Myzus green peach aphid

Cuticular diterpenes-duvanes and labdanes. Cutler have found that the cuticular diterpenes of green tobacco have both allelopathic and insect-deterrent effects (38). Present in the cuticle are duvane and/or labdane diterpenes (Figure 3) The levels of these specific cuticular components are believed to be responsible for the observed resistance of some types of tobacco to green peach aphids Myzus persicae (Sulzer), tobacco budworm Heliothis virescens (F.), and tobacco hornworm Manduca sexta (L.) (39). 

Adult grass grubs (Costelytra zealandica)[209] and phloem feeding green peach aphids (Myzus persicae)[210] were observed to die after feeding on Ricinus communis 76 was identified as the responsible toxin. The presence of 76 in the phloem of R. communis indicated a possible role for the toxin in defense of the plant against aphids [210].

The most studied aspect of phytoalexin elicitation is that generated by fungal pathogens of plants. Karban et al.[22] found induced resistance and interspecific competition between spider mites and a vascular wilt fungus. McIntyre et al. [2A] demonstrated that 7 days after tobacco plants were infected with tobacco mosaic virus, reproduction of the green peach aphid, Myzus persicae, was significantly reduced on these infected plants. Inoculation of plants with tobacco mosaic virus induced resistance to several pathogens, however the mechanism for induced resistance was not characterized.

First, though, some explanations. The results reported in this section come from a simple primary screen with a top rate of 600 ppm (equivalent to 600 g/ha). The numbers shown are LC50 values in ppm. Wiile we tested against a broad spectrum of insects, we show here only the green peach aphid (GPA myzus persicae) and the mexican bean beetle (MBB Epilachna variuestis).
