Thereafter, Minos Martelli and Luciano Süss hold the direction of the Journal until December 2011. In January 2012 the Editor decided for the new open-access on-line version of JEAR.</p> <p>The Journal publishes original research papers concerning Arthopods, but reviews, editorials, technical reports, brief notes, conference proceeding, letters to the Editor, book reviews are also welcome.</p> <p>JEAR has four main areas of interest:</p> <ul> <li><strong>Entomology</strong> (systematics; morphology; biology; biotechnology; agriculture, ornamental and forest entomology; applied entomology; integrated pest management; biological control; apiculture and apidology; medical, urban and veterinary entomology; etc.)</li> <li><strong>Stored product pests</strong> (biology; integrated pest management; etc.)</li> <li><strong>Insect Ecology</strong> (behaviour; biodiversity; taxonomy; plant insect interaction and ecosystems; biological control; alien species; etc.)</li> <li><strong>Acarology</strong> (systematics; morphology; biology; parasitology; control; etc.)</li> </ul> <p>The publication of manuscripts is subject to the approval of the Section Editor who has knowledge of the field discussed in the manuscript in accordance with the principles of Peer Review; referees will be selected from the Editorial Board or among qualified scientists of the international scientific community. Articles must be written in English and must adhere to the guidelines and details contained in the Instructions to Authors.</p> https://pagepressjournals.org/index.php/jear/article/view/8046 Feeding in the adult of Hermetia illucens (Diptera Stratiomyidae): reality or fiction? 2019-03-20T17:23:46+01:00 Costanza Jucker cojucker@gmail.com Daniela Lupi danylu72.dl@gmail.com Sara Savoldelli sara.savoldelli@unimi.it Maria Giovanna Leonardi mgiovanna.leonardi@unimi.it <p><em>Hermetia illucens</em> (L.) (Diptera Stratiomyidae) is a promising species as alternative protein source for animal feed, able to convert a wide range of organic materials. The knowledge on larval biology, development, nutritional needs, and nutritional composition is reach, while few information is available on adult traits. The aim of the present study was to investigate the influence of the adult nutrition on the survival, the longevity and the ovaries development of H. illucens. In detail, three food sources have been compared to starvation. Water, a sucrose solution and a protein solution were given to new emerged adults and data on longevity and ovary development were acquired. Trials were conducted on single specimen and on a cohort of adults. In all the trials, starved adults survived significantly shorter than all other thesis. When adults were maintained isolated, the survival was significantly influenced by the nourishment: longevity was longer when adults were feed with a sucrose solution, while the supply of a protein source provided a lifespan significantly higher than starvation but similar to water or to sucrose solution. In cages longevity was always shorter than in isolated adults for both males and females and the overall trend was similar to single individual trials with the exception of protein solution. Ovary development of females under different nourishment did not show differences. More studies are necessary to identify a correct nutrition considering (the integration of) different chemical compounds to obtain optimal adult performance in terms of longevity and reproduction.</p> 2019-03-20T16:06:29+01:00 ##submission.copyrightStatement## https://pagepressjournals.org/index.php/jear/article/view/7861 Can exotic drosophilids share the same niche of the invasive Drosophila suzukii? 