“…Further, when insecticide use is not rotated effectively, resistance to compounds can develop rapidly among the different whitefly vector haplotypes. Shifts in the predominant whitefly haplotype vector(s) of begomoviruses in cotton-vegetable systems in Pakistan can lead to the accelerated spread of certain begomovirus variants over others ( Paredes-Montero et al., 2019 ; Shah et al., 2020 ).…”

“…The control of whiteflies is based conventionally on synthetic pesticides including carbamates, organophosphates, and pyrethroids [331]. The continuous application of these chemicals in larger quantities has led to the development of resistance by B. tabaci [332,333]. Thus, development of insecticide resistance is a major challenge in WFM and once they develop such a resistance, it becomes difficult to control.…”

The whitefly (Bemisia tabaci Gennadius) is a notorious devastating sap-sucking insect pest that causes substantial crop damage and yield losses due to direct feeding by both nymphs and adults and also through transmission of viruses and diseases. Although the foliar application of synthetic pesticides is crucial for efficient control of B. tabaci, it has adverse effects such as environmental pollution, resistance and resurgence of the pest, toxicity to pollinators, and crop yield penalty. Thus, a suitable, safe, and robust strategy for the control of whiteflies in the agricultural field is needed. The reports on whitefly-resistant transgenic plants are scanty, non-reproducible, and/or need secondary trials and clearance from the Genetic Engineering Appraisal Committee (GEAC), the Ministry of Environment and Forests (MoEF), and the Environmental Protection Agency (EPA). The present review encompasses explicit information compiled from 364 articles on the traditional, mechanical, biological, biotechnological, and chemical strategies for whitefly management (WFM), IPM strategy, and future prospects of WFM for food and agriculture security.

“…Bemisia tabaci (Hemiptera: Aleyrodidae), commonly known as silverleaf whitefly, comprises at least 44 cryptic species that are morphologically indistinguishable [18], and is considered one of the most destructive agricultural pests with more than 600 host plant species around the world [19], causing major losses to commercial crops including sweet potato, tomatoes and cucurbits [20][21][22]. Both nymphs and adults feed on the plants phloem and excrete honeydew which can lead to black mold growth on the leaves [16,23].…”

“…The fast development rate of these three pests favors a quick rise in the population causing a rapid decline in host plants [19,27,28]; the role of R. maidis and B. tabaci in the transmission of plant disease causing virus as well as mold growth, and the indiscriminate and abusive use of synthetic pesticide that benefits the rapid rising in resistance, such as the reported for B. tabaci and T. urticae, make their control a priority for farmers [20,[29][30][31][32][33][34].…”

Pest control is a main concern in agriculture. Indiscriminate application of synthetic pesticides has caused negative impacts leading to the rapid development of resistance in arthropod pests. Plant secondary metabolites have been proposed as a safer alternative to conventional pesticides. Monoterpenoids have reported bioactivities against important pests; however, due to their high volatility, low water solubility and chemical instability, the application of these compounds has been limited. Nanosystems represent a potential vehicle for the broad application of monoterpenoids. In this study, an 1,8-cineole nanoemulsion was prepared by the low energy method of phase inversion, characterization of droplet size distribution and polydispersity index (PDI) was carried out by dynamic light scattering and stability was evaluated by centrifugation and Turbiscan analysis. Fumigant bioactivity was evaluated against Tetranychus urticae, Rhopalosiphum maidis and Bemisia tabaci. A nanoemulsion with oil:surfactant:water ratio of 0.5:1:8.5 had a droplet size of 14.7 nm and PDI of 0.178. Formulation was stable after centrifugation and the Turbiscan analysis showed no particle migration and a delta backscattering of ±1%. Nanoemulsion exhibited around 50% more bioactivity as a fumigant on arthropods when compared to free monoterpenoid. These results suggest that nanoformulations can provide volatile compounds of protection against volatilization, improving their bioactivity.
