[Effect of false flax (Camelina sativa) on larval feeding and adult behavioral response of the diamondback moth (Plutella xylostella)]
Acta Entomologica Sinica 47 (4), 474-478
Abstract: False flax, Camelina sativa (L.), an oil-bearing crop, has an outstanding resistance to phytophagous insects. Effect of false flax on larval feeding and adult behavioral response of the diamondback moth, Plutella xylostella (L.), one of the most damaging pests in cruciferous crops, were examined with bioassay and Y-olfactometer in the laboratory. With feeding on cabbage as the control, 1st instar larvae, fed on leaves of false flax, experienced a corrected death rate of 79.2% after 3 days, which indicated that false flax had an obvious antibiosis effect on the 1st instar larvae. 3rd instar larvae, fed on false flax, showed significantly lower survival rate, percentage pupation, pupa weight and shorter adult longevity compared with those fed on cabbage. The diamondback moth larvae preferred leaves of cabbage to false flax in feeding choice test. In no-choice test, the amount of false flax leaves consumed by the diamondback moth larvae was significantly lower than that of cabbage. However, the test showed that adults of the diamondback moth had the same orientation response to false flax and cabbage; compared to clean air, adults of the diamondback moth preferred odors from the plants of false flax or cabbage. These results indicated that the diamondback moth adults had an obvious orientation response to the volatiles of false flax.
