The use of nanoparticles (NPs) has generated an alternative pest control. The objective was to evaluate the insecticidal effect of zinc oxide nanoparticles (ZnO NPs), titanium dioxide nanoparticles (TiO2 NPs), and their combination on Bactericera cockerelli (Hemiptera: Triozidae) second-stage nymphs under laboratory and greenhouse conditions in tomato. The laboratory research was carried out with the leaf immersion bioassay method under a complete randomized design, and in the greenhouse by direct plant spraying under a randomized block design; in both designs, a control without NPs was added. Mortality was recorded every 24 h for 4 days. Both NPs in the laboratory and greenhouse showed toxicity to B. cockerelli nymphs. Results in the laboratory showed that NPs significantly caused increased mortality of 88, 99, and 100% 96 h after treatment of ZnO NPs, TiO2 NPs, and their combinations, at 1000, 100, and 250 ppm, respectively. Direct spray of plants in the greenhouse showed low mortality with 27, 32, and 23% after 96 h of ZnO NPs, TiO2 NPs, and their combinations, at 3000, 500, and 250 ppm, respectively. These results on B. cockerelli control seem promising. Nanoparticles as insecticides are a novel strategy, however, further investigation is required in field tests to obtain suitable efficacy for use in a pest management system.

The present study is carried out to establish the biofortification of zinc in potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.) plants through the application of zinc oxide nanoparticles (ZnONPs). The mycogenic ZnONPs are synthesized by using Aspergillus flavus biomass and characterized to ascertain the size, shape, and concentration of synthesized nanoparticles. The ZnONPs are applied by foliar spray to the field-grown potato and tomato crops and the biofortification level is recorded by Atomic Absorption Spectroscopy (AAS). A nanotoxicity assessment is done by comparing the amount of cell death and accumulation of reactive oxygen species (ROS) in control and ZnONPs treated plants. The AAS analysis reveals significant accumulation of the zinc in leaves of potato plants but insignificant accumulation is observed in the tubers. However, a significant accumulation of zinc is observed in the leaves and fruits of the tomato plants (p ≤ 0.05). The nanotoxicity evaluation studies show comparable and statistically insignificant toxicity in control plants as compared to plants treated with ZnONPs. The study concludes that biofortification through the means of ZnONPs is a cost-effective and eco-friendly approach that can be used as an alternative to the hazardous chemical zinc fertilizers.

“…AgNPs, with synthesis, exhibited larvicidal efficacy against Anopheles stephensi, utilising aqueous extracts Solanum nigrum dry leaves, fresh leaves and beans (Thandapani et al, 2018). Synthesized AgNPs utilising Azadirachta indica (Neem) aqueous leaf extracts showed larvicidal, pupicidal, and adulticidal activities against the vector of filariais, Anopheles stephensi and filariais vector Culex quinquefasciatos (Selvarani et al, 2016) (Shukla et al, 2020).…”

Resistance and insufficient attention to the applicable standards are typical explanations of pesticide treatment failure to insecticide resistance such as organophosphates and control agents. There is therefore a need for a safer, cheaper and more efficient investigation of mosquito control agents with new modes of actions. Recently, biologically produced nanoparticles have been seen as a possible strategy to fighting malaria vectors and also as a therapy for mosquito illnesses. Here we provide current understanding on the efficacy of biogenic nanoparticles (NPs) in vector-borne conditions.
