Siderophore containing extract from Serratia plymuthica AED38 as an efficient strategy against avocado root rot caused by Phytophthora cinnamomi Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-11-21 Sara Ramírez Restrepo; Cristina Calle Henao; Lina María Arbeláez Galvis; Juan Carlos Bedoya Pérez; Rodrigo Alberto Hoyos Sánchez; Sinar David Granada García
ABSTRACT Phytophthora cinnamomi Rands. is a widely distributed pathogen in avocado crops. Root rot caused by Phytophthora cinnamomi decreases the yield and growers are to establish new productive areas in order to meet demand which in turn is causing the loss of native forests. Therefore, sustainable production of avocado is only possible by addressing yield issues and the efficient use of lands. In

Assessment of the efficacy in vitro of Duddingtonia flagrans isolate 03/99 in different doses of chlamydospores and faeces egg counts in faecal of sheep Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-11-21 María Federica Sagües; Sara Zegbi; Inés Guerrero; Silvina Fernández; Lucía Iglesias; Milagros Junco; Carlos Saumell
ABSTRACT The oral application of chlamydospores of the nematophagous fungus Duddingtonia flagrans allows reducing the number of infective larvae (L3) in faeces and decreases the infectivity of the pastures of gastrointestinal nematodes. There are differences in the literature about the quantity of chlamydospores required for the reduction of L3 and there is little data about the importance of the concentration

A review of the in vitro liquid mass culture of entomopathogenic nematodes Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-10-26 Murray D. Dunn; Prasanna D. Belur; Antoinette P. Malan
ABSTRACT Entomopathogenic nematodes (EPNs) are a safe insect biological control agent. Key to the implementation of EPNs as a biopesticide is their mass production in shake flasks and bioreactors. For commercial application, in vitro liquid culture is the predominant choice, due to the cost and scale of production, and to the ease of downstreaming. The in vitro liquid culture of EPNs begins in Erlenmeyer

Application of isomelezitose as an osmoprotectant for biological control agent preservation during drying and storage Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-10-15 Patricia J. Slininger; Gregory L. Côté; Maureen A. Shea-Andersh; Bruce S. Dien; Christopher D. Skory
ABSTRACT Isomelezitose (IMZ) is of interest as a potential osmoprotectant, but it has not been previously characterised even though the structurally similar trisaccharide melezitose has been previously shown to have excellent protective qualities. The recent discovery that sucrose can be converted to IMZ during glucansucrase reactions suggests that IMZ might become an economical choice as an osmoprotectant

First drone releases of the biological control agent Neomusotima conspurcatalis on Old World climbing fern Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-10-14 Ellen C. Lake; Aaron S. David; Thomas M. Spencer; Victor L. Wilhelm Jr; Travis W. Barnett; Anwar A. Abdel-Kader; Andrea Carmona Cortes; Adrian Acuna; Elizabeth D. Mattison; Carey R. Minteer
ABSTRACT Biological control is a sustainable method of weed management because agents can establish persistent and self-dispersing populations on a landscape scale. Strategic releases are often conducted to accelerate the widespread dispersal and establishment of agents. Drones (unmanned aerial systems, UAS) could facilitate these releases, particularly in remote areas that are difficult or dangerous

Effects of maize pre-cultivation on soil deterioration indicated by the soil nematode community in replanted apple orchard Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-07-16 Ye-qing Yang; Qi-zhi Liu
Maize pre-cultivation was hypothesised to alleviate soil deterioration in replanted apple orchard, and this would be expected to be reflected in the nematode community in the soil. To test this hypothesis, soil parameters and nematode population composition were measured. Compared with replanted apple treatment, soil pH, soil organic matter, ammonium nitrogen and the available P and K content of the

A practical guide for managing a self-sustaining colony of Deroceras reticulatum (Müller) (Mollusca: Pulmonata) Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-07-15 Helen Billman-Jacobe; Anne Watt; Denya Heap; Ruth Haites
Deroceras reticulatum also known as the Grey Field Slug is a serious agricultural and horticultural pest. Integrated pest management of D. reticulatum and other pest molluscs includes the use of chemical mollusicides, crop management practices and biological control. Research into the biology and control of D. reticulatum requires animals for experiments; however, collection of wild animals for these

Mycoherbicide potential of Alternaria alternata (Fries.) Kiessler and its formulations on the host weed Xanthium strumarium L. Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-09-02 Nesma Abdessemed; Youssef Anis Bahet; Nadjia Zermane
ABSTRACT This study evaluated the mycoherbicidal potential of Alternaria alternata (Fries.) Kiessler on cocklebur (Xanthium strumarium L.), a noxious weed in Algeria. Conidial suspension, a rapeseed-oil-based liquid formulation and a sodium-alginate-based solid formulation, all with 106 conidia/ml, as well as the herbicide (Mustang®) at a reduced dose (0.45 L/ha) were compared. Inoculum was applied

Interactions among biological control agents on waterhyacinth: impacts of herbivory on the oviposition and development of Megamelus scutellaris Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-08-10 A. B. C. Goode; B. K. Knowles; P. W. Tipping; J. R. Foley; L. A. Gettys
ABSTRACT Multiple biological control agents have been developed and released to increase control and reduce treatment costs of Pontederia (Eichhornia) crassipes in Florida. Although two species of weevil (Neochetina eichhorniae and Neochetina bruchi) and the planthopper (Megamelus scutellaris) utilise P. crassipes for feeding and reproduction, little is known about their interactions including any

Pepper growth promotion and Fusarium wilt biocontrol by Trichoderma hamatum MHT1134 Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-08-07 Tingting Mao; Xiaojun Chen; Haixia Ding; Xiaoyulong Chen; Xuanli Jiang
ABSTRACT Pepper wilt, caused by Fusarium oxysporum, is an important disease of pepper in many regions of the world. A phosphate solubilising Trichoderma strain MHT1134 was selected from 76 isolates from the pepper rhizosphere as a potential biological control agent against wilt disease caused by F. oxysporum. The inhibitory rate of MHT1134 against F. oxysporum was 81.80%. MHT1134 was identified as

First report on the entomopathogenicity and virulence of Akanthomyces muscarius LY 72.14, a Yungas native fungal isolate, for Anastrepha fraterculus control Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-08-03 Mariana E. Danilovich; Sergio M. Ovruski; Julia I. Fariña; Osvaldo D. Delgado
ABSTRACT In this work, we report the entomopathogenic potential of Akanthomyces muscarius LY72.14, a fungus isolated from a soil sample collected in the Southernmost sector of Las Yungas (Tucumán, Argentina) subtropical rainforest. The isolated fungus exhibited both pathogenicity and virulence in larvae, pupae and adults of the pestiferous fruit fly Anastrepha fraterculus, ability that could then be

Growth phase-dependent nematocidal activity of Bacillus thuringiensis strains from natural samples Biocontrol Sci. Technol. (IF 1.215) Pub Date : 2020-08-01 Iva Atanasković; Djordje Marjanović; Saša Trailović; Djordje Fira; Slaviša Stanković; Jelena Lozo
ABSTRACT Natural isolates coming from chemically untreated environmental samples can be a source of new nematocidal bacterial strains. Little is known about the abundance of such isolates; the diversity of nematocidal proteins that they produce, or how their nematocidal activity changes in a growth phase-dependent manner. In this study, a collection of 17 Bacillus thuringiensis (Bt) natural isolates
