Advances in gastropod immunity from the study of the interaction between the snail Biomphalaria glabrata and its parasites: A review of research progress over the last decade ArchiMer
Coustau, C.; Gourbal, B.; Duval, D.; Yoshino, T. P.; Adema, C. M.; Mitta, Guillaume.
This review summarizes the research progress made over the past decade in the field of gastropod immunity resulting from investigations of the interaction between the snail Biomphalaria glabrata and its trematode parasites. A combination of integrated approaches, including cellular, genetic and comparative molecular and proteomic approaches have revealed novel molecular components involved in mediating Biomphalaria immune responses that provide insights into the nature of host-parasite compatibility and the mechanisms involved in parasite recognition and killing. The current overview emphasizes that the interaction between B. glabrata and its trematode parasites involves a complex molecular crosstalk between numerous antigens, immune receptors, effectors...

Effect of Disinfectants and Pesticides Used in Poultry Houses on Beauveria Bassiana (Bals.) Vuill.fungus Rev. Bras. Ciênc. Avic.
Alves,LFA; Mamprim,AP; Formentini,MA; Martins,CC; Pinto,FG.
ABSTRACT This study aimed at evaluating the effect of the use of disinfectants and insecticides recommended for the control of pathogens and insects in poultry houses on the biological parameters of the entomopathogenic fungus Beauveria bassiana strain Unioeste 4. Disinfectants and insecticides were used at recommended concentration (RC), half the recommended concentration (0.5 RC), and twice there commended concentration (2RC). All treatments were sprayed on the fungus previously inoculated on PDA culture media. Germination, colony forming unit (CFU), vegetative growth and conidial yield were evaluated. Germination was the most affected parameter by insecticides, with reduction of up to 25% using Couro Limpo and Cypermil products. Cypermil also reduced...

Fasciola hepatica-Pseudosuccinea columella interaction: effect of increasing parasite doses, successive exposures and geographical origin on the infection outcome of susceptible and naturally-resistant snails from Cuba ArchiMer
Alba, Annia; Vazquez, Antonio A.; Sanchez, Jorge; Duval, David; Hernandez, Hilda M.; Sabourin, Emeline; Vittecoq, Marion; Hurtrez-bousses, Sylvie; Gourbal, Benjamin.
Background: Pseudosuccinea columella is one of the most widespread vectors of Fasciola hepatica, a globally distributed trematode that affects humans, livestock and wildlife. The exclusive occurrence in Cuba of susceptible and naturally-resistant populations to F. hepatica within this snail species, offers a fascinating model for evolutionary biology, health sciences and vector control strategies. In particular, resistance in P. columella is characterized by the encapsulation of the parasite by host's immune cells and has been experimentally tested using different Cuban F. hepatica isolates with no records of successful infection. Here, we aimed to explore for the first time, the effect of different parasite doses, successive exposures and different...

In vitro sensitivity of antagonistic Trichoderma atroviride to herbicides BABT
Santoro,Patricia Helena; Cavaguchi,Silvia Akimi; Alexandre,Talita Moretto; Zorzetti,Janaina; Neves,Pedro Manuel Oliveira Janeiro.
Trichoderma atroviride was tested in vitro for its sensitivity to different herbicides. The dosages tested were recommended dosage (RD), half dosage (½RD), and double dosage (2RD). Germination, colony-forming units (CFU), radial growth, and spore production were evaluated. Carfentrazone-ethyl and sulfentrazone inhibited the germination at RD and 2RD. A reduction in the CFU was observed for glufosinate-ammonium, atrazine, carfentrazone-ethyl, diuron + paraquat dichloride, imazapyr, oxyfluorfen, and sulfentrazone at each of the tested dosages. Radial growth was influenced by ametryn, atrazine, carfentrazone-ethyl, oxyfluorfen, and sulfentrazone herbicides, with an 80% reduction of the colonial area. Spore production was affected by carfentrazone-ethyl,...

Phytophthora infestans (Mont.) de Bary. I. Host-Pathogen specificity and resistance components Agrociencia
Lozoya-Saldaña,Héctor; Guzmán-Galindo,Leonel; Fernández-Pavia,Sylvia; Grünwald,Niklaus J.; McElhinny,Elaine.
Abstract The molecular identity of Phytophthora infestans strains infecting potatoes in the Toluca Valley has been documented. Nevertheless, the relationship of the P. infestans genotypes to the host’s genetic resistance is unclear. In order to identify potential host-pathogen specificity, isolates of the oomycete obtained from five potato varieties with differing levels of disease resistance were compared regarding mating type (MT), isozyme genotype for glucose-6-phosphate isomerase (Gpi) and peptidase (Pep), and sensitivity to metalaxyl. Also, host resistance components and specificity on the host-pathogen interaction were assessed twice in detached leaves in the laboratory and once in attached leaves in the greenhouse for three of the...

