“…The market size of bio-pesticides increased 9.9% between 2005 and 2010. In the same period, the market size of synthetic pesticides decreased by 1.5% (Tanwar et al, 2012 ). For all crop types, bacterial bio-pesticides represent 74% of the market, fungal bio-pesticides represent approximately 10%, viral bio-pesticides 5%, predator bio-pesticides 8% and other bio-pesticides 3% (Thakore, 2006 ).…”

After more than 70 years of chemical pesticide use, modern agriculture is increasingly using biological control products. Resistances to conventional insecticides are wide spread, while those to bio-insecticides have raised less attention, and resistance management is frequently neglected. However, a good knowledge of the limitations of a new technique often provides greater sustainability. In this review, we compile cases of resistance to widely used bio-insecticides and describe the associated resistance mechanisms. This overview shows that all widely used bio-insecticides ultimately select resistant individuals. For example, at least 27 species of insects have been described as resistant to Bacillus thuringiensis toxins. The resistance mechanisms are at least as diverse as those that are involved in resistance to chemical insecticides, some of them being common to bio-insecticides and chemical insecticides. This analysis highlights the specific properties of bio-insecticides that the scientific community should use to provide a better sustainability of these products.

“…The release of biological control agents to manage pest populations has great potential, but only a few natural enemies could be massively grown at scale. In addition, the development of a natural enemy population is often slower than that of the target insect, usually requiring different conditions for optimal growth [8]. Currently, the existing biological control methods use pathogenic fungi, such as Beauveria bassiana, Metarhizium species [9] and bacteria Bacillus thuringiensis [10], with no biological control agents based on viruses.…”

The Colorado potato beetle (CPB) is one of the most serious insect pests with high ecological plasticity and ability to rapidly develop resistance to insecticides. The use of biological insecticides based on viruses is a promising approach to control insect pests, but the information on viruses, which infect leaf feeding beetles, is scarce. We performed the metagenomic analysis of 297 CPB genomic and transcriptomic samples from public NBCI SRA database. The reads that were not aligned to the reference genome were assembled with metaSPAdes and 13314 selected contigs were analyzed with BLAST tools. The contigs and non-aligned reads were also analyzed with Kraken2 software. 3137 virus-positive contigs were attributed to different viruses belonging to 6 types, 17 orders and 32 families, matching over 97 viral species. The annotated sequences can be divided into several groups: homologous to genetic sequences of insect viruses (Adintoviridae, Ascoviridae, Baculoviridae, Dicistroviridae, Chuviridae, Hytrosaviridae, Iflaviridae, Iridoviridae, Nimaviridae, Nudiviridae, Phasmaviridae, Picornaviridae, Polydnaviriformidae, Xinmoviridae etc.), plant viruses (Betaflexiviridae, Bromoviridae, Kitaviridae, Potyviridae), and endogenous retroviral elements (Retroviridae, Metaviridae). Also, the full-length genomes and near-full length genome sequences of several viruses were assembled. We have also found the sequences belonging to Bracoviriform viruses and for the first time experimentally validated the presence of bracoviral genetic fragments in CPB genome. Our work is the first attempt to discover the viral genetic material in CPB samples and we hope that further studies will help to identify new viruses to extend the arsenal of biopesticides against CPB.

“…Biopesticides are bioactive compounds that are metabolites of restricted distribution in the organism, produced by plants, animals, bacteria, and fungi, among other organisms, with potential use as pest control agents 8 , 9 . Biopesticides act by inhibiting or killing plant pathogens in closed areas, require minimal manipulation, are stable, and do not affect the environment 8 – 10 .…”

Fruit and vegetable crops that are not consumed immediately, unlike other agricultural products, require economic and time investments until they reach the final consumers. Synthetic agrochemicals are used to maintain and prolong the storage life of crops and avoid losses caused by phytopathogenic microorganisms. However, the excessive use of synthetic agrochemicals creates health problems and contributes to environmental pollution. To avoid these problems, less toxic and environment-friendly alternatives are sought. One of these alternatives is the application of biopesticides. However, few biopesticides are currently used. In this study, the biopesticide activity of Bursera morelensis and Lippia graveolens essential oils was evaluated. Their antifungal activity has been verified in an in vitro model, and chemical composition has been determined using gas chromatography-mass spectrometry. Their antifungal activity was corroborated in vitro, and their activity as biopesticides was subsequently evaluated in a plant model. In addition, the persistence of these essential oils on the surface of the plant model was determined. Results suggest that both essential oils are promising candidates for producing biopesticides. This is the first study showing that B. morelensis and L. graveolens essential oils work by inhibiting mycelial growth and spore germination and are environment-friendly biopesticides.
