the population of spike worm pupae significantly, but may prove impracticable or socially unacceptable to farmers
