38. Chemical analyses indicated that leaf damage by Pieris rapae caterpillars induced high concentrations of indole glucosinolates, whereas leaf damage by scissors alone did not induce indole glucosinolates [F(1,30) = 6.480, P = 0.016] (24). Setose trichomes were also found to be inducible (increase in density and total number) on newly formed leaves of previously damaged plants [F(1,36) = 10.208, P = 0.003] (6).
39. A total of 454 plants were divided into three treatments as follows: 151 induced plants, 150 leaf damage controls, and 153 overall (unmanipulated) controls. Half of the leaf damage control plants were clipped at the start of the treatments (that is, when caterpillars were placed on induced treatment plants), and the other half were clipped when the caterpillars on the induced treatments had finished consuming the leaf (3 to 4 days later). The research plot was located in a plowed old field at the University of California Student Experimental Farm (Davis, CA). Seeds were collected from several wild populations of R. sativus in Davis, and cotyledonary plants were transplanted from plug trays during the typical period of juvenile growth. The plot was not irrigated.

47. From the analysis of variance for the effect of treatments on abundance of ladybird predators, F(2,451) = 0.118, P = 0.889.
48. 2 test for the effect of flea beetles on plant mortality, G = 7.532, degrees of freedom = 2, P = 0.023.
49. In identical experiments performed on a sibling species (Raphanus raphanistrum) at a site in the Sierra Nevada foothills, I found similar results (6). In these experiments, induced responses to herbivory protected plants from herbivory by grasshoppers and lepidopteran larvae and increased flower production and seed set compared with control plants.
50. Overall effects of treatments on female plant fitness are significant [F(2,445) = 11.004, P < 0.001]: For the contrast of induced plants compared with overall controls, F(1,445) = 6.567, P = 0.011 ; and for the contrast of leaf damage controls compared with overall controls, F(1,445) = 4.954, P = 0.027.
51. From the analysis of variance on early season flower production, F(2,451) = 3.470, P = 0.032.

71. From the analysis of variance for the effects of experimental induction on (i) chewing herbivory and (ii) plant colonization by aphids measured on two sampling dates with multivariate analysis of variance, Wilks' lambda = 0.972, F(4,888) = 3.23, P = 0.012 for chewing herbivory; and Wilks' lambda = 0.956, F(4,876) = 4.985, P = 0.001 for plant colonization by aphids. Half-sib families also varied in their susceptibility to herbivory and attack by aphids [Wilks' lambda = 0.834, F(30,1694) = 2.625, P < 0.001].
