Transgenic cry1C or cry2A rice has no adverse impacts on the life-table parameters and population dynamics of the brown planthopper, Nilaparvata lugens (Hemiptera: Delphacidae)

Abstract:
BACKGROUND
Transgenic rice producing the insecticidal protein from Bacillus thuringiensis Berliner (Bt) is protected from damage by lepidopteran insect pests. However, one of the main concerns about Bt rice is the potential impact on non-target herbivores. In the present study, the ecological impacts of two Bt rice lines, T1C-19 expressing Cry1C protein and T2A-1 expressing Cry2A protein, on the non-target herbivore brown planthopper (BPH), Nilaparvata lugens (Stål), were evaluated under laboratory and field conditions. The purpose was to verify whether these Bt rice lines could affect the performance of BPH at individual and population scales.
RESULTS
Laboratory results showed that most of the fitness parameters (development duration, survival rate, fecundity, fertility, amount of honeydew excreted) of BPH were not significantly affected by the two tested Bt rice lines, although the development duration of fourth-instar nymphs fed on T1C-19 was distinctly longer compared with that on T2A-1 and non-Bt rice plants. Five life-table parameters did not significantly differ among rice types. Two-year field trials also revealed no significant difference in population dynamics of BPH among rice types.
CONCLUSION
It is inferred that the tested Bt rice lines are unlikely to affect the population growth of BPH.
