Population Growth of Heliothis armigera Hbn, on Suntlower

Life table is a concise summary of certain vital statistics of insect popula-tion. It is a useful technique in the study of population dynamics, provides a format for recording and accounting for all population changes in the life cycle of a species. The objective of the present study was to collect information for the construction of the life tables under laboratory condition, when the larvae of Heliothis armigera, a polyphagous and destructive pest causing heavy losses to many important crops were reared on sunflower heads. Life tables for this pest has been studied by other workers on lucerne (Billapate et al., 19/7) lima bean (Bilapate et al., 1978) and pea pods (Bilapate and Pawar, 1978)
