Table 1

Mean percent survival, days to pupation, pupal weight, and relative growth rate with standard error of P. rapae (both sexes) between four host plants ( per treatment). Different letters indicate significant differences ().

A. petiolata rosette	56.25	15.33 ± 0.85	0.128 ± 0.003	0.277 ± 0.046
A. petiolata flowering	20.00	15.33 ± 1.45	0.112 ± 0.008	0.182 ± 0.031
B. oleracea “cabbage”	68.75	16.63 ± 0.28	0.134 ± 0.004	0.294 ± 0.019
B. juncea “mustard”	56.25	12.78 ± 0.46	0.132 ± 0.006	0.380 ± 0.044
