Abstract Fumonisins are a family of hepatotoxic and nephrotoxic mycotoxins produced mainly by Fusarium verticillioides and F. proliferatum. F. proliferatum is an important pathogen colonizing an extraordinarily broad range of host plants worldwide and causing serious economic losses in agriculture, which has drawn our research attention. In order to manage F. proliferatum and its secondary metabolites in crop products and animal feed, the antifungal bacterium Serratia marcescens SerEW01 was isol...
Abstract Duddingtonia flagrans is a nematode-trapping fungus that is widely used to control parasitic nematodes in livestock. To investigate the features and advantages of D. flagrans for nematode control at the molecular level, the genome and transcriptome of D. flagrans were sequenced and studied through a comparative analysis. The genome of D. flagrans had a size of 36.3 Mb and contained a higher ratio of repetitive sequences, which revealed its slow evolution. Comparative genomics analysis r...
Abstract Apple Valsa canker (AVC), caused by the fungus Valsa mali (Vm), is a serious and persistent disease affecting apple production in China that is difficult to control chemically and agriculturally. In order to develop biological control agents (BCAs) for this disease, an antifungal activity-deficient Bacillus amyloliquefaciens mutant, ED-2544, was characterized using PCR amplification, Southern blotting, and SiteFinding-PCR. The B. amyloliquefaciens ChbB(chitin-binding proteins from B. am...
Abstract The cochineal, Dactylopius opuntiae (Hemiptera: Dactylopiidae) was first reported in Israel in 2013 in a restricted area in the upper Galilee from where, by 2018, it had spread throughout Galilee and the northern Coastal Plain. It infests and kills the Indian-fig prickly pear, Opuntia ficus-indica (Cactaceae), a prominent plant in the landscape of Israel and other Mediterranean countries. Inundative releases of industrially mass-reared Cryptolaemous montrouzieri (Coleoptera: Coccinellid...
Abstract The use of antagonists in the biocontrol of soilborne pathogens is a promising approach to manage many diseases. In this context, Bacillus velezensis strain OEE1, isolated from endogenous root tissue of olive trees, showed the most effective antifungal activity under in vitro conditions against V. dahliae with inhibition rate exceeding 92 % using the dual culture method to investigate effects of diffusible compounds. This antagonism was also demonstrated with volatile and extracellular ...
Abstract The consequences of infection by plant virus on the efficacy of parasitoid wasps are poorly understood. In the current study, an age-stage, two-sex life table and the CONSUME-MSChart computer program were used to test the performance of Encarsia formosa (Hymenoptera: Aphelinidae) on the whitefly, Bemisia tabaci Mediterranean (MED) species, occurring on healthy tomato plants compared to tomato plants infected with Tomato chlorosis virus (ToCV) and Tomato yellow leaf curl virus (TYLCV). T...
Abstract Ascorbic acid (vitamin C, Vc) is a well-known antioxidant, which can eliminate reactive oxygen species (ROS) in order to protect yeasts subjected oxidative stress. In our previous research, Pichia caribbica, one of the antagonistic yeasts showed an activity against postharvest diseases of apples, and Vc enhanced the tolerance to oxidative stress of P. caribbica, and improved its biocontrol efficacy to postharvest blue mold decay of apples. However, the mechanisms, especially the molecul...
Abstract Erythrina gall wasp, Quadrastichus erythrinae (Hymenoptera: Eulophidae) began a global range expansion around 2005, and is considered a significant adventive pest in Asia, Pacific islands, South- and Central America, and North America, including Hawaii. The Hawaii endemic wiliwili tree, Erythrina sandwicensis (Fabaceae) was severely impacted and threatened with extinction, leading to the release of a classical biological control agent, Eurytoma erythrinae (Hymenoptera: Eurytomidae) from...
Abstract This study determined the competitive saprophytic ability (CSA) of the hypovirulent isolate QT5-19 of Botrytis cinerea on potato dextrose agar (PDA) at 20°C. Meanwhile, importance of the QT5-19 CSA in biocontrol against virulent isolates of B. cinerea and Sclerotinia sclerotiorum (a close relative of B. cinerea), and the mechanisms for the QT5-19 CSA were elucidated. The results showed that QT5-19 had higher CSA than the virulent isolates 08168 (B. cinerea) and EP-1PNA367 (S. sclerotior...

Abstract The German cockroach, Blattella germanica (L.) is an indoor sanitary pest worldwide and seriously threatens human health. With the rapid development of insecticide resistance, biological control has gradually become the most promising strategy for cockroach control. In this review, we focus on the latest advances in the use of following materials for biocontrol of the German cockroach: entomopathogenic bacteria, fungi, viruses, natural enemies, nematodes and plant-derived substances, pl...
