“…First, the number of insects that invade the enclosed structure is lower due to more UV reflectance emitted by the sky or reflected from the photoselective materials that cover the greenhouses. Second, the light environment created inside alters the normal behavior of insects, thus resulting in reduced flight activity, which could explain why aphids occupied significantly fewer plants and were aggregated on the control plants in our experimental conditions (Raviv & Antignus, ; Antignus, ). Aphids sought hosts and oriented better in an environment rich in UV‐A and UV‐B, had a poor colonization inside the UV‐deficient cage, and an intermediate response in treatment +UV‐B, so it is likely that both fractions are equally important in direct aphid flight activity.…”

“…Within this process, visual cues are of major importance, especially for aphids because their orientation, host finding, and performance is very sensitive to changes in the amount and type of UV radiation present in the environment (Raviv & Antignus, ; Döring & Chittka, ). Several studies have highlighted how absence of UV in the environment can interfere with the ability of aphids to locate their hosts (Raviv & Antignus, ; Johansen et al., ; Antignus, ), and decreases their performance (Chyzik et al., ; Legarrea et al., ). In this sense, visual manipulation of the environment with photoselective screens has resulted in a novel means of aphid and virus control, with positive outcomes for horticultural crops of economic interest (Díaz & Fereres, ; Legarrea et al., ; Antignus, ).…”

Visual cues leading to host selection and landing are of major importance for aphids and evidence suggests that flight activity is very dependent on ultraviolet (UV)-A radiation in the environment. At the same time research on insect plant hosts suggest that the UV-B component can deter some pests via changes in secondary metabolite chemistry. Here, we examine the potential of UV (UV-A/UV-B) radiation to control insect pests in the glasshouse environment. We first examined artificial exposure to UV-B and the potential to trigger morphological and biochemical modifications in pepper (Capsicum annuum L., Solanaceae) with implications for the fitness of green peach aphid, Myzus persicae Sulzer (Hemiptera: Aphididae). UV-B caused accumulation of leaf secondary metabolites and soluble carbohydrates, and stimulated photosynthetic pigments. However, UV-B did not impact on foliar protein content and aphid performance was unaffected. Next, we studied how altering the UV-A/UV-B ratio environment affected aphid orientation and spatial distribution over time, either directly or by exposing plants to supplemental UV before insect introduction. Aphids directly settled and dispersed on their host pepper plants more readily in the presence of supplemental UV-A and UV-B. In the control treatment with ambient glasshouse UV-A and UV-B, insects remained more aggregated. Furthermore, insects were less attracted to peppers pre-exposed to supplemental UV-A and UV-B radiation. Our results suggest that suppression of UV-A and UV-B inside the protected environment reduces aphid colonization and dispersal. Furthermore, application of moderate exposure of young pepper plants to supplemental UV-B radiation could aid in protection from the colonization by phytophagous insectsPeer reviewe

“…These contrasting results may be due to different aspects, such as the timing of the survey and the impact of the net on the visual cues of predators. Disrupting insect fly orientation, visual detection and colour perception might reduce the attractiveness of yellow sticky traps and render this monitoring technique ineffective, 32 as observed in Candian et al 12 Mesh size is critical not only for the effectiveness of exclusion, but also for the microclimate occurring under the net. Despite expectations, under the pearl net, temperature and relative humidity were similar to those recorded outside the net (data not shown).…”

BACKGROUND Frequent pesticide treatments in fruit orchards increase hazards for workers, consumers and the environment. Moreover, the indiscriminate and excessive use of pesticides often induces resistance in pests. In the past few years, physical exclusion strategies have been proposed as an alternative for the control of insect pests. The goal of this study was to evaluate the effectiveness of anti‐hail photoselective netting in protecting apples against key and emerging pests, as well as the impact on beneficial arthropods, fungal diseases and fruit quality. RESULTS In netted plots, a significant reduction in pest populations, i.e. fruit moths, Halyomorpha halys (Stål) and Drosophila suzukii (Matsumura), was recorded in comparison with un‐netted controls. Moreover, the damage on fruits caused by H. halys was reduced up to 62% compared with insecticidal treatments. The net did not negatively affect the abundance of predators and the incidence of post‐harvest rot. In addition, the incidence of bitter pit on apple was reduced up to 52%. Furthermore, fruit quality was unaffected by the net coverage (both at harvest and after 4 months of storage). CONCLUSION Anti‐hail photoselective pearl netting proved a promising exclusion system that can prevent attack by more than one insect pest at a time, allowing for a strong reduction in insecticide treatments and relative costs. At the same time, the netting did not negatively influence the presence of predators, the incidence of fungal disease or fruit quality. © 2019 Society of Chemical Industry

“…Although pest management has historically involved the use of olfactory behavioural disruptors, such as pheromones, the application of different coloured reflective surfaces has also been studied to some extent to investigate behavioural changes mediated by the modification of insects' visual perception of its host (Prokopy and Owens 1983). For aphid pests, reflective mulches placed on the ground have been used to reduce the damage caused by several species, with important consequences for the reduction of insect-borne viruses on a range of crops worldwide (Antignus 2014). Despite these benefits, the dramatic increase in the use of plastic reflective materials in agro-ecosystems during the last 10 years has raised major agronomic, economic and environmental concerns related to their removal and disposal (Kasirajan and Ngouajio 2012).…”

Global concern about external costs of pesticides (environment and human health) has promoted the development of new strategies for pest control in agro-ecosystems. In this sense, mineral-based dust and optical barriers have been used against agricultural pests in a variety of crops worldwide as alternatives to orthodox pest control. Recently, mussel shells' optical properties have been investigated, suggesting their potential role in pest control as an optical barrier. In the present study, the effects of hydrophobic particle films, diatomaceous earths and mussel shells were evaluated for their potential in reducing the endemic New Zealand scarab Costelytra zealandica damage in vineyards. Feeding deterrents significantly reduced its damage by 46% when applied to Pinot Noir vines. In addition, vines treated with mussel shells had 69% fewer beetles on them. When hydrophobic particle films and mussel shells were evaluated in the same experiment, 33 and 73% reduction in damage was achieved by these two treatments, respectively. Furthermore, the addition of mussel shells increased grape yield by 28%. Here we demonstrate that mussel shells applied in the under-vine areas altered the flying and landing behaviour of a melolonthine pest. This is the first reported example of "waste" mollusc shells changing insect pest behaviour, highlighting their potential use in sustainable pest control programmes. Therefore, this approach might contribute to reducing the damage caused by other Scarabaeidae beetles with similar flight behaviour around the world.
