Does host plant quality constrain the performance of the Parthenium beetle Zygogramma bicolorata?
This study assessed the influence of high, medium and low host plant quality, as influenced by fertiliser application, on the survival, development and fecundity of Z. bicolorata. Although egg to adult survival was high (∼80%) and did not differ between plant quality treatments, larvae developed fastest on plants of high and medium quality. Larval feeding was highly damaging, reducing the growth, reproduction and biomass of P. hysterophorus in all three plant quality treatments. Fecundity was associated with plant quality, with larger, more fecund females developing on higher quality plants. Overall, this research may ...

Organic farms conserve a dung beetle species capable of disrupting fly vectors of foodborne pathogens
We examined the possible implications for food safety of interactions between O. taurus and a common fly species on the farms, Calliphora vomitora, in microcosms containing pig (Sus scrofa) feces inoculated with human pathogenic E. coli O157:H7 and placed near broccoli (Brassica oleracea) plants. In the absence of dung beetles, Calliphora vomitora readily acquired the bacteria and transmitted them to broccoli foliage. In the presence of the dung beetle O. taurus, however, E. coli in the soil and fly survivorship were reduced, and the pathogen was rarely recovered from foliage. Altogether, our ...

Bio-protection of brown spot disease of rice and insight into the molecular basis of interaction between Oryza sativa, Bipolaris oryzae and Bacillus amyloliquefaciens
Publication date: Available online 2 July 2019Source: Biological ControlAuthor(s): S.R. Prabhukarthikeyan, Manoj K Yadav, A. Anandan, Aravindan, U. Keerthana, S. Raghu, Mathew S Baite, C. Parameswaran, P. Panneerselvam, PC. RathAbstractThe aim of the study is to evaluate the efficacy of Bacillus amyloliquefaciens strain BS5 against brown spot disease of rice and to understand the molecular mechanism of host-pathogen-bioagent interactions through a proteomic approach. We tested the antagonistic potential of forty Bacillus spp. against Bipolaris oryzae under in vitro. Based on their antagonism, ten effective strains were sel...

The combined use of the antagonistic yeast Hanseniaspora uvarum with β-aminobutyric acid for the management of postharvest diseases of kiwifruit
Publication date: Available online 2 July 2019Source: Biological ControlAuthor(s): Lilin Cheng, Xiaobao Nie, Changxing Jiang, Songlin LiAbstractSignificant losses in harvested kiwifruit can be directly attributed to decay fungi. In the present study, the use of an antagonistic yeast, Hanseniaspora uvarum, combined with β-aminobutyric acid (BABA), a non-proteinogenic amino acid, was evaluated as a treatment for controlling postharvest infections of kiwifruit, artificially-inoculated with either Botrytis cinerea or Alternaria alternata. Natural infection of treated kiwifruits was also assessed. H. uvarum or BA...

Laboratory evaluation of predation of Toxorhynchites amboinensis (Diptera:Culicidae) on three mosquito vectors of arboviruses in the Philippines
Publication date: October 2019Source: Biological Control, Volume 137Author(s): Jonathan R. Digma, Augusto C. Sumalde, Cristina C. SalibayAbstractThe spread of arboviral disease in the Province of Cavite, Philippines has resulted to the declaration of state of calamities which has led to higher disease burden and economic costs for the province and its population. With this situation, the use of biological control agents like the naturally occurring non - hematophagous Toxorhynchites species with predatory capacity at its larval stage was explored as an alternative approach to environmentally degrading chemical insecticides...

Postharvest biocontrol of anthracnose in bananas by endophytic and soil rhizosphere bacteria associated with sisal (Agave sisalana) in Brazil
Publication date: Available online 28 June 2019Source: Biological ControlAuthor(s): Caroline Lopes Damasceno, Elizabeth Amélia Alves Duarte, Lorena Brito Pimentel Rodrigues dos Santos, Thiago Alves Santos de Oliveira, Fabio Nascimento de Jesus, Lenaldo Muniz de Oliveira, Aristóteles Góes-Neto, Ana Cristina Fermino SoaresAbstractBanana is one of the most consumed fruits worldwide and a climacteric tropical commodity that requires harvesting methods, storage and transportation, which burden its marketing. It is one of the food crops most susceptible to diseases, such as anthracnose caused by Colletotrich...
