Influence of the RDL A301S mutation in the brown planthopper Nilaparvata lugens on the activity of phenylpyrazole insecticides [PDF]
We discovered the A301S mutation in the RDL GABA-gated chloride channel of fiprole resistant rice brown planthopper, Nilaparvata lugens populations by DNA sequencing and SNP calling via RNASeq. Ethiprole selection of two field N.

MdRLKT1–MdRAX2–MdMKS1 Module Positively Regulating Resistance to Cytospora mali in Apple
ABSTRACT Valsa canker (caused by Cytospora mali = Valsa mali. C. mali) is one of the most destructive diseases affecting apple cultivation. The scarcity of natural germplasm resources with high resistance and immunity underscores the importance of exploring plant immune regulation factors of disease‐resistant breeding.

Genetics of field resistance of rice to brown planthopper
The brown planthopper [Nilaparvata lugens (Stal)] is one of the most serious insect pests of rice (Oryza sativa L.) in South and Southeast Asia. Because cultivars with vertical resistance to brown planthopper have "broken down" due to brown planthopper ...

Rice Black-streaked Dwarf Virus Preparation and Infection on Rice
Rice black-streaked dwarf virus (RBSDV), a member of genus Fijivirus in the family Reoviridae, infects rice, maize, barley and wheat, and can seriously affect crop yields. RBSDV is transmitted by the small brown planthopper (Laodelphax striatellus, SBPH)

Studies on Feeding Habits of the Brown Planthopper
1) トビイロウンカの吸汁活動におよぼす各種アミノ酸,糖,および核酸有機塩基化合物の効果を調べた。2) 各種供試化合物の効果は吸汁指数,すなわち各種化合物の水溶液をパラフィルムをとおしてウンカに吸汁させた場合の口針挿入1回当り排出される甘露小滴数の平均値を統計処理し比較検討した。3) 供試した19種類のアミノ酸のうち,L-アスパラギン酸とL-グルタミン酸が最も強い吸汁促進効果を有することが判明した。ついでD-アスパラギン酸,L-アラニン,L-アスパラギン,およびL-バリンがかなり強い吸汁効果を示した。一般にこれらのアミノ酸溶液を吸汁させた場合,口針挿入頻度が低下し,甘露排出量が増加する傾向があった。4) 庶糖を含む7種類の糖類の吸汁促進作用はいずれも弱かった。しかし庶糖と吸汁促進効果を有するL ...
