“…Further survey work in three consecutive summers from 2011 to 2013 recovered about 100∼200 larvas from six counties in Qinling Mountains per year and observed less than three mature individuals during the eclosion seasons per day (Guo, 2013). Such a small population size and low eclosion rate suggest this species faces a high threat of extinction and should be re-evaluated as "Endangered" (Dong et al, 2014;Guo et al, 2014;Fang et al, 2019). L. taibai is also classified as a species of "Beneficial or Have Important Economic and Scientific Research Value" by the National Forestry and Grassland Administration.…”

Conservation genomic resources over the past decade has drastically improved, since genomes can be used to predict diverse parameters vital to conservation management. Luehdorfia taibai is an endemic butterfly only found in restricted aeras in middle-west China and is critically endangered. It was classfied as a vunerlable (VN) species in the “China species red list.” Here we generated 34.38 Gb of raw DNA sequencing reads and obtained a high-qualified draft genome assembly of L. taibai. The final genome is ~683.3 Mb, with contig N50 size of 10.19 Mb. Further, 98.6% of single-copy orthologous genes have been recovered by BUSCO. An estimated 42.34% of the genome of L. taibai consists of repetitive elements. Combined with gene prediction and transcriptome sequencing, genome annotation produced 15,968 protein-coding genes. Additionally, a nearly 1:1 orthology ratio of syntenic blocks between L. taibai and its closest genome Luehdorfia chinensis suggested that the genome structures have not changed much after speciation. The genome of L. taibai have not undergone a whole genome duplication event. Population dynamics analyses indicates that L. taibai has an extremely low heterozygosity of 0.057%, and its population size has declined dramatically over the past 10 thousand years. Our study describes a draft genome assembly of the L. taibai, the first implication of this species. We consider the globally overexploited of the host plants is not the main reason to threaten L. taibai. The genome will provide advice for the conservation to the economically important Luehdorfia lineage and this specific species.

“…However, the impact of smoke on insect flight behaviour has rarely been considered, despite flight performance largely determining dispersal capacity, which then profoundly influences metapopulation dynamics and ultimately population viability, species persistence, gene flow, and processes of natural selection (Bowler & Benton, 2005;Lester et al, 2007;Berg et al, 2010;Danthanarayana, 1986). Certain of the seasonal biomass burning patterns in Asia (Vadrevu et al, 1986) coincide with the period in which many insects start to migrate (Huang et al, 2012;Jones et al, 2016;Fang et al, 2019), and this is likely to be the case in other continents as well. Increasing our understanding of insect flight performance in smoke-contaminated air may ultimately help elucidate whether the air pollution associated with these fires might affect insect migration, and all the consequent impacts that stem from any such effect.…”

1. A major component of biomass burning smoke is fine particulate matter (PM 2.5), which has been shown to generate impacts on insect population dynamics and development. However, little is known about its effect on insect flight behaviour, even though this will influence insect dispersal and distribution, and potentially migration and ecosystem services such as pollination. 2. Here we use a tethered flight mill setup to examine the behaviour of adult painted lady butterflies (Vanessa cardui L.) flying in different levels of combustion-generated airborne PM 2.5 , comparison this to TFM flying under 'clean air' conditions. 3. Descriptive statistics and paired sample t-tests indicate that the smoke had a significantly deleterious impact on flight behaviour, with for example total flight distance covered declining by 65% during the first 20 min of flying in the least smoke contaminated air compared to 'clean air' control conditions, whilst average speed declined by 54% and flight duration by 32%. A strongly negative and highly significant linear correlation between flight speed and PM 2.5 concentration was also observed. 4. This study represents the first time that smoke effects on insect flight behaviour have been experimentally tested, and the longer the butterflies were exposed to the elevated PM 2.5 concentrations the more obviously their flight behaviour declined. We conclude that the month(s)-long episodes of air pollution often associated with agricultural burning and deforestation fires in the tropics may well be significantly affecting the behaviour of the flying insects living in those regions and/or who migrate through them.
