Western flower thrip, Frankliniella occidentalis (Pergande), is among the most economically important agricultural pests globally, attacking a wide range of vegetable and horticultural crops. In addition to causing extensive crop damage, the species is notorious for vectoring destructive plant viruses, mainly belonging to the genera Orthotospovirus, Ilarvirus, Alphacarmovirus and Machlomovirus. Once infected by orthotospoviruses, thrips can remain virulent throughout their lifespan and continue transmitting viruses to host plants when and wherever they feed. These irruptive viral outbreaks in crops will permanently disrupt functional integrated pest management systems, and typically require a remedial treatment involving insecticides, contributing to further development of insecticide resistance. To mitigate against this continuing cycle, the most effective management is early and comprehensive surveillance of the pest species and recognition of plant viruses in the field. This review provides information on the pest status of F. occidentalis, discusses the current global status of the viruses vectored by this thrip species, examines the mechanisms involved in transmitting virus-induced diseases by thrips, and reviews different management strategies, highlighting the potential management tactics developed for various cropping systems. The early surveillance and the utilization of potential methods for control of both F. occidentalis and viruses are proposed.

“…Studies on cucumbers (Cucumis sativus L.) and African eggplants (Solanum macrocarpon L.) demonstrated the efficacy of pyrethroid-treated nets in the management of aphids and Lepidoptera, although providing lower efficacy in containing tiny insects such as whiteflies (Trialeurodes vaporarium) and thrips (Frankliniella occidentalis) [43,44]. In a recent trial, Arthurs et al [45] tested the exclusion performance of a two-colored modern long-lasting insecticide net (LLIN) with a larger mesh size (32 holes/cm 2 ) compared to a conventional thrips exclusion screen. The results showed lower thrips penetration in yellow-treated nets than in black ones.…”

Environmental pressure poses a major challenge to the agricultural sector, which requires the development of cultivation techniques that can effectively reduce the impact of abiotic stress affecting crop yield and quality (e.g., thermal stress, wind, and hail) and of biotic factors, such as insect pests. The increased consumer interest in premium-quality vegetables requires the implementation of sustainable integrated pest management (IPM) strategies towards an ever-increasing insect pressure, also boosted by cultivation under protected structures. In this respect, insect nets represent an excellent, eco-friendly solution. This review aims to provide an integrative investigation of the effects of the insect screens in agriculture. Attention is dedicated to the impact on growth, yield, and quality of vegetables, focusing on the physiological and biochemical mechanisms of response to heat stress induced by insect screens. The performance of insect nets depends on many factors—foremost, on the screen mesh, with finer mesh being more effective as a barrier. However, finer mesh nets impose high-pressure drops and restrict airflow by reducing ventilation, which can result in a detrimental effect on crop growth and yield due to high temperatures. The predicted outcomes are wide ranging, because heat stress can impact (i) plant morpho-physiological attributes; (ii) biochemical and molecular properties through changes in the primary and secondary metabolisms; (iii) enzymatic activity, chloroplast proteins, and photosynthetic and respiratory processes; (iv) flowering and fruit settings; (v) the accumulation of reactive oxygen species (ROSs); and (vi) the biosynthesis of secondary biomolecules endowed with antioxidant capacity.

“…The establishment of insect proof nets for the stored product pest management is directly linked to environmental protection, as their use does not lead to residues or to contamination in storage facilities and stored commodities [ 17 ]. Many studies are focused on the design of long-lasting insecticide- treated nets (LLINs) by incorporating insecticides into the net coating in order to minimize the chemical sprays directly on the crop [ 18 , 19 ]. Dáder et al [ 18 ] showed that LLINs caused a significant reduction in Myzus persicae (Sulzer) (Hemipetra: Aphidedae) and Aphis gossypii (Glover) (Hemipetra: Aphididae) immigration without affecting the parasitoid Aphidius colemani Viereck (Hymenoptrea: Aphididae).…”

“…However, during field trials, LLINs effectiveness was degraded after sun exposure whereas, the efficacy of either bifenthrin or deltamethrin was suggested as insufficient to control B. tabaci culture due to its small size. Notwithstanding, according to Arthurs et al [ 19 ], nettings of large mesh size treated with deltamethrin proved insufficient to protect a greenhouse crop from F. occidentalis invasion. Hence, both the effect of LLINs on beneficial enemies and their effectiveness in small sized insects should be further evaluated [ 18 ].…”

“…Recently, Shoaib et al [ 29 ], indicated that the exposure of larvae of Plutella xylostella (L.) (Lepidoptera: Plutellidae) to 1 mg × cm −2 of a siliceous dust formulation resulted in 85% mortality after 72 h. The authors suggested that the mortality rate is improved as dose and exposure interval are increased. Moreover, silica nanoparticles, concerning their physical and chemical properties, differ significantly from their bulk formation [ 19 ]. According to Debnath et al [ 30 ], nanoparticles proved to be much more effective when compared with bulk silica against S. oryzae .…”

Insect proof nets are widely used in agriculture as mechanical and physical barriers to regulate pest populations in a greenhouse. However, their integration in the greenhouse ventilation openings is highly associated with the decrease of air flow and the adequate ventilation. Thus, there is need for alternative pest management tools that do not impair adequate ventilation. In the present study, we tested four net formulations of relatively large mesh size coated with SiO2 nanoparticles, namely, ED3, ED3-P, ED5, and ED5-P to evaluate their insecticidal properties against adults of Aphis fabae and Sitophilus oryzae and larvae of Tribolium confusum. ED3 and ED5 nets were coated with SiO2 nanoparticles of different diameter, while in the case of ED3-P and ED5-P, paraffin was added to increase the mass of the deposited particles on the net’s surface. In the first series of bioassays, the knockdown and mortality rates of these species were evaluated after exposure to the aforementioned net formulations for 5, 10, 15, 20, 25, 30, 60, 90, and 180 min. In the second series of bioassays, knockdown and mortality of these species were recorded after 1, 7, and 10 days of post-exposure to the nets for different time intervals (15, 30, and 60 min). Based on our results, all nets significantly affected A. fabae, since all insects were dead at the 1-day post-exposure period to the silica-treated nets. Conversely, at the same interval, no effect on either S. oryzae adults or T. confusum larvae was observed. However, in the case of S. oryzae, the efficacy of all nets reached 100% 7 days after the exposure, even for adults that had been initially exposed for 15 min to the treated nets. Among the species tested, T. confusum larvae exhibited the lowest mortality rate, which did not exceed 34% at the 10 days of post-exposure interval. Our work underlines the efficacy of treated nets in pest management programs, under different application scenarios, at the pre- and post-harvest stages of agricultural commodities.
