A preliminary catalogue of the moths (Lepidoptera except Papilionoidea) of Tobago, West Indies

This catalogue comprises records of 355 species of moths (non-papilionoid Lepidoptera) from Tobago, of which 15 are partially identified. Of this total, all except 17 (5%) are known from Trinidad, although not all these records from Trinidad are published yet. Of these 17, eleven are expected to occur in Trinidad as they also occur on the mainland of South America and two are only known from Tobago but will probably also occur in Trinidad. This leaves just four species (1% of the total) that are known from the Lesser Antilles and are currently not known from further south than Tobago. The families represented by the most species are Erebidae, Crambidae, Geometridae, Noctuidae and Sphingidae, which between them account for 73% of records. Taxonomic changes are made as follows. Podalia farmbri (Kaye, 1925) sp. rev. (Megalopygidae) is removed from the synonymy of P. nigrescens Schaus, 1905. Podalia walkeri Hopp, 1935 and P. dimidiata (Walker, 1865) are syn. nov. of P. farmbri Kaye, 1925. Renia bipunctata (Kaye, 1901) (Erebidae) is a comb. nov. for Zanclognatha bipunctata. Aristaria trinitalis Schaus, 1906 (Erebidae) is a syn. nov. of Renia bipunctata Kaye, 1901. Aglaonice deldonalis Walker, 1859 sp. rev. (Erebidae) is removed from the synonymy of A. hirtipalpis Walker, [1859]. Plusiodonta cupristria Kaye, 1923 (Erebidae) is a syn. nov. of Oraesia excitans Walker [1858]. Oroscopa abluta (Schaus, 1912) (Erebidae) is a comb. nov. for Freilla abluta Schaus, 1912, which is a new combination in common use, but not previously published. Ptichodis dorsalis (Fabricius, 1797) (Erebidae) is a comb. nov. for Noctua auct. dorsalis Fabricius, a new combination already in use, but not formally published. I endorse the unpublished conclusion of I.W.B. Nye that Ptichodis basilans (Guenée, 1852) is a syn. nov. of Ptichodis dorsalis (Fabricius, 1797). Ptichodis agrapta Hampson, 1913 is also a syn. nov. of Ptichodis dorsalis (Fabricius, 1797).

Evolutionary genomics of a cold-adapted diatom: Fragilariopsis cylindrus

The Southern Ocean houses a diverse and productive community of organisms1, 2. Unicellular eukaryotic diatoms are the main primary producers in this environment, where photosynthesis is limited by low concentrations of dissolved iron and large seasonal fluctuations in light, temperature and the extent of sea ice3, 4, 5, 6, 7. How diatoms have adapted to this extreme environment is largely unknown. Here we present insights into the genome evolution of a cold-adapted diatom from the Southern Ocean, Fragilariopsis cylindrus8, 9, based on a comparison with temperate diatoms. We find that approximately 24.7 per cent of the diploid F. cylindrus genome consists of genetic loci with alleles that are highly divergent (15.1 megabases of the total genome size of 61.1 megabases). These divergent alleles were differentially expressed across environmental conditions, including darkness, low iron, freezing, elevated temperature and increased CO2. Alleles with the largest ratio of non-synonymous to synonymous nucleotide substitutions also show the most pronounced condition-dependent expression, suggesting a correlation between diversifying selection and allelic differentiation. Divergent alleles may be involved in adaptation to environmental fluctuations in the Southern Ocean

Add-on cannabidiol treatment for drug-resistant seizures in tuberous sclerosis complex

Importance Efficacy of cannabidiol has been demonstrated in seizures associated with Lennox-Gastaut and Dravet syndromes but appears not yet to have been established in conditions with primarily focal seizures, such as tuberous sclerosis complex (TSC).Objective To evaluate efficacy and safety of 25-mg/kg/day and 50-mg/kg/day cannabidiol dosages vs placebo against seizures associated with TSC.Design, Setting, and Participants This double-blind, placebo-controlled randomized clinical trial (GWPCARE6) enrolled patients between April 6, 2016, and October 4, 2018; follow-up was completed on February 15, 2019. The trial was conducted at 46 sites in Australia, Poland, Spain, the Netherlands, United Kingdom, and United States. Eligible patients (aged 1-65 years) were those with a clinical diagnosis of TSC and medication-resistant epilepsy who had had at least 8 TSC-associated seizures during the 4-week baseline period, with at least 1 seizure occurring in at least 3 of the 4 weeks, and were currently taking at least 1 antiepileptic medication.Interventions Patients received oral cannabidiol at 25 mg/kg/day (CBD25) or 50 mg/kg/day (CBD50) or a matched placebo for 16 weeks.Main Outcomes and Measures The prespecified primary outcome was the change from baseline in number of TSC-associated seizures for cannabidiol vs placebo during the treatment period.Results Of 255 patients screened for eligibility, 31 were excluded and 224 were randomized. Of the 224 included patients (median [range] age, 11.4 [1.1-56.8] years; 93 female patients [41.5%]), 75 were randomized to CBD25, 73 to CBD50, and 76 to placebo, with 201 completing treatment. The percentage reduction from baseline in the type of seizures considered the primary end point was 48.6% (95% CI, 40.4%-55.8%) for the CBD25 group, 47.5% (95% CI, 39.0%-54.8%) for the CBD50 group, and 26.5% (95% CI, 14.9%-36.5%) for the placebo group; the percentage reduction from placebo was 30.1% (95% CI, 13.9%-43.3%; P < .001) for the CBD25 group and 28.5% (95% CI, 11.9%-42.0%; nominal P = .002) for the CBD50 group. The most common adverse events were diarrhea (placebo group, 19 [25%]; CBD25 group, 23 [31%]; CBD50 group, 41 [56%]) and somnolence (placebo group, 7 [9%]; CBD25 group, 10 [13%]; CBD50 group, 19 [26%]), which occurred more frequently with cannabidiol than placebo. Eight patients in CBD25 group, 10 in CBD50 group, and 2 in the placebo group discontinued treatment because of adverse events. Twenty-eight patients taking cannabidiol (18.9%) had elevated liver transaminase levels vs none taking placebo.Conclusions and Relevance Cannabidiol significantly reduced TSC-associated seizures compared with placebo. The 25-mg/kg/day dosage had a better safety profile than the 50-mg/kg/day dosage

Host Specificity of Epiplema albida: A Potential Biological Control Agent for Sri Lankan Privet in the Mascarene Islands

Epiplema albida (Hampson) (Lepidoptera: Uraniidae, Epipleminae) from Sri Lanka, was studied to assess its safety for use as a biological control agent for Sri Lankan privet, Ligustrum robustum subsp. walkeri (Oleaceae) in La Réunion and other Mascarene Islands. Larval no-choice feeding tests using newly hatched larvae, larval development tests, and multiple choice oviposition tests were used. Adult females of E. albida are shown to have highly selective oviposition behaviour and the species is physiologically restricted to very few hosts for feeding and development. The risk to key test plants in La Réunion is minimal, so this species can be considered for use as a biological control agent there, but would need further evaluation for potential use elsewhere
