Heterologous investigation of metabotropic and ionotropic odorant receptors in ab3A neurons of Drosophila melanogaster. [PDF]
, 2023 In insects, antennal ionotropic receptors (IRs) and odorant receptors (ORs) are among the main sensors of olfactory cues. To functionally characterize the subunits from these receptors, the use of ab3A neurons from transgenic Drosophila melanogaster ...

r DNA sequence analysis and morphological redescription of Empoasca onukii from the tea growing area of Fujian [PDF]
, 2015 重新描述了小贯小绿叶蝉的形态结构,尤其是头部色斑、翅脉、腹部内突、下生殖板及其刚毛着生位置,并增加了足部(刺毛列)特征描述。通过PCr技术克隆得到该物种的r dnA序列,包括部分18S(1 843bP)和28S序列(667 bP)以及完整的5.8S(155 bP)、ITS1(3 114 bP)和ITS2序列(1 008 bP)。序列分析表明,18S,5.8S,28S与其他物种间具有90%~95%的序列一致性;而ITS1和ITS2序列变异性非常大。碱基组成比率分析显示ITS1以及ITS2具有AT偏好性 ...

Changes in Tea Plant Secondary Metabolite Profiles as a Function of Leafhopper Density and Damage
Frontiers in Plant Science, 2020 Insect herbivores have dramatic effects on the chemical composition of plants. Many of these induced metabolites contribute to the quality (e.g., flavor, human health benefits) of specialty crops such as the tea plant (Camellia sinensis).

Ecology and Evolution, Volume 14, Issue 4, April 2024.In this study, the mitochondrial genomes of 10 erythroneurine species were sequenced, and sequences of four genes were obtained for 12 geographical populations of Seriana bacilla. The new sequence data were combined with previously available mitochondrial DNA sequence data and analyzed using Bayesian and Maximum‐Likelihood‐based phylogenetic methods to

Population structure and genetic differentiation of tea green leafhopper, Empoasca (Matsumurasca) onukii, in China based on microsatellite markers [PDF]
Scientific Reports, 2019 AbstractThe tea green leafhopper, Empoasca (Matsumurasca) onukii Matsuda, is one of the dominant pests in major tea production regions of East Asia. Recent morphological studies have revealed variation in the male genitalic structures within and among populations. However, the genetic structure of this pest remains poorly understood.

Molecular Ecology Resources, Volume 24, Issue 3, April 2024.Abstract Leafhoppers comprise over 20,000 plant‐sap feeding species, many of which are important agricultural pests. Most species rely on two ancestral bacterial symbionts, Sulcia and Nasuia, for essential nutrition lacking in their phloem and xylem plant sap diets. To understand how pest leafhopper genomes evolve and are shaped by microbial symbioses,
