Selenium-Tolerant Diamondback Moth Disarms Hyperaccumulator Plant Defense
BACKGROUND Some plants hyperaccumulate the toxic element selenium (Se) to extreme levels, up to 1% of dry weight. The function of this intriguing phenomenon is obscure. RESULTS Here, we show that the Se in the hyperaccumulator prince's plume (Stanleya pinnata) protects it from caterpillar herbivory because of deterrence and toxicity. In its natural habitat, however, a newly discovered variety...
متن کاملRearing of Diamondback Moth
Mass rearing methods on artificial diets and cruciferous seedlings for the diamondback moth, Plutella xylostella L, are reviewed and described briefly.
متن کاملEsterase Isozyme of Diamondback Moth
Electrophoresis is currently the best technique for quantifying inherited variation which has contributed to our knowledge of population biology in revealing population structure. Considerable variation in isozymes of diamondback moth, Plutella xylostella (L.), was detected. Esterase zymograms were prepared from 3rd and 4th instar larvae, pupae and adults. There were two groups of esterase band...
متن کاملInsecticide Resistance in Diamondback Moth
High levels of resistance to the major categories of insecticides, ie, organophosphorus, carbamates, pyrethroids, and DDT, have been detected in the diamondback moth in Taiwan. Synergist studies have provided insufficient evidence to show significant involvement of known metabolic systems, such as microsomal oxidation, esterase hydrolysis, and glutathione conjugation in organophosphorus and car...
متن کاملThe Migration of Diamondback Moth
The adults of diamondback moth, Plutella xylostella L, are known to have been transoceanic migrants in Europe since ancient times. The insect, which has its origin in Asia Minor, spread to other parts of the world with the spread of the cultivation of its host, the crucifers, and by using its own migrational abilities over long distances. Several large scale transoceanic migrations have been re...
