LncRNAs are potentially involved in the immune interaction between small brown planthopper and rice stripe virus

Journal of Integrative Agriculture, 2019
Small brown planthopper (SBPH, Laodelphax striatellus Fallén) is an important vector of major crop pathogen rice stripe virus (RSV). Controlling SBPH population is an efficient approach to control RSV.

Differences in Induced Volatile Emissions among Rice Varieties Result in Differential Attraction and Parasitism of Nilaparvata lugens Eggs by the Parasitoid Anagrus nilaparvatae in the Field [PDF]

, 2018
We compared the volatiles of JA-treated plants of six rice varieties and then determined, in the laboratory and field, if they differed in attractiveness to Anagrus nilaparavate Pand et Wang, an egg parasitoid of rice planthoppers.

Laboratory and Field Assessments of Prey-Mediated Effects of Transgenic Bt Rice on Ummeliata insecticeps (Araneida: Linyphiidae) [PDF]

, 2017
One major concern regarding the release of Bt rice is its potential impact through tritrophic interactions on nontarget arthropods, especially natural enemies. We studied the effects of two Bt transgenic rice varieties, TT9- 3 and KMD1, expressing Cry1Ab/
