Assessing the Competitive Ability of Rhynchosia capitata; an Emerging Summer Weed in Asia Planta Daninha
Ali,H.H.; Tanveer,A.; Naeem,M.; Jamil,M.; Iqbal,M.; Chadhar,A.R.; Kashif,M.S..
Rhynchosia capitata is a newly emerging threatening weed of summer crops in many Asian countries. We conducted 2-yr experiments to evaluate R. capitata competition with mungbean under irrigated conditions. Rhynchosia capitata was allowed to compete with mungbean for 0, 3, 4, 5, 6, 7 weeks after planting and for full crop season. The competitive ability of R. capitata was assessed by measuring its dry weight, micro and macro nutrient contents and uptake; and its effects on mungbean growth and yield parameters. The results showed that full season weed competition produced highest dry weight of R. capitata and its macro and micronutrient contents and uptake. Yield and yield components of mungbean decreased in a linear fashion with increase in competition...

Biological parameters of larvae, nymphs, and engorged females of Amblyomma cajennense (Fabricius, 1787) (Acari: Ixodidae) obtained from artificial and successive infestations on Oryctolagus cuniculus (Linnaeus, 1758) (Lagomorpha: Ochotonidae) Arq. Bras. Med. Vet. Zootec.
Freitas,C.M.V.; Leite,R.C.; Oliveira,P.R.; Fernández,F.C..
The development of acquired resistance to Amblyomma cajennense ticks was evaluated. A total of 18 rabbits were uniformly distributed into three groups named GL, GN, and GA that were submitted to three consecutive infestations with, respectively, larvae, nymphs, and adults of A. cajennense. After the infestations, the parasitic and reproductive parameters of recovered instars were evaluated. A significant reduction of recovery rates of inoculated ticks was observed only after the third infestation of animals in groups GL and GN (P<0.01). The modal day for drop-off of engorged larvae and nymphs increased along the infestations. The recovered engorged nymphs presented a significant reduction of the mean body weight between the first and the third...

Ecological relationships between feather mites (Acari) and wild birds of Emberizidae (Aves) in a fragment of Atlantic Forest in northeastern Brazil Zoologia
Lyra-Neves,Rachel M. de; Farias,Ângela M. Isidro de; Telino-Júnior,Wallace R..
The objective of this study was to investigate feather mites on birds of the Family Emberizidae, to collect data on the ecological ectoparasite-host relationship and infestation level. A sum of 94 birds of 9 species was captured at the Refúgio Ecológico Charles Darwin, Igarassú, Pernambuco, Brazil, from August 1996 to July 1997. Five genera of mites from the superfamily Analgoidea were identified: Analges Nitzsch, 1818; Mesalgoides Gaud &amp; Atyeo, 1967; Pterodectes Robin, 1877; Proctophyllodes Robin, 1877 and Trouessartia Canestrini, 1899. Among the 94 birds examined, 92 (97,87%) were infested. Regarding the prevalence, it was observed that the genera with higher percentage were, respectively, Pterodectes (88,04%), Proctophyllodes (56,52%) and...

Economics of Cogongrass Control in Slash Pine Forests AgEcon
Alavalapati, Janaki R.R.; Jose, Shibu; Stainback, G. Andrew; Matta, Jagannadha R.; Carter, Douglas R..
Cogonagrass (Imperata Cylindrica), an invasive weed, is a threat to slash pine forests. Using a dynamic optimization model, we estimated the impact of cogongrass on the profitability of slash pine forestry under four scenarios: no threat of cogongrass infestation; infestation is uncertain, and no control measures are taken; infestation is uncertain, but control measures are undertaken by one landowner but not the neighbors; and infestation is uncertain, and control measures are undertaken by everyone. Results indicate that annual net returns per acre under each scenario, respectively, are $25.30, $16.97, $13.89, and $17.38. Results suggest fostering a cooperative behavior among landowners is desirable.

Effect of olive fruit fly infestation on the quality of olive oil from cultivars cobrançosa, madural and verdeal transmontana IPB - Escola Superior Agrária
Pereira, J.A.; Alves, M.R.; Casal, S.; Oliveira, M.B.P.P..
Olives (Olea europaea L.) from cultivars Cobrançosa, Madural and Verdeal Transmontana were collected separately and divided into two different groups according to the presence or absence of infestation by the olive fruit fly (Bactrocera oleae Gmel.). These two groups were then mixed in varying percentages to create five groups of olives per cultivar with infestation levels: 0, 12.5, 25, 50 and 100%. Each group was then processed to produce olive oil. The results, regarding mainly acidity, peroxide value, and stability to oxidation, suggest that olive fruit fly infestation reduces the quality of the olive oil. The effects of infestation varied according to cultivar, but in general the total tocopherol content was always lower at the 100% infestation level....

