“…Numerous studies have indicated that silicon application can reduce the performance of sap-feeding pest insects as green bug Schizaphis graminum Rondani (Hemiptera: Aphididae) on sorghum (Carvalho et al, 1999), whitefly Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae) on cucumber (Correa et al, 2005), and on soybean (Ferreira et al, 2011) green peach aphid Myzus persicae Sulzer (Hemiptera: Aphididae) on potato (Gomes et al, 2008), spittlebug Mahanarva fimbriolata Stal (Hemiptera: Cercopidae) on sugarcane (Korndorfer et al, 2011), Silvering thrips Enneothrips flavens Moulton (Thysanoptera: Thripidae) on peanut (Dalastra et al, 2011), Mediterranean fruit fly Ceratitis capitata Wiedemann (Diptera: Tephritidae) on lemon (Mditshwa et al, 2013), mealy-bug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) on Portulaca grandiflora plants (Huang et al, 2014), brown plant-hopper Nilaparvata lugens Stal (Hemiptera: Delphacidae) on rice (He et al, 2015), leaf aphid Rhopalosiphum maidis Fitch (Hemiptera: Aphididae) on maize (Almeida et al, 2015), and citrus black-fly Aleurocanthus woglumi Ashby (Homoptera: Aleyrodidae) on mandarin orange (Vieira et al, 2016). Positive effects of silicon treatment were evident as reduced preference, longevity and fecundity rates, nymph production-and feeding times by nymphs of green bug Schizaphis graminum (Rondani) (Hemiptera: Aphididae) on wheat (Costa et al, 2011).…”

The emerging role of silicon (Si) has attracted a great deal of interest from researchers because of the numerous agronomic benefits of this element to plants. Indeed, silicon improves plant resistance to a range of biotic and abiotic stresses, with consequent yield increases. Furthermore, it enhances resistance in several crops of great economic importance to diseases and insect pests. Until recently, the exact nature of protective effects of silicon in plants is uncertain. To date, two major defense mechanisms due to silicon application have been documented: physical defense and biochemical defense. In this review, the interaction between silicon-treated-plants and reduced biotic stresses (disease and insect pests) incidence was explored. The current research presents the agronomic importance of silicon in plants, the control of fungal and bacterial pathogens and insect pests according to their lifestyle, and viral agents, and different mechanisms of silicon-enhanced resistance. By regrouping the data presented in this paper, a good knowledge of the association between silicon treatment, increasing plant resistance, and decreasing biotic stresses occurrence could be achieved.

“…113,122 Synergism of imidacloprid with organic silicon is more effective against this pest than imidacloprid alone. 123 The efficacy of imidacloprid and acetamiprid increased over time and reduced the oviposition duration and fecundity of P. solenopsis at sublethal doses. 122 Laboratory evaluation of the toxicity of different neonicotinoid insecticides showed variable degrees of efficacy against P. solenopsis.…”

The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), is a highly invasive and harmful pest. It causes considerable loss of cotton crops in China, India and Pakistan. Little is known about its bionomics since it was first recorded in Pakistan and India in 2005. Rapid spread of this pest worldwide has accelerated research on its biology, ecology and management. The P. solenopsis has a short life cycle, and optimal temperatures lead to an increase in the number of generations per year, which is a serious threat to cotton crop production. Cotton mealybug is native to the USA, although it has now spread to >43 countries. Insecticidal control is the primary and dominant practice for this pest, and its resistance to commonly used insecticides is increasing. Biocontrol agents have strong potential for the management of nymphal instar stages. We read >250 articles related to our review title and finally reviewed recent advances in the understanding of P. solenopsis biology, ecology and control approaches, aiming to highlight integrated and biological management practices of this pest.

“…Furthermore, it has been demonstrated that the elicitors (biocompatible molecules) can exhibit remarkable resistance against insect pest damage in combination with silicon, for example, the insect growth regulator lufenuron in affecting the preference of the fall armyworm Spodoptera frugiperda Smith (Lepidoptera: Noctuidae) on maize (Neri et al, 2005), fungicide acibenzolar-S-methyl (ASM) in reducing the larval period and pupal weight and increased the pupal period of the leaf-worm Alabama argillacea Hubner (Lepidoptera: Noctuidae) (Tomquelski et al, 2007) on cotton, ASM in reducing weight of the sunflower caterpillar Chlosyne lacinia saundersii Doubleday and Hewitson (Lepidoptera: Nymphalidae) larvae on sunflower (Assis et al, 2015), and systemic insecticide imidacloprid in decreasing the mealy-bug third-instar Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) nymphs and adult females on Portulaca grandiflora plants (Huang et al, 2014).…”

Silicon (Si) is reported to improve plant resistance to a range of biotic and abiotic stresses, with consequent yield increases. Silicon plays an important role in providing defense for crops of great economic importance against insect pests attack. In this study, the interaction between plants treated with silicon and reduced insect damage was reviewed. The current review presents the agronomic importance of silicon in plants, the control of insect pests in different major crop plants by silicon treatment, the different mechanisms of silicon-enhanced resistance, and the absence of silicon effects on insect pests. By integrating the data presented in this paper, a good knowledge of the association between silicon treatment, increasing plant resistance, and decreasing insect pest damage could be attainted.
