Plutella diamondback moth

An example of a larval parasitoid that responds to the host sex pheromone is seen with Cotesiaplutellae (Braconidae), also a parasitoid of the diamondback moth. These insects were attracted equally to the pheromone blend (31,32,33, see above), the acetate 32, or aldehyde 31 components [80]. This larval parasitoid, however, was also strongly attracted to host frass volatiles, in particular, dipropyl disulfide 34, dimethyl disulfide 35, allyl isothiocyanate 36, and dimethyl trisulfide 37. In contrast, the egg parasitoid Trichogramma chilonis was only weakly attracted to 36. In both, T. chilonis and C. plutellae, plant volatiles, in particular (3Z)-hex-3-en-l-yl acetate 38, significantly enhanced attraction by the pheromone [80].

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. 

Essential oils from laurel were evaluated for fumigant toxicity against all developmental stages of the confused flour beetle (Tribolium confusum). GC-MS analysis showed that 1,8-cineole was the major component of the essential oils. The vapours of laurel essential oil were toxic to all the stages of T. confusum (Isikber et al., 2006). Repellency and toxicity of essential oil from L. nobilis (Lauraceae) against the rust-red flour beetle T. castaneum Herbst) were also reported by Andronikashvili and Reichmuth (2003). The toxicity of ethanol extracts from L. nobilis on the large diamondback moth, Plutella xylos-tella, was 55% (Erturk et al., 2004).

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]. 

Table I shows the insecticidal activity of 1,2-benzenedicarboxamides. Insecticidal activities are shown as EC5Q values against common cutworm Spodoptera litura) and diamondback moth Plutella xylostdla).

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.