2019-03-20T17:23:46+01:00 Nasim Amiresmaeili n.amiresmaili@gmail.com Costanza Jucker costanza.jucker@unimi.it Sara Savoldelli sara.savoldelli@unimi.it Daniela Lupi daniela.lupi@unimi.it <p>The presence of the four exotic drosophilids <em>Chymomyza amoena</em> (Loew), <em>Drosophila suzukii </em>(Matsumura)<em>, Zaprionus indianus </em>(Gupta) and <em>Zaprionus tuberculatus </em>Malloch has been investigated in different orchard in Northern Italy for two consecutive years. The presence and the abundance of the population of the drosophilid flies were surveyed with apple cider vinegar (ACV) traps, fruit baited traps and fruit collection. <em>C amoena</em>, <em>Z. tuberculatus</em> and <em>D. suzukii</em> have been identified in the ACV traps in both years. Only <em>D. suzukii</em> and <em>Z. tuberculatus</em> emerged from fruit baited traps. With the exception of <em>D. suzukii,</em> no other exotic drosofilid was captured flickered??? from the fruit collection. <em>Z. indianus</em> was never observed. Analysis of the presence of the different species, seasonal occurrence and sex ratio are provided.</p> 2019-03-20T15:52:06+01:00 ##submission.copyrightStatement## https://pagepressjournals.org/index.php/jear/article/view/7775 High mosquito diversity in an Amazonian village of Ecuador, surrounded by a Biological Reserve, using a rapid assessment method 2019-02-26T17:22:25+01:00 Paul-Leonardo Duque polduquebiologo@gmail.com Jonathan Liria jonathan.liria@gmail.com Sandra Enríquez sandrabycid@gmail.com Elena Burgaleta elena.burgaleta@uisek.edu.ec José Salazar jose.salazar@uisek.edu.ec Jazzmin Arrivillaga-Henríquez jazzmin.arrivillaga@gmail.com Juan-Carlos Navarro juancarlos.navarro@uisek.edu.ec <p>This research represents a study in an Amazonian village that has similar structures to others Kichwa Amazonian villages of Ecuador. We evaluated the diversity, ecology, possibility of mosquitoes/pathogens translocation from forest to urban area, and the vulnerability by potential mosquito vectors of diseases through an intensive and fast method done January 2017. Our analyses registered a high diversity of mosquitos in Limoncocha village (33 spp, H’ 2.76), which includes four new records of species for Ecuador. We propose the biological reserve and the lagoon are determinant environmental factors for the high mosquito diversity, plus the socioeconomic characteristics related with a deficient water pipeline supply and lack of solid waste system. Furthermore, the high diversity of sylvan mosquitoes registered throughout the area, that include several potential vectors, suggest a moderate to high vulnerability for the transference of pathogens from the Biological Reserve to the urbanized area, which may increase the circulation of little-known arboviruses (Mayaro, Ilheus, St Louis encephalitis) across Ecuador.</p> 2019-02-26T11:21:32+01:00 ##submission.copyrightStatement## https://pagepressjournals.org/index.php/jear/article/view/7836 A review of sulfoxaflor, a derivative of biological acting substances as a class of insecticides with a broad range of action against many insect pests 2019-01-10T09:46:22+01:00 L. Bacci bacci@dow.com S. Convertini bacci@dow.com B. Rossaro bruno.rossaro@unimi.it <p>Sulfoxaflor is an insecticide used against sap-feeding insects (Aphididae, Aleyrodidae) belonging to the family of sulfoximine; sulfoximine is a chiral nitrogen-containing sulphur (VI) molecule; it is a sub-group of insecticides that act as nicotinic acetylcholine receptor (nAChR) competitive modulators. Sulfoxaflor binds to nAChR in place of acetylcholine and acts as an allosteric activator of nAChR. Thanks to its mode of action resistance phenomena are uncommon, even few cases of resistance were reported. It binds to receptors determining uncontrolled nerve impulses followed by muscle tremors to which paralysis and death follows. Sulfoxaflor acts on the same receptors of neonicotinoids as nicotine and butenolides, but it binds differently. It binds to insects nAChRs more strongly than to mammals’ ones, so it is much less toxic for mammals and man. Sulfoxaflor is supposed to have a low environmental impact and is not much aggressive against non-target species. Unfortunately, it is toxic to impollinator insects, so it must be used only in compliance with a series of legislative norms. At present sulfoxaflor can be considered one of the most interesting products to be used in fighting against agriculture insect pests.</p> 2018-12-13T00:00:00+01:00 ##submission.copyrightStatement##