Epibiosis in decapod crustaceans by stalked barnacle Octolasmis lowei (Cirripedia: Poecilasmatidae) Rev. Bras. Zool.
Machado,Glauco B. de O.; Sanches,Fabio H. C.; Fortuna,Monique D.; Costa,Tânia M..
Stalked barnacles Octolasmis lowei Darwin, 1851 are frequently found attached to decapod crustaceans. Their epibiotic association depends on many factors, which are mainly related to characteristics of the host's biology. This study evaluated the infestation and distribution of stalked barnacles in the branchial chambers of crabs, and analyzed the data with respect to the host's sex, maturity stage, molt cycle and size. The crab species Arenaeus cribrarius Lamarck, 1818, Callinectes danae Smith, 1869, Callinectes ornatus Ordway, 1863, Hepatus pudibundus Herbst, 1785, Libinia ferreirae Brito Capello, 1871, and Persephona punctata Linnaeus, 1758 were sampled and found to be infested by O. lowei. No juvenile crabs were infested. The prevalence of infestation...

Evaluation of the addition of ascorbic acid to the ration of cultivated Piaractus mesopotamicus (Characidae) on the infrapopulation of Anacanthorus penilabiatus (Monogenea) BJMBR
Martins,M.L..
Sixty Piaractus mesopotamicus Holmberg, 1887 (pacu) fry fed a diet containing 0, 50, 100 and 200 mg ascorbic acid/kg dry feed were studied to evaluate the effect on parasitic infestation by the monogenean Anacanthorus penilabiatus Boeger, Husak and Martins, 1995 (Monogenea: Dactylogyridae) for a period of 24 weeks. The temperature of the aquaria was measured daily and remained between 28 and 31oC. At the beginning of the experiment, fish showed 6.15 ± 0.33 cm standard length and 8.64 ± 1.62 g average body weight. A sample of fish was examined and showed 43 ± 17 monogeneans per fish. At the end of the experiment, the gills of control and vitamin C-treated fish were collected for parasite counts. Control fish had 42.5 parasites per fish, a significantly...

First record of Megaselia scalaris (Loew) (Diptera: Phoridae) infesting laboratory colonies of Triatoma brasiliensis Neiva (Hemiptera: Reduviidae) Neotropical Entomology
Costa,Jane; Almeida,Carlos E.; Esperança,Gleidson M.; Morales,Nínive; Mallet,Jacenir R. dos S.; Gonçalves,Teresa C.M.; Prado,Angelo P. do.
Megaselia scalaris (Loew) is a cosmopolitan and synanthropic scuttle fly, eclectic in its feeding habits and acts as detritivore, parasite, facultative parasite, and parasitoid. Here we report for the first time M. scalaris infesting laboratory colonies of Triatoma brasiliensis Neiva, the most important Chagas disease vector in semiarid areas of Brazil. M. scalaris larvae were found feeding inside bugs; pupae were found in the esophagus and intestinal regions of T. brasiliensis through dissection. Other relevant information about this finding is also described in this note, including some preventive measures to avoid laboratory colonies infestations.

Fumigant Toxicity of Crushed Bulbs of Two Allium Species to Callosobruchus maculatus (Fabricius) (Coleoptera: Bruchidae) Chilean J. Agric. Res.
Ofuya,T.I; Olotuah,O.F; Ogunsola,O.J.
Fumigant toxicity of crushed fresh bulbs of Allium sativum L. and A. cepa L. to the Callosobruchus maculatus (Fabricius), a major pest of stored cowpea (Vigna unguiculata (L.) Walp.) seeds was assessed under laboratory conditions in Akure, Nigeria. In the tests, 20 g of infested cowpea seeds were suspended in a piece of muslin cloth, over an amount of crushed bulb in a container with a tightly fitted lid. Adult emergence was completely prevented from freshly laid eggs of C. maculatus on cowpea seeds that was fumigated with 6.0 g or more of crushed bulbs of A. sativum. Such fumigated seeds were not holed at all. Other amounts of A. sativum tested (1.0, 2.0, 3.0, 4.0 and 5.0 g) significantly reduced C. maculatus adult emergence from fumigated eggs and seed...

