Control of insect vectors and plant viruses in protected crops by novel pyrethroid-treated nets

Abstract

LLITNs of appropriate mesh size can become a very valuable tool in combination with biocontrol agents for additional protection against insect vectors of plant viruses under IPM programmes.

Impact of long-lasting insecticide-incorporated screens onColorado potato beetle and plum curculio

“…A few studies have evaluated LLISs for control of agricultural pests (Moreno et al, 2012;Dáder et al, 2015;Kuhar et al, 2017). In these studies, the applicability of LLISs for multiple economically important pests and their potential for reducing insecticide dependency in horticultural and open field agricultural systems were evaluated.…”

Efficacy of a long‐lasting bifenthrin‐treated net against horticultural pests and its compatibility with the predatory mite Amblyseius swirskii and the parasitic wasp Eretmocerus mundus

“…To our knowledge, the first report concerning selectivity of these nets comes from our research group. Recent assays in small tunnels (8 m long × 6.5 m width × 2.6 m high) with a cucumber crop have shown that a bifenthrin‐treated net (3.8 g kg −1 ; 0.46 mm 2 hole size) is compatible with the parasitoid Aphidius colemani Viereck (Hymenoptera: Aphidiinae) and reduces Aphis gossypii Glover (Hemiptera: Aphididae) population density and the spread of two aphid‐transmitted viruses [ Cucumber mosaic virus (CMV) and Cucurbit aphid‐borne yellows virus (CABYV)] …”

Deltamethrin-Incorporated Nets as an Integrated Pest Management Tool for the Invasive Halyomorpha halys (Hemiptera: Pentatomidae)

“…In particular, pyrethroidincorporated nets applied as floating row covers, or 2-m high fences, have been shown to be efficacious for control of various lepidopteran and aphid pests of vegetables (Martin et al 2006, Licciardi et al 2008, Dader et al 2015, and are considered to be costeffective because they control multiple key pests, last multiple years, and because larger mesh sizes can be used compared with untreated row covers (Dader et al 2015). To our knowledge, the efficacy of LLINs for control of pestiferous stink bugs (Hemiptera: Pentatomidae) has not been investigated.…”
