The distributions of Chilo partellus eggs per plant and larvae per plant in sorghum were found to be very different. Dispersal of larvae was believed to account for much of this difference. Measurement of dispersal in the 24 h after hatching revealed that 50–80 % of larvae dispersed from young plants, the extent of dispersal depending on the plant's age and on the cultivar grown. The differences in level of dispersal from different cultivars could be important in a resistance breeding programme and merit further investigation. Zusammenfassung Verbreitung frisch geschlüpfter Larven von Chilo partellus (Swinhoe) auf Sorghum‐Pflanzen Vergleichsuntersuchungen zeigten, daß die Verteilung der Eier von Chilo partellus an Sorghum ‐Pflanzen sich von der Verteilung der Raupen unterschied. Innerhalb von 24 Stunden nach dem Schlüpfen entfernten sich 50–80% der Eiraupen von den Eiablage‐Pflanzen, wobei die Wande‐rung vom Pflanzenalter und von Sorteneigenschaften abhing. Somit können diese Unterschiede für eine resistente Züchtung wichtig sein und verdienen weitere Untersuchungen.
