  • Effects of Removal Or Reduced Density of the Malaria Mosquito, Anopheles
    Medical and Veterinary Entomology (2018), doi: 10.1111/mve.12327 REVIEW ARTICLE Effects of the removal or reduction in density of the malaria mosquito, Anopheles gambiae s.l., on interacting predators and competitors in local ecosystems C. M. COLLINS1 , J. A. S. BONDS2, M. M. QUINLAN1 and J. D. MUMFORD1 1Centre for Environmental Policy, Imperial College London, London, U.K. and 2Bonds Consulting Group LLC, Panama City Beach, Florida, U.S.A. Abstract. New genetic control methods for mosquitoes may reduce vector species without direct effects on other species or the physical environment common with insecticides or drainage. Effects on predators and competitors could, however, be a concern as Anopheles gambiae s.l. is preyed upon in all life stages. We overview the literature and assess the strength of the ecological interactions identified. Most predators identified consume many other insect species and there is no evidence that anyspecies preys exclusively on any anopheline mosquito. There is one predatory species with a specialisation on blood-fed mosquitoes including An. gambiae s.l.. Evarcha culicivora is a jumping spider, known as the vampire spider, found around Lake Victoria. There is no evidence that these salticids require Anopheles mosquitoes and will readily consume blood-fed Culex. Interspecific competition studies focus on other mosquitoes of larval habitats. Many of these take place in artificial cosms and give contrasting results to semi-field studies. This may limit their extrapolation regarding the potential impact of reduced An. gambiae numbers. Previous mosquito control interventions are informative and identify competitive release and niche opportunism; so while the identity and relative abundance of the species present may change, the biomass available to predators may not.

    Sánchez-Herrera et al. BMC Evolutionary Biology (2020) 20:74 https://doi.org/10.1186/s12862-020-01638-z RESEARCH ARTICLE Open Access An exploration of the complex biogeographical history of the Neotropical banner-wing damselflies (Odonata: Polythoridae) Melissa Sánchez-Herrera1,2* , Christopher D. Beatty3, Renato Nunes2,4, Camilo Salazar1 and Jessica L. Ware2,5 Abstract Background: The New World Tropics has experienced a dynamic landscape across evolutionary history and harbors a high diversity of flora and fauna. While there are some studies addressing diversification in Neotropical vertebrates and plants, there is still a lack of knowledge in arthropods. Here we examine temporal and spatial diversification patterns in the damselfly family Polythoridae, which comprises seven genera with a total of 58 species distributed across much of Central and South America. Results: Our time-calibrated phylogeny for 48 species suggests that this family radiated during the late Eocene (~ 33 Ma), diversifying during the Miocene. As with other neotropical groups, the Most Recent Common Ancestor (MRCA) of most of the Polythoridae genera has a primary origin in the Northern Andes though the MRCA of at least one genus may have appeared in the Amazon Basin. Our molecular clock suggests correlations with some major geographical events, and our biogeographical modeling (with BioGeoBEARS and RASP) found a significant influence of the formation of the Pebas and Acre systems on the early diversification of these damselflies, though evidence for the influence of the rise of the different Andean ranges was mixed. Diversification rates have been uniform in all genera except one—Polythore—where a significant increase in the late Pliocene (~ 3 mya) may have been influenced by recent Andean uplift.

In spite of this, there does not exist a survey of its fauna — except a single contribution, by Lord Walsingham, in Moore's "Lepidoptera of Ceylon", already almost a hundred years old, and a number of small papers and stray descriptions of new species, in various journals. The authors of these papers were Walker, Zeller, Lord Walsingham and a few other classics — until, starting with 1905, a flood of new descriptions 4 ZOOLOGISCHE VERHANDELINGEN I93 (1982) and records from India and Ceylon appeared, all by the hand of Edward Meyrick. He was almost the single specialist of these faunas, until his death in 1938. To this great Lepidopterist we chiefly owe our knowledge of all groups of Microlepidoptera of Sri Lanka. After his death this information stopped abruptly. In the later years great changes have taken place in the tropical countries. We are now facing, alas, the disastrously quick destruction of natural bio- topes, especially by the reckless liquidation of the tropical forests.
