TL;DR: It is demonstrated that flies experienced three episodes of rapid radiation—lower Diptera (220 Ma), lower Brachycera (180 Ma), and Schizophora (65 Ma)—and a number of life history transitions to hematophagy, phytophagy and parasitism in the history of fly evolution over 260 million y.
Abstract: Flies are one of four superradiations of insects (along with beetles, wasps, and moths) that account for the majority of animal life on Earth. Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms, yet recent research has suggested that fly relationships have been obscured by multiple episodes of rapid diversification. We provide a phylogenomic estimate of fly relationships based on molecules and morphology from 149 of 157 families, including 30 kb from 14 nuclear loci and complete mitochondrial genomes combined with 371 morphological characters. Multiple analyses show support for traditional groups (Brachycera, Cyclorrhapha, and Schizophora) and corroborate contentious findings, such as the anomalous Deuterophlebiidae as the sister group to all remaining Diptera. Our findings reveal that the closest relatives of the Drosophilidae are highly modified parasites (including the wingless Braulidae) of bees and other insects. Furthermore, we use micro-RNAs to resolve a node with implications for the evolution of embryonic development in Diptera. We demonstrate that flies experienced three episodes of rapid radiation—lower Diptera (220 Ma), lower Brachycera (180 Ma), and Schizophora (65 Ma)—and a number of life history transitions to hematophagy, phytophagy, and parasitism in the history of fly evolution over 260 million y.
TL;DR: One shore fly species, Psilopa clara (Wollaston, 1858), is recorded for the first time from Egypt, and two new synonyms of shore flies are proposed.
Abstract: We present a catalogue of all known taxa of the superfamily Ephydroidea in Egypt. Old World synonymies, type localities, type depositories, world distributions by biogeographic realm(s) and country, Egyptian localities and dates of collection are provided. A total number of 117 species belonging to 45 genera, 18 tribes, 7 subfamilies, and representing 3 families has been catalogued. The treated families are: Ephydridae (shore flies or brine flies), Drosophilidae (vinegar flies or fruit flies) and Braulidae (bee lice). One shore fly species, Psilopa clara (Wollaston, 1858), is recorded for the first time from Egypt. Two new synonyms of shore flies are proposed, namely: Philotelma ulianai Raffone, 2011 = Ephydra (Ephydra) macellaria Egger, 1862 and Notiphila rufitarsis Macquart, 1851 = Allotrichoma biroi Cresson, 1929. Lectotypes are designated for three shore fly species, namely: Psilopa pectinata Hendel, 1931; Rhynchopsilopa nitidissima Hendel, 1931 and Notiphila rufitarsis Macquart, 1851.
Abstract: . Megabraula gen.n. is erected for two new species, M.antecessor and M.onerosa, both found coinhabiting nests of Apis laboriosa in Nepal. Because of their many modifications, the features that distinguish Braula, the other genus in the family, and Braulidae in general are revised. Braulid biology is reviewed, particularly the adaptations involved with the origin of and progressive specialization to commensalism with honey bees.
TL;DR: This study showed the first record of the infestation of honeybee's hives by B. cœcain Benin, suggesting the probable presence of this parasite in most of the West African countries.
Abstract: One of the important parasites of honeybees is the bee louse, Braula cœca, which contribute to weaken or lead to the destruction of beehives worldwide. However, until recently, studies in Nigeria and in many other sub-Saharan African countries did not show the presence of parasite on bees in West Africa. The present study aimed at investigating the presence and importance of B. cœcain Benin. The studies were conducted in eighteen hives located in six different sites in the North-eastern part of Benin. In each site, three hundreds to five hundreds bees were examined. Honeybees were placed in 70% ethanol and shacked. Thereafter, honeybees were examined for the presence ofbee louse, in the liquid and at the bottom of the jar. Quick diagnoses using oxalic acid, formic acid and tobacco leaves were also undertaken. Results showed variation of the level of infestation from 0.25 ± 0.25 % on the bee hives at Dabou to 4.63 ± 2.22% on bee colony of the University campus of Parakou. This study showed the first record of the infestation of honeybee's hives by B. cœcain Benin, suggesting the probable presence of this parasite in most of the West African countries. Implementation of sustainable conservation measures to protect diversity of the bees in Benin is therefore needed.
