Insects have evolved resistance to Bt toxins in the laboratory, yet only one crop pest, the diamondback moth (Plutella xylostella), has evolved resistance to Bt toxins under open field conditions (Tabashnik et al. 2003). But this resistance was not caused by Bt crops, rather it occurred in response to repeated foliar sprays of Bt toxins to control this pest on conventional (non-GE) vegetable crops (Tabashnik 1994). Based partly on the experience with diamondback moth and because Bt crops cause season-long exposure of target insects to Bt toxins, some scientists predicted that pest resistance to Bt crops would occur in a few years.

Using 3rd instar larvae of the diamondback moth Plutella xylostella), the antifeedant and insecticidal activities of sixteen quassinoids were compared with those of known insect antifeedant chlorodimeform (= galecron), as shown in Table 16. The insecticidal activity of quassin (78) was higher than that of chlorodimeform, although its antifeedant activity was nearly identical to that of the reference compound [39]. 

These compounds were tested against a series of Lepidoptera including Plutella xylostella Px, diamondback moth), Hdiothis virescens Hv, tobacco budworm), and Spodopterafrugiperda (Sf, fall armyworm). Insecticidal activity is reported in Tables I-111 as percent plant protection at various concentrations where reduction in plant damage generally resulted from insect mortality rather than cessation of feeding.

While dieldrin target-site resistance (Section 29.5.2.2) can confer some level of resistance to fipronil, this cross-resistance has not led to failure of fipronil in the field. However, resistance due to other mechanisms was seen in southeast Asia as early as 1996 in diamondback moth Plutella xylostella), within three years of the introduction of the product. The high intrinsic activity of fipronil and lack of alternatives in the mid-1990s led growers in countries such as Thailand to use it up to 40 times per year on cruciferous crops. By early 1997, many populations were resistant and field failures were widespread. At the same time, use of the...

For the diamondback moth, Plutella xylostella (syn. A. maculipennis) (another crucifer-feeding insect), (2/ )-hy-droxy-3-butenylglucosinolate (progoitrin) (21) was more effective than other glucosinolates in inducing feeding on artificial diets. 

The host range of the diamondback moth, Plutella xylos-tella, appears to be correlated with the presence of glucosinolates in the host plants, but the role of stimulants and attrac-tants in oviposition seem to be important. Extracts of Brassica oleracea (cabbage), B.juncea (mustard), and Erysimum cheiranthoides stimulated oviposition by gravid females on bean plants. Extracts of Erysimum cheiranthoides, Tropaeolum majus, and Capsella bursa-pastoris which deterred oviposition by the cabbage butterfly Pieris rapae, were not deterrent to Plutella xylostella (Renwick and Radke, 1990).
