“…Other nano-formulations enhanced the activity of the acetylcholine esterase and glutathione S-transferases (Milivojevic et al 2015). The inhibition of the protease actions had been found because of the AgNPs (Kantrao et al 2017). The protease inactivation was occurred due to the electrostatic and hydrophobic interaction which further endorsed the protease adsorption on the NP surface that can convert the biological actions of the enzyme, for example, by impairing the binding with the substrate (Shahzad and Manzoor 2021).…”

Background Recent concerns linked with the application of chemical pesticides and the increasing necessity of low inputs sustainable agriculture have put the use of microbial biocontrol agents and bio-pesticides to the forefront for their application against plant pathogens and insect–pest management. Results This review tended to scrutinize the prospects of microbial biocontrol agents and microbes-based nano-formulations against plant diseases and for pest management with emphasis on bacteria-based nanoparticles, especially derived from Bacillus species. It also tended to discuss the probable mechanism of action and effect on plant growth along with its prospects in a brief manner. Conclusion The use of microbial biocontrol agents offers effective, eco-friendly, and long-lasting management of plant diseases. The employment of nanotechnology in the field of biopesticides has emerged as a promising solution. Nano-biopesticides in the form of biologically derived active pesticides or compounds integrated as nanoparticles and integrated into a suitable polymer have application in insect–pest management.

“…are being explored for the control of several crop insect pests, including sap-sucking pests such as aphids, and whitefly. The potential of nanoparticles is largely tested in two different ways (i) nanomaterials themselves used as pesticides [ 168 , 169 ], (ii) as additives to enhance the toxicity of currently available natural/synthetic insecticidal oil and formulations, etc. [ 170 ].…”

Whiteflies are a group of universally occurring insects that are considered to be a serious pest in their own way for causing both direct and indirect damages to crops. A few of them serve as vectors of plant viruses that are detrimental to the crop in question and cause an actual loss in productivity. A lot of attention is focused on pest control measures under the umbrella of IPM. In this review, we attempt to summarize the existing literature on how and why whiteflies are a serious concern for agriculture and society. We reviewed why there could be a need for fresh insight into the ways and means with which the pest can be combated. Here, we have emphasized next-generation strategies based on macromolecules, i.e., RNA interference and genetic engineering (for the expression of anti-whitefly proteins), as these strategies possess the greatest scope for research and improvement in the future. Recent scientific efforts based on nanotechnology and genome editing, which seem to offer great potential for whitefly/crop pest control, have been discussed. Comprehensive apprehensions related to obstacles in the path of taking lab-ready technologies into the farmers’ field have also been highlighted. Although the use of RNAi, GM crops, nanotechnologies, for the control of whiteflies needs to be evaluated in the field, there is an emerging range of possible applications with promising prospects for the control of these tiny flies that are mighty pests.

The European Commission has recognized nanotechnologies as extremely promising for increasing competitiveness of different sectors of the economy. On account of climate changes and the quest for food security, they are an effective way of solving key problems in the agrarian sector. Nowadays nanotechnologies are widely used for creating nanofertilizers, nanoinsecticides, nanofungicides, nanoherbicides and other nanopreparations. Numerous researches affirm advantages of nanopreparations, which has helped them find a wide use in agricultural practice. At the same time, nanopreparations are the source of entry into the environment of nanoparticles (size less than 100 nm) which are characterized by large active surface and specific physical-chemical properties different from ordinary chemical substances. It is precisely this which determines their bioaccessibility, bioaccumulation and toxicity. Recently, data about toxicity of nanoparticles for human and natural ecosystems have been accumulated. The results of a great deal of research affirm that they break the processes of photosynthesis, transpiration, mitosis, miosis and have a negative influence on colouring agents, proteins and carbohydrates. Under their action, physiological processes of plant growth and development are disturbed, which take place mainly in root system. Nanoparticles are characterized by high bioaccessibility for soil organisms, they are toxic to earthworms and microorganisms and they influence circulation of carbon and nitrogen. Aquatic organisms have been shown to have high sensitivity to nanoparticles; toxic effect has been registered for fish, daphnids, water plants and microorganisms. Taking into consideration the high level of potential danger of nanopreparations used in crop cultivation, special notice should be paid to the development of eco toxicological research. At present, nanoecotoxicological approaches to assessment of the danger of nanomaterials and nanoparticles are absent. Development of reports on elaboration of quantitative and qualitative methods of analysis, and methods of modeling and prognostication of risks is only at the initial stage. The objective of this review is attracting attention to solving the problem of nanoecotoxicology, nanoagrochemicals and nanopesticides, which needs consolidated efforts of scientists, governmental organizations and business and is an obligatory condition for preventing the negative impact of nanomaterials on humans and the environment.
