“…With regard to the GRLH rice plant preferences, one study reported that T2A rice did not influence host preference of a target pest, the leaffolder, Cnaphalocrocis medinalis Guenée (Lepidoptera: Pyralidae) [ 33 ]. Similarly, the T1C-19 rice did not alter the host preferences of the non-target stored product pest, Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae), its parasitoid wasp, Anisopteromalus calandrae (Howard) (Hymenoptera, Pteromalidae) [ 34 ], or the host-searching behavior of another parasitoid, Cotesia chilonis (Matsumura) (Hymenoptera: Braconidae) [ 35 ]. These findings make sense as T2A-1 and T1C-19 rice had volatile profiles similar to their non-Bt controls [ 33 – 35 ].…”

The advent of genetically modified (GM) Bt rice creates the possibility of interactions among Bt crops, crop pathogens and non-target herbivores. In particular, information on how pathogen-infected Bt-expressing plants will influence non-target herbivores is necessary to predict the sustainability of GM cropping systems. Laboratory bioassays were conducted to evaluate the potential combined impacts of rice dwarf virus (RDV) and two Bt rice lines, T1C-19 (Cry1C) and T2A-1 (Cry2A), on non-target green rice leafhopper (GRLH), Nephotettix cincticeps (Uhler) (Hemiptera: Cicadellidae). In the first experiment, GRLHs feeding preference tests on Bt rice lines compared to a parental control rice line, MH63, were conducted. As rice plants were uninfected with RDV, GRLHs generally preferred the control MH63 line over the two Bt lines during the initial 8 h, with no significant preference during the following 64 h. As rice plants were infected with RDV, there were no clear preferences between the Bt rice lines and the control MH63 line. In the second experiment, we assessed the combined influence of RDV-infection status and Bt rice lines on GRLH biological parameters. Egg duration, adult weights, and male adult longevity were significantly affected on RDV-infected Bt rice. Other parameters, egg hatching rate, nymph survival and fecundity were not significantly influenced. We infer that interaction effect among two testing Bt rice lines and RDV will not lead to enlarged pest populations, thus demonstrating that growing these two Bt rice lines will poses negligible risk to GRLH in sustainable rice agroecosystems. Long-term field experiments to monitor the population dynamics of GRLHs at large scale need to be carried out to confirm the current results.

As pests are an important factor in reducing crop yields, pest control is an important measure in preventing reductions in crop yields. With the aim of ending the use of chemical pesticides, biological control and genetically modified methods are now considered more reasonable pest control strategies. The bacterium Bacillus thuringiensis (Bt) can produce crystal proteins that have specific toxicity to lepidopteran insects, and so it has been applied as a microbial insecticide in the control of crop pests for several decades. With the development of plant genetic engineering, Bt genes encoding insecticidal crystal protein have been introduced into many crop species for pest control. This article indicates that, after years of experiments and research, Bt transgenic rice is close to becoming a commercial insect-resistant rice, and many studies have shown that transgenic rice has pronounced abilities in the control of pests such as yellow stem borers (Scirpophaga incertulas, YSB), striped stem borers (Chilo suppressalis, SSB), and rice leaf rollers (Cnaphalocrocis medinalis, RLR); moreover, it does not obviously differ from non-transgenic rice in terms of safety. This paper suggests that transgenic Bt rice has application potential and commercial value.

“…Consistently, BPH showed no feeding preference between undamaged Huahui 1 (Cry1Ab/Cry1Ac rice) and its non-Bt parental rice MH63 in both laboratory and field-cage experiments 15 . And rough rice grains of T1C-19 did not change the host preference of the non-target stored-product pest, Rhyzopertha dominica (Coleoptera: Bostrichidae) and its parasitoid wasp Anisopteromalus calandrae (Hymenoptera: Pteromalidae) 34 . The effects of rice type, RDV infection status and their interaction on biological parameters of BPH were also investigated.…”

The potential risks of Bt rice on non-target arthropods (NTAs) should be evaluated and defined before commercial production. Recently, effects of Bt rice on NTAs under abiotic and biotic stress conditions attracted much attention. Here we reported the effects of Bt rice T1C-19 (Cry1C rice) on the non-target herbivore, Nilaparvata lugens (rice brown planthopper, BPH) with or without RDV (rice dwarf virus) infection conditions. BPH showed no feeding and oviposition preference between Bt rice T1C-19 and its non-Bt parental rice Minghui 63 (MH63), as well as between RDV-infected and RDV-free rice plants. Meanwhile, rice type, RDV infection status, and their interaction had little impacts on the survival, development and fecundity of BPH. By comparison with non-Bt control, Bt rice T1C-19 with or without RDV infection had no significant effects on the life-table parameters of BPH including rm, R0, T, DT and λ. Thus, it could be concluded that Bt rice T1C-19 doesn’t affect the ecological fitness of BPH either under RDV stress or not.
