TL;DR: This review presents a detailed illustrated overview on current encapsulation methods that are applied or that may be tailored to living biological control agents, especially microbial organisms and entomopathogenic nematodes.

TL;DR: Only Lactobacillus fermentum CRL 251 produced fungus inhibitory peptide/s, smaller than 10 kDa, thermostable, active in the pH range of 4–7 and sensitive to trypsin, the first report on antifungal peptides produced by a L. fermentum strain.

TL;DR: An overview of information about the influence of Trichoderma on the diversity of systemic resistance induction in plants and the possible development of this process is presented.

TL;DR: Progress that has been made in the development and implementation of biological controls for rice in China since the 1970s is reviewed, which includes the species identification of the natural enemies of rice insect pests, the characterization of their biology, and the integration of biological control in integrated pest management.

TL;DR: Results indicate that in Arabidopsis Ps14 and Tr6 activate the same signaling pathway and thus have no enhanced effect in combination, and the enhanced protection in cucumber by the combi- nation is most likely due to activation of different signaling pathways by the two biocontrol agents.

TL;DR: The results showed that H. dimidiata is a more efficient biological control agent for A. gossypii at 20 and 25 °C than at 15 °Cs, when both the growth rate and the predation rate were considered.

TL;DR: The results showed that the two screened antagonistic bacteria, and some of their produced volatiles and artificial mixtures could be promising control methods for anthracnose in harvested mango fruit.

TL;DR: There is potential for well-orchestrated regional research projects to pursue higher levels of CBC integration into current pest management schemes, and a first step in drawing a roadmap for developing-world research that provides local farmers with safe, low-cost means to control damaging insect pests, safeguard harvests and secure their livelihoods.

TL;DR: Results suggest that the CWDEs NAGase and β-1,3-glucanase and sclerotia parasitism are key components of Trichoderma spp.

TL;DR: The results indicate that I. fumosorosea CG1228 has desirable attributes for the development of a mycoinsecticide against whitefly nymphs and adults as well as attained high spore production on insect cadavers and parboiled rice.

TL;DR: Two strains of Bacillus sp.

TL;DR: The combination of the different action mechanisms of the yeast increases their ability to control C. gloeosporioides and may contribute to the integrated management of disease caused by this pathogen.

TL;DR: It is shown that mosquitoes have a preference to lay eggs in tadpole water and that tadpoles destroy such eggs laid, and direct observations substantiate that all tadpole species tested are mosquito egg predators.

TL;DR: This study demonstrates the growing importance of applying genomic-based studies to biocontrol organisms of plant pathogens which can enable the rapid identification of bioactive metabolites produced by a prospective biological control organism.

TL;DR: Management of vineyards where non-crop vegetation can be used to increase numbers and impact of beneficials are suggested, with recommendations for planting woody vegetation a minimum of 50 m from vineyard edges.

TL;DR: The floral resources that sweet alyssum plants provided attracted natural enemies and indirectly suppressed densities of woolly apple aphids, suggesting an effective means for apple growers to enhance biological control.

TL;DR: The impact of non-host resources on host-parasitoid interactions and the potential for using selective food resources in conservation biological control of the exotic pest T. absoluta are explored.

TL;DR: Results show that honeydew of cabbage aphids ( Brevicoryne brassicae) strongly enhances hoverfly survival in the absence of floral resources, and Cage experiments show that when suitable flowers are present the hoverflies can strongly suppress the growth of cabbage Aphid colonies on Brussels sprouts.

TL;DR: Evidence is provided that naturally growing weeds in chili pepper agroecosystems can affect aphid natural enemy abundance and survival, highlighting the need for further research to fully characterize the structure and function of plant resources in these and other tropical agroECosSystems.

TL;DR: There was sufficient abundance of suitable prey to sustain epigeal spider populations in winter wheat such that they were available to prey on pests during immigration into the crop, and linyphiid spiders have the potential to play an important role in suppressing early-season aphid populations.

TL;DR: It is shown that sesame has a marked beneficial effect on key parameters of Anagrus spp.

TL;DR: The suitability and effectiveness of the predatory bug Dicyphus errans (Wolff) (Hemiptera: Miridae), an indigenous species usually found in the IPM tomato crop of northwestern Italy, were evaluated on eggs and larvae of T. absoluta under controlled conditions and can be considered a promising potential candidate for controlling the pest.

TL;DR: This research provides the first information on a novel additive intercropping approach to provide alyssum floral resource s for biological control of lettuce aphids, and suggests that this approach may be a more land-efficient particularly for producing smaller lettuce heads for romaine hearts or for markets with less strict size requirem ents.

TL;DR: In this article, the influence of five rhizospheric microbes, namely Bacillus megaterium, Pseudomonas fluorescens (ATCC No. 13525), Trichoderma viride, Paecilomyces lilacinus (PDBC PL55), and Glomus intraradices, was studied for the management of M. incognita in W. somnifera cv. Poshita under greenhouse conditions.

TL;DR: In this paper, a root weevil pest of citrus, Diaprepes abbreviatus, is more damaging and attains higher population density in some orchards on fine textured, poorly drained “flatwoods” soils than in those on the deep, coarse sandy soils of the central ridge.

TL;DR: Fusaric acid (FA) was identified as the major metabolite in culture filtrate of the phytopathogenic F. oxysporum strain ITEM 2797 (Fo2797) and totally inhibited the growth of Th908 on PDA containing 120 μg of FA per gram in 3-day trials.

TL;DR: Isolates BC1AW and PP3WT significantly reduced bacterial wilt incidence in tomato genotypes King Kong 2 and L390 in the pot experiments and in split root experiments, and were selected as promising biocontrol isolates whose effectiveness under field conditions and mode of action at molecular level should be investigated.

TL;DR: This is the first report of the evaluation of the inhibitory effects of C. globosum and chaetoglobosin A against S. turcica both in vitro and on detached maize leaves.

TL;DR: The ability of the bird cherry-oat aphid to detect one of its important predators, seven spot ladybird, via chemicals in the predator’s walking track is investigated, suggesting that aphids may be able to assess the risk of predation via the extent of the chemical tracks and adjust their behavioral response accordingly.
