“…Neonicotinoids are also commonly applied to a variety of Australian vegetable crops and have become widespread in grain crops as a seed coating before sowing. Relatively lowlevel resistance to organophosphates (20-fold) and synthetic pyrethroids (4 Ð15-fold) were Þrst detected in Australian populations of M. persicae in the mid1970s from peach and potato crops (Attia and Hamilton 1978). Subsequently, Herron et al (1993) reported organophosphate resistance levels (40-fold) and low-levels of tolerance to carbamates (20-fold) in M. persicae populations from stone fruit.…”

The green peach aphid, Myzus persicae (Sulzer), is a serious pest throughout the world, attacking a broad range of crop plants across numerous agricultural industries. This species has a high propensity to develop chemical resistance, and has the unenviable title of having resistance to more insecticides than any other insect species. An extensive survey of field populations was undertaken across Australia, and showed widespread and high levels of resistance to carbamates and synthetic pyrethroids in M. persicae. Moderate levels of resistance to organophosphates were also observed in many populations, while there is new evidence of resistance developing to neonicotinoids. Isofemale (clonal) lines of M. persicae were generated and subsequently tested across a range of insecticides; individual genetic clones were found to contain resistance to multiple chemical classes. Resistance genotyping of these aphids were consistent with published literature of known resistant mechanisms. The high and widespread levels of resistance identified within Australia are concerning. Resistance in M. persicae has spread quickly across Australia, and thus farmers are likely to have fewer chemical control options in the future. There is a need to develop resistance management strategies that rotate insecticides, spray insecticides only when economically necessary, and incorporate nonchemical control options.

“…This could indicate either that the current FFCs for these insecticides have simply been set below the optimum level, or it could reflect the development of resistance. The locations where we collected infested nuts were surrounded by orchards with a history of insecticide usage, and the development of resistance in response to frequent indoxacarb and acephate applications has been identified in a number of other insect species including the green peach aphid, Myzus persicae Sulzer (Attia & Hamilton, 1978), oblique banded leafroller, Choristoneura rosaceana Harris (Ahmad et al., 2002), diamondback moth, Plutella xylostella L. (Zhao et al., 2006) and the tarnished plant bug, Lygus lineolaris Palisot de Beauvois (Snodgrass et al., 2009). Our study cannot confirm or refute resistance to the tested insecticides in K. macadamiae , and a comparative toxicological study using weevil strains from different localities should be conducted.…”

This study investigated the interactions between insecticides (acephate and indoxacarb) and fungal entomopathogens (Beauveria bassiana [Bals.‐Criv.] Vuill. strain B27, Metarhizium anisopliae [Metschn.] Sorokin strain ECS1, and a commercial B. bassiana product, Velifer® Biological Insecticide) for controlling the macadamia seed weevil, Kuschelorhynchus macadamiae Jennings and Oberprieler, in the laboratory and glasshouse. In the laboratory, additive interactions between insecticides at their full field concentrations (776 mg AI/L of acephate and 75 mg AI/L of indoxacarb) and fungal entomopathogens at 107 conidia/ml (ECS1 and B27) or at full field concentration (0.5 ml of Velifer®/L) were seen at 6 days and 12 days post‐application. Under the same experimental conditions, synergistic interactions against K. macadamiae were observed 6 days post‐application when fungal entomopathogens at 2.5 × 106 conidia/ml or at 25% of full field concentration (Velifer®) were co‐applied with insecticides at 25% of their full field concentrations, whilst additive interactions were again observed at 12 days post‐application. In the glasshouse, additive interactions between insecticides (at full field concentrations) and fungal entomopathogens (at 107 conidia/ml, or at full field concentration for Velifer®) were obtained at 6 days and 12 days post‐application. The results from this study suggest that acephate and indoxacarb have both synergistic and additive effects against K. macadamiae when deployed together with fungal entomopathogens, depending on the initial concentrations of mixture components. Combined application of entomopathogens with compatible insecticides promises to provide more effective management of K. macadamiae than individual chemical applications.

Empowering Australian insecticide resistance research with genetic information: the road ahead

Insecticides are important for chemical control of arthropod pests in agricultural systems but select for resistance as an adaptive trait. Identifying the genetic mechanism(s) underpinning resistance can facilitate development of genetic markers, which can be used in monitoring programs. Moreover, understanding of genetic mechanisms in a broader population genetic context can be used to infer the origins of resistance, predict the dynamics of resistance evolution and evaluate the efficacy of different management strategies. Transitioning genetic information successfully into practical solutions requires overcoming two major hurdles. Firstly, genetic mechanisms must be identified to develop genetic markers. Secondly, routine use of genetic markers is required to build substantial spatio‐temporal data on the distribution and frequency of resistance alleles. In this study, we demonstrate large knowledge gaps on the genetic mechanisms of insecticide resistances in Australia using eight established arthropod pests important to the grains industry: Bemisia tabaci (silverleaf whitefly), Frankliniella occidentalis (western flower thrips), Halotydeus destructor (redlegged earth mite), Helicoverpa armigera (cotton bollworm), Myzus persicae (green peach aphid), Plutella xylostella (diamondback moth), Tetranychus urticae (two‐spotted spider mite) and Thrips tabaci (onion thrips). Many resistances have not been characterised at the genetic level in most pests, even for chemical MoA groups with a long history of use in Australia. Moreover, monitoring of resistance is spatio‐temporally patchy, which precludes examination of long‐term trends or predictive modelling. We suggest that leveraging cumulative global knowledge of resistances to develop a priori candidate genes, and incorporation of genomic approaches, can help overcome the hurdles of embracing genetic information in resistance management. We highlight the recently invasive Spodoptera frugiperda (fall armyworm) as a case study where genetic markers and genomic approaches should prove useful in rapidly assessing the risk of this species to the Australian grains industry and other agricultural commodities. The uptake of genetic information into management can only occur once its benefit to empower insecticide resistance research is fully realised. Ultimately, the road ahead requires amalgamation of multifaceted data (genes, environment and spatio‐temporal replication) to better understand and predict the dynamics of resistance evolution.
