Studies of the effect of allelochemicals or other insect growth regulator on the development of insect are difficult using parameter currently employed. By measuring the effect growth-inhibiting of seed crude extract of : Annona muricata; Azadirachta indica; and leaf crude extract of Lantana camara on the Heliothis armigera larvae, growth index (GI) and relative growth index (RGI) calculation are demonstrated in this paper.

Index term: Growth Index, Relative Growth Index, Annona muricata, Azadirachta indica, Lantana camara, Heliothis armigera.
