“…Resistance to diverse classes of pyrethroids has also been reported in populations from Benin (west Africa)71. In southern France, pyrethroid-resistance H. armigera was also reported7273, while populations resistant to pyrethroids, organophosphates and carbamates were identified in Spain7475. Significant reduced susceptibility to Cry1Ac has also been detected in some Chinese H. armigera populations76, and H. armigera larvae on Bt cotton (BG-II) which has cry1Ac + cry2Ab genes exists in India77.…”

The Old World bollworm Helicoverpa armigera is now established in Brazil but efforts to identify incursion origin(s) and pathway(s) have met with limited success due to the patchiness of available data. Using international agricultural/horticultural commodity trade data and mitochondrial DNA (mtDNA) cytochrome oxidase I (COI) and cytochrome b (Cyt b) gene markers, we inferred the origins and incursion pathways into Brazil. We detected 20 mtDNA haplotypes from six Brazilian states, eight of which were new to our 97 global COI-Cyt b haplotype database. Direct sequence matches indicated five Brazilian haplotypes had Asian, African, and European origins. We identified 45 parsimoniously informative sites and multiple substitutions per site within the concatenated (945 bp) nucleotide dataset, implying that probabilistic phylogenetic analysis methods are needed. High diversity and signatures of uniquely shared haplotypes with diverse localities combined with the trade data suggested multiple incursions and introduction origins in Brazil. Increasing agricultural/horticultural trade activities between the Old and New Worlds represents a significant biosecurity risk factor. Identifying pest origins will enable resistance profiling that reflects countries of origin to be included when developing a resistance management strategy, while identifying incursion pathways will improve biosecurity protocols and risk analysis at biosecurity hotspots including national ports.

“…The phenomenon in S. exigua is often due to more than one reason. The development of insecticide resistance is primarily a result of the selection pressure exerted on sprayed populations increasing the frequency of resistant individuals (Torres-Vila et al 2002). In three regions, the conventional insecticides were widely used to control several pests including S. exigua for many years.…”

Spodoptera exigua (Hübner) collected from three regions (two scallion-producing regions and one ginger-producing region) in Shandong, China and a laboratory colony of Wuhan (WHLC) were evaluated for their susceptibilities to ten insecticides (emamectin benzoate, chlorfenapyr, indoxacarb, spinosyn, tebufenozide, methoxyfenozide, chlorfluazuron, betacypermethrin, chlorpyrifos and methomyl) in 2008, 2009 and 2010 using a leaf-dip bioassay method. The results indicate that the resistance ratios of S. exigua to newer insecticides such as emamectin benzoate, chlorfenapyr and indoxacarb were all below 20-fold, with no obvious change in all 3 years. S. exigua exhibits moderate resistance to spinosyn, and its resistance ratios increased from 1.98-5.31-fold in 2008 to 14.31-64.20-fold in 2010 from three regions as compared with WHLC. S. exigua showed moderate to high resistance to insect growth regulators such as tebufenozide, methoxyfenozide, chlorfluazuron in 2008, 2009 and 2010, in which resistance to chlorfluazuron was rapidly increased from 31. 49-88.19-fold in 2008 to 1184.39-2789.67-fold in 2010. Resistance of S. exigua to beta-cypermethrin and chlorpyrifos varied greatly among the three regions, ranging from 95. 31-437.97-fold and 25.05-40.64-fold in 2008, 951.81-1304.40-fold and 44.91-186.33-fold in 2009, to 27.27-1095.31-fold and 19.12-267.98-fold in 2010. In contrast, S. exigua showed low resistance to methomyl, and the resistance ratio was below 5-fold in 3 years. There are several reasons accounting for varying degrees of resistance, including selection pressure, cropping structure and migration, in which the migration of S. exigua may play an important role.

“…This selective pressure exerted by the insecticides abruptly increases the frequency of the genetic condition expressed as resistance within the exposed population. The development of resistance is a result of the selection pressure exerted on sprayed populations increasing the frequency of resistant individuals (Torres-Vila et al 2002), but several factors including temperature are also involved in influencing the evolution of insecticides resistance (Raymond and Marquine 1994). At present, the extensive use of conventional insecticides such as organophosphate, carbamate and pyrethroids against S. litura has produced prevalent resistance in China (Wu et al 1995; Huang et al 2006).…”

Field resistance of Spodoptera litura (Lepidoptera: Noctuidae) to organophosphates, pyrethroids, carbamates and four newer chemistry insecticides in Hunan, China

The present studies were carried out to evaluate resistance in the populations of Spodoptera litura Fab. (Lepidoptera, Noctuidae) from five districts of Hunan Province in China to various insecticides from 2010 to 2012 using a standard leaf dip bioassay method. For organophosphates and pyrethroids, resistance ratios compared with a susceptible Lab-BJ strain were in the range of 14–229-fold for organophosphates and 12–227-fold for pyrethroids. Similarly, relative low levels of resistance to emamectin, indoxacarb, and chlorfenapyr were observed in all five populations. In contrast, the resistance to carbamates (thiodicarb or methomyl) was significantly higher than that of organophosphates, pyrethroids and newer chemistry insecticides. The pairwise correlation coefficients of LC50 values indicated that the newer chemistry insecticides and old generation insecticides were not significant except abamectin, which was negatively significantly correlated with methomyl. A significant correlation was observed between thiodicarb, methomyl, and deltamethrin, whereas resistance to bifenthrin showed no correlations with resistance to other insecticides except deltamethrin. The results are discussed in relation to integrated pest management for S. litura with special reference to management of field evolved resistance to insecticides.
