The brown planthopper (BPH), Nilaparvata lugens, is the most important pest of rice world wide (Oercke, 1994). Natural resistance offers an inexpensive and environmentally benign form of pest…

Some plant species have utility in both conservation biological control and as source of botanical insecticides that are relatively benign to natural enemies, however, in this crop system the additional cost was not justified by greater levels of pest suppression than achieved from border plants alone.

Given the specificity of change to GTX I, and its differential toxicity to some bee species, it is concluded that its expression was likely to have been influenced during invasion by interaction with herbivores/consumers, either via pollinator-mediated selection or enemy release from floral antagonists.

Testing orientation towards a food odour in combination with a colour cue in three storage pest beetle species, using motion tracking to monitor their behaviour found no visual responses by the two grain borers, suggesting their different host-seeking behaviours and ecological background should be taken into account when devising control methods.
