“…Rouhani et al. () found that AgNPs were toxic to the oleander aphid, Aphis nerii , a pest of some ornamental plants. They compared the LC 50 values of the nanoparticles and a neonicotinoid insecticide, imidacloprid, finding the aphids were far more susceptible to the insecticide than the AgNPs.…”

Silver nanoparticles (AgNPs) have antimicrobial and insecticidal properties and they have been considered for their potential use as insecticides. While they do, indeed, kill some insects, two broader issues have not been considered in a critical way. First, reports of insect-lethal AgNPs are often based on simplistic methods that yield nanoparticles of nonuniform shapes and sizes, leaving questions about the precise treatments test insects experienced. Second, we do not know how AgNPs influence beneficial insects. This work addresses these issues. We assessed the influence of AgNPs on life history parameters of two agricultural pest insect species, Heliothis virescens (tobacco budworm) and Trichoplusia ni (cabbage looper) and a beneficial predatory insect species, Podisus maculiventris (spined soldier bug), all of which act in agroecosystems. Rearing the two pest species on standard media amended with AgNPs led to negligible influence on developmental times, pupal weights, and adult emergence, however, they led to retarded development, reductions in adult weight and fecundity, and increased mortality in the predator. These negative effects on the beneficial species, if also true for other beneficial insect species, would have substantial negative implications for continued development of AgNPs for insect pest management programs.

“…In the comparison made between acaricidal, licicidal and larvicidal activities of zinc oxides and the synthesized ZnO nanoparticles, the mortality effect of ZnO nanoparticles was significant (Kirthi et al, 2011). Rouhani et al (2012) (Burckhardt and Lauterer, 1989)) and found out a greater insecticidal effect of Amitraz than the above nanoparticles. It should be taken into consideration that nanoparticles, especially the synthesized zinc nanopartilces, besides their insecticidal activity and also their slower effect than imidacloprid and Amitraz insecticides, have a lower risk of resistance to these nanoparticles in comparison to commercial insecticides .…”

“…Application of nanomaterials can revolutionize agriculture by developing potential and effective methods for pest management (Rai and Ingle, 2012). Some studies have reported the toxic effects of metal nanoparticles (such as silver, zinc, aluminum, and titanium oxide) on plants, crustaceans, bacteria, fungi, pathogens and pests (Elchiguerra et al, 2005;Goswami et al, 2010;Kairyte et al, 2013;Kirthi et al, 2011;Manzo et al, 2011;Morones et al, 2005;Reddy et al, 2007;Rouhani et al, 2012;Samuel and Guggenbichler 2004). Among them, zinc oxide (ZnO) nanoparticle is best-known compound (Mitra et al, 2012) commonly used as agricultural fungicide (Waxman 1998).…”

Greenhouse whitefly, Trialeurodes vaporariorum is a major pest of horticultural and ornamental plants and is usually controlled with insecticides or biological control agents. In the current study, we examined the effects of synthesized zinc oxide nanoparticles (ZnO NPs) and Beauveria bassiana TS11 on T. vaporariorum adults. ZnO NPs were synthesized by precipitation method. Field emission scanning electron microscope images indicated that ZnO NPs were noncompacted uniformly. X-ray diffraction results confirmed the hexagonal wurtzite structure of ZnO NPs. Fourier transform infrared analysis showed an intense absorption peak at a range of 434-555 cm -1 related to Zn-O bond. In bioassays, adults were exposed to different concentrations of ZnO NPs (3, 5, 10, 15, 20 , 10 7 , 10 8 spor ml -1 ). Vrednosti LC 50 so bile za nano delce ZnO 7.35 mg l -1 in 3.28×10 5 ml -1 za trose glive. Smrtnost, ki je bila dosežena pri največjih koncentracijah nano delcev ZnO in trosov glive je znašala 91.6 % in 88.8 %. Ti izsledki kažejo pozitivni učinek obeh pripravkov na smrtnost odraslih osebkov rastlinjakovega ščitkarja. Glede na to, da je bila raziskava opravljena v laboratoriju je potrebno v bodoče opraviti še več raziskav v realnih razmerah.

Nanoagrochemicals, such as nanopesticides, nanofertilizers or plant growth stimulating nanosystems, were primarily designed to increase solubility, enhance bioavailability, targeted delivery, controlled release and/or protection against degradation resulting in the reduced amount of applied active ingredients and finally in a decrease of dose-dependent toxicity/burden. This paper is a comprehensive up-to-date review related to the preparation and the biological activity of nanoformulations enabling gradual release of active ingredient into weeds and the body of pests and controlled release of nutrients to plants. The attention is also devoted to the decrease of direct environmental burden and economic benefits due to application of nanoformulations, where less amount of active ingredient is needed to achieve the same biological effect in comparison with bulk. The application of nanotechnology in the areas such as food packaging, food security, encapsulation of nutrients and development of new functional products is analysed. The use of nanoparticles in biosensors for detection of pathogens and contaminants as well as in DNA and gene delivery is discussed as well. Benefits and health risks of nanoagrochemicals are highlighted, and special attention is given to nanoecotoxicology and guidelines and regulatory documents related to the use of nanoformulations in agriculture and food industry.
