Abstract In October 2020, Liriomyza huidobrensis (serpentine leafminer [SLM]) was first detected in Western Sydney, New South Wales (NSW), and subsequently Southern Queensland (QLD). Control failures were reported, insecticide resistance confirmed via bioassay, but mechanisms causing remained unknown. We characterised the complete mRNA sequence of eight target genes L. using RNA sequencing. found that Australian SLM carries three mutations (I129V, G227A F331W) acetylcholinesterase ( AChE ) gene, to mode action (MOA) 1 chemicals; one mutation (A301S) gamma‐aminobutyric acid receptor subunit beta GABAR ), MOA 2 two (M918T L1014L) voltage‐gated sodium channel VGSC 3 chemicals. consequently developed a multiamplicon‐sequencing panel screen 234 field‐collected samples next‐generation The multiplex includes mitochondrial cytochrome oxidase COI for species identification , glutamate‐gated chloride GluCl chitin synthase CHS1 gene mutations. confirm all individuals carry multi‐resistance alleles homozygous fixed state. This is rare phenomenon single individual be multiple mutations, with only few studies documenting such at population level. Such mechanism detection raises concern there are limited chemical options control invasive Australia.

Field evolved resistance to insecticides is one of the main challenges in pest control. The fall armyworm (FAW) a lepidopteran species causing severe crop losses, especially corn. While native Americas, presence FAW was confirmed West Africa 2016. Since then, has been detected over 70 countries covering sub-Saharan Africa, Middle East, North South Asia, Southeast and Oceania. In this study, we tested whether invasion accompanied by spread mutations from invasive areas. We observed that Bt at ABCC2 genes were only populations where initially reported. Invasive found have higher gene numbers cytochrome P450 than proportion multiple acetylcholinesterase genes, supporting strong selective pressure for against synthetic insecticides. This result explains susceptibility various Chinese populations. These results highlight necessity regular standardized monitoring insecticide using both genomic approaches bioassay experiments.

FAW control largely relies on application chemical insecticides transgenic crops expressing Bacillus thuringiensis insecticidal proteins.

Abstract Background The Fall armyworm (FAW) Spodoptera frugiperda (Lepidoptera: Noctuidae) is now established across the African continent and a highly polyphagous destructive pest of many crops. In Uganda, FAW has become major maize pest, causing heavy damage especially on shoots growing points. objectives this study were to: (i) document local farming practices that have been useful to manage FAW, (ii) establish farmers’ perspective time FAW’s arrival their localities, (iii) investigate economic impact (yield) farmers, (iv) perception current status (v) alternative used perceived efficacies. Methods A questionnaire survey was undertaken in November 2020 Kamuli Namutumba districts Uganda 99 farmers interviewed understand profiles perceptions about FAW. descriptive analysis data socio-economic farmers. Results Farmers’ education levels two ranged from basic (completed primary education) advanced University degree), with most having 10–30 years experience (F = 20.8; df 3,7; P 0.0067), mainly small- mid-sized production scales 436.2; 2,5; 0.0002). Famers (98%) (96%) reported 25–50% yield losses due infestation negatively impacted income. We found significantly higher percentage (84% 92% districts, respectively), could correctly identify by its appearance ( < 0.0001). While officially 2016, confirmed noticing symptoms similar those caused as early 2013 2014 respectively. 98% 96% strongly agreed reduced income, while 74% 86% also considered threat majority (64% Kamuli, 82% Namutumba) still be very serious challenge six since being Uganda. To 84% 90% respondents respectively, predominantly use chemical control methods. Other methods included cultural (i.e., regular weeding handpicking), biological extracts (pepper, tobacco, Aloe-vera, Lantana, sisal) evident though not common. Pheromones reported, although farmer district reportedly observed weaver birds Ploceus spp.) predating maize. small number (ca. 4%) both took no intentional action against Conclusions believe they can if appropriate efficacious insecticides are able apply them follow recommended procedures. advocated for an area-wide approach one best alternatives invasive pest.
