3.3. Life table parameters
It was observed that the intrinsic rates of increase of P. xylostella
differed significantly on the eight host plants (F ¼ 5.82; df ¼ 7, 185;
P < 0.0001) (Table 3), and the rm on canola (rm ¼ 0.2753) was the
highest, and that on cabbage (rm ¼ 0.1666) was the lowest. Simi-
larly, the finite rates of increase of P. xylostella were significantly