Population density of Beauveria bassiana in soil under the action of fungicides and native microbial populations Agronomy
Soares, Flávia Barbosa; Monteiro, Antonio Carlos; Babosa, José Carlos; Mochi, Dinalva Alves.
This study investigated whether populations of naturally-occurring soil bacteria, fungi and actinomycetes influence the effect of fungicides on the survival and growth of Beauveria bassiana. The toxicity of methyl thiophanate, pyraclostrobin, mancozeb and copper oxychloride at the recommended doses was analyzed in culture medium and in soil inoculated with fungus at various time points after addition of fungicides. All fungicides completely inhibited the growth and sporulation of B. bassiana in the culture medium. The fungicides were less toxic in soil, emphasizing the action of the microbial populations, which interfered with the toxic effects of these products to the fungus. Actinomycetes had the greatest influence on the entomopathogen, inhibiting it or...

RATIONAL INCOMPATIBILITY WITH INTERNATIONAL PRODUCT STANDARDS AgEcon
Barrett, Christopher B.; Yang, Yi-Nung.
This paper considers the incentives of firms to conform to an exogenous international product standard. Product standardization enables traditional, price-based international competition. But the existence of redesign costs or network effects creates market frictions that diminish the incentive to standardize if there already exists a different technology in an established market. This leads to multi-attribute competition between products and will generally reduce trade flows. Not only do incumbent firms using a different technology have an incentive to deviate from the international standard, but a host country government that is also concerned for the welfare of consumers who own the old technology has no incentive to enforce the international standard....

Stock-scion interactions on growth and rubber yield of Hevea brasiliensis Scientia Agricola
Cardinal,Átila Bento Beleti; Gonçalves,Paulo de Souza; Martins,Antônio Lúcio Mello.
Rubber tree cultivation [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell.-Arg.] uses mostly the budding propagation method, however the expected stand uniformity due to the use of vegetative propagation is theoretical, since high variation for yield and vigor is caused by rootstock influence. The objective of this study was to assess several combinations between clonal rootstocks and clone scions through diallel analysis, aiming at high productivity and vigor. Data consisted of five years of dry rubber yield and girth at panel opening from an experiment using a split-plot design with four replications, conducted at Pindorama, SP, Brazil, considering six rootstocks (GT 1, IAN 873, PB 235, RRIM 600, RRIM 701 and unselected seedlings) and six scions (GT 1,...

The Effects of Different Fungicides on the Viability of Entomopathogenic Nematodes Steinernema feltiae (Filipjev), S. carpocapsae Weiser, and Heterorhabditis downesi Stock, Griffin & Burnell (Nematoda: Rhabditida) under Laboratory Conditions Chilean J. Agric. Res.
Laznik,Žiga; Vidrih,Matej; Trdan,Stanislav.
To increase our knowledge on the susceptibility of entomopathogenic nematodes (EPN) species to agrochemicals, the compatibility of the infective juveniles (IJ) of the entomopathogenic nematodes Steinernema feltiae, S. carpocapsae, and Heterorhabditis downesi with 15 chemical fungicides was investigated under laboratory conditions. The effect of direct IJ exposure to fungicides for 24 h was tested in a petri dish at 15, 20, and 25 °C. The results showed that the compatibility of S. feltiae with azoxystrobin was high, and similar findings were obtained for S. carpocapsae (strain C67) and all of the tested fungicides, except for tebuconazole + spiroxamine + triadimenol, maneb, dinocap, and copper (II) hydroxide + metalaxil-M. Nematode H. downesi (strain 3173)...

Thermal and chemical characterization of Dicksonia sellowiana extract by means of thermal analysis. Repositório Alice
MALUCELLI, L. C.; MASSULO, T.; MAGALHAES, W. L. E.; STOFELLA, N. C. F.; VASCONCELOS, E. C.; CARVALHO FILHO, M. A. S.; MURAKAMI, F. S..
Dicksonia sellowiana Hook., Dicksoniaceae, is a tree-fern which is being recently used in medicine mainly for its phytotherapic activities. While several other studies have focused on D. sellowiana extract characterization in terms of its biological and antioxidant activity, the novelty of this work aims to understand the fate of this extract during thermal disposal through thermogravimetry/differential thermal analysis, thermogravimetry/mass spectrometry, Fourier transform infrared spectroscopy and elemental analysis, to further characterize this plant?s extract. Thermal analysis revealed mass loss within three welldefined steps, with the respective mass signals represented generated during heating. Light-volatiles were released during the first step,...

Two mistletoes are too many?: Interspecific occurrence of mistletoes on the same host tree Acta Botanica
Arruda,Rafael; Lunardelli,Caroline; Kitagawa,Clóvis; Caires,Claudenir Simões; Teodoro,Grazielle Sales; Mourão,Fabiana Alves.
Mistletoe can have a major impact on the fitness of the host plant. If there is more than one species of mistletoe on the same host tree, the overall impact might be amplified. We report the occurrence of more than one species of mistletoe on the same host tree. Although it is not a rule in the field, to our knowledge, there have been no studies of this topic. In most cases, two species of mistletoe were recorded on the same host tree, although we recorded three species of mistletoe on one occasion. This demonstrates that different species of mistletoe can be compatible with the same host species. Therefore, compatibility (structural and physiological) might be an important factor for the occurrence of mistletoe. Recent studies have shown that if the...
