Diamondback moth is the only species that has evolved resistance to Bacillus thuringiensis in open field populations. Resistance has appeared several times and involves more than one mechanism, yet one type of resistance designated “Mode 1” occurs often in diamondback moth and other lepidopteran species. This type of resistance is very potent, shows recessive inheritance, displays a characteris...

Except for the chlorinated insecticides, all traditional insecticides and newly introduced IGR-type compounds have been investigated for their modes of action in respect to the resistance in diamondback moth, Plutella xylostella (L.) in Taiwan. Diamondback moth has a very active, efficient, and inducible mixed function oxidases (MFO) system/ complex, which is responsible for the high level of r...

Some extracts from neem seeds/neem seed kernels can give satisfactory to good control of diamondback moth, Plutella xylostella (L.), in cabbage and other crucifers. Water extracts prove most effective, sometimes even at low concentrations as low as 12.5 g of seed kernels per liter of water, provided the raw material contains sufficient azadirachtin. Neem could be developed into products suitabl...

Abstract Pheromones have become an environmentally friendly alternative to conventional insecticides for pest control. Most current pheromone-based control products target lepidopteran pests of high-value crops, as today’s manufacturing processes cannot yet produce pheromones at low enough costs enable their use lower-value especially commodity crops. Camelina sativa seeds genetically modified ...