Host plants of the carambola fruit fly, Bactrocera carambolae Drew &amp; Hancock (Diptera: Tephritidae), in Suriname, South America Neotropical Entomology
Sauers-Muller,Alies van.
Fruits were collected over a 12-year period to determine the host status for the Carambola fruit fly, Bactrocera carambolae Drew &amp; Hancock, and other tephritid species in Suriname, South America. Over 11,000 fruit samples were collected from many locations and the total of 20 fruit species were recorded as host, ranging in infestation from heavy to occasional. Over 650 samples of 188 fruit species, including many wild species, were collected and no fruit flies were reared. This work, which started specifically to obtain information on the Carambola fruit fly, resulted also in detailed information regarding the importance, distribution and host preferences of several Anastrepha species, and the status of fruit fly parasitoids.

Host-parasite interaction between crustaceans of six fish species from the Brazilian Amazon Biological Sciences
Vasconcelos, Huann Carllo Gentil; Tavares-Dias, Marcos.
Host-parasite interactions between crustaceans and six fish species (Psectrogaster falcata, Ageneiosus ucayalensis, Acestrorhynchus falcirostris, Hemiodus unimaculatus, Serrasalmus gibbus and Geophagus proximus) from a reservoir in eastern Amazon, northern Brazil, were investigated. Eight hundred and seventy-eight parasites belonging to three crustacean species, Excorallana berbicensis, Argulus chicomendesi and Ergasilus turucuyus, which parasitized the hosts’ mouth, gills and tegument, were collected from 295 fish and examined. High infestation levels were caused by E. berbicensis on the body surface of the hosts. Excorallana berbicensis showed aggregate dispersion, except in S. gibbus, while E. turucuyus showed random dispersion in A. falcirostris. The...

Incidência de Varroa destructor (Anderson & Trueman) em Criação de Abelhas com Ferrão na Região de Sinop, Mato Grosso, Brasil Ciências Agrárias
Torres, Rodrigo de Nazaré Santos; Barreto, Marliton Rocha.
Resumo. Quanto às enfermidades apícolas descreve-se que o Brasil está em situação vantajosa comparando com outros países, por apresentar enxames rústicos que, por serem mais resistentes a doenças, dispensam a utilização de antibióticos. Entretanto, a dinâmica de populações do ácaro Varroa mostrou ser muito diferente das outras regiões afetadas pela varroose sendo os primeiros índices registrados superiores a 20% e, ainda, se têm poucos trabalhos em relação à taxa de infestação em diferentes regiões do Brasil. Desta forma, este trabalho teve como objetivo realizar um levantamento de incidência do ácaro Varroa destructor (Anderson & Trueman) em colmeias na região de Sinop, MT. As coletas foram realizadas nos meses de julho e agosto de 2011 em oito...

O CNPGC realizou um experimento em quatro anos consecutivos (1991-1995). A cada ano, um rebanho de 120 vacas nelores, com bezerro ao pe, foi dividido em dois grupos, levando-se em consideracao as idades e os pesos das vacas e as idades dos bezerros. Durante a estacao de monta (novembro a fevereiro), foram mantidos tres touros, testados andrologicamente, em cada grupo. Em um dos grupos aplicaram-se inseticidas com intervalos que variavam com o principio ativo utilizado, em cada vaca e touro. Os dois grupos foram mantidos em piquetes separados, formados de Brachiaria decumbens, rotacionados a cada catorze dias, com uma taxa de lotacao de 1 UA/ha. As contagens da mosca nas vacas foram realizadas, tambem, a cada catorze dias. As vacas foram pesadas a cada dois...

Crassostrea gigas Thunberg's infestation by Mytilicola orientalis. Mori in 1979 in the basin of" Marennes-Oléron presents two maxima, one during spring, the other during autumn. The parasites have infested until 64 %of bred oysters.. The intensity of infestation la weak (93.5 %of oysters are infested by lass than six females) and depend on the hosts'size. By this fact, slgnificant impact appears only in spring and in winter. A middle infestation of more than three M. orientalis females seems to induce a significant decrease of rates of carbohydrates and of glycogen
