Elimination of Dengue by Control of Aedes Vector Mosquitoes (Diptera: Culicidae) Utilizing Copepods (Copepoda: Cyclopidae)
International Journal of Bioinformatics and Biomedical Engineering Vol. 1, No. 2, 2015, pp. 101-106 http://www.aiscience.org/journal/ijbbe Elimination of Dengue by Control of Aedes Vector Mosquitoes (Diptera: Culicidae) Utilizing Copepods (Copepoda: Cyclopidae) Muhammad Sarwar * Nuclear Institute for Agriculture & Biology, Faisalabad, Punjab, Pakistan Abstract This paper reports on the information and result of long-term laboratory and field studies on copepods (Copepoda: Cyclopidae) as predators for mosquito control inhabiting in tropic and subtropic environments. Mosquitoes have long been vectors of numerous diseases that affect human health and well-being in many parts of the world. Reducing the use of pesticides against insect vectors is one of the big demands of the society because public has always been against the heavy use of insecticides. Copepods are natural and tiny shrimp-like crustacean with a hearty appetite for feeding on mosquito larvae in water holding areas. The copepods thrive in fresh and marine water, and are valuable tool in battling mosquitoes in artificial containers, roadside ditches, small water pools, clogged downspouts and other wet areas that can breed plenty of mosquitoes. These are especially helpful tools in fighting mosquitoes near public places, where use of certain pesticides is restricted. Copepods are relatively easy to culture, maintain and deliver to the target areas, but getting the cultures started requires some effort and time. Copepods are more efficient predator of younger than of older larvae of mosquito and predation drops considerably for 4 days and older larvae. Copepods though prefer to prey on younger larvae, yet also increasingly attack on older larvae as greater predator densities reduce the supply of younger ones. -
The Sarcoplasmic Reticulum of Striated Muscle of A
THE SARCOPLASMIC RETICULUM OF STRIATED MUSCLE OF A CYCLOPOID COPEPOD WOLF H. FAHRENBACH, Ph.D. From the Department of Anatomy, Harvard Medical School, Boston ABSTRACT The fine structure of the abdominal musculature of the copepod Macrocyclops albidus was investigated by electron microscopy. Tubules penetrate into the muscle fibers from the sarcolemma, continuity between the wall of the tubules and the sarcolemma being clear. A dense network of tubules envelops the myofibrils, its interstices being occupied by cisternal elements. At the Z lines the tubules traverse the interior of myofibrils, giving off branches which course longitudinally within the substance of the myofibrils. These branches are also accompanied by elongate, non-intercommunicating cisternae. Comparison of this fast acting copepod muscle with other vertebrate and invertebrate muscles indicates that the complexity of the tubular system is a function of the myofibrillar geometry, whereas the degree of development of the cisternal system is related to the contraction speed of the muscle.

The study of small water bodies contributes to understanding aquatic organisms’ adaptation to sharp fluctuations in external factors. Studies of biological com- munities’ response to fluctuations in external factors can be used for bioindication of the ecological state of small water bodies. In this regard, the purpose of the research is to study the structure of zooplankton of small lakes in South-East Kazakhstan in connection with various physicochemical parameters to understand the role of biological variables in assessing the ecological state of aquatic Citation: Aubakirova, M.; Krupa, E.; ecosystems.

DISEASES OF AQUATIC ORGANISMS Published June 18 Dis, aquat. Org. Horizontal transmission and subsequent development of Amblyospora californica (Microsporida: Amblyosporidae) in the intermediate and definitive hosts James J. Becnel US Department of Agriculture, Agricultural Research Service, Medical and Veterinary Entomology Research Laboratory, PO Box 14565, Gainesville, Florida 32604, USA ABSTRACT: Amblyospora californica (type species) was transmitted horizontally by feeding meiospores from larvae of Culex tarsalis (definitive host) to the copepod Macrocyclops albidus (a new intermediate host) and, conversely, by feeding spores produced in adult copepods to larval mosquitoes. Key features of the developmental sequence resulting from the 2 transmissions were demonstrated with both light and electron microscopy. Development in the copepod started with uninucleate sporoplasms from the ingested meiospores, included merogony by binary division of uninucleate meronts, sporogony by binary (usually) or multiple division and production of uninucleate-lanceolate spores within individual envelopes. Development in the mosquito began with uninucleate sporoplasms from the ingested lanceolate spores, included a first merogony (gametogony), plasmogamy, nuclear assoclation, a second merogony and dlsporous sporulation with the production of Nosema-llke spores in the adult female. This female represents a parental generat~onthat transmits the Infection transovanally (vertically) to male and female progeny. By combining results of this study with published data on development in filial generation mosquitoes, it was possible to outline the complete life cycle.

The utility of various regions of the ribosomal repeat unit for phylogenetic analysis was examined in 16 species representing four families, nine genera, and two orders of the subclass Copepoda (Crustacea). Fragments approximately 2000 bp in length containing the ribosomal DNA (rDNA) 18S and 28S gene fragments, the 5.8S gene, and the internal transcribed spacer regions I and II (ITS1 and ITS2) were amplified and analyzed. The DAMBE (Data Analysis in Molecular Biology and Evolution) software was usedto analyze the saturation of nucleotide substitutions; this test revealed the suitability of both the 28S gene fragment and the ITS1/ITS2 rDNA regions for the reconstruction of phylogenetic trees. -

Ultrastructure and Molecular Phylogeny of Mrazekia Macrocyclopis Sp

PAVLOVA1, Vyacheslav V. DOLGIKH1 1All-Russian Institute of Plant Protection, Russian Academy of Agricultural Sciences, St. Petersburg-Pushkin, Russia; 2State Research Institute of Lake and River Fisheries, St. Petersburg, Russia; 3I.M. Sechenov Institute of Evolutionary Physiology and Biochemistry, Russian Academy of Sciences, St. Petersburg, Russia Summary. The ultrastructure and molecular phylogeny of a new microsporidium Mrazekia macrocyclopis sp.n., a parasite of the copepod Macrocyclops albidus (Jur.) in North-West of Russia are described. All stages of its life cycle are diplokaryotic. Fresh spores are rod-shaped and 7.3–10.5 × 1.6–2.3 µm in size. Spore ultrastructure is typical of Mrazekia. The polar tube consists of the anterior clavate manubrium followed by a thin filament arranged in 3.5–4.5 nearly vertical coils. Spores are enclosed in individual sporophorous vesicles. SSU rDNA sequence analysis showed attribution of the new species to a cluster of microsporidia infecting insects (Cystosporogenes, Endoreticulatus), microsrustaceans (Glugoides), vertebrates (Vittaforma) and ciliates (Euplotespora) nested within the clade IV sensu Vossbrinck, Debrun- ner-Vossbrinck (2005). Mrazekia macrocyclopis is not therefore closely related to Bacillidium vesiculoformis, another microsporidium with rod-shaped spores, and the polyphyletic nature of the family of Mrazekiidae is obvious. Key words: Microsporidia, Mrazekia macrocyclopis sp.n., Copepoda, Macrocyclopsis albidus, ultrastructure, molecular phylogeny.
